Govt. Allows Sale of T-GNA Curtailed Renewable Power Through Co-Located BESS

The Ministry of Power has allowed renewable energy developers to store electricity curtailed under Temporary General Network Access (T-GNA) in voluntarily deployed, co located Battery Energy Storage Systems (BESS) and sell the recovered power in the open market.

The directive permits renewable energy projects awarded under standard bidding guidelines to use T-GNA curtailed electricity for charging additional co located storage systems. These BESS assets do not need to be part of the project's original Power Purchase Agreement (PPA) or Power Sale Agreement (PSA).

After storing the curtailed renewable electricity, developers can sell the recovered energy to any buyer through power exchanges or bilateral arrangements. The move provides developers with an additional route to monetise electricity that would otherwise be lost because of transmission constraints.

The directive follows a July 22, 2026 memorandum from the Ministry of New and Renewable Energy (MNRE), issued after renewable energy developers sought clarification on the use and commercial sale of power curtailed under T-GNA.

Importantly, developers will not be required to obtain a No Objection Certificate (NOC) from intermediary procurers or end procurers before storing and selling the curtailed electricity.

The Ministry's decision is expected to improve utilisation of renewable generation and storage assets while reducing energy wastage caused by grid constraints. It could also encourage developers to deploy additional co located BESS capacity and create new market based storage models.

By allowing curtailed renewable power to be stored and sold separately from contracted supply arrangements, the policy provides developers with greater flexibility to utilise surplus clean electricity and potentially generate additional revenue.
