What This Article Covers

1.Kerala State Electricity Board (KSEB) has set October 2026 as Commercial Operation Date for five Battery Energy Storage System (BESS) projects with a combined capacity of 250 MW/940 MWh.

2.A sixth project at Brahmapuram (250MW/500MWh) is approved with Viability Gap Funding (VGF) from the central Power System Development Fund (PSDF).

3.The move aims to solve operational challenges like expensive power purchases during non-solar hours and 'surrender' of contracted power due to daytime solar injection.

The Big Picture
Prelims · HighMains · Medium

Kerala is addressing its grid instability caused by daytime solar surplus by commissioning five Battery Energy Storage Systems (BESS) by October 2026. This state-level initiative, supported by central funding, is a critical case study for energy storage solutions in India's renewable energy transition, highly relevant for UPSC GS3 and state PSC exams.
