The Public Utilities Commission of Sri Lanka issued a consultation paper on setting electricity tariffs for the period of 2011-2015. The paper presented key issues for public comment, including sales forecasts and allowed losses for transmission and distribution licensees. Distribution licensees filed sales forecasts and loss allowances between 2011-2015 ranging from 11-14.8% losses. The transmission licensee filed purchases from generation and loss allowances of 11% for 2011. The paper proposed allowed revenues for licensees and the provision for energy sold for street lighting. It analyzed government subsidies to the electricity sector and presented a roadmap for tariff restructuring and rebalancing to achieve cost-reflective tariffs by 2015. Finally, the paper outlined proposed electricity tar

5. Consultation Paper on Setting Tariffs for the
Period 2011-2015
1. PREAMBLE
This consultation paper is issued under Section 30 of the Sri Lanka Electricity Act No 20 of 2009 (the
“Act”), for the purpose of allowing consumers and other interested parties to participate in setting the
tariffs in accordance with the cost-reflective methodology approved by the Commission.
In accordance with Section 32(2)(a) of the Act, the Commission, on 26th July 2010, approved a cost-
reflective Methodology for Tariffs and subsequently issued the same to the Transmission Licensee
and all the Distribution Licensees . The Methodology for Tariffs issued to the Licensees is available as
a separate document . The methodology has the following key features:
1
(i) The purchase of generation by the Transmission and Bulk Supply Licensee (the “Single
Buyer”) will be passed-through to the Distribution and Supply Licensees, and thereby to the
end-use customers. The revision period for such approved generation pass-through costs will
be once in six months.
(ii) Tariffs chargeable by the Transmission and Bulk Supply Operations Business of the
Transmission Licensee will be based on multi-year tariff principles, where the Base Allowed
Revenue for the Transmission Licensee will be capped at the same price each year for the
entire Tariff Period (“a fixed revenue cap”), subject to (a) allowances when large transmission
capital investments are commissioned, allowed as and when such events occur, and (b)
annual adjustments to the Base Allowed Revenue on account of inflation and exchange rate
variations.
(iii) Tariffs chargeable by the Distribution and Supply Licensees for the Distribution and Supply
business will be based on multi-year tariff principles, where the Base Allowed Revenue for
each Distribution Licensee will be capped but vary from year to year over the Tariff Period (“a
variable revenue cap”), subject to annual adjustments to the Base Allowed Revenue on
account of inflation and exchange rate variations, and variations of the number of customers
and amount of energy sold.
(iv) The Commission has determined that (a) the first six-month period for the determination of
generation pass-through costs would commence on 1st January 2011, and that (b) the first
Tariff Period for the determination of Transmission Licensee’s and Distribution Licensees’
allowed revenues to be five years commencing on 1st January 2011.
(v) To reflect the variations in the allowed generation pass-through costs in each six-month
interval, and the Transmission and Distribution allowed revenues once in 12-months, the end-
use customer tariffs would be changed once in six months.
(vi) Owing to the limited information available to the Commission to assess the Licensees’ revenue
requirements, the Commission has determined that there will be an extraordinary tariff filing
by the Transmission Licensee and Distribution Licensees on or before 30th June 2011, for the
remaining period of the first Tariff Period (ie 2012-2015), by which time, certified information
including audited statement of accounts for each Licensee should be filed with the Commission
(vii) Owing to the requirement to maintain uniform national tariffs to end-use customers,
irrespective of varying costs of each Distribution Licensee, the Commission requested each
Licensees to file only their revenue requirements. Once the revenue requirements are
reviewed and approved, the Commission has used such Allowed Revenues to develop the
proposed end-use customer tariffs.
The Commission approved and issued the following time table for the setting of tariffs:
Submission of revenue requirements by the Licensees for the first Tariff Period: 9th
September 2010 (completed)
Analysis of revenue requirements, clarifications by Licensees and preparation of the
Commission’s proposals: 14th October 2010 (completed)
Period allowed for Public Consultations: 24rd November to 08th December 2010

7. 3. ALLOWED REVENUES FOR LICENSEES
3.1 SALES FORECAST AND ALLOWED LOSSES
Forecast sales of electricity and the allowed losses in transmission and distribution have an impact on
the investments and operating costs of licensees, and on the pass-through costs of electricity
generation, all of which will impact the end-use customer tariffs.
3.1.1 SALES FORECAST AND LOSSES FILED BY LICENSEES
Sales forecasts, purchases from the Transmission Licensee (TL) and the loss allowances filed by the
Distribution Licensees (DLs) are shown in Table 1. Sales to DLs, purchases from generation and loss
allowances filed by the TL are shown in Table 2.

