c) Description of the proposed MSW project to be set up at Kolhapur, Maharashtra

1. To address the issues of MSW in India, in exercise of the powers conferred by

section 3,6 and 25 of the Environment (Protection) Act,1986 (29 of 1986), the

Central Government, Ministry of Environment and Forest made rules to

regulate the management and handing of the MSW, namely MSW

(management and handling ) Rules 2000. Under Schedule II, Section 5

“Processing of Municipal Solid Waste” following is stated.

9

“Municipal Authorities shall adopt suitable technology or combination of such

technologies to make use of waste so as to minimize burden on landfill.

Following criteria should be adopted namely,

ii) Mixed waste containing recoverable resources shall follow the route of

recycling. Incineration with or without energy recovery including pelletisation

can also be used for processing waste in specific cases.

2. Accordingly, in line with the provisions of the MSW Rules 2000, the petitioner is

developing the project based on mass combustion technology for processing

and disposal of the waste with energy recovery.

3. As per the concession agreement executed between the KGEPL and KMC,

KGEPL is responsible for the development of waste processing facility as per the

terms and conditions specified under the concession agreement.

4. The KMC will supply total 180TPD of MSW to KGEPL to process at the MSW

process facility to be set up at Kolhapur. Detailed Techno-Economic Viability

Report (TEV report) of the project is enclosed along with the petition

(Annexure IV submitted with the original petition).

5. The proposed MSW project involves implementation of a mass combustion

technology for waste to energy conversion. The project activity will process

approximately 180 TPD of municipal solid waste and produce renewable

power.

d) Waste Processing Technology selection

1. The petitioner’s choice to select combustion / incineration technology for

the proposed WTE project is governed by careful study of the merits and

demerits of all Waste processing technological options as well as analysis of

the composition of waste from the Kolhapur city and local conditions. The

petitioner prior to signing the Concession Agreement with KMC, undertook,

inter-alia the following activities as part of due diligence to select the

appropriate technology to sustainably process and dispose waste, overcome

the technical, environmental and social challenges of MSW.

2. Keeping in perspective the waste characteristics in Kolhapur, advantages

and disadvantages of waste processing technologies, ground reality of waste

processing and disposal in the city, maturity of technology, the petitioner

10

has selected mass-combustion technology for the proposed MSW project at

Kolhapur.

3. Municipal Solid Waste has to be managed by technology and methods that

enable keeping our cities clean, prevent pollution & protect environment. As

per CPCB report of 2012-13 municipal areas generates approx 1, 33,760

Tons of Waste per day out of which 91,152 TPD is collected and 25,884 TPD

is treated with some technology. The MSW therefore dumped in low lying

urban areas consumes approx 2, 12,752 cubic meter space every day & 776

ha of precious land per year.

4. While selecting the technology options to treat all components of waste,

factors that have been considered include quantity & composition of MSW,

collection, segregation & transportation capabilities of the Kolhapur

Municipal Corporation, conversion technology, estimation of energy,

compost generation, capital & operational costs, financing options including

levy of tipping fees and user charges.

5. Learning from the past experience is essential to identify suitable technology

for processing of Municipal Solid Waste. There are several technologies

currently being advocated for processing of MSW. These technologies can

be classified into two broad categories namely :

Bio – Chemical conversion of biodegradable MSW.

Thermal processing of MSW.

6. Group one covers technologies such as composting & biomethanation,

whereas Group two includes technologies like gasification, pyrolysis,

incineration & mass burning, Refuse Derived Fuel can also be prepared from

combustible MSW.

7. In Indian context the following technologies are indentified for processing of

MSW –

Biomethanation for wet biodegradable wastes.

Conventional microbial windrow/mechanized/vermin composting for wet

biodegradable wastes.

Refuse derive Fuel from dry high calorific value combustible wastes.

Incineration of dry high calorific value combustible wastes.

11

Biomethanation Technology

8. Biomethanation is an anaerobic digestion of organic materials which is

converted into biogas. It is a biological treatment method that can be used

to recover both nutrients & energy contained in biodegradable municipal

solid waste. This technology can be conveniently employed for

biodegradation of segregated organic wet wastes such as waste from

kitchens, canteens, institutions, hotels & slaughter houses & vegetable

markets. This technology is most suitable for small towns and where proper

segregation of MSW is done to segregate biodegradable & degradable

factions.

9. The disadvantages of this technology is as follows –

Segregated waste is required for adoption of biomethanation technology

Land Requirement is more.

Very Low Volume Reduction of waste i.e. 30%-40%.

