					</table><p>The Uttar Pradesh Electricity Regulatory Commission (<a href="https://www.uperc.org/Default2.aspx" target="_blank" rel="noopener">UPERC</a>) has approved the power sale agreement (PSA) and supplementary power sale agreement (SPSA) between Uttar Pradesh Power Corporation (<a href="https://uppcl.org/uppcl/" target="_blank" rel="noopener">UPPCL</a>) and National Hydroelectric Power Corporation (<a href="https://www.nhpcindia.com/" target="_blank" rel="noopener">NHPC</a>) for procuring 1,525 MW of solar power.</p>
<p><strong>Background</strong></p>
<p>NHPC, designated by the Ministry of New and Renewable Energy (MNRE) as an intermediary procurer or renewable energy implementing agency, conducted a competitive bidding process for 3,000 MW of interstate transmission system (ISTS)-connected solar projects.</p>
<p>Initially after the tender, the petitioner, UPPCL, was to procure 1,500 MW of solar power, but a further 25 MW was added through an SPSA, increasing the total purchasing capacity to 1,525 MW.</p>
<p>The additional 25 MW, initially allocated to the Military Engineering Services (MES), was reallocated to the petitioner after MES failed to sign the agreement.</p>
<p>Following the allocation, UPPCL approached UPERC, seeking approval for its PSA and SPSA with NHPC and the discovered tariff. NHPC stated that the Central Electricity Regulatory Commission (CERC) had already adopted the discovered tariff of ₹2.52 (~$0.029)/kWh in an earlier order.</p>
<p>UPPCL submitted that the agreements would help meet the state’s RPO targets and optimize the power purchase cost for consumers.</p>
<p><strong>Commission’s Analysis</strong></p>
<p>UPERC approved the PSA and SPSA, considering UPPCL’s requirement to meet its RPO targets.</p>
<p>The Commission noted procedural issues with NHPC proceeding with the 3,000 MW bid quantum without prior approval from procurers, which caused delays. It advised NHPC to obtain the procurer&#8217;s consent before initiating the bidding process in the future.</p>
<p>Additionally, the Commission approved the procurement of 1,525 MW of solar power at the requested tariff of ₹2.52 (~$0.029)/kWh, with a trading margin of ₹0.07 (~$0.00081)/kWh.</p>
<p>However, to safeguard solar power developers, the Commission held that if NHPC fails to provide an escrow mechanism or an irrevocable, unconditional revolving letter of credit, the trading margin would be limited to ₹0.02 (~$0.00023)/kWh.</p>
<p>The Commission instructed UPPCL to comply with its earlier order by negotiating future trading margins below ₹0.07 (~$0.00081)/kWh for long-term PPAs with intermediaries or trading licensees.</p>
<p>Recently, UPERC <a href="https://www.mercomindia.com/uperc-approves-tariff-for-5-mw-of-bagasse-based-rtc-power-procurement" target="_blank" rel="noopener">approved</a> NIDP Developers’ request for a tariff of ₹5.95 (~$0.07)/kWh for procuring 5 MW of bagasse-based round-the-clock (RTC) power between April 1, 2025, and July 31, 2025.</p>

					</table><p>The Andhra Pradesh Electricity Regulatory Commission (<a href="https://aperc.gov.in/" target="_blank" rel="noopener">APERC</a>) has approved a tariff of ₹4.6 (~$0.0544)/kWh for the Southern Power Distribution Company of Andhra Pradesh (<a href="https://www.apspdcl.in/" target="_blank" rel="noopener">APSPDCL</a>) to procure 400 MW from <a href="https://axisenergy.in/" target="_blank" rel="noopener">Axis Energy</a>&#8216;s wind-solar hybrid projects.</p>
<p>The Commission has ordered the distribution company to consider that the energy injected into the grid will be treated as banked energy. APSPSCL may purchase this energy at 50% of the pooled power purchase cost.</p>
<p>It approved the power purchase agreements (PPA) with the requested tariff of ₹4.6 (~$0.0544)/KWh.</p>
<p><strong>Background</strong></p>
<p>The petitioner, APSPDCL, sought to procure 100 MW of wind-solar hybrid power each from Axis Energy Ventures&#8217; four solar parks under the 400 MW pilot project of the bundling, balancing, and banking program.</p>
<p>The program mandates a capacity utilization factor (CUF) of over 60%, a stable Andhra Pradesh Public Service Commission (APPC) tariff, and 50:50 renewable energy certificate benefit sharing and other local economic benefits.</p>
<p>The petitioner entered a power purchase agreement (PPA) with Axis Energy Venture&#8217;s four solar parks and approached the Commission to approve the PPAs.</p>
<p>APERC rejected the petitioner’s request, seeking further clarification.</p>