3.1.2 ADJUSTED SALES FORECAST AND ALLOWED LOSSES
The following corrections were made to the licensee loss allowances:
(a) The Commission reviewed the losses filed for year 2009. The filed sales of CEB DLs was
8441 GWh (including sales to DL5- LECO). On the basis that TL’s losses in year 2009 were 2.7%,
the calculated input to the TL’s network would be 9936 GWh. Therefore, the total CEB licensees’
(TL, and DL1, 2, 3 and 4) network loss for 2009 as a share of input to TL would be 15.0%. With
the addition of power plant auxiliary power requirements and power plant step-up transformer
losses, CEB reported elsewhere, that the total loss was 14.6%, which is significantly lower than
the 15.0% transmission and distribution loss implied in the filed losses. This mismatch was
corrected by reducing the allowed losses of all CEB DLs for 2009.
(b) The Commission observes the even with the above corrections, the total transmission and
distribution network loss of Sri Lanka for year 2009 is estimated to have been 14.2%, which fell
short of the policy target of 13.5% in 2009 established in the National Energy Policy and
Strategies .

8. (c) The uncorrected losses (as filed) for the total transmission and distribution network in 2015 was
14.4%. The corrected losses indicate a total network loss of 13.3% in 2015. A target of 12% of
transmission and distribution losses (as a share of net generation) has been established for year
2016, in the Government’s ten-year plan . Therefore, allowed losses of all distribution licensees
3
were further adjusted downwards, to enable a target transmission and distribution loss of 12.1%
to be met by year 2015.
(d) The losses of the TL as a share of input to the TL’s network were allowed as filed.
The following corrections were made to the licensee sales forecasts:
(e) The sales forecast filed by the TL for 2012-2015 did not match with the purchases filed by DL1,
2, 3 and 4, who are direct customers of TL. This mismatch was corrected, considering at this
stage, that DLs’ purchase forecasts are correct.
(f) The sale growth forecasts for DL1, 2, 3 and 4 for year 2010 were in the range of 5.5% to 7.0%,
whereas DL5 forecast a 9.9% growth. Sales by DL1, 2, 3 and 4 were increased to represent a
more realistic 7.9% growth for all sales in Sri Lanka in year 2010.
(g) DL5 has filed some of the sales for street lighting as losses. Based on the response to a
clarification, this was corrected and identified under sales.
(h) DL4 has filed a lower sales growth for year 2011 of 1.0%, which was corrected to 5.0%.
Accordingly, in setting tariffs, the Commission proposes to establish the allowed forecast and allowed
losses as shown in Table 3.

