					</table><p>The Uttarakhand Electricity Regulatory Commission (<a href="https://uerc.uk.gov.in/" target="_blank" rel="noopener">UERC</a>) has approved the tariffs determined through competitive bidding for four battery energy storage system (BESS) projects totaling 76 MW/190 MWh in Uttarakhand.</p>
<p>The Commission adopted a tariff of ₹279,782 (~$2,916)/MW/month, excluding goods and services tax (GST), for the 15 MW/37.5 MWh Khatima project; ₹269,832 (~$2,813)/MW/month for the 30 MW/75 MWh Dhakrani project; ₹279,501 (~$2,914)/MW/month for the 16 MW/40 MWh Pathri project; and ₹280,000 (~$2,919)/MW/month for the 15 MW/37.5 MWh Tiloth project.</p>
<p>Patanjali Renewable Energy was selected for the Khatima, Dhakrani, and Pathri projects, while <a href="https://armeeinfotech.com/" target="_blank" rel="noopener">Armee Infotech</a> was selected for the Tiloth project.</p>
<p><a href="https://ujvnl.uk.gov.in/" target="_blank" rel="noopener">UJVN</a> and Uttarakhand Power Corporation (<a href="https://upcl.uk.gov.in/" target="_blank" rel="noopener">UPCL</a>) must also publicly disclose the successful bidders and their quoted tariffs on their websites for at least 30 days after executing the battery energy storage purchase agreements (BESPAs).</p>
<p>The Commission directed UPCL to amend the draft BESPAs in line with its observations, execute them with UJVN and the respective BESS developers, and submit the executed agreements to the Commission within 15 working days of signing.</p>
<p><strong>Background</strong></p>
<p>In April 2025, the Uttarakhand government intended to implement 500 MWh of BESS capacity and sought approval for viability gap funding (VGF). The Ministry of Power subsequently allocated 500 MWh to Uttarakhand under its VGF program for standalone BESS projects supported through the Power System Development Fund. Of this, UJVN was to implement 250 MWh, and UPCL the remaining 250 MWh.</p>
<p>UERC had earlier determined a ceiling capacity charge of ₹396,747 (~$4,136)/MW/month for BESS projects. It later revised the generic capacity charge for standalone BESS projects to ₹259,244 (~$2,703)/MW/month in June 2026. UJVN requested that the earlier ₹396,747 (~$4,136)/MW/month charge be retained for projects to be allotted during FY 2026-27.</p>
<p>The Commission rejected the petitions in July 2026 but allowed UJVN to complete its ongoing competitive bidding process and subsequently approach UERC under Section 63 to adopt the tariffs discovered through bidding.</p>
<p>UJVN argued that it had procured the BESS capacity through a transparent tariff-based competitive bidding process. It proposed procuring capacity from the selected developers and making it available to UPCL.</p>
<p>UJVN sought adoption of the four discovered capacity charges and requested approval of a ₹0.05 (~$0.0005)/kWh margin over the adopted L1 capacity charge for determining the amount payable by UPCL.</p>
<p><strong>Commission&#8217;s Analysis </strong></p>
<p>The Bid Evaluation Committee certified that the bidding, bid evaluation, and selection of successful bidders complied with the applicable BESS guidelines.</p>
<p>UERC compared the discovered charges with BESS procurements in Delhi and Punjab. It noted that Delhi&#8217;s regulator had adopted ₹299,000 (~$3,117)/MW/month, excluding taxes, for a 12.5 MW/25 MWh BESS project, while a 500 MW/1,000 MWh Punjab procurement resulted in charges ranging from ₹335,000 (~$3,492)/MW/month to ₹344,000 (~$3,586)/MW/month. UERC concluded that the charges discovered for the Uttarakhand projects were lower than those cited for Delhi and Punjab.</p>
<p>The Commission consequently adopted the four discovered capacity charges.</p>
<p>On the contractual arrangements, UERC noted that the project-specific BESPAs must conform to the Electricity Act, applicable regulations, bidding documents, and the Ministry of Power&#8217;s BESS guidelines.</p>
<p>It directed UPCL to incorporate a change-in-law provision n the BESPA as such a clause was necessary to address the financial consequences of subsequent changes in laws or government actions and provide contractual certainty.</p>
