The Supreme Court of India directed the Maharashtra Electricity Regulatory Commission (MERC) to review the petitions challenging the impugned multi-year tariff (MYT) within 12 weeks. In a November 17, 2025, ruling remanding the matter to the MERC, the apex court said all stakeholders must be heard before the electricity regulator takes a decision. It also said the directions issued by the Bombay High Court in the matter will continue to operate. Recently, the Bombay High Court quashed the impugned MYT order limiting power banking facilities in the state and said that the earlier MYT order, passed by MERC on March 28, 2025, will continue to be in force.
A new staff paper by the Central Electricity Regulatory Commission (CERC) suggested that grid connectivity for renewable energy projects be given only if they have signed power purchase agreements. As another option, it has been recommended that an auction regime be introduced for all connectivity allocations. These suggestions have been made in the context of 31.8 GW of renewable energy projects that have secured tentative grid connectivity in the absence of power purchase agreements (PPAs) as of June 2025. When pending applications are included, this number climbs to nearly 45.3 GW, representing a very large block of connectivity that has not yet translated into firm offtake in India’s transition pipeline.
The CERC approved tariffs of ₹5.06 (~$0.0567)/kWh and ₹5.07 (~$0.0568)/kWh for 420 MW of Solar Energy Corporation of India’s (SECI) 1,200 MW renewable energy projects with an energy storage system. The Commission also approved a trading margin of ₹0.07 (~$0.0008)/kWh, subject to a cap of ₹0.02 (~$0.0002)/kWh if SECI did not provide escrow or line-of-credit payment security.
Lineage Power, a material subsidiary of Pace Digitek, received an order worth ₹1.9 billion (~$22.33 million) from Larsen & Toubro to supply 275,825 kWh of battery energy storage systems (BESS) in 55 integrated LiFePo4 liquid cooling containers for the Bihar State Power Generation Company in Kajra, Lakhisarai district. This order is part of the 116 MW solar project integrated with a 241 MWh BESS that Larsen & Toubro won from BSPGCL in August this year. Lineage Power will execute the order by March 2026.
Ahmedabad-based integrated power transmission equipment manufacturer, Diamond Power Infrastructure, received a letter of intent to supply transmission conductors worth ₹2.76 billion (~$30.96 million) from Adani Energy Solutions for the Khavda renewable energy project. The order involves the supply of 7,668 km of AL-59 zebra conductors. The cables must be supplied by November 23, 2026. In addition to conductors, Diamond Power also manufactures cables for the power sector.
Southern Railway invited bids for installing rooftop solar systems with a cumulative capacity of 1 MW at various locations of Rameswaram station under the Madurai Division, Tamil Nadu. The rooftop solar systems will have a minimum capacity of 10 kW. The tender has specified an expected aggregate generation of 28.13 million kWh over the project billing period. The scope of work includes the designing, building, financing, and operation of the project through the renewable energy service company model. Successful bidders will be responsible for conducting detailed site surveys, supplying modules and associated electrical components, mounting structures, evacuation systems, metering arrangements, remote monitoring, and safety systems.
Power Grid Corporation of India (POWERGRID) invited bids to select a consortium partner to set up 1,000 MW/2,000 MWh of standalone BESS across seven substations in Andhra Pradesh. Bids must be submitted by November 27, 2025. Bids will be opened on the same day. This tender is a pre-bid tie-up up and its award is contingent on POWERGRID winning the upstream tender floated by Andhra Pradesh Power Transmission Corporation (APTRANSCO). The scope of work involves setting up the BESS, including the battery system, power conversion system, and transformers, and interconnection with the 33 kV bus developed by APTRANSCO.
Kolkata-based solar module manufacturer Vikram Solar commissioned a 5 GW solar module manufacturing facility in Vallam, Tamil Nadu, increasing its total production capacity to 9.5 GW. The facility covers 27,000 square meters and has been designed as a fully automated facility to ensure productivity, consistency in quality, and supply reliability. The facility utilizes advanced TOPCon technology and is designed to support an upgrade to heterojunction technology. It can produce modules across M10, G12, and G12R formats.
Australia-based clean energy solutions company Hydro Tasmania invited expressions of interest for new wind and solar developments across Tasmania to deliver up to 1,500 GWh of electricity annually, aiming to increase the state’s renewable energy supply to the electricity grid. Proposals must be submitted by December 5, 2025. The selected projects must be operational within the next five to six years, aligning with forecasted increases in demand. Hydro Tasmania has demonstrated support for large-scale solar investment. In 2024, the utility agreed to purchase electricity generated from a proposed 288 MW solar project in the Northern Midlands.
