1. Introduction.
1.1 Task specification
The implementation of the nuclear fuel cycle in the EFDA TIMES model, carried out during
the 2011 work program, has included the update of the new fission power plants (generation
III+ and IV) economics according the most recent literature. The cost revision by experts has
lead to investment costs higher than before because of both the current economic crisis and
the better knowledge about the economics of Gen III+ power plants thanks to their recent first
steps towards deployment. Thus, the investment costs of fission power plants used in ETM
were found to be outdated and actually quite lower than real ones.
In light of this, in the framework of the EFDA TIMES model development and the results
dissemination, two main goals for the WP12 have been identified.
Firstly, a review and an update of the economics of the whole new power sector, namely the
set of power technologies entering the energy market from 2010, become necessary in order
to ensure a well-balanced competition between the already updated nuclear sector and the
other power technologies.
As far as the results dissemination, besides the mere presentation of alternative scenarios, a
comparison with the results from similar models is generally recommended to further
demonstrate their reliability through the detection of similarities. Within the TIMES
community, TIAM is the model most similar to ETM and their results are usually compared
even for a continuous consistency cross check of the assumptions behind the scenarios setting
up. Then, a detailed comparison of both the economics and the technical features
characterizing the electricity producing technologies in ETM and TIAM was required to
justify any possible differences in the energy mix resulting from similar runs of the two
models.
In the following a detailed description of the changes in the data featuring each technology
belonging to the power sector is reported. The literature sources of old data, which are
currently not always available or easily detectable, are specified any time it was possible and
the reasons of changes are fully clarified. Moreover a detailed report about the differences
between ETM and TIAM is given.
1.2 Overview of the methodology.
In ETM the model of the electricity generation sector should gather the all possible
technologies that could compose the power plant fleet of the 15 model regions from 2010 to
2100. Some of them are already available, others are still at the research phase (e.g carbon
capture and storage technologies, generation IV fission power plants, fusion power plants,
etc.). Thus a high level of uncertainty affects both technical and economical data of a part of
the technologies due to their intrinsic immaturity. Beside this, the technical and economical
parameters of the existing technologies, even well known, usually change depending on the
place where the plants are built. For example, the weather conditions influences the
availability factor of renewable while regional economies and financing have a great
influence on the economic competitiveness of technologies.
All this given, the electricity power sector in ETM should include a number of variants of the
same electricity generation technology to overcome the uncertainties of both the lack of
knowledge about future technologies and the differences between nations.
2
Therefore the same approach as that of the ―Energy Technology Perspectives‖ studies has
been used to update the model of the power sector. Namely, the economic and technical
features of the new technologies refer to plants in United States (with only few exceptions
due to lack of information) and cost data or availability factors in other world region is
endogenously by the model by multiplying these data by region-specific multipliers defined
by the user. The uncertainties about new technologies can be instead overcome only by
developing a number of alternative scenarios.
In the present study each technology is analysed following a fixed approach:
1) analysis of changes over three ETM model versions (before 2006, 2006 and 2012
versions) and detection of the data literature sources;
2) comparison with TIAM values;
3) data update according to the most recent literature.
In the following, after the explanations of conventions used in the study, a detail description
of the update of each technology’s feature is reported. A short description of the working
principle is also presented.

2. Conventions and key assumptions.
In ETM the features of the new electricity generating technologies are listed in two templates,
the ―Subres_NewTechs‖ and the ―Subres_Sequestration‖. The region-specific multipliers are
instead declared in the ―Subres_Trans‖.
In the ―Subres_NewTechs‖ the fossil fuelled power plants, the nuclear power plants and the
renewable are described by the following attributes:
- TechName : technology acronym;
- TechDesc : brief technology description;
- CommName : name of the input/output commodity of the technology;
- YEAR : year to which the technology description refers to;
- CAPUNIT : energy conversion factor;
- Output : attribute used to declare which ones of the commodities are outputs;
- START : year of technology deployment;
- LIFE : technical life of the technology;
3
- DISCRATE : discount rate;
- INVCOST : overnight or investment cost of the technology [$/kW];
- FIXOM : fixed O&M costs of the technology [$/kW/yr];
- VAROM : variable O&M costs of the technology [$/GJ];
- Input : inverse of efficiency;
- AF : availability factor;
The technologies for carbon capture and storage are instead treated separately in the second
template. Besides the attributes just listed, the following is requested to fully describe these
technologies:
- FLO_EMIS : emission factor of an emission commodity.
It’s worth to notice that in the current model version the retrofitting option is not present, so
the CCS is available only for new installed capacity.
Among the attributes listed above only the INVCOST has a double meaning since it can refer
to the overnight cost or the investment cost (i.e. overnight + IDC) of the technology. As
stated in the TIMES manual [9], in any TIMES model “[…] The investment cost should be
the overnight investment cost (excluding any interests paid during construction) whenever the
construction lead time is explicitly modeled […]. In such a case, the interests during
construction are endogenously calculated by the model itself, […]. If no lead-time is specified
(and thus cases 1 are used), the full cost of investments should be used (including interests
during construction, if any. […]Ideally, it would be desirable that cases 1 be used only for
those investments that have no lead time (and thus no interests during construction).
However, if a user employs cases 1 for projects even though there are significant IDC’s, the
latter should be included in the investment cost.”
In the previous ETM model version, the lead time has been never considered so the
INVCOST has been always treated as investment cost, although in some cases the cost data
were actually referring to overnight costs. This has made the capital intensive technologies
(e.g. nuclear power plants) cheaper than reality and increased their economic competitiveness
as well.
In TIAM it is explicitly declared that INVCOST refers to the overnight cost of the technology
[6]. In case of capital intensive technologies, namely hydro and nuclear, the construction time
is provided (10 years for nuclear, 10 years for dam, 5 years for run-of-river).
