The Tamil Nadu Electricity Regulatory Commission (TNERC) has approved Tamil Nadu Green Energy Corporation Ltd. (TNGECL)’s plan to procure 1,000 MWh of battery energy storage systems (BESS), marking one of India’s largest state-led storage deployments. The decision, issued on December 4, 2025, authorizes long-term procurement under a 12-year build–own–operate framework, supported by the Union Government’s Viability Gap Funding (VGF) program. Project Overview Capacity: 500 MW a

Uttarakhand’s amendment formally brings Battery Energy Storage Systems (BESS) into renewable tariff rules, setting useful life at 12 years, a net BESS tariff of ₹5.78/kWh, and new commissioning, depreciation, and metering norms—effective from 27 November 2025. The Uttarakhand Electricity Regulatory Commission (UERC) issued the second amendment to its renewable tariff regulations to explicitly include BESS alongside solar and small hydro, renaming the principal regulation and

The Central Electricity Regulatory Commission (CERC) has released the Draft Terms and Conditions of Tariff (Second Amendment), 2025 , marking a significant evolution in India’s transmission tariff framework. Building on the 2019 regulations and the 2023 first amendment, the new draft introduces provisions that mainstream energy storage systems (ESS) into tariff determination, particularly when linked to thermal Inter-State Transmission Systems (ISTS). Earlier regulations had

The Supreme Court has remanded the Maharashtra MYT review back to MERC and ordered a fresh decision within 12 weeks, keeping existing tariffs in force while mandating stakeholder consultation — a move that could reshape developer economics, consumer bills, and the pace of storage and renewable integration in the state. The dispute centers on MERC’s Multi‑Year Tariff (MYT) order  and a subsequent review order that was challenged in court. The Supreme Court’s November ruling re

CERC’s staff paper proposes converting, substituting, or auctioning idle LOA‑based grid connectivity to ensure efficient transmission use. These reforms aim to accelerate India’s 500 GW green energy integration and support the net‑zero pathway by enforcing discipline, transparency, and locational efficiency. The Central Electricity Regulatory Commission (CERC) staff paper (SP‑251125) addresses a critical bottleneck in India’s Renewable Energy (RE) integration: connectivity gr