<p>The Commission sought justification for the petitioner’s procurement of 400 MW of wind-solar hybrid power and fixing a pooled power purchase cost for a 25-year PPA duration.</p>
<p>The petitioner submitted that wind-solar hybrid power will provide round-the-clock power to meet the state&#8217;s power needs and help the state meet its renewable purchase obligations (RPOs). It added that additional renewable energy projects are needed to achieve its 24% RPO target by 2026-27.</p>
<p>It also highlighted that hybrid projects would help achieve a higher CUF of above 60%, ensuring continuous power availability.</p>
<p>It added that procuring power projects after the interstate transmission system waiver ends would increase bids by ₹0.95 (~$0.011)/kWh to ₹1.28 (~$0.015)/kWh. The petitioner also said it would be economical for the state to procure from a project that only utilizes the state transmission utility network, such as this one.</p>
<p>However, the Transmission Corporation of Andhra Pradesh responded that it could not intermittently balance renewable energy or provide banking services. Accordingly, the Commission permitted the APSPDCL to file the amended PPA.</p>
<p>APSPDCL said the developer must ensure an energy storage system (ESS) and the power project.</p>
<p>It further requested that the Commission mandate the developer to provide peak hour supply for two hours each in the morning and the evening. The petitioner said that the developer must ensure 90% availability of the contract capacity during these peak hours.</p>
<p>Additionally, the petitioner requested the Commission to approve the APPC tariff applicable for 24 months from the date of approval of the draft PPAs approved in FY 2021-22. Referring to that approval, it requested the Commission to allow the tariff of ₹4.6 (~$0.0544)/kWh instead of ₹5.12 (~$0.06)/kWh per the current APPC tariff.</p>
<p>Axis Energy Ventures also proposed the following changes to the PPA:</p>
<ul>
<li>Provision of firm power for two hours during morning and evening peak hours by installing ESS. Axis Energy will ensure 90% availability of contracted capacity.</li>
<li>The company will maintain a 500 MW power evacuation capacity with delivered energy calculated based on the contracted capacity.</li>
<li>If generated power exceeds 500 MW, the petitioner has the right of first refusal. The excess power can then be sold to third parties or power exchanges.</li>
<li>Use of existing infrastructure for charging and delivering power from energy storage systems without additional charges</li>
<li>Provision to allow a one-time change in the renewable energy configuration until the commercial date of operation</li>
<li>Proposal for a more granular penalty structure for not meeting the 60% CUF</li>
<li>Application of late payment surcharge</li>
<li>Clarification on the calculation of delivered energy</li>
<li>Acceptance of APPC tariff determined for FY 2021-22 for 25 years</li>
</ul>
<p><strong>Commission&#8217;s Analysis</strong></p>
<p>The Commission recognized the petitioner’s need to procure power from wind-solar hybrid power projects to meet growing power demand, grid stability, and RPO targets.</p>
<p>The regulator changed the peak hours to 5 AM, 9 AM, and 7 PM to 11 PM, stating that peak hour demand shifts are expected due to the large-scale adoption of solar.</p>
<p>It approved the PPAs with the requested tariff of ₹4.6 (~$0.0544)/KWh, which is also lower than the tariff discovered in a Solar Energy Corporation of India&#8217;s 1.2 GW wind-solar hybrid auction.</p>

					</table><p>The Gujarat Electricity Regulatory Commission (<a href="https://gercin.org/" target="_blank" rel="noopener">GERC</a>) has approved a predetermined levelized tariff of ₹2.95 (~$0.034)/kWh to procure power from decentralized solar and other renewable energy projects under Component-A of the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) program.</p>
<p>This decision follows a petition filed by the state&#8217;s four distribution companies (DISCOMs): Paschim Gujarat Vij Company, Madhya Gujarat Vij Company, Uttar Gujarat Vij Company, and Dakshin Gujarat Vij Company.</p>
<p>The Commission directed the DISCOMs to proceed with power procurement at the approved rate for a limited period to facilitate PM-KUSUM’s implementation.</p>
<p><strong>Background</strong></p>
<p>The petition was initiated by the Gujarat DISCOMs seeking approval for the ₹2.95 (~$0.034)/kWh tariff for projects under Component-A of the PM-KUSUM.</p>
<p>The petitioners submitted that the requested tariff was economically viable, lower than their average power purchase cost (APPC), and within the range of recent solar bids.</p>