Degree of Pollution is high.

Degree of Water pollution is high.

Process Water requirement is high.

Recovery of Energy is low.

Pyrolysis Technology

10. Pyrolysis uses heat to break down combustible polymeric materials in the

absence of oxygen, producing a mixture of combustible gases, liquids & solid

residues. The products of pyrolysis process are – (i) a gas mixture; (ii) a liquid

(bio-oil/tar); (iii) a solid residue (carbon black). The proportion &

composition of various fractions depends on a variety of parameters.

11. Following are the shortcoming of Pyrolysis Technology -

Requires dry waste.

O&M cost is high.

Huge land requirement for storage of fuel.

High project cost as pre treatmentequipments of MSW is mandatory.

High O&M cost.

More fuel requirement in rainy season.

High inert content in Indian MSW.

Percentage of rejects to landfill is high.

12

Composting Technology

12. Composting is a process of decomposition of biodegradable fraction of MSW

under aerobic conditions. This technology is used to handle large quantities

of biodegradable wastes using windrow method. The waste is stacked in

heap for a couple of weeks or buried in a pit to decay for 3 to 6 Months to

mechanized processing. Vermi composting technology is based on use of

earthworms after initial pre processing of waste under a shed. Here the

earthworms eat the organic fraction of waste & excrete – the excrete is

collected as vermin cating, sieved & utilized as bio organic fertilizer. This

technology is most suitable for very small towns & villages.

13. The shortcomings of this technology are as follows –

Non operational in monsoon season.

Large space requirement.

Threat to public health in proximity.

Water pollution is more.

Requirement of Water treatment plant.

Degree of pollution is high.

Rejects to landfill is high thus decreasing the life of landfill.

Very low reduction of volume of wastes i.e. 15%- 30%.

Incineration Technology

14. Incineration is the oxidation of the combustible materials contained in the

MSW. Incineration is used a treatment for a very wide range of wastes. This

process can reduce the waste volume up to 90% and the capital cost of this

process is lower than other MSW treatment technologies. This will work out

best in a centralized system.

15. Incineration technology is complete combustion of waste with the recovery

of heat to produce steam that in turn produces power through steam

turbines. Complete combustion optimally involves a two stage

transformation of fuel, in this case solid waste into CO2 & water vapor. The

secondary phase of incineration takes place as the combustible materials

(e.g. paper, plastics, organic materials containing carbon, hydrogen &

oxygen) combine with oxygen to form carbon dioxide & water vapor.

13

16. In mass burn plants the grate system moves the solid waste through the

drying, burning & burnout zones while promoting combustion. This is done

by ensuring that adequate quantities of air enter from below via holes in the

grates. In this process the entire MSW will be converted into energy with

higher efficiency as compared the other technologies.

17. Appropriate Technology means any technology which is acceptable,

affordable & manageable. There are two angles to technology evaluation.

One what the customer or the consumer expects from a technology and the

other is how the manufacturer designs the technology to meet customer

expectations. As this technology is more financially viable than any other

technology, hence the petitioner has selected the same to be adopted for

Kolhapur project.

cost of setting up of processing plants along with the expected quantities of

value added products & by products that can be obtained during process.

e) Waste to Energy Process and Technology Description

The technology supplier, AV & UE Pvt. Ltd., an IBR approved company is an

innovative technology driven Company involved in manufacturing MSW based

boilers, AFBC, CFBC, IGCC Gasifiers, Sulphuric Acid WHRS, Sponge Iron WHRS,

Package Boilers, Pressure Vessels, Heat Exchangers along with auxiliaries & support

equipments& BOP. AVUE is executing 12 MW waste to energy facility at Hyderabad,

Telangana and is scheduled to be commissioned in March 2015.The facility will be

consuming 1000 tons of MSW on daily basis and has a storage capacity of 5000 tons.

AV&UE’s boiler is developed on the existing reverse push reciprocation grate

technology which is capable of combusting the MSW thoroughly without

segregation even with 45% moisture content in the MSW. The MSW could be more

fully burned by Single Segment Reverse Push Stoker system so as to decrease the

heat reduction rate of ash slag. Currently, AV&UE provide services to major players

like Larsen & Tubro, GMR, Babcock Borsing Services, Gujarat State Fertiliser &

Chemicals Ltd., Mono Steel, Aditya Birla, SAIL, AML Steel Ltd. & many more.

REVERSE PUSH RECIPROCATING GRATE TECHNOLOGY

15

The Single Segment Reverse Push Stoker System shall be capable of combusting

municipal waste containing moisture around 40%.