In the updated ETM template the lead time has been included as well:
- run-of-river, 1 year [1]
- gas-fired PP, 2 years [1]
- coal-fired PP, 4 years [1]
- nuclear PP, 5 years [11]
- dam, 10 years [6]
Nevertheless, in the case of short lead times (1 or 2 years), one gets the similar results if the
overnight cost is considered instead of the investment cost and no lead time is explicitly
declared. In fact, the investment cost is calculated by TIMES by using the approach of
4
case1.a [9]1 and the capacity becomes available in small quantity from the first year
2.
Therefore this approach leads to the same results as if a 1 year lead time was declared.
Therefore in the updated ETM, the overnight cost of run-of-river and gas fired power plants
are used instead of the investment costs.
On the other hand, the declaration of the lead time of coal fired power plants, nuclear power
plants and hydro (dam and run-of-river) is necessary not only to estimate their real cost of
capital3 but also to make the capacity available in a lump quantity at the end of the
construction period - as it usually happens in reality.
In order to make the model results comparable to the most known studies, the selected main
literature sources about costs and technical features are the latest version (2010) of ―Projected
cost of generating electricity‖ [1] and ―Energy Technology Perspectives‖ [3].
In both studies the technology’s overnight costs are reported but in the first they refer to
technologies that are going to be built in 15 worldwide nations, whereas in the ETP only the
costs in of plants in the United States are presented together with their guessed future
evolution. Therefore while both references are used to check the overnight and O&M costs of
technologies, reference [1] is used to check and update the region specific multipliers and
reference [3] to check and update the cost evolution from 2010 to 2050.
Moreover, the same capacity factors assumed in [1] is generally taken as reference as well as
the technology operational life.
Finally, a 3% inflation rate has been generally used to discount the costs to US$20004 being it
in line with assumption in [1]. The formula for the discounting is the following:
COST2000 = COSTy * (1+i) 2000 – y
where i is the inflation rate.
3. COAL FIRED POWER PLANTS
Technology PULVERIZED COAL – SUPER CRITICAL
―Pulverized Coal‖ (PC) plant is a term used for power plants which
burns pulverized coal in a boiler to produce steam that is then used to
generate electricity. PC plants designed to have steam conditions
below the critical point of water (about 22.1 MPa-abs) are referred to
as ―subcritical‖ PC plants, while plants designed above this critical
point are referred to as ―supercritical‖. ―Supercritical‖ typical design
conditions are: 24.2 MPa/565°C/565°C. ―Ultra-supercritical‖ plants
are design above these conditions. [13]
1 Since no lead time is declared and the technical life is higher than any time period length (minimum life of
technologies in ETM is 15 years while the minimum time period length is 5 years).
2 The capacity to be installed is equally spread over the number of years composing the same time period.
3 In ETM a linear construction cost profile is used as default. This means that the overnight cost is equally
distributed over the construction period. For more details see [11] (§ 4.1.1)
4 This is the default currency in ETM.
5
Acronym ECOAPUL105
Investment cost The overnight cost declared in 2006 version (1100 $/kW) probably
refers to a standard PF plant whose cost was presented in [5] (1000
$2003/kW =1110 $2000/kW). This value is likely to have been updated
in 2008 so that in ETM2012 the same technology costs 1500 $/kW:
the source is not documented, but it is likely to be [4] where the
average overnight cost is estimated to be 1700 $2005/kW = 1540
$2000/kW. In TIAM the overnight cost is even cheaper (1300 $/kW).
However, this cost is typical of an old-fashion coal power plant (PF
operating at less than SC steam conditions). New coal technologies
are SC and USC plants (Ultra Super Critical refers to a plant
operating with steam pressures greater than 221 bar and with steam
temperatures in excess of 600°C [1]) whose costs is presented in [3].
Being the costs and efficiency of the two kind of plants quite similar
([3], page 120) in ETM only the SC one is considered.
The new overnight cost of a coal supercritical power plant in ETM
is: 2100 $2008/kW = 1800 $2000/kW.
The cost is assumed to decrease by 21% in 2050 [3]and then remain
unchanged over the long term (1414 $/kW).
Lead time 4 years [1] (corresponding to a 16% capital cost increase)
O&M cost The value in 2012 model version (6.15 $/MWh) is not changed as it
is compromise between [1] and [3] (7 $2008/MWh = 6 $2000/MWh)
Capacity factor Is changed from 0.9 to 0.85 in line with [1].
Efficiency The same assumption of [3] is made (42% over the entire horizon)
instead of an increasing efficiency from 36% to 55%. A more
optimistic assumption is made in TIAM where the efficiency
increases from 47% to 52% in 2050.
Life Is maintained unchanged (40 years) as this assumption is in line with
[1]. In TIAM a shorter life in assumed (30 years).
Technology PULVERIZED COAL WITH CO2 REMOVAL FROM FLUE GAS
With post-combustion processes, CO2 is captures al low pressure
from flue gas that generally has a co2 content of 2% to 25%. The
challenge is to recover co2 form the flue gas economically. The
separated gas has to be compressed before transportation. [4]
Acronym EZCOA110
Investment cost The overnight cost of the ―base‖ technology (PC without CCS) has
been increased accordingly to the cost increase estimated by IEA [3]
6
(+62% in 2010, 52% in 2050 ).
Moreover the year of technology deployment has been changed from
2010 to 2020 since it is actually not yet deployed worldwide.
In TIAM the overnight cost is higher than previous ETM version but
more optimistic that IEA estimations.
Lead time 4 years [1] in keeping with the ―base‖ technology.
O&M cost Similarly to the overnight costs, the O&M costs of the ―base‖
technology have been increased by 143% in 2010 and 134% in 2050
as stated in [3].
Capacity factor Decreased from 90% to 85%, in line with the ―base‖ technology.
Efficiency The same assumptions of [3] have been used, namely 36% in 2010
raised to 44% in 2050. In the previous ETM version the efficiency
was lower in 2010 (33%) while higher in 2050 (48%). The new
value of fix and O&M costs are in line with TIAM.