<p>The Commission noted that UPCL, as the end procurer, should be able to intervene if a BESS developer&#8217;s failure or non-compliance affects the availability, performance, or continuity of storage services and UJVN does not act in a timely manner. Such intervention would not alter the respective contractual roles of UPCL, UJVN, and the developer.</p>
<p>Last month, UERC <a href="https://www.mercomindia.com/uttarakhand-regulator-dismisses-review-of-solar-battery-storage-trading-margins" target="_blank" rel="noopener">rejected</a> a petition seeking reconsideration of the trading margins prescribed for solar and standalone battery storage projects. The Commission noted that the petitioner, UJVN, had not identified any error in its January 6, 2026, order and was raising an issue that had already been considered and decided.</p>

					</table><p>The Uttarakhand Electricity Regulatory Commission (<a href="https://uerc.uk.gov.in/" target="_blank" rel="noopener">UERC</a>) has rejected a petition seeking reconsideration of the trading margins prescribed for solar and standalone battery storage projects.</p>
<p>The Commission noted that the petitioner, <a href="https://ujvnl.uk.gov.in/" target="_blank" rel="noopener">UJVN</a>, had not identified any error in its January 6, 2026, order and was raising an issue that had already been considered and decided.</p>
<p>The Commission observed that the trading margins of 4% for solar projects and ₹0.05 (~$0.0005)/kWh for BESS were specified through the UERC Renewable Energy Regulations (Second Amendment), 2025, and were not determined afresh through the January 6 order.</p>
<p>UERC noted that any change in these margins would require the prescribed regulation-making process and include fresh consultations, rather than a review of the order, and thus rejected a review of the regulations.</p>
<p><strong>Background </strong></p>
<p>UERC notified its Renewable Energy Regulations, 2023, on August 16, 2023, followed by a first amendment in June 2024 and a second amendment on November 27, 2025.</p>
<p>The second amendment introduced provisions concerning BESS, including a levelized ceiling tariff, and prescribed trading margins for BESS and solar projects. For solar projects, it provided a margin of 4% of the L-1 tariff, provided the tariff plus margin did not exceed the generic tariff.</p>
<p>For an intermediary agency implementing BESS for a distribution company, it fixed the trading margin at ₹0.05 (~$0.0005)/kWh, again subject to the applicable generic tariff ceiling.</p>
<p>UJVN asked the Commission to express the BESS ceiling tariff in ₹/MW/month and reconsider the margins for solar and BESS projects. In its January 2026 order, the Commission clarified that the BESS tariff was equivalent to a capacity charge of ₹396,747 (~$4,146.5)/MW/month. It rejected the request to revise the trading margins, holding that the margins had already been determined.</p>
<p>UJVN contended that the existing margins were inadequate to recover recurring manpower, project management, compliance, contractual administration and coordination costs, which would also rise with inflation while the margins remained fixed. It cited the Ministry of Power’s BESS guidelines, which provide for a trading margin of ₹0.07 (~$0.0007)/kWh or 0.5% of capacity charges, as applicable, for an intermediary procurer.</p>
<p>The Uttarakhand Power Corporation (<a href="https://cms.mercomindia.com/daily-news-wrap-up-why-rooftop-solar-is-stalling-in-southern-states/" target="_blank" rel="noopener">UPCL</a>) opposed the petition, arguing that UJVN was attempting to reopen issues already adjudicated. It submitted that review jurisdiction was limited to discovery of new evidence unavailable despite due diligence, an error apparent on the face of the record. According to UPCL, UJVN had neither produced new material nor demonstrated an apparent error.</p>
<p><strong>Commission’s Analysis </strong></p>
<p>Referring to Supreme Court judgments, UERC observed that an error justifying review must be self-evident and cannot require a lengthy process of reasoning. Review cannot operate as an appeal in disguise or allow a party to substitute a different view for one already taken.</p>