<p>Additionally, the petitioners said the tariff was calculated considering the Ministry of New and Renewable Energy’s capital cost benchmarks and reasonable returns for developers.</p>
<p><strong>Commission&#8217;s Analysis</strong></p>
<p>The Commission observed that the requested tariff was marginally higher than the lowest recent competitive solar tariffs. However, it deemed this difference justified due to the projects’ decentralized nature and smaller scale (up to 2 MW), noting that such projects typically incur higher per-unit costs due to limited economies of scale and comparatively complex grid integration.</p>
<p>The Commission also recognized that the small-scale projects will significantly impact the public policy goals of promoting renewable energy, empowering farmers, and contributing to energy security. Additionally, GERC observed that the tariff was still lower than the petitioners’ APPC and economically viable.</p>

					</table><p>The Appellate Tribunal for Electricity (<a href="https://www.aptel.gov.in/en" target="_blank" rel="noopener">APTEL</a>) has set aside the Karnataka Electricity Regulatory Commission’s (<a href="https://kerc.karnataka.gov.in/en" target="_blank" rel="noopener">KERC</a>) order rejecting a petition by <a href="https://www.herofutureenergies.com/" target="_blank" rel="noopener">Hero Future Energies</a> requesting a power purchase agreement (PPA) execution date extension.</p>
<p>APTEL remanded the case to the state regulator for a fresh evaluation. It directed KERC to re-examine the legitimacy of the commissioning timeline extension that was granted to the appellant and the resulting claim for ₹120.5 million (~$1.405 million) in liquidated damages sought by HESCOM.</p>
<p><strong>Background</strong></p>
<p>The appellant, Hero Future Energies, executed a PPA with HESCOM in 2014 for its 50 MW solar project. The PPA included a provision for dispute resolution through arbitration.</p>
<p>HESCOM sought KERC’s approval for the PPA. The Commission approved the PPA, subject to removing the arbitration clause.</p>
<p>The appellant requested the extension of the PPA execution date to when HESCOM informed it about KERC’s decision. Hero Future Energies reasoned that it faced issues with financing the project because it did not have the original PPA copy, and lending institutions considered it effective only after a regulatory commission’s approval.</p>
<p>HESCOM accepted the date extension, and both parties signed a supplementary PPA to accommodate the request. The distribution company then approached KERC to approve the supplementary PPA.</p>
<p>The Commission highlighted certain deficiencies in the PPA and directed the reduction of the project tariff from ₹7.47 (~$0.089)/kWh to ₹6.50 (~$0.077)/kWh since this tariff was applicable on the project commissioning date.</p>
<p>The appellant approached KERC seeking a declaration of ₹7.47 (~$0.089)/kWh as the tariff and the supplementary PPA’s approval. The Commission approved the tariff but denied the extension granted by HESCOM to the appellant.</p>
<p>After KERC’s decision, HESCOM claimed ₹120.5 million (~$1.405 million) from the appellant as liquidated damages for the extended period. The appellant approached APTEL, seeking approval for the extension period.</p>
<p>It argued that the time extension provided by HESCOM was valid; therefore, the claim for liquidated damages was without merit. It submitted that the project was delayed because of circumstances beyond its control and that HESCOM&#8217;s delay in providing necessary approvals and actions contributed to the commissioning delay.</p>
<p>HESCOM maintained that liquidated damages were applicable due to Hero Future Energies&#8217; failure to meet the original PPA commissioning timelines.</p>
<p><strong>Tribunal’s Analysis</strong></p>
<p>APTEL instructed KERC to determine the appropriate financial restitution for the appellant, including the methodology for calculating interest in any delayed payments. This includes determining the appropriate financial compensation for the appellant, specifying whether the interest calculation should be simple or compound, and establishing the applicable interest rate.</p>
<p>Recently, the APTEL <a href="https://www.mercomindia.com/aptel-dismisses-wind-developers-plea-for-banking-regulations-relaxation" target="_blank" rel="noopener">dismissed</a> a petition filed by the Siddhayu Ayurvedic Research Foundation seeking to relax the banking regulations under the Distribution Open Access Regulations due to the impact of the COVID-19 pandemic.</p>