Life Unchanged, 40 years, while in TIAM a shorter life is assumed (30
years).
Notes In TIAM the Pulverized coal technology with Oxyfuelling
(EZCOA110) is also considered. It’s recommended to add this
technology in ETM as well.
Technology INTEGRATED GASIFICATION COMBINED CYCLE (IGCC)
As Integrated Gasification Combined Cycle (IGCC) Power Plant in
its simplest form is a process where coal is gasified with either
oxygen or air, and the resulting synthesis gas, consisting of hydrogen
and carbon monoxide, is cooled, cleaned and fired in a gas turbine.
The hot exhaust from the gas turbine passes through a heat recovery
steam generator (HRSG) where it produces steam that drives a
turbine. Power is produced from both the gas and steam turbine-
generators. [13]
Acronym ECOACCO105
Investment cost Until 2006, in ETM two different IGCC technologies were modeled,
using air or oxygen as the oxidising medium. Since the same costs
were used, only one IGCC plant (oxygen blown) has been
considered in later ETM version (in the ETP the costs of a generic
IGCC plant is instead reported). On the contrary, in TIAM both
IGCC technologies are considered (one more expensive than the
other but having both the same efficiency).
The old data (ETM2006) probably refer to [2] (1500 $2003/kW =1400
7
$2000/kW); the ETM2012 data is instead undocumented. The costs in
TIAM are quite similar to that of the last ETM version.
The cost of the IGCC oxygen blown is updated according to [3]:
2400 $2008/kW = 2000 $2000/kW.
The cost is assumed to became 23% lower in 2050 [3] and to remain
unchanged over the long term (1542 $/kW).
Lead time 4 years [1] (corresponding to a 16% capital cost increase)
O&M cost The value in ETM2012 (7.7 $/MWh) is the mean between [1] and
[3] data.
Capacity factor Is changed from 0.9 to 0.85 in line with [1].
Efficiency The efficiency values until 2030 are not changed since they are in
line with the forecasts presented in [3]. After then (from 2040 to the
end of the time horizon) the efficiency value is instead kept
unchanged (53%).
Life Unchanged (30 years): a shorter life than that of conventional coal-
fired power plants is justified by the similarity of this technology to
natural gas combined cycle gas turbine (NGCC) whose life is set in
[1] to 30 years as well as all gas-fired power plants.
Technology INTEGRATED GASIFICATION COMBINED CYCLE (IGCC) WITH
CO2 REMOVAL FROM INPUT GAS
CO2 can be captured pre-combustion in coal or natural gas burning
plants. Reacting the fuel with air or oxygen enables the capture of
high concentration of CO2 (more than 95%).[4]
Acronym EZIGC1110
Investment cost The overnight cost of the ―base‖ technology (IGCC without CCS)
has been increased accordingly to the cost increase estimated by IEA
[3] (+33%).
Moreover the year of technology deployment has been changed from
2010 to 2020 since it is actually not yet deployed worldwide.
The overnight cost in TIAM is higher than that assumed in the
previous version of ETM but quite lower than the recent IEA
estimations.
Lead time 4 years as for the ―base‖ technology.
O&M cost Similarly to the overnight costs, the O&M costs of the ―base‖
technology have been increased by 33% as stated in [3].
8
Higher O&M cost are instead assumed in TIAM.
Capacity factor Decreased from 90% to 85%, in line with the ―base‖ technology
(IGCC without CCS).
Efficiency The same assumptions of [3] have been used (from 33% in 2010 to
48% in 2050 vs a fixed value of 40% over the entire time horizon in
the previous ETM version).
In TIAM the efficiency in 2010 is higher than IEA data but both
converge to 48% in the long term.
Life Unchanged (30 years)
Note In the previous ETM version also the IGCC with Co2 removal from
flue gas was included. Nevertheless, being its features the same of
the IGCC with Co2 removal from input gas with the exception of the
costs which were higher, the model will never choose it. This is why
this technology has been considered redundant.
Technology FLUIDIZED BED COMBUSTION – PRESSURISED
The Fluidized Bed Combustion (FBC) is a combustion process in
which limestone is injected into the combustion zone to capture the
sulfur in the coal.
Acronym ECOACCO105
Investment cost Until 2006 version, in ETM two different FBC technologies were
modeled, atmospheric and pressurised, having quite similar
overnight cost (1245 $2000/kW and 1200 $2000/kW respectively). The
same distinction is kept in TIAM.
In latest ETM version only one FBC plant is modeled, namely the
pressurised one. The INV_COST is likely to have been taken from
[2] where the overnight costs of FBC plants to be built in Czech
Republic and Slovack Republic are indicated (data from paper
analysis). However the kind of bed, atmospheric or pressurised, is
not specified.
Economic data about this technology is not available in [3]. Thus in
the updated ETM version, the overnight cost of a FBC plant, labelled
as pressurised but actually referring to a generic FBC plant, is taken
from [1] where the overnight cost of a Slovack FBC plant, fuelled by
brown coal and biomass, is shown: 2762 $2008/kW = 2357 $2000/kW.
The cost is assumed to decrease until 2030 as much as assumed in
ETM2006 (16%) and then remain unchanged over the long term
(1980 $/kW).
Lead time 4 years [1] (corresponding to a 16% capital cost increase, in line with
9
investment cost presented in [1])
O&M cost The operation and maintenance costs are taken as equal as that of
IGCC power plant since they are quite close to data in [1]. The same
approach has been used both in ETM2012 and TIAM.
Capacity factor Is changed from 0.9 to 0.85 in line with [1].
Efficiency The efficiency value in 2010 is taken as larger as that of the Czech
FBC plant (42%), which is in line with the forecasted efficiency of a
new plant commissioned in Poland [3]. Then the efficiency values
are assumed to evolve with the rate used in ETM2012 (48% from
2030).
Life Unchanged (30 years), in line with TIAM.
