Kerala's power ministry aims to commission the Mylatti Battery Energy Storage System (BESS) by October 2026, with parallel work on a smaller Mulleria project. Minister Sunny Joseph has instructed all agencies to meet the deadlines and boost grid reliability.

Key Takeaways (मुख्य बिंदु)

  • Mylatti BESS slated for commissioning in October 2026
  • First four‑hour battery storage project of its kind in India (125 MW/500 MWh)
  • Two-phase rollout: Mylatti (125 MW) and Mulleria (15 MW)

Amid a statewide power crunch, Kerala's Electricity Minister Sunny Joseph inspected the ongoing Battery Energy Storage System (BESS) projects in Kasaragod district. The flagship 125 MW/500 MWh installation at the 220 kV Mylatti substation is targeted for commissioning on 16 October 2026, while the 15 MW/60 MWh unit at the 110 kV Mulleria substation aims for 15 October 2026. Both projects are being executed by the Kerala State Electricity Board (KSEBL) under Build‑Own‑Operate (BOO) contracts with JSW Energy and Opera Energy respectively.

Historical Background (तथ्यात्मक पृष्ठभूमि)

Battery storage in India gained momentum after the 2015 National Renewable Energy Policy emphasized grid‑scale storage to counter the intermittency of solar and wind power. Early large‑scale BESS deployments occurred in southern states in 2021, but Mylatti represents the nation’s first four‑hour, high‑capacity storage system, marking a strategic shift toward more resilient renewable integration.

Why This Matters (इसके मायने क्या हैं)

According to BozokMedia analysis, the projects will significantly enhance Kerala’s energy security by storing daytime solar surplus and discharging it during evening peaks, reducing reliance on costly imported power. The financial relief for KSEBL translates into lower tariffs for consumers and frees up state resources for other development initiatives.

For everyday citizens, the impact will be felt as fewer outages, expanded electric‑vehicle charging infrastructure, and more reliable power for agriculture, tourism, and IT sectors. With a 12‑year project life, the investment also promises long‑term industrial growth in Kasaragod.

"Effective BESS deployment is the linchpin for a stable, renewable‑rich grid," says energy analyst Dr. Anita Roy.

Did You Know?: The first four‑hour battery storage trial in India was conducted in Mumbai in 2020, but Mylatti is the first commercial‑scale implementation.

Frequently Asked Questions (अक्सर पूछे जाने वाले प्रश्न)

Q1: What is the primary function of a BESS?
A: It captures excess solar generation during the day and releases it during peak evening demand, stabilizing voltage and reducing the need for external power purchases.

Q2: How will this project affect Kerala’s electricity costs?
A: By lowering dependence on expensive imported electricity, the state expects noticeable savings, which can be passed on to consumers as reduced tariffs.