10. 3.2 ALLOWED COSTS OF LICENSEES
The Commission observes that the present tariff setting is the first such setting of tariffs after the
licenses were issued in October 2009. Four of the five licenses for distribution are held by Ceylon
Electricity Board (CEB). The Transmission License is also held by CEB. As CEB operated as a single,
vertically integrated utility until the licenses were issued, annual accounts of the functional business
units that hold each license have not been previously prepared. A condition in the license is the
requirement to prepare and submit audited accounts annually to the Commission. Similarly, the
capital expenditure program for at least five years ahead is required to be submitted to the
Commission for approval.
In this Tariff Setting, the Commission intends to waive these two requirements, and has determined
that, (a) a capital expenditure program should be filed by each licensee for Commission approval, by
March 2011, (b) annual audited accounts of year 2010 should be submitted by each licensee by June
2011, and considering the limitation of information currently available for the current tariff setting
that, (c) an extraordinary tariff setting will be conducted in 2011 in which the licensees would file
their revenue requirements for the period 2012-2015 for the approval of the Commission.
3.2.1 DEBT RESTRUCTURING OF CEB LICENSEES
Prior to commencing the tariff setting and associated procedures, the Commission conducted a
detailed assessment of likely costs of each licensee, including the costs of generation, and made such
information available to the Ministry of Finance and Planning, and to the Ministry of Power and
Energy. The analysis indicated that CEB licensees would continue to make losses if the present Tariff
Order of the Commission, issued in April 2009, continues to be applied.
In June 2010, the Commission provided several scenarios of reforms to customer tariffs, to enable
the licensees to move to profitability over the period 2011-2015. The Commission observed that the
costs of generation would continue to increase in real terms until 2013, and would decline thereafter,
with the commissioning of stages 2 and 3 of the Puttalam coal-fired power plant and the Trincomalee
coal-fired power plant. The Commission thus briefed the Government (i) on the large burden of
servicing the debts of DL1, 2, 3, 4 and the TL, and (ii) the need to cushion the costs of the CEB
licensees, directly or indirectly, if their impacts on customer prices are to be managed within
reasonable limits, particularly over 2011-2013.
In assessing the costs of debt, the Commission is guided by the certified minutes of a meeting held at
the Ministry of Finance and Planning on August 6, 2010, chaired by Secretary to the Treasury. The
minutes have been circulated to all the CEB licensees and the Commission. The minutes state, under
item (3) a. “Total outstanding debt stock (of CEB licensees) to the Treasury and (Ceylon
Petroleum Corporation) CPC as at 31.12.2009 should be considered as zero. In other
words, as at 01.01.2010 CEB has no outstanding debt”. Under the same treasury meeting
referred to above, it is noted under item (3) c. “The servicing of debt including repayment of
capital and interest for the investment of about US$3bn (made by the government) during
the period from 01.01.2010 – 31.12.2013 should be borne by CEB. However, CEB need not
bear the cost of interest for the investment made by the government prior to 31.12.2009.
Until a decision is taken, for the purpose of the tariff calculation the interest cost should
not be considered”.
The Commission therefore, requested CEB licensees to take note of the above when filing their
revenue requirement for the period 2011-2015.
The Government, however, has not provided guidance on restructuring of CEB licensees’ short-term
debts.
3.2.2 COSTS OF DISTRIBUTION LICENSEES
The five distribution licensees were provided with a template to submit their costs. The template
follows the principles stated in the approved Methodology for Tariffs. In addition, the licensees were
requested for additional supporting information.
Initially, all the templates were corrected for inaccuracies in formulae. Thereafter, supporting
information provided by each licensee was evaluated and the required adjustments were made to the
costs. The following is a list of such adjustments done.
Consultation Paper on Setting Tariffs for the period 2011-2015 10
11. Distribution Licensees (DL1, 2, 3 and 4):
(i) Long term debts: These commitments (capital repayments and interest payable thereon, and
interest during construction on loans for on-going capital expenditure projects) had been filed by
CEB licensees, in spite of the debt restructuring plan stipulated by the Government (see section
3.2.1). These were removed from the filed costs, and the Licensees were requested to provide a
schedule of restructured debts that would be required to be serviced from 2014 onwards. This
schedule has not been received, and therefore, the present tariff setting has no provision for
servicing long-term debts even after the debt moratorium allowed by the Treasury explained in
section 3.2.1 ends in 2013. The Commission proposes to consider any such debts filed and
associated interest payments, during the extraordinary tariff setting scheduled to commence in
June 2011, if the details of such debts are filed.
(ii) Short-term debts: Licensees have filed the cost of repayment of short-term debts, as
“headquarters overheads”. The Commission observes that such inclusion would cause the
distribution licensee costs to be distorted. The Commission proposes to include such debt
recovery as a levy under the generation pass-through costs (please see further details in section
3.2.7).
(iii) Other revisions:
(a) Operating expenditure (OPEX) and capital expenditure (CAPEX) were mixed in certain filings,
and these were adjusted accordingly. Similarly, VAT and customs duty components associated
with such expenditure were adjusted.
(b) The salary increase of 21.6% included in the filing was allowed for year 2012, considering the
submission that salaries have not been increased in 2010. Thereafter, the salaries remain
constant until 2014. From 2015 onwards, salary increases have been adjusted to be 3.5% in
real terms. The same was applied in assessing the costs of salaries at the headquarters of
each licensee.
(c) Non Salary OPEX was adjusted to increase at the same rate as the customer growth
percentage filed by the licensees.
(d) The non-salary overhead I (Regional Head Quarters Overhead) costs of licensees have been
corrected to remain constant in real terms throughout the tariff period, at the level filed for
2010.
(e) Following information obtained from licensees, the non-amortized customer contribution was
removed from the asset base and included as a separate line item in the revenue template for
calculations
(f) The filed CAPEX allowance for new vehicles was decreased by 50% (from 2011 onwards) as an
interim measure, pending a comprehensive review during the approval process of the CAPEX
program due in March 2011. The forecast depreciation was adjusted accordingly.
(g) OPEX of the retail business was adjusted to increase at the same rate as the customer growth
percentage
(h) Income from sales to street lighting was removed from bad debts.
Distribution licensee DL5:
(i) Salaries of DL5 (LECO) were allowed a 8.5% real increase in 2011, and thereafter, a 3.5% real
increase annually over 2012-2015 was allowed.
(j) Non Salary OPEX was adjusted to increase at the same rate as the customer growth
percentage filed by the licensees.
(k) The non-salary Head Quarters overhead costs have been corrected to remain constant in real
terms throughout the tariff period, at the level filed for 2010.
(l) Following information obtained from the licensee, the non-amortized customer contribution
was removed from the asset base and included as a separate line item in the revenue template
for calculations
(m) CAPEX allowance for new vehicles have been decreased by 50% as an interim measure,
pending a comprehensive review during the approval process of the CAPEX program due in
March 2011. The depreciation forecast was adjusted accordingly.
(n) OPEX of the retail business was adjusted to increase at the same rate as the customer growth
percentage
(o) Bad debts were adjusted by taking out the sales to street lighting, as provided by the licensee,
and added that component as sales.

