CAG Audit of Delhi Discoms & Regulatory Assets

Delhi’s CAG Audit of Power Discoms: Constitutional Accountability Meets Energy Regulation

The Delhi government’s decision to order a Comptroller and Auditor General (CAG) audit of the capital’s three electricity distribution companies — BRPL (BSES Rajdhani Power Limited), BYPL (BSES Yamuna Power Limited), and TPDDL (Tata Power Delhi Distribution Limited) — has reignited a long-standing debate about public accountability, regulatory architecture, and the limits of privatisation in a sector that touches every household.

At the centre of this controversy lies a figure that is both staggering and opaque: approximately ₹38,500 crore in accumulated “Regulatory Assets” (RAs) that remain unrecovered — a sum that consumers will ultimately be asked to pay. Understanding why this audit matters requires engaging simultaneously with constitutional law, energy sector regulation, and the doctrine of public accountability.

What Happened

The Cabinet of the Delhi government, chaired by Chief Minister Rekha Gupta, approved a CAG audit of the three discoms. The audit will be the first of its kind since electricity distribution in Delhi was privatised in 2002, unless the discoms successfully seek legal recourse to stall proceedings.

This is not the first time such an audit has been attempted. In 2015, the then AAP-led government sought a similar audit but was blocked by the Delhi High Court. The current government’s attempt therefore navigates contested legal territory, and the discoms retain the option of approaching the courts again.

The RA figures are substantial and discom-specific: BRPL carries the largest burden at ₹19,174 crore, BYPL stands at ₹12,333 crore, and TPDDL at ₹7,046 crore. Notably, Delhi has not seen a tariff hike in over a decade — a politically popular stance that has allowed these deferred costs to balloon.

Adding a further regulatory dimension, in April 2026 the Appellate Tribunal for Electricity (APTEL) rejected a Delhi Electricity Regulatory Commission (DERC) application for a CAG audit and instead directed DERC to begin liquidation of pending RAs within three weeks. The government’s current move thus operates in parallel to — and perhaps in tension with — this tribunal direction.

What Are Regulatory Assets?

Regulatory Assets are deferred expenditures that electricity distribution companies incur — typically arising from changes in fuel costs or shortfalls between the average cost of supply and the revenue actually collected through tariffs and subsidies. When a regulator does not allow a discom to immediately recover a legitimate cost through tariff revision, that unpaid amount is “booked” as a Regulatory Asset — essentially a promise to the discom that the cost will be recovered from consumers in the future.

The mechanism is not inherently improper. In many jurisdictions, regulators use RA creation to smooth tariff shocks for consumers. The concern arises when RAs accumulate unchecked over years, as has happened in Delhi, creating a large deferred burden with no clear timeline for recovery and no comprehensive audit of whether the underlying costs were justified.

The absence of tariff hikes for over a decade, while popular with consumers in the short term, has structurally worsened this problem — costs kept accumulating while the revenue gap remained unaddressed.

The CAG: Constitutional Foundations

The Comptroller and Auditor General of India is established under Articles 148 to 151 of the Constitution. Article 148 provides for the appointment, tenure, and conditions of service of the CAG, modelled on the principle of independence from executive control. The CAG holds office for six years or until the age of 65, whichever is earlier, and can be removed only through a process similar to the removal of a Supreme Court judge — requiring addresses by both Houses of Parliament.

Under Article 149, the duties and powers of the CAG are determined by Parliament, primarily through the Comptroller and Auditor General’s (Duties, Powers and Conditions of Service) Act, 1971. This Act empowers the CAG to audit the accounts of the Union and State governments, as well as bodies substantially financed by government grants or loans.

Article 150 deals with the form in which accounts of the Union and States shall be kept, while Article 151 is the critical accountability link: CAG reports are submitted to the President (for Union) or Governor (for States), who then causes them to be laid before the legislature. This is the constitutional channel through which Parliament’s Public Accounts Committee (PAC) exercises financial oversight — examining irregularities or inefficiencies flagged by the CAG.

The CAG’s independence is often described as the “guardian of the public purse.” Its audit reports have historically been instruments of significant accountability, exposing irregularities in coal block allocations, spectrum assignment, and infrastructure contracts.

