The Rajasthan Electricity Regulatory Commission proposed an amendment that mandates energy storage systems (ESS) for all new renewable energy projects, except for hydroelectric power projects, with an installed capacity of more than 5 MW. Such projects must install at least ESS for 5% of the renewable energy capacity (at least 2 hours of storage). The Commission has invited comments from stakeholders before September 29, 2025. The state transmission utility will serve as the nodal agency to process bilateral long-term and medium-term green energy open access applications at the intrastate level. The state load dispatch centre will process all short-term green energy open access applications.

Prime Minister Narendra Modi launched a slew of renewable energy projects with a total capacity of 2,458 MW across the country. The projects for which the Prime Minister laid the foundation stone include Avaada’s 1,560 MW solar plus 2,500 MWh battery energy storage system (BESS) project spans 4,000 acres. The project will enable the delivery of solar power beyond solar hours by storing it in a BESS. Both projects utilize Avaada Electro’s Approved List of Models and Manufacturers-certified TOPCon N-Type bifacial solar modules. Together, these two projects represent a combined investment of more than ₹92 billion (~$1.04 billion).

The Gujarat Electricity Regulatory Commission increased the additional surcharge for open access consumers by ₹0.18/kWh (~$0.002)/kWh. The additional surcharge is ₹1 (~$0.011)/kWh from October 1, 2025, to March 31, 2026, compared to ₹0.82 (~$0.0096)/kWh that was prevalent from April 1, 2025, to September 30, 2025. The additional surcharge was ₹0.93 (~$0.01)/kWh from October 1, 2024, to March 31, 2025. The additional surcharge will apply to consumers of the four state-owned distribution companies — Dakshin Gujarat Vij Company, Madhya Gujarat Vij Company, Paschim Gujarat Vij Company, and Uttar Gujarat Vij Company — who procure electricity through open access from sources other than their respective distribution companies.

The Assam Electricity Regulatory Commission approved a ceiling tariff of ₹4.37 (~$0.049)/kWh for rooftop solar projects to be implemented on government buildings in Assam under the Renewable Energy Service Company model, as part of the PM Surya Ghar: Muft Bijli Yojana. The order was issued in response to a petition filed by Assam Power Distribution Company (APDCL). APDCL sought approval for a ceiling tariff to select developers through a tariff-based competitive bidding process to install rooftop solar systems on government buildings. In its petition, APDCL highlighted that the Ministry of New and Renewable Energy had notified a methodology for determining per-unit electricity charges for rooftop solar on government buildings. Based on parameters such as capacity utilization factor (CUF) and cost inputs, APDCL proposed a ceiling tariff of ₹5.42 (~$0.061)/kWh, calculated at a CUF of 13.5%.

Singareni Collieries Company (SCCL) floated two tenders to set up 11,300 kW of ground-mounted and rooftop solar projects. Selected bidders also must provide 10 years of comprehensive operation and maintenance services. Bids must be submitted by October 8, 2025. The approximate work order value for setting up 9,800 kW of ground-mounted and rooftop solar projects in identified vacant locations of SCCL is ₹540 million (~$6.09 million). Bidders must furnish an earnest money deposit of ₹5.4 million (~$60,869).

Gujarat-based solar module manufacturer PIXON is expanding the capacity of its 1 GW solar module manufacturing facility at Rajkot by 800 MW. The facility manufactures Tunnel Oxide Passivated Contact and Heterojunction solar modules. The expanded capacity will be commissioned by November 2025. The facility features fully automated, AI-optimized production lines with a capacity to expand up to 3 GW for solar modules and 3 GW for encapsulant film manufacturing. Both the module and encapsulant film manufacturing lines are located in the same facility.

NTPC commissioned 167 MW out of a total 245 MW solar capacity at its Nokh Solar project in Rajasthan (CPSU Program Phase-II, Tranche -III), 25 MW out of 37.5 MW (solar) in Bhuj, Gujarat, and 9.9 MW out of a total 92.4 MW capacity at its wind energy project in the same location. The wind capacity was commissioned by NTPC’s subsidiary, NTPC Green Energy. The solar capacity additions will increase NTPC’s overall installed and commercial capacity on a standalone and group basis to 60,705 MW and 83,888 MW, respectively.

Solar module manufacturer Waaree Energies stated that it will cooperate with U.S. authorities, who have launched an investigation into alleged duty evasion when importing merchandise into the country. In a communication to the stock exchanges about reports that the U.S. Customs and Border Protection has launched a probe into alleged evasion of tariffs by Waaree Solar Americas on Chinese-made solar cells and modules, labeling them as made in India, Waaree said that it was a responsible corporate citizen and was abiding by all the laws in the countries in which it operates. U.S. Customs said there was reasonable suspicion that Waaree had failed to label some of the imported components as subject to antidumping and countervailing duties that the country has been imposing on solar cells and modules made in China and a few South Asian nations.

Power Grid Corporation of India acquired Davanagere Power Transmission, a special purpose vehicle to establish a transmission system strengthening project at Davanagere, Karnataka, for the integration of renewable energy. Davanagere Power Transmission was incorporated on June 26, 2025, by REC Power Development and Consultancy (RECPDCL). RECPDCL had floated the tender to establish an interstate transmission system in Davanagere and Chitradurga, Karnataka, to integrate renewable energy generation.

Australia announced the results of the auction under Tender 3 for dispatchable power as part of the Capacity Investment Scheme (CIS) with the successful battery energy storage projects expected to deliver 4.13 GW (approximately 15.37 GWh) of capacity. The dispatched power will be added to the National Electricity Market. The tender selected 16 large-scale battery projects across the country. The CIS program aims to develop renewable generation and firming projects to deliver cheaper, cleaner, and more reliable energy for homes and businesses while coal is being phased out. Through this program, the Australian government plans to deliver 82% or 40 GW of renewable energy capacity nationwide by 2030.