3.2.3 COSTS OF THE TRANSMISSION LICENSEE
The Transmission Licensee (TL) has two business operations, namely (i) the Transmission Business
(ii) the Bulk Supply and Operations Business (BSOB). In addition, the TL is also the Single Buyer,
purchasing from all the Generation Licensees (GLs). In this sub section, the Transmission and BSOB
businesses are discussed. The single buyer’s business is discussed in the next sub section.
Initially, the TL’s template was corrected for inaccuracies in formulae in the base template provided
by the Commission. Thereafter, supporting information provided by the TL was evaluated and the
required adjustments were made to the costs. The following is a list of such adjustments done.
(a) Long term debts: These commitments were removed on the same basis as for DL1, 2, 3 and 4,
as previously explained.
(b) Short-term debts: These were removed to be included as a levy in the Single Buyer’s pass-
through costs, as previously explained.
(c) Work-in-Progress: A large Work-in-progress (WIP) for on-going projects was observed. This was
allowed, subject to certain projects on which information was not available. Projects that were not
part of the transmission or BSOB, were removed. VAT and financial costs were adjusted accordingly.
(d) In OPEX, with the absence of detailed information, it was assumed that 50% of filed OPEX would be
for salaries, which were allowed to escalate on the basis that a salary increase of 21.6% was
allowed for year 2012, considering the submission that salaries have not been increased in 2010.
Thereafter, the salaries remain constant until 2014. From 2015 onwards, salary increases have
been adjusted to be 3.5% in real terms. The same was applied in assessing the costs of salaries
at the headquarters of the licensee.
(e)It was assumed that 60% of the OPEX filed for Transmission Overheads were salaries, which were
allowed on the same basis as above.(f)CEB Corporate Overheads included a provision for the
settlement of short-term loans. This was removed as described earlier.