Can the CAG Audit Private Discoms?

This is the doctrinal crux of the matter. Delhi’s electricity distribution was privatised in 2002, meaning the discoms are private companies — not government departments or public sector undertakings in the conventional sense. The CAG’s primary jurisdiction extends to government bodies.

However, several legal arguments support the audit’s scope. First, the discoms operate under licences granted by the state and function as natural monopolies — consumers have no choice but to purchase power from the designated discom in their area. This monopoly status, conferred by the state, carries a corresponding public accountability obligation. Second, the CAG’s jurisdiction may extend to bodies that receive substantial government subvention or exercise functions of a public nature. Third, the licence conditions themselves may contain audit provisions. Fourth, consumers bear the financial consequence of RAs — a matter of direct public interest.

The 2015 High Court precedent blocking the AAP-era audit attempt will be highly relevant. Courts will examine whether the statutory and licence framework supports a CAG audit of private entities entrusted with an essential public service.

The Regulatory Architecture: DERC and APTEL

Delhi’s electricity sector is governed under the Electricity Act, 2003, a landmark legislation that unbundled the sector into generation, transmission, and distribution, and mandated the establishment of independent State Electricity Regulatory Commissions (SERCs). DERC (Delhi Electricity Regulatory Commission) is the relevant SERC for Delhi.

DERC is a statutory regulator — it derives its powers from Parliament’s legislation and is independent of the executive government in its day-to-day functioning. It determines tariffs, sets performance standards, and adjudicates consumer complaints. The creation of DERC was intended to depoliticise tariff-setting and insulate it from electoral considerations — precisely the opposite of what occurs when political considerations prevent tariff revisions for a decade.

APTEL (the Appellate Tribunal for Electricity) is the apex adjudicatory body under the Electricity Act for appeals against orders of SERCs. Its April direction to DERC — to begin liquidating pending RAs rather than seek a CAG audit — illustrates a clash between the government’s preferred accountability tool (the constitutional audit) and the sector regulator’s preferred approach (structured tariff-based RA liquidation). The doctrinal tension between executive direction and regulatory independence is a recurring theme in Indian administrative law.

CLAT Concepts to Master

Articles 148–151 and the PAC

CLAT frequently tests the structure and independence of constitutional offices. The CAG is comparable to the Election Commission (Article 324) and the UPSC (Article 315) in its constitutional entrenchment and independence from executive pressure. Know that the CAG’s reports are the foundation for the PAC’s work — the PAC is a joint committee of Parliament that scrutinises government expenditure against CAG findings. The mechanism: CAG audits → Report to President/Governor → Laid before legislature → PAC examination → Executive response.

Statutory Regulators vs. Constitutional Bodies

DERC is a statutory body (created by Parliament’s legislation); the CAG is a constitutional office. This distinction matters for questions on autonomy, jurisdiction, and accountability. Statutory bodies can be modified, merged, or repealed by ordinary legislation; constitutional offices require constitutional amendment to alter fundamentally.

Privatisation and Public Interest

The Delhi discom story illustrates how privatisation of an essential service does not eliminate the need for robust public accountability — it merely shifts the accountability mechanism from direct government control to regulatory oversight and, potentially, constitutional audit. CLAT passages may explore this tension.

Federalism and the Concurrent List

Electricity falls in Entry 38 of the Concurrent List (Seventh Schedule), meaning both Parliament and State Legislatures can legislate on it. The Electricity Act, 2003, is a Central Act, but States establish their own SERCs. This federal dimension explains why DERC is Delhi’s regulator even though the framework legislation is Central.

Conclusion

The CAG audit of Delhi’s discoms is more than a political row between a state government and private utilities. It tests the boundaries of constitutional accountability in a privatised essential service; it reveals the tensions between elected governments, statutory regulators, and appellate tribunals; and it asks a fundamental question that will only become more important as India privatises more public services — when citizens have no market exit option, what mechanisms ensure that the private entity serving them remains publicly accountable?

For CLAT aspirants, this story is a rich laboratory of constitutional, administrative, and regulatory law: the independence of the CAG, the role of Parliament’s PAC, the architecture of India’s electricity sector under the 2003 Act, and the enduring question of how a constitutional democracy holds power — public or private — to account.
