Key Operational Challenges

Availability of coal-fired power stations has been further deteriorating in comparison to assumptions in MYPD 3 application where assumed

average EAF of 82%

Availability further impacted with Duvha boiler and Majuba silo incidents which were not assumed in application

Delay in generation new build in comparison to assumptions in MYPD 3

Requirement for space to maintain Generation units

Require increase in tariffs to costs of further supply options (high OCGTs and STPPP)

to assist in minimising the impact of further load shedding

Context of Selective Reopener of MYPD 3 Application

5

Key Financial Challenges

Funding of OCGT and STPPP Had to borrow to run OCGTs in 2014 and 2015. This amount will be requested for recovery through the RCA

process.

Eskoms cash-flow and liquidity situation cannot allow this to continue

Equity - Unlikely that further equity injection is forthcoming from Government in the short term

Debt - Limits to further significant borrowings are being reached with current credit ratings and negative outlook. Access and costs to

borrowings becoming more challenging

Financial and liquidity challenges where ROA less than cost of capital results in deterioration of balance sheet

Expansion programme funded from debt substantially on a weakened balance sheet

Require increase in tariffs to costs of further supply options (high OCGTs & STPPP)

to assist in minimising the impact of further load shedding

Eskom applying for in selective reopener which will add 10% to the already approved 12,69% for 2015/16

Price decision

MYPD3 original decision of 8% price increase

RCA for MYPD2

Price adjusted for prudent costs and revenue variances through the RCA for MYPD2 which resulted in the awarding of another 4,69%price increase on top of the 8%, equating to 12,69% which has already been approved by Nersa

Selective reopener

Eskom is applying for the recovery of efficient costs relating to OCGTs and STPPP for the next 3 years. Eskom cannot wait for an RCA process to recover these costs due to the financial challenges facing the organisation.

This expenditure will contribute towards Eskom creating space to do necessary maintenance whilst mitigating the impacts of future load shedding.

Requires an adjustment 10% linked to the extraordinary costs to limit load shedding.

If National Treasury gazettes increase in environmental levy by 2c/kWh,

would need to be recovered by Eskom through a further price increase of 2,5%

Energy assumed to be delivered by each coal unit (assume at 75% EAF)

is approximately 4500GWhr per unit per year

This energy had to be replaced by other supply sources

Challenge with sufficient capacity : Status of Eskoms existing generation fleet

The underlying cause of the deterioration in the fleets performance is the lack of sufficient capacity,

aggravated by the onset of age and usage related equipment failures.

About 80% of the existing fleets capacity is now in that period where they require major

equipment replacements in order to restore the plants economic life.

Deferring this work in the recent past is a major cause of the escalation in plant breakdowns.

The first contributor to the capacity shortage is the delay of new capacity.

Decision to build Medupi (and other stations) was needed by, not later than, 1999 to meet

increasing demand by 2007.

Decision only made in late 2004; approval for 1st new base load station made in December 2005

(revised in December 2006 to become Medupi) => needed capacity not available in time.

This was exacerbated by delays in the commissioning of both Medupi and Kusile.

The second contributor is the deteriorating plant performance of existing plant.

Over the past 10 years, but particularly since the 2010 World Cup, necessary philosophy

maintenance was delayed in the interests of keeping the lights on.

The above led to the very high load factors and limited the time available for maintenance outages.

This high utilisation of deteriorated plant created the cycle of deteriorating availability.

Despite some improvements due to efficiency and effectiveness of operations and maintenance,

this cycle can only be broken once there are adequate funds and space in which to perform the

required maintenance

Challenge with sufficient capacity : Creating space for maintenance for sustainability

High and increasing reactive maintenance, and the resultant decreasing amount of proactive

maintenance, are the direct result of the constrained system, aggravated by the reduced plant

reliability and also by capital expenditure constraints.

Eskom is convinced that the only way to restore plant reliability is to put emphasis on proactive

maintenance, which includes refurbishment. If this is done, availability should improve, but if outages

continue to be deferred in order to keep the lights on, availability can be expected to deteriorate

further.

It is thus prudent that the OCGTs were, as was expected when they were commissioned, utilised

beyond their normal peaking function, during the 2015 financial year, to improve the supply / demand

balance during the period of plant shortage as NERSA said in December 2007. This contributed to

creating space for maintenance and limiting load shedding, once all other demand and supply side

options had been fully utilised.

Increase in Environmental levy

In Minister Nenes Budget speech(Feb 2015) increased electricity levy from 3.5c/kWh to 5.5c/kWh, to assist in demand management

When the selective reopener application was made, it was assumed that required legislation will be effective in 2015/16 year however did not occur

Eskom can recover the environmental levy costs from its customers to remain revenue neutral and is treated as pass through item

If tariffs are not adjusted then Eskom can include as variance in RCA will be a time lag in recovery. This would further impact liquidity- thus included in

selective reopener.

NOTE

* The price increase in 2015/16 is above the 12,69% already announced, thus the absolute increase is 22,27% excluding change in enironmental levy

** The price increases of 3,24% in 2016/17 and 7,26% in 2017/18 are absolute increases in those years

***The price drop to 3,24% in 2016/17 is due to the adjustment in 2015/16 which increases the base and thus to achieve the original

allowed revenue in 2016/17 requires a lower price increase. The 3,24% and 7.26% assumes a no RCA adjustment which would need to be

included following regulatory processes. `

Key comments from SALGA and NT

SALGA

Will result in further increasing non-payment and electricity theft thus less steep path of price increases

Committed to financial viability and long term sustainability of Eskom

Require time to rework budget and ensure approval process

Unclear of what cost of unserved energy required to assess impact

Further equity should be provided by National Treasury though constraints in national funding

National Treasury

Eskoms weak financial position and resulting downgrade of Eskoms credit rating is recognised

Only option for healthy financial position and minimise load shedding is increasing tariffs

Need immediate adjustments to assist with current liquidity challenges, and begin strengthening towards a

financial sustainability.

Cost of load-shedding is R9 to 15 per kWh.

Only increases for 2015/16 year supported. Further tariff increases once substantial information towards

cost-reflective or long-run marginal cost tariff level is.

Support NERSA in-principle approval of STPPP costs for 2015/16

In-principle support by Government for OCGTs to prevent load-shedding. Must motivate for exact levels

16

Conclusion

Due to operational and financial challenges facing Eskom, allowance by Nersa

for recovery of higher OCGT and STPPP costs is essential to allow Eskom to

continue to utilise these supply options to help mitigate the impact of load

shedding and contributes to space for Generation maintenance

Under the circumstances, still viable to use expensive OCGT (approximately

R2.75 to R3.00/kWhr depending on fuel price) when compared to cost of

unserved energy estimated by National Treasury to be between R9 to

R15/kWhr

Contributes to improvement of industry towards sustainability

Tariff category increases

There are four types of tariff categories:

1. Municipal tariffs

These are all the tariffs in the tariff book available to Municipal customers bulkand other small supply points.

2. Urban tariffs (directly supplied by Eskom)

These tariffs are Businessrate, Megaflex, Miniflex, Nightsave Urban (Large andSmall), Transflex and Public lighting tariffs. The sales on these tariffs are mainlyfor Mining, Industrial, Traction and Commercial customers.

3. Rural tariffs (directly supplied by Eskom)

These tariffs are Ruraflex, Nightsave rural and Landrate. The sales on thesetariffs are mainly for customers taking supplies in rural areas and are mainly foragricultural customers.

4. Residential IBT tariffs (directly supplied by Eskom)

These tariffs are Homelight and Homepower on the NERSA IBT rates. Thesales on these tariffs are for residential customers.