4. OIL FIRED POWER PLANTS
Technology GENERIC DISTRIBUTED GENERATION FOR BASE AND PEAK
LOAD
Diesel cycle engine-generator power system.
Acronym EOILGBL105 and EOILGPL105
Investment cost The INV_COST can be treated as investment cost rather than
overnight cost.
The same cost data are used in ETM and TIAM. The literature
source is likely to be a DOE document (see Appendix C of [16])
where the cost of the peak load technology is said to be lower
compared to that of the base load.
The costs are all kept unchanged.
Lead time No lead time is used.
O&M cost The cost of the peak load technology is higher than that of the base
load. The costs are kept unchanged.
Capacity factor The Capacity factor is assumed to be the same (90%).
Efficiency The efficiency of the peak load technology is higher than that of the
base load.
Life The life of the peak technology is set shorter (20 years) than that of
the base load (30 years).
Notes Such differentiation seems to be useful only in case the load curve is
modeled.
10
In past ETM version the oil-fueled power plant option was
considered as well. After 2006 it was not included any more whereas
in TIAM it is still part of the technology fleet (EOILSTE105).
Nevertheless, such omission in ETM seems to be reasonable since no
more oil-fuelled power plants are likely to be commissioned.
5. GAS & OIL FIRED POWER PLANTS
Technology GAS/OIL TURBINE
Conventional turbine fuelled by natural gas or, possibly, by oil (i.e.
diesel oil distillates).
Acronym EGOITUR105
Investment cost In the 2012 ETM version the investment cost of EGOITUR105 is
likely to have been drawn from [1] where only one gas turbine is
included in the gas-fired power plant list. This is installed in
Germany and the investment cost (@5% discount rate) is 582
$2008/kW = 457 $2000/kW. The cost of EGOITUR105 is kept
unchanged even if the discount rate in ETM is set at 10% and the
correct investment cost should be 650 $2008/kW = 513 $2000/kW.
The older data (ETM 2006) refers to an American combustion
turbine whose cost is reported in [2] (page 39, 460 $2003/kW = 420
$2000/kW)
Lead time No lead time is considered, being it quite short (2 years) if compared
to the time period length; the INV_COST value is the investment
cost indeed.
O&M cost The O&M cost is taken from [1] and discounted to 2000: 5.38
$2008/MWh = 4.25 $2000/MWh. This value is quite similar to the
―advanced‖ technology in TIAM (EGOITUA105).
Capacity factor Unchanged (85%).
Efficiency In keeping with [1] (38%).
Life 30 years, unchanged.
Notes In TIAM only an advanced Gas/oil turbine is considered whose
investment cost is quite lower than that of EGOITUR105 (325
$/kW).
Technology GAS/OIL CCGT
The fuel is natural gas or diesel oil distillates that is burned in the gas
11
turbine. The heat derived from combustion produces water steam
that is directed to the steam turbine cycle to produce further
electricity.
Acronym EGOICCY105
Investment cost Similarly to the previous technology, the investment cost is likely to
have been drawn from [1]; it refers to an American CCGT power
plant, whose investment cost (@5% discount rate) is 1039 $2008/kW
= 820 $2000/kW. Coherently with the discount rate used in ETM, the
investment cost calculated @10% should be considered: 1113
$2008/kW = 878 $2000/kW.
Lead time No lead time is considered, being it quite short (2 years) if compared
to the time period length; thus the INV_COST value is an investment
cost indeed.
O&M cost The O&M cost is taken from [1] and discounted to year 2000: 3.61
$2008/MWh = 2.85 $2000/MWh. This value is quite similar to the
―advanced‖ technology in TIAM (EGOICCA105).
Capacity factor Unchanged (90%).
Efficiency In keeping with [1] (54%).
Life 30 years, no changes.
Notes Similarly to the previous technology, in TIAM only the advanced
one is considered. The investment cost is quite lower than
EGOICCY105 (600 $/kW)
6. NATURAL GAS-FIRED POWER PLANTS
Technology NATURAL GAS COMBINED CYCLE (NGCC)
The natural gas burns in the gas turbine and the heat produced
passes through a heat recovery steam generator where it produces
steam that drives a turbine. Power is produced from both the gas and
steam turbine-generators.
Acronym EGASCCY105
Investment cost In the oldest ETM versions (until 2006), the investment cost is likely
to have been taken from [4] where a cost range of 600 - 750
$2005/kWh is assumed, corresponding to ~500$2000/kWh (@3%) for
the conventional NGCC, ~600 $2000/kWh (@3%) for the advanced
one.
In the lasted ETM version the conventional technology is no more
considered and the cost of the advanced one is set to 780 $/kW in
12
2003 and 750 $/kW in 2010 [10]. As stated in [10] the gas turbine is
no more included because it’s accounted as negligible in the context
of this model.
According to the more recent literature, the overnight cost of a
NGCC is estimated to be ~900 $2008/kWh as stated in [3] and [1]. In
the last, the overnight cost of the American gas-fired CCGT is 969
$2008/kWh. Thus the INV_COST is set to 880 $2000/kW in 2010,
which is derived from the investment cost at 10% discount rate (1113
$2008/kWh [1]) deflated to year 2000 at 3% inflation rate.
The costs are thought to decrease at the same rate of that assumed in
the previous model version.
Lead time Being the lead time quite short compared to the model time periods,
the INV_COST is the investment cost and the lead time is not
explicitly modelled.
O&M cost The operation and maintenance (fix + variable) costs of an American
NGCC reported in [2] are 3 $2000/kWh (3.3 $2003/kWh @3%, AF =
0.9). In the lasted version of the same study [1], the O&M of an
analogous power plant is 2.85 $2000/kWh (3.61 $2008/kWh @3%). In
the new version of the model the following values are used: 20 $/kW
(fix O&M) and 0.65 $/MWh (= 0.18 $/GJ) (variable O&M) so that
assuming an AF = 90%, the overall O&M costs are ~3 $2000/kWh.
