India generated over 38.3 billion units (BU) of solar power in the third quarter (Q3) of 2025, representing a 20.4% year-over-year increase. Solar generation decreased by 11% quarter-over-quarter (QoQ) from 43 BU. Rajasthan, Tamil Nadu, and Gujarat led the solar power generation during the quarter. Rajasthan topped the list with 14.3 BU, from 15.9 BU in Q2 2025. Tamil Nadu was second at 4.9 BU, increasing from 4.7 BU in the previous quarter. Gujarat ranked third with 4.8 BU compared to 5.9 BU in Q2 2025. Solar generation in Rajasthan and Gujarat dropped by 9.7% and 18.5% QoQ, respectively, due to prolonged monsoons. In Tamil Nadu, however, solar generation increased by 4.7% QoQ.
The Delhi High Court directed a wind energy developer to approach the Central Electricity Regulatory Commission (CERC) to settle its dispute with the Solar Energy Corporation of India (SECI) over the payment of liquidated damages. The High Court said that according to Section 79 (1) (f) of the Electricity Act, 2003, the CERC was vested with adjudicatory powers to settle disputes between power generators and distributors, as well as referral powers for disputes outside the CERC’s purview. It dismissed ReNew Wind Energy’s plea seeking an interim injunction against SECI seeking liquidated damages for not meeting the minimum energy requirements during the financial year 2025 as per the power purchase agreement.
The Gujarat Electricity Regulatory Commission approved tariffs of ₹280,000 (~$3,160.22)/MW/month and ₹285,600 (~$3,223.42)/MW/month for Gujarat Urja Vikas Nigam’s (GUVNL) 500 MW/1,000 MWh standalone battery energy storage system (BESS) projects in Gujarat. The BESS projects will be set up at Gujarat Energy Transmission Corporation substations. The petitioner, GUVNL, issued a tender for 500 MW/1,000 MWh standalone BESS in Gujarat in January 2025. It received 10 bids for a capacity of 2,180 MW/4,360 MWh. Solarworld Energy Solutions and H.G. Infra Engineering were selected after the e-reverse auction, securing 200 MW/400 MWh at a tariff of ₹280,000 (~$3,288.31)/MW/month and 300 MW/600 MWh at a tariff of ₹285,600 (~$3,345.08)/MW/month, respectively.
The Rajasthan Electricity Regulatory Commission (RERC) approved the levy of Parallel Operation Charges (POC) on co-located captive power projects (CPPs). The Commission has set the charges at ₹27.23 (~$0.30)/kVA/month of installed capacity for conventional CPPs and ₹11.90 (~$0.13)/kVA/month for renewable energy CPPs. For hybrid plants, the charges will be applied proportionally based on the share of conventional and renewable components. RERC first introduced POC in 2020, at a uniform rate of ₹20 (~$0.22)/kVA/month for all CPP consumers.
GERC rejected Gensol Engineering’s plea to allow its wholly owned special purpose vehicle, Gensol Green Energy, to execute the power purchase agreement (PPA) with Paschim Gujarat Vij Company. The order came as part of GERC’s approval of tariffs for 125 solar power projects with a combined capacity of 276 MW under the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) -C program. While granting tariff adoption for the projects, the Commission clarified that Gensol must adhere to the tender terms and conditions that require the original bidder to execute the PPA directly.

The European Commission announced a total of €2.9 billion (~$3.34 billion) in funding to 61 net-zero technology projects from its Innovation Fund. The funding utilizes revenues from the EU Emissions Trading System. The Commission stated that the initiative will focus on energy-intensive industries, net-zero mobility and buildings, industrial carbon management, renewable energy and energy storage, as well as cleantech manufacturing. The grants follow the first call for net-zero technologies (IF24 Call), which was launched in December 2024. The IF24 Call aims to enhance Europe’s technological leadership and accelerate the deployment of innovative decarbonization solutions.