The reciprocating stoker system will consists of a refuse feeder, a reverse acting

stoker with adjustable device of refuse layer, a combustion control system and an

ash discharge system.

This technology is developed based on the existing reverse push reciprocation

grate, and its core is in view of the living MSW features of low heat value and high

moisture. The MSW could be more fully burned by Single Segment Reverse Push

Stoker system so as to decrease the heat reduction rate of ash slag. The primary air

used for supporting burning is preheated by secondary air heater to make the

temperature more than 240 ºC to 250 ºC, so as to make the MSW that enters into

furnace dried, fired and burned at a quick speed. The extra air factor of boiler is

designed to be over 1.6, to maintain sufficient oxygen in boiler and reduce the

production of TEQ. Our boiler, high-temperature secondary air sprays into at a high

speed to make sufficient disturbance of flue gas, prolong the residence in furnace,

so as to improve the combustion condition to ensure the flue gas temperature not

lower than 850 deg. C in furnace and residence over 2 seconds.

In view of the situation that the primary air which is used for supporting burning is

difficult to control, division air chambers is designed, that is in accordance with the

different regional features during MSW burning, the air chamber under the grate is

divided into several relatively independent air chambers, each chamber equipped

with air adjust door. Under certain air pressure, by adjusting the primary air amount

in one or several or all air chambers, the regional or the whole combustion condition

could be improved. The open range of air door and air amount is designed to be

linear ratio, and the combustion condition could be exactly controlled by auto

control system.

THE POWER GENERATION SCHEME

The steam cycle define the transformation of the chemical energy in the fuel to the

mechanical energy at the turbine shaft, through the various thermodynamic processes. The

Cycle is a sequence of thermodynamic processes that is capable of producing the net heat

flow or work when placed between the energy source and an energy sink. Any Cycle needs a

working fluid and steam is viewed as the most favoured working fluid mainly because of its

unique combination of high thermal capacity, high critical temperature, wide availability at

cheaper cost and non-toxic nature. Higher thermal capacity of the working fluid generally

results in smaller equipment for the given power output or heat transfer.

All the steam-based power plants operate under the Rankine Cycle. Simplistically the

Rankine Cycle is described as the combination of the various process like the isentropic

compression of water in the boiler feed water pumps, reversible heat addition to the

working fluid through the liquid, two phase and superheat states, isentropic expansion of

the working medium in the turbine and the constant pressure heat rejection to the

atmosphere through the condenser and the cooling water system. The cycle to be adopted

for this project will be a modified Rankine Cycle with the addition of the Regenerative feed

water heating. To improve the efficiency of the cycle the feed water from the condenser is

heated with the steam extracted from the turbine. Because of the size of the plant there are

limitations in the use of the number of stages for heating the feed water, and for this project

only one stage of heating is done in a deaerator.

High pressure and high temperature cycles arc crucial for increasing the operating efficiency

and the power output from the power Plants. The choice of the level of the pressure and

temperature for the cycle depends on the level of confidence in the plant operators, quality

of the feed water and the water treatment systems available and the cost of the high

pressure/temperature boiler and Turbogenerator systems and the financial benefits

realizable from the power plant by way of the sale of the exportable power.

Thermodynamically, energy recovery from the Rankine Cycle is more dependent on the

steam inlet temperature than the pressure and the higher the inlet steam temperature,

higher the cycle efficiency. However, the practically attainable limits of temperatures are

influenced by the metallurgy of the boiler tubing, piping and the turbine components and

the complexity of the Creep fatigue interaction for the materials at higher temperatures.

19

Temperatures up to 400°C require the use of ordinary carbon steel and beyond 400°C, low

grade alloy steels are employed. Above 500°C, the requirements become stringent and

expensive and above 550°C, the requirements are very stringent and prohibitively expensive.

It is extremely important that the selection of the temperature is done keeping in mind the

nature of the industry, nature of the fuel fired in the boiler, cost of fuel & environmental

considerations. Considerations such as cost, maintainability, provision of adequate safety

margins, the experience of the industry so far and the level of the operating personnel

available in the industry, force us to a selection of a safe operating temperature for the

plants of the subject size and nature. With the boilers fired with MSW / bio-mass fuels

whose nature, composition and-size are difficult to control, it is also important to keep in

mind that the super heater steam temperature response is a little erratic, even with a good

steam temperature control system. This is mainly because of the nature of the fuel and the

difficulty to ensure a correctly metered quantity of fuel flow to the boiler. The nature of fuel,

especially the Chlorine content in the fuel and the corrosive nature dictates the steam

temperatures for the project.