They are set fixed over the entire time horizon.
Capacity factor Unchanged (90%).
Efficiency Unchanged (54%), in line with the American power plant of [1],
more conservative of the hypothesis of [3] where a 57% efficiency is
assumed.
Life Unchanged (30 years) as stated in [2] and [1]. The same assumption
is used in TIAM.
Notes This technology (EGASCCY105) is not considered in TIAM where
only the conventional technology is modeled whose acronym,
EGASSTE105, is the same of the gas turbine of the old ETM
versions. The conventional technology is more expensive (950
$2000/kWh) having the same costs of the CHP technology in ETM.
Technology NATURAL GAS COMBINED CYCLE (NGCC) WITH CO2
REMOVAL FROM FLUE GAS
With post-combustion processes, CO2 is captures al low pressure
from flue gas that generally has a co2 content of 2% to 25%. The
challenge is to recover co2 form the flue gas economically. The
separated gas has to be compressed before transportation. [4]

Acronym EZCCGT110
Investment cost The overnight cost of the ―base‖ technology (NGCC without CCS)
has been increased accordingly to the cost increase estimated by IEA
[3] (+61% in 2010, 47% in 2050).
Moreover the year of technology deployment has been changed from
2010 to 2020 since it is actually not yet deployed worldwide.
In TIAM a less optimistic cost decreased is guessed, reaching 800
$2000/kW already in 2030.
Lead time Not declared, as for the ―base‖ technology.
O&M cost Similarly to the overnight costs, the O&M costs of the ―base‖
technology have been increased by 63% in 2010 and 43% in 2050 as
stated in [3]. Higher costs are assumed in TIAM.
Capacity factor Decreased from 90% to 85%, in line with the ―base‖ technology and
TIAM assumptions.
Efficiency The same assumptions of [3] have been used, namely 36% in 2010
raised to 44% in 2050. In the previous ETM version the efficiency
was higher both in 2010 (50%) and in 2050 (65%). The same values
are taken in TIAM.
Life Unchanged (30 years).
Notes In TIAM the Oxyfueling applied to NGCC (EZCCGO120) is also
considered. It’s recommended to add this technology in ETM as
weel.
Technology SOLID OXIDE FUEL CELL (SOGC)
Fuel cells use an electrochemical process which releases the energy
stored in a natural gas or hydrogen fuel to create electricity. Heat is a
by-product. Among the four types of fuel cells, the most promising
for CHP may be the SOFC. Nevertheless, at present in ETM they are
modeled as only electricity generating technology.
Acronym EGASFCE105
Investment cost The investment cost is set to 1800$2000/kW in 2010 in all model
versions. This value is in line with the cost of a 10MW American
plant [2] (2127 $2003/kW = 1815 $2000/kW @2%). The updated value
is 5000 $2000/kW (in 2008), corresponding to the investment cost
@10% discount rate reported in [1] and in line with the cost in
TIAM (6000 $2000/kW). The rate of cost decrease is chosen so that
the investment cost in 2050 is 3000$2008/kW (2368 $2000/kW) as
14
stated in [3].
Lead time The lead time estimated by [1] is 2-3 years so it is not explicitly
modelled in ETM and the INV_COST is the real investment cost.
O&M cost In ETM the fixed O&M costs in 2008 is set to 12 $2000/kW and the
variable costs to 3 $2000/MWh (1 $2000/GJ) leading to 5.12 $/kWh
overall O&M costs. The overall O&M costs reported in both [1] and
[3] are ~30 $2000/kWh (in line with TIAM) therefore the updated
costs, taken from [3], are: 5 $2000/kW and 32 $2000/MWh (8.8
$2000/GJ).
Capacity factor Is changed from 0.9 to 0.85, according to [1].
Efficiency In ETM this technology is thought to produce only electricity so the
efficiency is set to 50% which is the most optimistic value reported
in [3]. It is kept unchanged over the time horizon, in line with TIAM
assumptions.
Life Unchanged (30 years, as in [1])
Technology SOLID OXIDE FUEL CELL (SOGC) WITH CO2 REMOVAL
Acronym EZSOFGAS20
Investment cost The overnight cost of the ―base‖ technology (SOGC without CCS)
has been arbitrarily increased by 40% since no information has been
found about the costs of this technology.
Moreover the year of technology deployment has been changed from
2020 to 2030.
In TIAM the investment cost is set to 1600 $2000/kW, in line with the
old value in ETM.
Lead time Not declared, as for the ―base‖ technology.
O&M cost Similarly to the overnight costs, the O&M costs of the ―base‖
technology have been increased by 40%.
Capacity factor 85%, in line with the ―base‖ technology.
Efficiency Unchanged due to the lack of information.
Life Unchanged (15 years) as in TIAM as well.
Notes Due to the lack of information the same technology but fuelled by
coal (EZSOFCOA30), accounted in TIAM as well, has been
temporarily removed. A further literature review of both
15
technologies is recommended.
7. NUCLEAR POWER PLANTS
Technology FISSION POWER PLANTS
Fission is a reaction when the nucleus of an atom, having
captured a neutron, splits into two or more nuclei, and in so
doing, releases a significant amount of energy as well as more
neutrons. These neutrons then go on to split more nuclei and a
chain reaction takes place. (IEA)
Acronym ENFCNPPLWR – LWR reactor
ENFCNPPFAR – FR (burner) reactor
ENFCNPPABR – ABR reactor
ENFCNPPATR – ADS reactor (TRU burning)
ENFCNPPAMA – ADS reactor (MA burning)
Investment cost The cost of fission power plants have been updated during WP11.
The differences between the present and previous ETM model
versions and TIAM are reported below. For further details please
see [11][11].
Differently from before, the following data refer to the overnight
costs of European power plants instead of American ones. Specific
regional cost multipliers are therefore set for nuclear sector in the
―SubRes_Trans‖ template.
