Regulatory asset

Indian Economy glossary

Also called: Regulatory assets · Topic: Infrastructure: Transport, Communications and Energy · NCERT: Beyond NCERT

Meaning

A regulatory asset is the part of a discom's (power distribution company's) approved cost of supply that the electricity regulator does not let it charge in today's tariff, usually to avoid an unpopular price rise. The regulator records it as money that consumers owe the discom, to be recovered later through higher tariffs, with interest added for the waiting period.

It matters because it makes today's power bills look cheap and a discom's accounts look healthy, while a growing bill is passed on to future consumers. In August 2025 the Supreme Court ordered all pending regulatory assets cleared by 1 April 2028.

Explanation

How it is created

  • Step 1: the regulator fixes the tariff.
  • Under the Electricity Act 2003, a State Electricity Regulatory Commission (SERC) works out the discom's cost of supply. This covers buying power, transmission charges, staff, repairs and interest.

  • Normally the tariff is set to recover that full cost.

  • Step 2: the regulator holds the tariff down.

  • If recovering the full cost would mean a sharp tariff hike, the regulator may approve only part of it.

  • Step 3: the gap is carried forward, not written off.

  • The unrecovered cost becomes a "regulatory asset" in the discom's books.

  • It is called an asset because it is a future claim. The discom expects to collect this money from consumers in later years.

  • Step 4: interest is added.

  • The discom has to borrow to cover the gap in the meantime. This is called a carrying cost.
  • The longer recovery is delayed, the bigger the final bill.

Worked example (illustrative numbers)

  • Approved cost of supply: ₹8 per unit. Units sold in a year: 1,000 crore.
  • The regulator allows a tariff of only ₹7 per unit.
  • Gap = ₹1 × 1,000 crore units = ₹1,000 crore regulatory asset.
  • Suppose interest is 10% a year and recovery waits 3 years: ₹1,000 × 1.1 × 1.1 × 1.1 ≈ ₹1,331 crore.
  • The result: consumers saved ₹1,000 crore earlier but now owe about ₹1,331 crore. If new gaps keep being added every year, the total keeps growing.

Why regulatory assets pile up

  • Political pressure: regulators may avoid tariff hikes, especially before elections.
  • Sudden cost increases: costlier coal or power purchases that the regulator does not pass on at once.
  • Delayed or missed true-ups: the regulator does not match actual costs against approved costs on time.
  • Weak regulators: in its August 2025 judgment, the Supreme Court said DERC (the Delhi regulator) itself had failed to follow the rules on creating and recovering these dues.

What brings them down

  • Tariff increases spread over a set period, called "liquidation" of the regulatory asset.
  • Lower costs: cutting AT&C losses (power lost to technical faults, theft and unpaid bills) shrinks the gap.
  • Firm deadlines from courts or tribunals, and road maps published by SERCs.

In India

  • Legal basis: the Electricity Act 2003 created CERC and the SERCs. SERCs fix retail tariffs and decide whether to create a regulatory asset and how to recover it. Electricity is in the Concurrent List (entry 38).
  • Supreme Court, August 2025:
  • All pending regulatory assets must be cleared by 1 April 2028.
  • Any new regulatory asset must be cleared within three years.
  • Each regulatory commission must publish a road map for clearing the old ones.

  • Regulatory commissions should carry out intensive audits of why discoms are not recovering their costs.

  • Delhi case:

  • More than ₹38,500 crore of regulatory assets are pending in Delhi alone.
  • In April 2026, APTEL (the Appellate Tribunal for Electricity) rejected DERC's plan to have the CAG audit the discoms. It told DERC to issue an order to clear the dues within three weeks.

  • On 3 July 2026, the Supreme Court stayed the Delhi government's order for a CAG audit of the private discoms BRPL, BYPL and TPDDL.

  • CAG angle: the CAG's horizontal performance audit of discoms looks at one issue across many states at once. It can show which states built up these dues, and why.

  • Discom finances:
  • Discoms made a combined profit of ₹2,701 crore in FY25.
  • Their accumulated losses (all past losses added together) were about ₹6.47 trillion at the end of FY25.

  • Regulatory assets raise a question about whether that profit is real or just costs pushed into later years.

  • Link to RDSS: the Revamped Distribution Sector Scheme (2021) targets an ACS–ARR gap of zero. Hiding the gap in a regulatory asset does not actually close it.

Don't confuse with

  • ACS–ARR gap: this is the gap between the average cost of supply and the average revenue a discom actually realises per unit, so it measures a loss. A regulatory asset is the part of that gap the regulator formally approves as recoverable from consumers later.
  • Regulatory liability: the opposite case. The discom has collected more than its approved cost, so the extra money must be returned to consumers through lower future tariffs.
  • Cross-subsidy: some consumers (industry, commerce) pay above cost so that others (farmers, poor households) can pay below it, within ±20% of the average cost of supply under the Tariff Policy. Here the cost moves between consumer groups today. A regulatory asset moves cost from today's consumers to future consumers.
  • AT&C losses: power that is lost or never paid for, because of technical faults, theft or unpaid bills. That is a loss of efficiency. A regulatory asset is a decision about tariff timing, and it can exist even in a discom with low losses.

Prelims Hooks

  • A regulatory asset is created by the State Electricity Regulatory Commission, not by the discom or the state government, when it approves a tariff below the cost of supply.
  • It is recovered from future consumers through higher tariffs, with carrying cost (interest) added. It is not a grant from the government.
  • Supreme Court (August 2025): pending regulatory assets to be cleared by 1 April 2028, new ones within three years, and SERCs to publish road maps.
  • Delhi: more than ₹38,500 crore of regulatory assets pending. In April 2026, APTEL ordered DERC to clear them within three weeks.
  • Trap: "A regulatory asset is a physical asset of the discom, such as a substation." FALSE. It is an accounting claim on money to be collected from consumers in the future.
  • SERCs and CERC were created under the Electricity Act 2003. Electricity is Concurrent List entry 38.

Mains Points

  • Short-term relief, long-term burden: regulatory assets keep tariffs low today but shift the cost, plus interest, onto future consumers. They also weaken discoms' cash flow, which leads to late payments to power generators.

  • Use this point to argue for cost-reflective tariffs and an independent regulator, in line with the Supreme Court's 2028 deadline and road maps.

  • Accountability and audit: regulatory assets let a discom report a "profit" while costs are pushed into later years. A horizontal CAG audit could compare states on how they handle them.

  • The limit: whether the CAG can audit private discoms such as Delhi's is still undecided, after the Supreme Court's stay of 3 July 2026 and APTEL's April 2026 order.

  • The draft Electricity (Amendment) Bill, 2025 could settle who audits public money handled by private discoms.

  • Link to power-sector reform: RDSS's target of a zero ACS–ARR gap means little if the gap is only hidden in regulatory assets. The lasting fix is to cut AT&C losses, pay subsidies on time and revise tariffs every year. That keeps new regulatory assets from building up.