<p>On the merits, the Commission distinguished the two issues considered in its January order. The conversion of the standalone BESS ceiling tariff from a per-unit basis to ₹/MW/month addressed an implementation difficulty because BESS tenders across the country are invited and discovered on a capacity-charge basis.</p>
<p>The trading margin, however, was a separate issue relating to compensation payable to the intermediary agency, and UERC found that the prescribed margins did not create an implementation difficulty.</p>
<p>UERC noted that the 4% solar margin and ₹0.05 (~$0.0005)/kWh BESS margin originated in the Second Amendment Regulations notified on November 27, 2025. The January order did not change those margins; it merely declined UJVN’s request to revisit them. Therefore, the January order did not include a separate trading-margin determination that could be modified through review.</p>
<p>The Commission also rejected UJVN’s reliance on the Ministry of Power’s BESS guidelines as a ground for review.</p>
<p>It said the Statement of Reasons accompanying the Second Amendment Regulations showed that the guidelines had already been considered while framing the BESS provisions. They therefore could not constitute new material. UJVN’s request to substitute the regulatory trading margin with the margin specified in the central guidelines would require reconsideration of an issue already examined and decided.</p>
<p>UERC noted that UJVN had not demonstrated an apparent error in the January order and was instead disagreeing with a conclusion already reached after consideration of the issue. Such disagreement, it said, did not amount to an error, and it declined to review the earlier order for trading margin.</p>
<p>Last month, UERC <a href="https://cms.mercomindia.com/maharashtra-regulator-clears-rooftop-solar-plan-for-211206-low-income-homes/" target="_blank" rel="noopener">rejected</a> UPCL’s petition seeking approval to apply an earlier benchmark capacity charge to its 100 MW/250 MWh battery energy storage procurement.</p>

					</table><p><a href="https://ujvnl.uk.gov.in/" target="_blank" rel="noopener">UJVN</a> has invited bids to develop a 90 MW/225 MWh battery energy storage system (BESS) in Uttarakhand.</p>
<p>The BESS will be located near the 132 kV Chilla hydropower substation in Pauri Garhwal.</p>
<p>The estimated project cost is ₹3.52 billion (~$36.99 million).</p>
<p>Only 60 MWh of the project&#8217;s storage capacity will be eligible for viability gap funding (VGF). The VGF support will be capped at ₹1.8 million (~$18,902)/MWh, translating to a maximum grant of ₹108 million (~$1.13 million). The remaining 165 MWh must be developed without grant support.</p>
<p>The last day to submit the bids is August 25, 2026. Bids will be opened on August 28.</p>
<p>Bidders must furnish an earnest money deposit of ₹45 million (~$472,540).</p>
<p>The selected bidder must submit a performance bank guarantee of ₹112.5 million (~$1.18 million) before signing the battery energy storage purchase agreement.</p>
<p>Before the project is declared commissioned, the developer must also furnish a payment security deposit of ₹112.5 million (~$1.18 million), calculated at ₹500,000 (~$5,250)/MWh for the contracted 225 MWh capacity.</p>
<p>The tender requires a minimum local content of 20% of the total project cost, including indigenously developed energy management system application software. Both Class-I and Class-II local suppliers are eligible to participate, subject to the government&#8217;s public procurement preference rules.</p>
<p>Bidders must quote a single monthly capacity charge in ₹/MW for the entire 12-year contract period.</p>
<p>The ceiling tariff has been fixed at ₹318,401 (~$3,343)/MW/month, inclusive of applicable goods and services tax.</p>
<p>The project will be developed under the build-own-operate-and-transfer model. The battery energy storage purchase agreement will remain in force for 12 years from the commercial operation date.</p>
<p>The project must be commissioned within 18 months of the signing of the agreement or the notified start date, whichever is earlier.</p>
<p>The selected bidder will be responsible for the design, engineering, financing, procurement, construction, commissioning, operation, maintenance, and eventual transfer of the project.</p>