ENFCNPPLWR – 3710 $2000/kW
ENFCNPPFAR – 3710 $2000/kW
ENFCNPPABR – 2600 $2000/kW
ENFCNPPATR – 2860 $2000/kW
ENFCNPPAMA – 2860 $2000/kW
In 2012 ETM model version, two fission technologies were included
namely, the advanced light water reactors (ENUCLWR110) and
advanced nuclear pebble bed modular reactors (ENUCPBM130)
both having costs quite lower than that just listed. In TIAM even
more cheap technologies are considered.
Lead time So far no lead time is accounted. A five year lead time is
recommended.
O&M cost Due to the lack of information, the O&M costs are not distinguished
in fixed and variable.
Capacity factor 0.8-0.85

Efficiency for more details see 0
Life 50 years
Notes The costs of nuclear technologies in ETM are higher than that
assumed in TIAM. This could lead to low shares of nuclear
electricity in ETM scenarios compared to TIAM’s ones.
Technology Fusion power plants
Fusion is a process where nuclei collide and join together to form a
heavier atom, usually deuterium and tritium. When this happens a
considerable amount of energy gets released at extremely high
temperatures: nearly 150 million degrees Celsius. At extreme
temperatures, electrons are separated from nuclei and a gas becomes
a plasma—a hot, electrically charged gas. (IEA)
Acronym ENUCFUB150 (base) and ENUCFUA170 (advanced)
Investment cost The costs are derived from PPCS study [17] and refer to the
overnight costs of a base technology, model C like, available from
2050, and an advanced technology, model D like, available from
2070.
Differently from ETM, in TIAM the fusion technology is available
from 2008 and its cost is 3000 $2000/kW over the entire time horizon
which is also quite lower than the cost of the ETM base technology
(3940 $2000/kW) and quite close to the advance one (2820 $2000/kW).
In the ETM model versions before 2006, the same assumptions of
TIAM were used.
Lead time No lead time is declared in the present model version. A 5 years lead
time is suggested.
O&M cost The fix O&M costs are lower in ETM than that used in TIAM while
the variable are quite higher. These choices affect the merit order
dispatch and therefore the capacity share of technologies for
electricity production.
Capacity factor Unchanged (85%)
Efficiency 42% (base technology), 60% (advanced technology); in TIAM the
efficiency is lower (32%)
Life Unchanged (40 years)

8. BIOMASS POWER SYSTEMS
Technology DIRECT-FIRED BIOMASS
This technology consists of burning the biomass in a boiler to
produce high-pressure steam, which is then introduced into a
steam turbine for electricity generation. It is the most used and
proved commercial biomass electricity generation option. [12]
Biomass can be burned in a FBC or IGCC power plants: in the
second case the synthesis gas is cleaned and then fired in a gas
turbine to produce further energy.
Acronym EBIOSLC105 – Solid biomass direct combustion (centralized)
EBIOSLCD05 – Solid biomass direct combustion (decentralized)
EBIOCRC105 – Crop direct combustion
Investment cost In principle the two first technology should differ only in the kind of
commodity produced (centralized and decentralized electricity).
However in the present model version they both produce centralized
electricity (to be correct).
On the other hand the last differs from the others because of the
input commodity (crop instead of solid biomass).
That is why the investment costs have been thought to be the same
for all technologies, namely 2200 $2000/kW. In TIAM the same
technologies are modeled but the investment cost is lower (1700
$2000/kW).
In the new ETM version, the same assumption of ETP is used,
namely 2500 $2008/kW (2056 $2000/kW) [3]. This cost, which refers
to a generic biomass steam turbine, is quite close to the cost
estimation of a IGCC power plant (2400 $2008/kW). The investment
cost decreases at the rate assumed in [3].
Lead time The same lead time of an IGCC power plant is assumed (4 years).
O&M cost The O&M cost are kept unchanged being perfectly in line with the
assumption in [3].
Capacity factor Unchanged (90%)
Efficiency Unchanged (25%, [12])
Life Unchanged (30 years), in line with TIAM as well.
Technology BIOMASS GASIFICATION
Biomass gasification is the process through which solid biomass
18
material is subjected to partial combustion in the presence of a
limited supply of air. The ultimate product is a combustible gas
mixture known as ―producer gas‖. There are three main types of
gasifiers – down draft, updraft and cross draft. Other kinds of
gasification technology include fluidized bed gasifiers and
pyrolyzers. [13]
Acronym EBIOSLG105 - Solid biomass gasification (centralized)
EBIOSLGD05 - Solid biomass gasification (decentralized)
EBIOSLGD05 - Crop gasification
Investment cost The distinction among technologies is the same as before. Again, the
investment cost is thought to be the same for all over the entire time
horizon.
In the older ETM version, these technologies are thought to became
competitive with the direct combustion technology in 2020 when the
overnight cost falls at the same level (2200 $2000/kW) .
In the new version of the model the cost of the biomass gasification
technology is set 1.5 times higher than that of the direct-fired
biomass, as reported in [13]. The resulting cost (~3000 $2000/kW) is
in line with the overnight cost of the American solid-biomass fired
power plant quoted in [1].
Lead time 4 years, as for a IGCC power plant.
O&M cost The fix O&M cost are set to 50 $/kW over the entire horizon while
the variable costs are kept unchanged.
Capacity factor Changed in 0.9 over the entire horizon.
Efficiency Unchanged (35%)
Life Unchanged (25 years, in line with [13])
Technology BIOGAS FROM MUNICIPAL WASTE
Municipal solid waste contains significant portions of organic
materials that produce a variety of gaseous products when
dumped, compacted, and covered in landfills. Anaerobic bacteria
thrive in the oxygen-free environment, resulting in the
decomposition of the organic materials and the production of
primarily carbon dioxide and methane. Landfill gas energy
facilities capture the methane and combust it for energy. [13]
Acronym EBIOGAW105
Investment cost In the past ETM version this technology was the more expensive
19
among biomass-fired power plant. On the contrary in TIAM the
incineration of municipal waste does have the higher investment
cost.