3.2.4 REVENUE REQUIREMENTS OF THE SINGLE BUYER
As stated in the approved Methodology for Tariffs, the Single Buyer costs are filed for a period of six
months (January to June). The Commission has the following observations and the corresponding
revisions were made to the filed revenues.
(a) Power Purchase Agreements (PPAs) between the Transmission Licensee and CEB
Generation Licensee (CEB GL): PPAs between TL and CEB GL with respect to each power plant
have not been submitted to the Commission for review and approval, as required in the
Methodology for Tariffs. The Commission observes that depreciation of full generation assets has
been included in the capacity charges of CEB GL’s power plants. As all the long-term debts have
been written off or restructured, CEB GL has no debt repayment or interest commitments in year
2011. Hence there is no justification to charge the full cost of depreciation on CEB GL’s power
plants on customers.
Therefore, the Commission proposes to remove the provision for depreciation included in CEB
GL’s power plant capacity charges. Accordingly, a sum of LKR 6681 million estimated to have
been filed as depreciation charges for year 2011 was removed from the Single Buyer’s filed
generation capacity charges.
However, the investments on these power plants may have included a certain amount of CEB’s
equity, which has to be returned over a period of time. Based on information available to the
Commission, the value of CEB generation assets were estimated to be LKR 267,000 million, on
which CEB’s equity was assumed to be 20%. The Government or CEB have not indicated a desire
to earn a return on equity on this investment.
As a means of providing a return of equity (not return on equity) over a period of 40 years, a sum
of 2.5% of the estimated equity was allowed annually. Accordingly, a sum of LKR 1336 million in
Consultation Paper on Setting Tariffs for the period 2011-2015 15
16. 2011 was provided for the purpose of return of equity, and added to the Single Buyer’s revenue
requirements.
The Commission reiterates that this is an interim arrangement, and that the process of filing the
PPAs between CEB GLs and TL and approval by the Commission should be completed by 31st
December 2010.
(b) Fixed O&M costs of CEB Power Plants: CEB thermal power plant capacity charges filed have a
fixed, non-fuel energy charge of about LKR 2 per kWh. The Commission observes that this charge
is excessive, but has been allowed pending a more comprehensive analysis during the approval of
the CEB GL’s PPAs. The non-fuel energy charge filed for gas turbines at Kelanitissa were not
allowed, owing to the low dispatch of the plant.
(c) Start-stop charges have been filed but estimates for the number of starts-stops have not been
filed.
(d) Pricing of Petroleum fuels: Fuel Supply Agreements (FSA) were not filed with the Commission.
TL provided the most recent invoices or communications with Ceylon Petroleum Corporation
stating the prices, and these were used as the basis for fixing the prices of all petroleum fuels
used for power generation.
(e) Coal pricing: The Fuel Supply Agreement (FSA) has not been submitted to the Commission.
Therefore, the pricing was based on an invoice. The Commission observes the following: VAT has
been included for coal, whereas for other fuels, VAT is not applicable. Therefore, VAT was
removed from coal pricing. A sum of USD 5.65 per tonne has been included as depreciation and
overheads within the price calculation for coal, for which the purpose is unclear. This was not
allowed. A comprehensive pricing formula including any indices to which the pricing is linked,
requires to be filed along with the next Single Buyer’s filing for the period July-December 2011.
(f) Hydropower Dispatch: The Single Buyer has not stated whether the filed hydropower dispatch
would comply with the probability of occurrence of 70% stated in the Methodology for Tariffs. As
the full claw-back provisions are available, the Commission has allowed the filed hydropower
dispatch, pending further clarification in the extraordinary filing due in June 2011.
(g) Dispatch of the coal-fired power plant: The Commission observes that the coal-fired power
plant, operating for the first time in the Tariff Period, has been dispatched only up to an annual
capacity factor of 60%. This has been allowed, pending a complete review of the dispatch
procedure and limitations before the next filing of the Single Buyer, after the power plant
completes its commissioning and reliability testing over the first three months of year 2011.
(h) Un-dispatched power plant: The power plant GT07 has not been dispatched at all during the
six-month period covered in the revenue filing of the Single Buyer, and the filing states that
spares are not available. Capacity charges for this power plant have been filed, but were
removed, pending a final decision by TL and submission of the relevant information to the
Commission. An ex-post adjustment would be allowed for this power plant’s capacity charges,
should the TL dispatch the power plant within the six-month period under consideration, but with
prior approval of the relevant PPA by the Commission.
(i) IPPs not loaded to the rated plant capacity: Some IPPs are not loaded to the full capacity,
stated as the “rated or installed capacity” in the respective PPAs submitted to the Commission.
The Commission has allowed this situation, pending a final determination before the next filing by
the TL for the Single Buyer’s costs.
(j) Northern Power: The IPP identified as Northern Power has a monthly capacity factor of more
than 1.0. The Commission observes that (i) this power plant has not been fully commissioned,
and (ii) the capacity factor of this power plant, serving the isolated network in the Jaffna
peninsula, is likely to be much lower than 1.0. The Commission has assumed that the dispatch is
correct, and that the filed capacity is incorrect. The relevant PPA has not been submitted for
review.
(k) Non-dispatchable (must-run) power plants: In the dispatch filed with the Commission, the
Single Buyer has removed the non-dispatchable (must-run) power plants, all of which are Small
Power Producers (SPPs). No costs of these have been filed. Commission’s views on these power
plants are stated in the next section.
Consultation Paper on Setting Tariffs for the period 2011-2015 16
17. 3.2.5 NON-DISPATCHABLE RENEWABLE ENERGY POWER PLANTS
Upon request from the Commission, TL provided the estimated costs of the non-dispatchable power
plants, which are all Non-conventional Renewable Energy (NCRE) based SPPs. The following
observations and corrections have been made, before such costs are allowed:
(a) Avoided cost calculations: Calculation of avoided costs for year 2011, for payments to
contracts signed before 2007 was not provided. Therefore, the following assumptions were made:
avoided cost-based tariff for year 2011 would be LKR/kWh 11.00 (wet season), 12.00 (dry
season).
(b) Mismatch between avoided costs paid to hydro and biomass, both of which are paid on the same
basis were observed, and corrected.
(c) A biomass power plant in the 3-tier tariff, has a tariff of 22 LKR/kWh, and the rate increases
mid-year. This is not possible based on the tariff methodology for NCRE, and the tariff is
excessive for this power plant, which is licensed as a power plant of the type “Agricultural and
Industrial waste”. The tariff was corrected, and no further revisions will be allowed.
The costs of purchasing non-dispatchable renewable energy power plants, is summarised in Table 6.