<p>The BESS will have a maximum charging and discharging capacity of 90 MW and an initial dispatchable energy capacity of 225 MWh at the delivery point.</p>
<p>UJVNL will provide approximately 12,174 square meters of land near the Chilla substation on a right-to-use basis. The land area is tentative and will be finalized following a joint inspection with the developer.</p>
<p>The developer must construct the BESS and all associated evacuation infrastructure up to the delivery point at its own cost. This includes the dedicated 132 kV transmission line, transformers, switchgear, protection systems, metering and communication equipment, terminal equipment, and the project bay at the Chilla substation. It must also obtain the necessary statutory approvals and grid connectivity.</p>
<p>Grid electricity will be supplied to charge the BESS, accounting for expected conversion losses. The stored power will be discharged during peak periods or as per instructions issued by the State Load Dispatch Center, in consultation with UJVNL and Uttarakhand Power Corporation.</p>
<p>The BESS must remain available for up to two complete charge-discharge cycles per day. The maximum permitted transition or cooling time between charging and discharging, or vice versa, is 1 hour, while the recovery time for a complete cycle cannot exceed 2 hours.</p>
<p>The developer must guarantee a minimum monthly AC-to-AC round-trip efficiency of 85%. If efficiency falls below 70%, the developer will be liable to pay liquidated damages for excess conversion losses based on the distribution companies&#8217; average power purchase cost for the previous financial year, and the corresponding monthly tariff payment will not be made.</p>
<p>The project must maintain annual system availability of at least 95%. A shortfall will attract liquidated damages calculated at twice the capacity charges attributable to the unavailable capacity, in accordance with the formula prescribed in the tender.</p>
<p>The minimum dispatchable capacity must remain at 97.5% of the initial capacity at the end of the first year, 95% at the end of the second year, and 92.5% at the end of the third year. It will gradually decline to 70% by the end of the twelfth year. The developer must submit an annual available-energy test report in accordance with IEC 62933-2-1.</p>
<p>Bidders must demonstrate a firm technology tie-up, collaboration, or supply agreement with a battery storage technology or equipment supplier. The proposed technology must be commercially established and operational.</p>
<p>To qualify technically, a bidder must meet at least one of the prescribed experience criteria. It may be an original equipment manufacturer of containerized battery energy storage systems, or an entity holding an Indian manufacturing license from a BESS manufacturer, with cumulative supplies of at least 100 MWh and at least one successfully commissioned project of 45 MWh or more.</p>
<p>Alternatively, the bidder may have commissioned a standalone or co-located BESS project of at least 45 MWh as an engineering, procurement, and construction contractor or developer.</p>
<p>Renewable energy developers and EPC contractors may also qualify if they have commissioned cumulative solar, small hydropower, or wind projects totaling at least 45 MW that have operated satisfactorily for at least six months and are connected to the grid at 33 kV or above. Alternatively, they may demonstrate one project of at least 25 MW meeting the same operating and grid-connectivity requirements.</p>
<p>The tender also permits qualification based on experience in designing, engineering, and constructing substations ranging from 33 kV to  400 kV. Such bidders must have completed projects with a cumulative value of at least ₹400 million (~$4.20 million) during the previous seven years, with the facilities operating satisfactorily for at least two years. Experience gained solely as a subcontractor to the principal EPC contractor will not be considered.</p>
<p>Bidders must have a minimum net worth of ₹7.4 million (~$77,707)/MW of quoted capacity. For the full 90 MW project, this translates to a minimum net worth requirement of ₹666 million (~$6.99 million). They must also have reported a profit in at least one of the three preceding financial years.</p>