Considering the above, for AVUEPL, it is proposed to install the boiler with outlet steam

parameters of 40 ata and 400°C ± 5°C. The steam inlet to the turbine will be 39 ata and

390°C, with the difference in the pressure and the temperature accounting for the losses in

the steam piping from the boiler to the turbine.

Plant Operation

The Power plant will export a nominal 1.45 MW power on a continuous basis. The power

requirements of the auxiliaries of the Power plant is0.35 MW, and the gross power

generation in the plant will be 1.8 MW to meet with both the exportable power as well as

BOILER & FLUEGAS TREATMENT

21

the in-house requirements. The plant will operate for a minimum of 292 days per year at the

designated capacity.

The feed water management program shall ensure the supply of good quality make up water

to the system. In the proposed power cycle most of the steam supplied to the turbine, about

98% will come back as the condensate from the air cooled condenser and through the feed

water heating systems.

The makeup required will be approximately 4% to 5% of the steam generated in the boiler,

which includes all the losses in the system and the blow down in the boiler. The complete

make up required for the plant operation will be treated water and a reverse osmosis water

treatment plant of adequate capacity will be provided. The make up for the cycle will be

added in the condensate tank of the air cooled condenser and the quantity of makeup will

be controlled by the deaerator level control system.

The feed water temperature at the inlet of the feed water pumps of the boiler will be 105°C,

with the feed water heated in a thermal Deaerator. The temperature of the feed water at

the pump outlet will be around 106°C; the rise in temperature is attributable to the work

done in the pump.

The proposed turbine will be a single extraction cum condensing machine, the extraction

being uncontrolled. The extractions will be at the pressure of 6.535ata and this extraction

quantity is very small and meets only with the requirements of the deaerator and SCAPH.

The steam required for ejector & gland sealing will be at the pressure of about 10.0 ata,

which could be taken through a PRDS station in the plant.

The Power Generation cycle will be provided with the only one Feed water heating system in

the form of a deaerator serving the dual purpose of deaerating the feed water as well as

heating the feed water with the uncontrolled extraction steam at 6.535 ata from the

turbine. The deaerator’s capacity will be 140 TPH and the capacity of the deaerated water

storage tank shall be minimum 46 m3. The Deaerator system will be operating at 1.235 ata

pressure, with the deaerated feed water temperature at 105°C.

The power generation in the turbo generator will be at 11 kV level. The turbo generator will

be operating in parallel with the State Grid. Out of the gross generation of power at the

generator terminals the in-plant power requirements will be met by stepping down the

power in a step-down transformer and the balance of the generated power will be exported

to the Grid. The exportable power will be stepped up and will be connected to the nearby

sub-station of state grid. Adequate space and transformer capacities are available at the

substation, for receiving the exportable quantum of power from the Power plant.

22

The Power plant’s water requirement will be met by drawl from bore wells, within the plant

and also from the nearby river.

The Power plant’s in-house power requirements, including the power requirements of the

auxiliaries of the boiler, auxiliaries of the turbo-generator, the power requirements of the

balance of the plant equipment, the fuel processing plant and including-the losses, works

out to a total of 350 kW.

Description of the Power Generation Scheme

The Power generation scheme proposed envisages a single boiler with all its auxiliary

systems and an extraction cum condensing turbo-generator with all its auxiliary systems and

HV systems for the export of the power to the grid and the remaining balance of plant items

to complete the power plant.

The Scheme envisages 1 x20 TPH capacity steam generator with the outlet steam

parameters of 40 ata and 400°C ± 5°C, with the feed water inlet temperature of 105°C. The

Turbogenreator to be installed will have 1.8 MW capacity with single uncontrolled

extractions. The plant will be designed with all other balance of plant systems like the fuel

handling system, Ash handling system, raw water system, auxiliary cooling water system, air

cooled condenser system, reverse osmosis water treatment system, compressed air system

and HV systems, etc. for its successful operation.

The scheme is configured to optimize, the power generation, with one stage of feed water

heating. The extraction of steam and its usage in the Deaerator for the Feed water heating

improves the efficiency of the plant.

The entire steam generated in the boiler is fed to the single extraction condensing

turbogenerator. The uncontrolled extraction from the turbine at 6.535 ata gives steam

approximately at a temperature of 215°C. This steam is entirely used for heating up the feed

water in the thermal deaerator and for SCAPH. In -addition to this steam, the flash steam

recovered from the boiler blow down tank is also proposed to be used in the deaerator. The

flash steam from the continuous blow down tank, equivalent to 0.237 TPH will be led into

the deaerator for supplementing the steam supplied from the turbine extraction for

deaeration.