In the updated version of ETM, the cost of this technology is derived
by scaling the cost of direct-fired biomass according to the cost
difference stated in [13].
Lead time No lead time is considered as in case of natural gas-fired power
plants.
O&M cost Being no further information about O&M costs available, no
changes are made.
Capacity factor Changed in 0.85, according to TIAM.
Efficiency Unchanged (35.7%)
Life Unchanged (20 years, in line with [13])
Technology INCINERATION OF MUNICIPAL WASTE
Acronym EBMUINC105
Investment cost Being the fluidized bed combustion the most usual technology to
burn municipal waste, the same investment cost is assumed in the
updated version (2357 $2000/kW). This is quite lower than the costs
assumed in the past in ETM (4400 $2000/kW) and in TIAM (3500
$2000/kW) which are both undocumented.
Lead time A 4 year lead time is assumed similarly to the case of a coal-fires
FBC technology.
O&M cost Being no further information about O&M costs available, no changes
are made.
Capacity factor Changed in 0.85, similarly to the previous technology.
Efficiency Unchanged (30.27%)
Life Unchanged (30 years)
9. SOLAR POWER SYSTEMS
Technology SOLAR PHOTOVOLTAIC
Solar Photovoltaic (SPV) systems utilize semiconductor-based
materials which directly convert solar energy into electricity. These
20
semiconductors, called solar cells, produce an electrical charge when
exposed to sunlight. Solar cells are assembled together to produce
solar modules. A group of solar modules connected together to
produce the desired power is called a solar array.[13]
Acronym ESOLPVC105 – Solar photovoltaic centralized
ESOLPVD105 - Solar photovoltaic decentralized
ESOLPVD205 - Solar photovoltaic decentralized
Investment cost The investment costs over the entire time horizon are in line with the
upper level of the cost range proposed in [3] and with the cost of the
American photovoltaic system cited in [1], so they are kept
unchanged. Similar assumptions on the base year costs are used in
TIAM; however the cost decrease due to the technological learning
is more optimistic than that assumed in ETM.
The investment costs in 2010, in line with data in [1], are added in
the new ETM version in order to have a smother cost decrease.
In TIAM a single decentralized technology is modeled. At present
it’s not clear why two decentralized technologies are instead
considered in ETM, having them quite similar technical and
economical features.
Lead time No lead time.
O&M cost They are kept unchanged, being in line with ETP assumptions.
Capacity factor Unchanged, function of seasons and day and night.
Efficiency Unchanged, 100%.
Life Unchanged (~30 years).
Notes In TIAM a number of photovoltaic technologies are modeled but a
capacity upper bound of 0 is associated to all of them, as it was in
ETM before UKAEA revision (2008).
Technology SOLAR THERMAL
Solar thermal power generation technologies comprise several
technically viable options for concentrating and collecting solar
energy in densities sufficient to power a heat engine. These include
Parabolic Dish collectors, Parabolic Trough collectors, and Central
Receivers.
Acronym ESOLTHC105
Investment cost The investment cost is not changed being it in line with the
21
estimation in ETP (lower bound). The cost decrease is less optimistic
than that of [3]. The costs assumed in TIAM are in line with ETM
assumptions.
Lead time No lead time.
O&M cost They are kept unchanged, being in line with ETP assumptions. This
value is missing in the TIAM’s template.

10. WIND POWER SYSTEMS
Technology ONSHORE WIND TURBINES
A wind power generator converts the kinetic energy of the wind into
electric power through rotor blades connected to a generator. [13]
The on-shore wind turbine are placed in the mainland.
Acronym EWINONC105, EWINONC205, EWINONC305 – centralized
EWINOND305 – decentralized
Investment cost The economic data are the same for all technologies. They only
differ in the seasonal CF and the kind of electricity produced. The
number of technologies has been reduced by UKAEA being most of
them redundant. The wind sector in TIAM looks as the old version in
ETM.
In the new ETM version the investment cost has been increased up to
the lower side of the cost range in [3] and the same cost decrease of
ETP is assumed.
Lead time No lead time is considered.
O&M cost The fix O&M cost is increased according to the value in [3] (~ 40
$2000/kW) that is quite close to the value used in TIAM (35
$2000/kW).

Technology LARGE HYDROELECTRIC POWER- DAM
Acronym EHYDDAM205
Investment cost The investment cost is not changed being it in line with the
assumption in ETP [3] (2000 $2000/kW). In TIAM the investment
cost is larger (2500 $2000/kW).
Lead time 10 years, in line with TIAM
O&M cost Unchanged being in line with the ETP assumption (33 $2000/kW)

Lead time No lead time is accounted.
O&M cost Both the fix and variable costs are changed to get closer to ETP data
(~50 $2000/kW) [3].
Capacity factor Unchanged (50%) – it includes the unavailability due to water
scarcity because of dry seasons.
Efficiency Unchanged
Life Unchanged (45 years). The 200 year long life considered in TIAM
seems too much optimistic.
12. GEOTHERMAL POWER SYSTEMS
Technology FLASHED STEAM POWER PLANT
Flash steam plants are the most common type of geothermal power
generation plants in operation today. Fluid at temperatures greater
than 360°F (182°C) is pumped under high pressure into a tank at the
surface held at a much lower pressure, causing some of the fluid to
rapidly vaporize, or "flash." The vapor then drives a turbine, which
drives a generator. If any liquid remains in the tank, it can be flashed
again in a second tank to extract even more energy. [18]
Acronym EGEOFLS105
Investment cost In the previous model versions the acronym was the same of that of
TIAM and the investment cost was quite similar to that assumed in
TIAM as well (1750 $2000/kW). In the more recent model version the
acronym was changed and the investment cost clearly decreased. The
new value of the investment cost has been taken from [3] and
corresponds to the lower bound of the range (1900 $2000/kW). The
same cost decrease of [3] has been used as well (while in the
previous version the investment cost was kept constant over the time
horizon).
