India added 48.4 MWh of energy storage capacity in the first half (1H) of 2025, a 74% decline from 186 MWh added in the same period last year, according to the newly released India’s Energy Storage Landscape 1H 2025 Report by Mercom India Research. India’s cumulative installed energy storage capacity reached 490 MWh by the end of June 2025. Solar-plus-storage systems accounted for nearly 56% of India’s cumulative installed capacity. This was followed by more than 32% from solar-plus-wind projects with round-the-clock capability, and over 12% from standalone battery energy storage systems. The remaining share came from floating solar with storage, and solar-plus-wind projects with storage capabilities.

Dilip Buildcon, through its joint venture (JV) with DBL-APMPL, won Madhya Pradesh Jal Nigam’s (MPJN) auction for developing a 100 MW solar project at Madhya Pradesh’s Ramnagar and Dhanwada villages. The JV has a shareholding pattern of 74% by Dilip Buildcon and 26% by APMPL. The project will supply power to MPJN for 25 years from the date of commissioning at a power supply rate of ₹2.09 (~$0.023)/kWh with non-domestic content requirement panels. MPJN floated the tender for the project in July this year. The Bhopal-based infrastructure development company said in a regulatory filing that it had received the letter of acceptance for the solar project.

The Appellate Tribunal for Electricity set aside an order of the Rajasthan Electricity Regulatory Commission (RERC) dismissing a petition by a wind energy developer over repeated curtailments of its 120 MW project in Jaisalmer, Rajasthan. The Tribunal found merit in the appellant’s case, partly allowing compensation claims, and remanding other issues to RERC for detailed reconsideration within three months. Tanot Wind Power set up a 120 MW wind project in three phases between June and December 2015 after executing two power purchase agreements with Jaipur Vidyut Vitran Nigam in February and May 2015.

The Madhya Pradesh Electricity Regulatory Commission approved a joint petition filed by Rewa Ultra Mega Solar (RUMSL) and MP Power Management Company to exclude a Goods and Services Tax reduction from the scope of “change in law” under the power purchase agreement for solar park projects at Morena, Madhya Pradesh. RUMSL is conducting the bidding process under scrutiny in accordance with the Ministry of Power’s “Guidelines for Tariff-Based Competitive Bidding Process for Procurement of Power from Grid-Connected Solar PV Power Projects,” issued under Section 63 of the Electricity Act, 2003.

The Maharashtra Electricity Regulatory Commission (MERC) approved deviation volume limits for distribution licensees and deemed distribution licensees (DISCOMs) with peak demand up to 250 MW, adopting Maharashtra State Load Dispatch Center’s “Case-C” demand slab approach. For DISCOMs with peak demand above 250 MW, the deviation volume limit will continue to be determined by the non-coincident peak demand-based formula under the MERC’s deviation settlement mechanism Regulations, 2019. Provisional limits communicated by the Commission on March 28, 2025, are now treated as final for the financial year 2025–26.

The Gujarat Electricity Regulatory Commission partly allowed a petition filed by a wind energy developer, granting a 396-day extension for completing the evacuation infrastructure for its 40 MW wind project connected to the 220 kV Savarkundla substation. The petition sought a declaration that the delay was due to unforeseeable circumstances not attributable to the petitioner, a 12-month extension for completion of the evacuation system, interim protection against coercive action, such as bank guarantee encashment, and other consequential reliefs. The Commission found merit in the petitioner’s submissions to the extent of granting a 396-day extension, but did not issue a separate order regarding the bank guarantee.

V.O. Chidambaranar Port Authority invited bids to commission a 2 MWh battery energy storage system in Thoothukudi, Tamil Nadu. Bids must be submitted by October 28, 2025. Bids will be opened on October 29. Bids must be submitted by October 28, 2025. Bids will be opened on October 29. The BESS must deliver 400 kW of continuous power output for five hours, with an AC-to-AC round-trip efficiency of 85% at rated power and an annual availability of 90%. Cell chemistry must be lithium-ion, lithium iron phosphate, or an equivalent proven technology.

Solar module manufacturer Waaree Energies approved an additional capital expenditure of ₹80 billion (~$901.47 million) in its wholly owned subsidiary Waaree Energy Storage Solutions to expand the production capacity of its lithium-ion advanced chemistry storage cell and battery energy storage system manufacturing plant from 3.5 GWh to 20 GWh. The company also approved an additional capital expenditure of ₹1.25 billion (~$14.09 million) in its wholly owned subsidiary Waaree Clean Energy Solutions to increase the annual production capacity of its electrolyzer manufacturing plant from 300 MW to 1,000 MW.

Independent renewable energy producer Juniper Green Energy‘s subsidiary, Juniper Green Sigma Eight, signed a power purchase agreement with TATA Power Company for a 70 MW firm and dispatchable renewable energy project. Under this PPA, Juniper Green Energy will develop a renewable energy project in Maharashtra, comprising a mix of solar, wind, and battery energy storage systems (BESS). The project will have a renewable energy capacity of around 180 MWp and a BESS of around 280 MWh. The supply of power from this project is scheduled to commence on September 22, 2027.

Vijayawada-based infrastructure development company PVV Infra won two orders from Uttar Pradesh New and Renewable Energy Development Agency to develop a cumulative capacity of 209 MW solar projects. The projects are valued at ₹7.99 billion (~$90 million). PVV EVTech, a subsidiary of PV Infra, won 100 MW solar projects to develop projects across the state’s Baghpat and Moradabad districts. The projects will be executed in a joint venture with Nacof Oorja at an estimated project cost of ₹3.84 billion (~$43.26 million). They are expected to generate an annual revenue of ₹530 million (~$5.97 million).

The joint JV between Maharashtra Power Generation Company and SJVN targeted developing 735 MW of renewable energy projects in the first phase of a 5 GW clean energy push in the state. In the first phase, the JV will develop the 125 MW Ghatghar Phase 2 pumped storage project, the 105 MW Irai floating solar project, and 505 MW of floating solar projects on reservoirs. The Maharashtra government approved a proposal last month to establish a JV with SJVN for developing 5 GW of renewable energy projects in the state.

China-based solar module manufacturer SoleFiori is setting up a 6 GW heterojunction (HJT) module manufacturing facility in Saudi Arabia. The company signed an agreement with its Saudi partners in Beijing recently. The new manufacturing facility will use SoleFiori’s existing technologies and production processes to focus on research, development, and manufacture of HJT modules. SoleFiori claimed its HJT technology is recognized for minimal power degradation in high temperatures and high bifaciality, making it an ideal choice for photovoltaic applications in Saudi Arabia and across the Middle East and North Africa.