The balance of the steam supplied to the turbine, after the extraction, is exhausted at 0.1

ata to the condenser of the power turbine. The condensate from the condensate tank

of the condenser is then pumped to the feed water system by the condensate extraction

23

pumps. In addition to the above quantity, the condensate from the gland steam condenser

and the ejector condensers is added to the feed water system through the condensate tank.

The make up for the system is basically to take care of the -losses in the system. The major

losses in the system are the blow down from the boiler and the vent losses from the various

equipments like the deaerator, gland steam condenser and ejector condenser etc. and the

leakages in the system. The losses in the blow down are about 0.633 TPH and the vent losses

from the various equipments are estimated to be 0.167 TPH. A provision of about 3% is

made for meeting with the leakages in the design of the makeup water system.

The condensate returning to the boiler consists of mainly the condensate from the water

cooled condenser, the condensates from the Gland Steam Condenser and the condensate

from the ejector condensers. All these condensates are collected in the condensate tank and

then pumped to the deaerator for the purpose of deaeration and feed water heating by the

condensate extraction pumps. The makeup water to the system is added to the deaerator.

The makeup is a small quantity and also it is necessary that the make-up is supplied to the

deaerator at a higher pressure for the purpose of atomisation for the effective deaeration.

The makeup water supply to the system is controlled by the level control system of the

deaerator.

PROJECT IMPLEMENTATION SCHEDULE AND WILLINGNESS TO POWER PURCHASE BY

DISCOM

The Project implementation schedule and application made to DISCOM for procurement of

green energy from the proposed MSW plant is attached with the petition in the form of

Annexure IX and Annexure X respectively ( submitted with the original petition).

27

C. Justification for the Submission

In the subsequent Paras, the petitioner respectfully submits before the Hon Commission the

following facts:

a. Statutory provisions under which the petition is being filed before the

Commission.

b. Reason why the Commission has jurisdiction to try, entertain and dispose of the

petition

c. Justification for the proposed technology, capital cost and Tariff

a) Statutory provisions under which the petition is being filed before the

Commission.

1. Section 62(1) of Electricity Act 2003: Section 62(1) of the Electricity Act

mandates the Commission to determine the tariff for supply of electricity by a

generating company (including renewable sources of energy) to a distribution

licensee, transmission of electricity, wheeling of electricity and retail sale of

electricity in accordance with the provision of the Act. The Commission is duly

bound to determine all tariff ( including renewable sources of energy ) as

specified in section 62 (1) of the Act and while doing so the Hon. Commission is

guided by the terms and conditions for tariff determination framed under

Section 61(h) of the Electricity Act . Section 61 (h) of EA 2003 specifies that while

drafting the terms and conditions for tariff determination the Commission

should see the need for promotion of co-generation and generation of electricity

from renewable sources of energy.

2. Clause 8.1 of MERC (terms and conditions for determination of RE tariff)

Regulations 2015 specifies that the Commission shall determine ‘Project specific

tariff’, on case-to-case basis for municipal solid waste based projects. Clause 8.2

of above regulation states that “Determination of project specific tariff for

generation of electricity from such RE sources shall be in accordance with such

terms and conditions as may be stipulated under relevant Orders of the

Commission. Provided that the financial norms specified in Chapter 2, except with

regard to Capital Cost and O&M expenses, shall be the ceiling norms while

determining such project-specific tariff.”

3. Clause 9.2of MERC (terms and conditions for determination of RE tariff)

Regulations 2015 specifies that “A petition for determination of project-specific

tariff shall be accompanied by such fee as may be specified in the applicable

28

Regulationsof the Commission, and shall be accompanied by a) Information in

Forms 1.1, 1.2, 2.1 and 2.2 as the case may be, appended as Annexure-A of these

Regulations; b) a detailed project report outlining technical and operational

details, site specific aspects, premises for capital cost and financing plan, etc. c) A

Statement of all applicable terms and conditions and expected expenditure for

the period for which tariff is to be determined. d) A statement containing details

of any grant, subsidy or incentive received, due or assumed to be due from the

Central Government, and/or State Government, which shall also include the

computation of tariff without consideration of such grant, subsidy or incentive..

e) Details of financial gain through REC or any other mechanism. f) Any other

information that the Commission may require the Petitioner to submit. The

petitioner has annexed the requisite information as specified under (a), (b), (c)

and (d) above with the petition.

