Does a Solar Power Purchase Agreement with a Government Entity Require ERC Approval in India?

In the booming renewable energy sector in India, private solar power developers often enter into Power Purchase Agreements (PPAs) with government corporations or utilities. But a critical question arises: does a power purchase agreement between a private solar power developer and a government corporation require approval by the Electricity Regulatory Commission (ERC)? This issue is pivotal for ensuring legal validity, tariff compliance, and avoiding disputes. This post explores the regulatory landscape under the Electricity Act, 2003, drawing from key judgments and regulations to provide clarity.

While this information is based on established legal precedents, it is for general educational purposes only and not specific legal advice. Consult a qualified lawyer for your circumstances.

The Legal Imperative: Why ERC Approval Matters

Power purchase agreements (PPAs) between private solar developers and government entities are not mere contracts; they fall under stringent regulatory oversight. The main legal finding is that such PPAs typically require prior approval from the ERC for tariffs and key contractual terms to be legally valid and enforceable. This stems from the Electricity Act, 2003, which prioritizes transparency, consumer protection, and public interest. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284

Without ERC nod, unilateral modifications, waivers, or deviations—especially those affecting tariffs—are invalid and challengeable in court. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284 The framework ensures tariffs are set transparently, often via competitive bidding, preventing arbitrary changes. ALL INDIA POWER ENGINEER FEDERATION VS SASAN POWER LTD. - 2016 8 Supreme 439

Legal Framework Under the Electricity Act, 2003

The Electricity Act, 2003, is the cornerstone. Section 86(1)(b) empowers the ERC to regulate electricity purchase and tariffs. Tariffs from PPAs must be approved by the ERC; deviations without prior approval are unlawful. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284

In renewable energy contexts, the ERC's jurisdiction extends to tariffs, obligations, and PPA compliance. Commissioner Of Agricultural Income Tax, Kerala VS Plantation Corporation Of Kerala LTD. , Kottayam - 2000 8 Supreme 53 PPAs must align with the Act and its regulations, mandating ERC-determined tariffs before implementation. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284

Key Regulatory Provisions

Regulatory Oversight in Practice

PPAs with government entities or utilities generally need ERC prior approval for validity. For instance, in one case, PPAs entered on 23.05.2016 were approved by the Karnataka Electricity Regulatory Commission (KERC) on 17.10.2016, highlighting the standard process. Bangalore Electricity Supply Company Limited (BESCOM). VS E. S. Solar Power Pvt. Ltd. - 2021 4 Supreme 120 Supplementary PPAs incorporating KERC-suggested modifications were also executed post-approval. Bangalore Electricity Supply Company Limited (BESCOM). VS E. S. Solar Power Pvt. Ltd. - 2021 4 Supreme 120

Courts have upheld this: Agreements without regulatory approval are invalid, as seen where the court emphasized mandatory prior approval for tariff modifications. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284 Waivers reducing tariffs must similarly be ERC-approved.

Insights from Appellate Tribunal and Supreme Court Cases

Several judgments affirm ERC's role. In appeals before the Appellate Tribunal for Electricity (APTEL), issues like jurisdiction over PPAs were central. For example, in a matter involving Solar Energy Corporation, the PPA execution between respondents was scrutinized, with the State Commission's jurisdiction questioned—but ultimately reinforcing regulatory involvement. M/s Saurya Urja Company of Rajasthan Limited. vs Rajasthan Electricity Regulatory Commission & Ors. - 2021 Supreme(Online)(APTEL) 9M/s Saurya Urja Company of Rajasthan Limited.VersusRajasthan Electricity Regulatory Commission & Ors.

In Ayana Ananthapuramu Solar Private Limited v. Andhra Pradesh Electricity Regulatory Commission, the SERC's interference in a back-to-back PPA's trading margin was examined, underscoring ERC limits yet affirming oversight on key terms. SOLAR ENERGY CORPORATION OF INDIA LIMITED.VersusDELHI ELECTRICITY REGULATORY COMMISSION & Anr.SOLAR ENERGY CORPORATION OF INDIA LIMITED. vs DELHI ELECTRICITY REGULATORY COMMISSION & Anr. - 2021 Supreme(Online)(APTEL) 75

The Supreme Court, in interpreting PPA clauses, clarified that reductions in tariffs are permissible only under specific conditions like delays, but always within approved frameworks. It noted: Power Purchase Agreements (PPAs) were entered into between the parties on 23.05.2016. The Power Purchase Agreements were approved by Karnataka Electricity Regulatory Commission (KERC) on 17.10.2016. Bangalore Electricity Supply Company Limited (BESCOM). v. E. S. Solar Power Pvt. Ltd. and Others - 2021 Supreme(Online)(SC) 498Bangalore Electricity Supply Company Limited (BESCOM). v. E. S. Solar Power Pvt. Ltd. and Others - 2021 Supreme(Online)(SC) 1513

Another ruling stressed: The present consideration has to be ordered in tune with the above conclusions. Accordingly,-- a) the subject Power Purchase Agreements are regulated by the Commission as having its consent and are taken on record. Ecoren Energy India Private Limited VS State of Andhra Pradesh - 2022 Supreme(AP) 176 This binds parties to regulatory orders.

In Madhya Pradesh, a PPA for a 50 MW Solar PV project under the Solar Policy required compliance, with termination reviews dismissed absent fraud proof. M. P. Power Management Company Limited, Jabalpur VS Sky Power Southeast Solar India Pvt. Ltd. - 2020 Supreme(MP) 1218

Unilateral Changes and Exceptions: What to Avoid

Developers or utilities cannot unilaterally alter PPA terms, particularly tariffs. Courts invalidate such moves. KKK Hydro Power Limited VS Himachal Pradesh State Electricity Board Limited - 2025 0 Supreme(SC) 1284 Exceptions are rare; deviations must go through regulatory channels to protect interests. ALL INDIA POWER ENGINEER FEDERATION VS SASAN POWER LTD. - 2016 8 Supreme 439

For instance, in Gujarat, the Commission lacked inherent power to extend control periods or vary PPA tariffs outside statutory procedures. Gujarat Urja Vikas Nigam Limited VS Solar Semiconductor Power Company (India) Private Limited - 2017 7 Supreme 646 This aligns with Section 62 of the Act, where tariffs follow public consultation and cannot be arbitrarily revised.

In Jharkhand cases, deadlines for amended PPAs were extended pending ERC approval, showing flexibility but not waiver of approval. Adhunik Power & Natural Resources Limited VS Jharkhand State Electricity Regulatory Commission - 2018 Supreme(Jhk) 837

Practical Recommendations for Developers and Entities

To mitigate risks:- Secure Prior Approval: Execute PPAs only after ERC approval of tariffs and terms.- Document Amendments: Seek formal ERC nod for any changes or waivers.- Comply with Regulations: Align with Electricity Act, 2003, and state-specific rules like those from KERC or MERC. Coal India Limited VS Vidarbha Industries Power Limited - 2019 Supreme(Del) 1690- Monitor Obligations: Adhere to renewable purchase mandates.

Government entities should enforce transparency, while regulators monitor for fairness.

Key Takeaways

Navigating India's renewable energy regulations demands diligence. Staying updated on ERC guidelines ensures smooth project execution and revenue security. For tailored advice, engage legal experts familiar with state-specific commissions.