could be met. Considering the filed budget of LKR 8969 million for year 2011 for the purchase of
620 GWh (14.46 LKR/kWh), the Commission is of the view that there should be clarity on how these
costs are to be met. As these power plants are non-dispatchable, the Single Buyer has no option to
refuse energy from these power plants, but to purchase from them, even when there can be other
generators which could produce electricity cheaper than 14.46 LKR/kWh.
As an interim measure, the Commission proposes allowing a levy on the Single Buyer’s energy costs,
which would be transparently passed-on to end-use customers. This levy would be allowed on the
basis that the Single Buyer would
(i) fully disclose the detailed tariff schedule for payments to each SPP, in conformity with the
instructions issued by the Ministry of Power and Energy from time to time, and the
announcements made by Sri Lanka Sustainable Energy Authority from time to time, which
have already been made available to this Commission
(ii) submit the detailed calculation of avoided costs payable to some of the SPPs for year 2011
and pending a Government policy guideline on
(iii) how the costs of SPPs are to be met in the future
(iv) any caps on the quantity and price paid to such purchases
(v) any caps on what portion of such costs should be passed-on to electricity customers
The levy on the SB’s pass-through costs allowed for non-dispatchable renewable energy power plants
will be withdrawn, unless the above conditions are met by the SB and the Government’s Policy
Guidelines are received before the next SB’s filing, due in May 2011 for the period July – December,
2011.
In addition a ‘Green Tariff’ is proposed for industrial consumers who desire to purchase green energy
for their products, to recover at least part of this additional cost. A premium of Rs. 3.00/ KWh over
and above their unit rate is proposed.

3.2.7 PROVISION FOR THE SETTLEMENT OF SHORT-TERM DEBTS
As explained earlier, CEB Licensees (DL1-4) and TL filed for a recovery of costs to service the short-
term debts, by embedding such costs in overheads. Upon clarification by the Commission, these were
identified and separated out. Table 8 shows the calculated profile of debt service, to settle these
short-term debts, estimated by the Commission based on the CEB licensee responses to clarifications.