4. The National Electricity Policy (NEP) notified by the Government of India also

envisages importance of MSW projects. Clause 5.10.5 of NEP states that “Setting

up of municipal solid waste energy projects in urban areas and recovery of

energy from industrial effluents will also be encouraged with a view to reducing

environmental pollution apart from generating additional energy.”

5. Point 7 in Chapter VII of Integrated Energy Policy issued by Government of India

states that “for grid connected renewables, Regulatory Commissions (RC’s)

should provide feed-in laws to permit renewables to supply electricity to the

grid”.

b) Reasons why the Commission has jurisdiction to try, entertain and dispose of the

petition

1. As far as the urban and industrial waste is concerned, the environmental

problem that is caused in metro cities, both from the collection and disposal

points of view, hardly needs emphasizing. Such urban wastes are not only the

source of bad odor but also cause methane generation, a serious cause of global

warming and consequent environmental degradation. Kolhapur city is no

exception to this.

2. Scarcity of landfill site for MSW dumping is another cause of worry. All the

available landfill sites in big cities have nearly reached their full capacity.

Dumping of untreated waste at these landfill sites is environmental hazard both

on account of methane that is generated, which escape into environment

29

causing ‘Green house effect’ and leachate causing contamination of ground

water resource.

3. In order to provide a sustainable solution to the ever increasing problem of

disposal of waste, especially in the larger cities in Maharashtra, setting MSW to

energy projects is the only effective solution therefore such projects should be

promoted and the promoters should be given incentives to develop such

projects.

4. As stated earlier, the mass-burn combustion technology proposed by the

petitioner has several distinct advantages as i) lowest life cycle cost, ii) needs

less land area , iii) produces more power with less waste iv) causes maximum

volume reduction.

5. It is true that as per the MSW (management and handling) Rules 2000, the

disposal of waste is the primary responsibility of the urban local bodies. These

rules require all local self governments to establish scientific solid waste

processing facilities on or before 31st December 2003. However despite these

rules there has not been any material improvement in MSW management

practices across India. The compliance rate of Indian Municipal Corporations

with the MSW Rule 2000 is very low essentially due to the limited financial and

technical resources with the municipalities. The Hon Appellate Tribunal of

Electricity (ATE) in its recent judgment in appeal No. 197 of 2010 & IA nos. 276 &

277 of 2010 dated 16 September 2011 in the matter of Solapur Bioenergy

Systems Pvt. Ltd., ruled that “the Municipal Corporations would fulfill its

obligation under the MSW 2000 Rules once it has done the simple segregation

for environment point of view, processing and disposal of the municipal waste.

The Municipal Corporation is not required to undertake specified segregation for

making MSW ready as a fuel. There is no obligation of the Municipal Corporation

in absolute term that all waste should be completely processed and utilized to

the full extent”. The ATE further ruled that the Commission should consider the

pre-treatment cost associated with the segregating /screening of the waste

under the capital cost while specifying generation tariff for MSW power

projects.

6. The Commission may also consider the environmental and social importance for

promoting such waste to energy projects and the fact that it generates power

and simultaneously disposes of the MSW in a scientific manner. Hon.

30

Commission may consider the future fuel cost escalations and environmental

externalities associated with conventional power projects while justifying the

higher tariff for the electricity generated from MSW power plants.

c) Justification for the proposed technology, capital cost and Tariff

1. Observations from the National Master Plan (NMP) for development of WTE

projects in India (Assessment of Municipal Solid Waste to Energy Technology)

Technical Memorandum on Waste to Energy Technology, National Master Plan for

Development of Waste to Energy in India under Assessment of Municipal Solid WTE

technologies has made an evaluation of the applicability of the technologies of

biomethanation, gasification/pyrolysis, incineration and land filling as Waste to Energy

options in the global context. The evaluation results are given below.

31

In the analysis presented in the above table, the incineration / combustion technology

scores an overall rating of 67 out of 150 with technical, commercial and environmental

factors.

