IESCO Asks NEPRA for Rs 157.9 Billion in Past Costs, 38% of the Ten Power Companies' Claims

Islamabad Electric Supply Company (IESCO) has asked NEPRA to approve Rs 157,864 million, about Rs 157.9 billion, in "prior year adjustments" for 2027. That is the largest claim of the ten government-owned power companies, and about 38 per cent of the Rs 415.3 billion they ask for together. NEPRA hears IESCO on Thursday 15 October 2026.

We opened all ten hearing notices on nepra.org.pk and added up the prior year line ourselves. The notices show the figures in "Rs in Million". Nothing here is decided yet. These are requests.

IESCO's past cost claim is the biggest of ten

A prior year adjustment, or PYA, is money a company says it should have recovered in earlier years but did not. IESCO claims Rs 157,864 million. Faisalabad's FESCO comes second at Rs 56,973 million, and Multan's MEPCO third at Rs 51,480 million.

IESCO's claim is about twice its own requested margin of Rs 78,120 million for 2027. A margin is the money a company asks to cover its running costs, depreciation and return on assets, after other income. So the past-cost claim alone is larger than what IESCO asks to run the network for a year.

The ten notices were posted between 24 and 27 September. Our earlier piece on the 2027 tariff hearings of all ten companies lists every hearing slot. This page adds up the PYA lines side by side.

The ten claims add up to Rs 415.3 billion

Added together, the ten companies claim Rs 415,302 million in prior year adjustments. IESCO alone is 38 per cent of that. The three smallest claims, from HESCO, TESCO and GEPCO, together come to Rs 39,532 million.

All hearings are held at NEPRA Tower in Islamabad and on Zoom. K-Electric is not part of this round.

Why a past-cost claim matters to your bill

If NEPRA allows a prior year adjustment, the money is added to the revenue the company may collect, and it can end up in the consumer tariff. NEPRA decides first. Under the NEPRA Act, the federal government then notifies the tariff that reaches your bill.

The notices do not say how much per unit any claim would add. We cannot work that out from the notice alone, because it does not give the units each company expects to sell. So we do not give a rupees per unit figure.

The PYA line also includes the PPMC fee, shown in brackets in each notice. PPMC is the Power Planning and Monitoring Company, and that wording is NEPRA's own.

Most notices place the line under supply of power. FESCO and TESCO split it between distribution and supply. We add the totals as each company filed them.

The unit in the notices is million rupees

The notices for IESCO, MEPCO, PESCO, QESCO, FESCO, GEPCO, HESCO and TESCO print "Rs. In Million" above the table. LESCO and SEPCO do not print the unit. We read their figures in the same unit because their totals line up with the other companies' tables. We could not confirm that on the notices themselves.

That is why we write Rs 157,864 million and not a bare number. A reader who skips the unit could mistake Rs 158 billion for Rs 158 million.

You can comment before the hearing ends

NEPRA invites any interested or affected person to send written comments or speak at the hearing. IESCO is heard on 15 October at 2:00 pm. The notice gives a Zoom link and meeting ID, and the NEPRA Registrar's phone number, 051-2013200.

1. Open nepra.org.pk and find your company's notice of hearing.
2. Read the claim table and the date and time.
3. Write your comment on one point, for example the PYA line.
4. Send it to the NEPRA Registrar before the hearing, or join the Zoom call.
5. Keep a copy of what you sent.

Common questions

What is a prior year adjustment in a power company tariff?

It is money a company says it did not recover in earlier years, which it asks to add to the revenue it may collect. NEPRA checks each claim at a hearing and decides how much to allow.

How much has IESCO asked for?

IESCO claims Rs 157,864 million as a prior year adjustment, and a total requested revenue of Rs 530,169 million for 2027, which includes the cost of buying power.

Will my electricity bill go up because of these claims?

Not yet. These are requests, and NEPRA has not decided them. A change reaches your bill only after NEPRA decides and the federal government notifies the tariff.

Does this apply to K-Electric customers in Karachi?

No. K-Electric is not part of this round of hearings. Its tariff runs on a separate determination.

Can an ordinary consumer speak at the hearing?

Yes. The notices invite any interested or affected person to send written or oral comments, and to join through Zoom.

How we verified this

What we checked, where we read it, and what we could not confirm.

Last checked on 13 October 2026, Pakistan time. We read NEPRA's notices of hearing for the ten companies, posted in September 2026. The sums, shares and comparisons with each company's margin are our own arithmetic. The LESCO and SEPCO notices do not print the unit. We have not seen any company's reply to the hearing questions.