19. The Commission observes that
(i) information provided is inadequate, whereas, the details of each loan, its repayment
schedule, interest payments and interest rates, should have been provided for each month
of the five year Tariff Period.
(ii) copies of the relevant loan agreements should be filed with the Commission
(iii) a statement on how the CEB Licensees would negotiate with the lenders, to gain advantage
of the declining interest rates is required, and
(iv) any actions that would enable the short-term debts to be converted to long-term debts or
other financial instruments, to smoothen the impacts on customers, should be provided
To repay these short-terms debts, the Commission proposes to place a special levy on the pass-
through costs of the Single Buyer, which will be transparently passed-on to customers, and included
in the Bulk Supply Tariff and finally, in the end-use customer tariffs. The Commission would establish
regulatory oversight on the short-term debts, and pass-on any changes to the customers, in each six-
monthly revisions of the Bulk Supply Tariffs.
The amount of this levy to be recovered over the period January to June 2011 is proposed to be
LKR 2800 million, with a full claw-back provision for any variations. If the relevant information
described earlier in this section is not provided, the levy would be completely withdrawn in the next
determination of the Single Buyer’s pass-through tariffs due for the period July-December 2011.

21. 4.2 CONCESSIONS ON FUEL PRICES
The Commission has assessed that the following fuels used in both CEB and IPP generating facilities
are provided at a concessionary price at the time of the filing.
(i) Fuel oil 180 cSt (1500 s) for CEB and IPPs: price 42.55 LKR/litre
(ii) Fuel oil 380 cSt (3500 s) for CEB and one IPP: price 40.00 LKR/litre
(iii) Fuel oil (low sulphur, for West Coast Power Plant): price 52.00 LKR/litre
Based on the evidence of pricing submitted by the Single Buyer, the Commission is of the view that
three other fuels used for generation (coal, auto diesel and naphtha) are priced adequately close to
the international prices, adjusted by the cost of freight and other charges.
The Commission estimates that the fuel subsidy for the period of six-months over January – June
2011 to be LKR 8524 million. In the absence of information filed by the Single Buyer or their fuel
supplier(s), this subsidy is an estimate.

The Commission estimates that the actual cost of the electricity industry in year 2011 would be LKR
19.14 per kWh sold, which has been subsidised by an extent of 21.9% (LKR 4.19 per kWh) by the
Government through (i) the debt write-off and the moratorium, and (ii) concessionary pricing of fuel
prevailing as of the filing date by the licensees.
4.3 PROCEDURE IF SUBSIDIES OR CONCESSIONS ARE
CHANGED
If for any reason, the Government subsidies listed above are not received by the Single Buyer in full,
the ex-post correction provisions in the approved Methodology for Tariffs will be applied and the
Single Buyer will be compensated accordingly, and any expenses would be passed on to customers,
as provided in the approved Methodology for Tariffs.
Similarly, if the Single Buyer receives any direct or indirect subsidies other than those listed above,
such subsidies would be clawed back and passed-on to customers as a discount, as provided in the
approved Methodology for Tariffs.

22. 5. ROAD MAP FOR TARIFF REBALANCING
5.1 INTRODUCTION
Cost to supply each group of consumers were calculated using a technical loss allocation methodology
and it has been found that end-use customer tariffs at present are not cross-reflective. Certain
classes of customers are subsidised, while others pay a surcharge to finance the cross subsidy. The
electricity sector is considered to need LKR 34,293 million in direct and indirect subsidies. Removal of
cross-subsidies among electricity customers and gross subsidies to the sector, requires a step-by-step
approach, considering its socio-economic implications.

The Commission observes that
(i) based on the review of licensee costs and allowed revenues described in previous sections of this
consultation document,
(ii) giving due recognition to the Government for the relief from long-term debts and the currently
applicable concessionary prices on fuel,
(iii) allowing levies to recover short-term debts and excessive payments for renewable energy,
there will be a revenue shortfall of LKR 13,749 million in year 2011, if the present end-use customer
tariffs continue to apply.
The Commission proposes that to cover the revenue shortfall of LKR 13,749 million (LKR 6874 million
for the period January–June 2011), the customer tariffs be restructured with three key objectives:
(i) To increase the total expected revenue by 10.5%, to enable ALL the licensees to be financially
independent from any further grants and subsidies by the Government
(ii) To commence a process of tariff rebalancing, which will progressively move the pricing of
electricity in Sri Lanka to be cost-reflective by year 2015.
(iii) To commence a process of changing customer tariffs in such a manner that in year 2014, CEB