2. Recommendation under National Master Plan for development of waste to

energy projects

MNRE in the document titled “Technical Memorandum on Waste to Energy Technologies”

has assessed all the available potential technologies for Municipal Solid Waste to Energy

projects on the basis of certain criteria such as system configuration, system auxiliaries,

environmental aspects, resource recovery and commercial aspects. The study underlines the

advantages of the incineration / combustion technology as given below:

Advantages of Mass-Combustion Systems

Mass- combustion systems have larger capacities and higher thermal efficiencies

Mass-combustion systems, as compared to modular systems, generate a higher-

quality steam, allowing for higher revenues per tonne of waste

These facilities can accept refuse that has undergone little pre-processing other than

the removal of oversized items

Mass- combustion avoids many of the refuse handling problems caused by the

extreme heterogeneity and variability of MSW

The net energy conversion can be equal to or better than that for RDF systems, since

minimal energy is used for front-end processing and no burnable material is

removed

Since most of the burning occurs on the grate, less particulate matter is entrained in

the gas stream and air pollution control costs are thus reduced

The units are compact and therefore land requirements are less than for RDF

3. Justification for capital cost, tariff and long term benefits of proposed WTE

technologies.

i. The NMP for development of WTE under technical memorandum on investment and

funding strategies has compared the available technological options in terms of

capital cost; O&M cost, project life etc. The final results as given in the referred

technical memorandum are reproduced below:

32

(Source: Financial analysis of MSW WTE facility under technical memorandum on investment

and funding strategies, page no – Chapter 3-8)

The above cost bench marks are based on year 2002 -03 data. As per above analysis

, for a typical 150 TPD capacity MSW power plant based on RDF based incineration

technology, the capital cost is Rs 14 Cr and O& M cost is around 13.57% of capital

cost. Recently Gujarat Electricity Regulatory Commission approved Rs 14 crore / MW

as capital cost for combustion based Waste-To-Energy (WTE) power project of

Abellon Clean Ahmadabad Limited to process and dispose the Municipal Solid Waste

in case no 1334 of 2013 dated 23 December 2014.

ii. The Petitioner would like to mention that the proposed tariff of Rs 7.44/kWh is a

levellised tariff computed over the useful life of the plant (20 years) and will remain

constant for 20 years after commissioning of the plant.

On the other hand the cost of fossil fuel is going to increase in future as the reserves

of coal and natural gases are depleting at an alarming rate. Similarly, a substantial

part of the fossil fuel is imported from the politically sensitive countries. This will

certainly increase the average power procurement cost of the DISCOMs in the state

in near future.

A table showing break up of cost for Indigenous plant and machinery and imported plant

and machinery - including Basic cost , Excise duty / custom duty , VAT, Insurance,

c) Basis for selecting Tariff parameters

1. The petitioner has studied the tariff related provisions outlined in MERC (terms and

conditions for determination RE tariff) Regulations 2015, National Tariff Policy, and the

RE tariff Regulation notified by CERC as well as the ruling of ATE in case of Appeal No.

197 of 2010 & I.A. nos. 276 & 277 of 2010 dated 16 September 2011.

2. As specified in clause no 8.2 of MERC (terms and conditions for determination RE tariff)

Regulations 2015, the petitioner has adopted Project specific tariff computation

methodology for the proposed MSW to energy project at Kolhapur. Accordingly, a

single-part levellised tariff worked out over the life of the project (20 yrs) based on cost-

plus approach for procurement of electricity from the proposed MSW power plant at

Kolhapur.

3. As specified in the MERC (terms and conditions for determination RE tariff) Regulations

2015, the financial parameter for other RE technologies except the capital cost, and

O&M are considered as ceiling norms for determination of project specific tariff for the

proposed MSW power project at Kolhapur. Particularly, the financial parameters as

Determination of Generic Tariff for Renewable Energy for the second year of the Review

Period from 1 April 2016 to 31 March 2017) dated 4 March 2016 has been considered

for the computation of the project specific tariff.

4. The capital cost and other operating parameters like O&M cost, capacity utilization

factor, Auxiliary consumption are considered as the Detailed Project Report prepared

for the proposed project.

d) The performance/operating and financial components considered for computation of

tariff for electricity generated from MSW power plant:

1. Capacity utilization factor: Considering the availability of MSW from KMC, variation in the

quality of MSW across the seasons, the Capacity utilization factor considered as 65%

during stabilization period (first year) and 80% for remaining period, which seems

reasonable for tariff computation.

2. Capital cost: Capital cost of the project is considered as given in para D (a) above.

3. Debt : Equity ratio: In case of the Debt : Equity ratio the MERC (terms and conditions for

determination RE tariff) Regulations 2015, specifies the same as 70:30. In case of the

change in equity contribution than that of 30% the regulation has following provisions:

If the equity contribution is less than the normative equity of 30% the actual equity

participation will be considered and if the equity contribution is more than that of 30%

then 30% will be considered while determination of tariff and the additional equity over

and above 30% will be considered as debt.