Lead time No lead time is considered.
O&M cost They are increased according to the updated value in [3] (180
$2000/kW). The costs used in TIAM seem to be too low compared to
the current literature (35 $2000/kW).

Capacity factor 90% as in TIAM
Efficiency Increased to 10% as in the previous model versions.
Life 30 years, unchanged, in line with [13]
Technology BINARY CYCLE POWER PLANT
Binary cycle geothermal power generation plants differ from Dry
Steam and Flash Steam systems in that the water or steam from the
geothermal reservoir never comes in contact with the
turbine/generator units. Low to moderately heated (below 400°F)
geothermal fluid and a secondary (hence, "binary") fluid with a
much lower boiling point that water pass through a heat exchanger.
Heat from the geothermal fluid causes the secondary fluid to flash to
vapour, which then drives the turbines and subsequently, the
generators. [18]
Acronym EGEOBNY105
Investment cost In the previous model versions the acronym was the same of that of
TIAM. The investment cost has been kept unchanged so that this
technology is an intermediate option as far as the economics of
geothermal power plants. The same cost estimation is given in TIAM
as well. The same cost decrease of [3] has been used (while in the
previous version the investment cost was kept constant over the time
horizon).
Lead time No lead time is considered.
O&M cost They are increased according to the updated value in [3] (180
$2000/kW). The costs used in TIAM seems to be too low compared to
the current literature (50 $2000/kW).
Capacity factor 0.9 as in TIAM
Efficiency Increased to 10% as in the previous model versions. The higher
value in TIAM (100%) is probably due to different resource
estimation but this point should be further investigated.
Life 30 years, unchanged, in line with [13]
Technology BINARY-HIGH CYCLE POWER PLANT
This technology differs from the previous because of the depth
where the geothermal energy is collected.
25
Acronym EGEOBNH105
Investment cost In the previous model versions the acronym was the same of that of
TIAM and the investment cost was quite similar to that assumed in
TIAM as well. In the more recent model version the acronym was
changed and the investment cost clearly decreased. The new value of
the investment cost has been taken from [3] and corresponds to the
upper bound of the range (4400 $2000/kW). The same cost decrease of
[3] has been used as well (while in the previous version the
investment cost was kept constant over the time horizon).
Lead time No lead time is considered.
O&M cost They are increased according to the updated value in [3] (180
$2000/kW). The costs used in TIAM seem to be too much high at the
base year while too low in 2050 compared to the current literature.
Capacity factor 0.9 as in TIAM
Efficiency Increased to 10% as in the previous model versions. The higher
value in TIAM (100%) is probably due to different resource
estimation but this point should be further investigated.

13. MARINE POWER SYSTEMS
Technology OFFSHORE WAVE
Wave power generation is based on the exploitation of the wind-
driven wave energy. [15]
Acronym EMARWAV110
Investment cost The investment cost has been taken from the UK study [14] about
the electricity production from ocean energy. Here the technology is
thought to enter the energy market in 2020. The cost is in line with
the upper bound of the cost range presented in [3] so it’s not
changed. On the other hand, the start year is changed from 2010 to
2020.
Lead time No lead time is accounted.
O&M cost The O&M costs are not changed because they are in line with ETP
[3] and IEA [15] estimation.

Efficiency Unchanged
Life Unchanged (20 years), a bit conservative compared to [15].
Notes This technology has been recently included in the model. It’s not
accounted in TIAM.
Technology TIDAL STREAM
Tidal power is based on two technologies, namely tidal barrage
power and tidal stream power (i.e. marine currents). Tidal barrage
power is a relatively well known technology based upon capturing
seawater with a barrage when the tide is high, then letting the water
flow through hydro-turbines when tidal is low. Tidal stream power
can be considered as a technology under demonstration. [15]
Acronym EMARTDL110
Investment cost The investment cost has been taken from the UK study [14] about
the electricity production from ocean energy. Here the technology is
thought to enter the energy market in 2020. The cost is in line with
the lower bound of the cost range presented in [3] so it’s not
changed. On the other hand, the start year is changed from 2010 to
2020.
Lead time No lead time is accounted.
O&M cost The O&M costs is increased according to IEA [15] estimation.

Notes This technology has been recently included in the model. It’s not
accounted in TIAM.

14. Conclusions.
The model of the power generation sector has been updated according to the most recent
technical literature. A new approach has been proposed, namely to include in the
―Subres_NewTechs‖ template technologies already existing or to be built in the US, while
deriving the cost data or availability factors in other world region by multiplying the
American data by region-specific multiplier.
Moreover a detailed comparison of ETM and TIAM assumptions about the technical and
economical features of the electricity generating technologies has been carried out. The high
number of common technologies together with similarities in naming conventions (see
Annexe 1,Table 3) highlights the common background of the two models.
It was found that ETM is more detailed as far as the nuclear sector being the nuclear fuel
cycle included and the results of the most recent studies about of fusion power plants taken
into account. In TIAM one fusion technology is considered as well, but having the same
features of the old fusion technology modeled in ETM. On the other hand, in TIAM a wider
range of CCS technologies is included being the biomass-fuelled power plants equipped with
CCS are also considered.
The comparison also showed that most of the economic features of the electricity generating
technologies of both models and in some cases the technical features as well, are outdated.
The differences between ETM and TIAM in the technologies’ modelling will probably lead
to different scenario results but the documentation about such differences (see Annexe 2 [to
be added]) will help in detecting the main reasons of possible diverging results. Nevertheless,
together with this, it’s strongly recommended to check the activation of boundaries on
capacity deployment or resource exploitation in both models because of its great impact on
the resulting technology mix.
Finally, the update of the heating producing technologies is recommended for future model
improvement.