The petitioner has proposed to incur the Debt : Equity ratio as 65:35. However, the

petitioner proposes the Debt : Equity ratio as 70:30 in line with provisions of the MERC

(terms and conditions for determination RE tariff) Regulations 2015 for determination of

tariff for the said project

4. Term of the loan: The loan repayment period of 12 years is considered in line with the

clause 15.1 of the MERC (terms and conditions for determination RE tariff) Regulations

2015.

5. Interest on debt: In the MERC (terms and conditions for determination RE tariff)

Regulations 2015, Hon. Commission had considered interest on long term debt as 300

basis points above the SBI base rate prevailing in the previous year. Accordingly as given in

35

the draft RE tariff order for FY 2016-17, the base rate (9.56%) plus 300 basis point has

been considered as interest rate for tariff determination purpose. Therefore, the

petitioner has considered interest on debt as 12.56% per annum.

6. Working capital and interest on working capital: The petitioner has computed the

working capital in accordance with the MERC (terms and conditions for determination RE

tariff) Regulations 2015 comprising of (a) operation and maintenance cost for one month,

(b) receivables equivalent to 2 months of net energy charges for the sale of electricity

calculated on the normative CUF and (c) Maintenance spares @15% of operation and

maintenance expenses. The MERC RE Regulations 2015 allows interest on working capital

as SBI base rate plus 350 basis points. Accordingly the petitioner has consider interest on

working capital as 13.06 % per annum

7. Return on equity: MERC (terms and conditions for determination RE tariff) Regulations

2015 allows return on equity as base rate of 16% to be grossed up as per applicable tax

rate. The Regulations also provide that rate of Return on Equity shall be computed by

grossing up the base rate with the tax rate equivalent to Minimum Alternate Tax (MAT)

for the first 10 years from COD, and the normal tax rate for the remaining years of Project

life. Accordingly, as per prevailing tax rate, the base rate of 16% has been grossed up with

MAT (@21.34%) for first 10 years and with income tax (@ 34.61%) for remaining 10 years

of plant operation for the project specific tariff computation purpose.

8. Life of plant and machinery:, The petitioner has considered 20 years as the useful life of

the plant and machinery. Same was considered under RE Tariff Regulations 2010 as well

as for biomass and non fossil fuel based cogeneration projects under new RE tariff

regulation 2015.

9. Depreciation of plant and machinery: In line with MERC RE tariff Regulations 2015, the

depreciation is computed at the rate of 5.83% per annum for the first 12 years of Tariff

period and the remaining depreciation amount (up to 90% of capital cost) is spread over

the remaining useful life of the project (8 years).

10. Operation and maintenance expenditure: The clause 8.2 of MERC (terms and conditions

for determination of tariff from renewable sources of energy) Regulations 2015 allows to

consider the actual O&M cost while determining the project specific tariff for the waste to

36

energy project. The actual O&M cost for the proposed project is estimated at 6.6% of the

project cost (Rs 165 lakhs in first year).

Due to the pre-treatment (screening, shredding & segregation of waste) requirement the

O&M cost is slightly higher than the other RE power projects. The petition has considered

the actual O&M expenses of 6.6% of capital cost with an annual escalation of 5.72% per

annum for determination of tariff. Further, the petitioner has considered Rs 100 lakhs as

periodic maintenance cost (included in the O&M cost) in every three years. Considering

the nature of operation the petitioner humbly requests to consider the proposed O&M

costs.

11. Auxiliary consumption: The petition has considered the overall plant auxiliary

consumption of 20% of gross generation for the tariff computation purpose. The

petitioner has furnished 16% as a main plant equipment auxiliary consumption and 4% as

plant lighting, building services & transformer/other equipment losses. The details of

auxiliary consumption are as follows.

12. Income from sale of product: Bottom ash (30 TPD) which will be generated in the process

will be sold in the open market @ Rs 150 / Tonne. Yearly income has been calculated as,

yearly Income = TPD of by product (30 TPD) X rate of by product X capacity utilization

factor considered for the project (65% for first year and 80% for remaining period).

13. Income from tipping fee: As per the concessional agreement, tipping fee for 180 TPD @ Rs

308 /Tonne, without any escalation, has been also considered as income in the account of

project developer. Yearly tipping fee income has been calculated as, yearly Income from

tipping fee = TPD of MSW receive (180 TPD) X tipping fee rate X capacity utilization factor

considered for the project (65% for first year and 80% for remaining period).
