Perinjanam panchayat in Kerala is preparing to implement a pioneering Battery Energy Storage System (BESS) to store solar generation and supply electricity during peak night hours. The pilot has received Rs 20 million (mn) in government support and will store three point one six megawatt (MW) of solar power generated every month. The initiative is described as the first panchayat-level BESS project in India.

Under the BESS model daytime solar will be stored in a lithium battery system and dispatched to the Electricity Department during high-tariff night hours. At present the department pays an average of Rs three point zero four per unit for direct solar supply and the tariff during peak demand rises to Rs seven per unit. The shift is expected to raise revenue for the panchayat and participating households.

Perinjanam has pursued decentralised solar since 2018 under the leadership of K K Sachith and now counts 860 households and more than 100 institutions as participants generating three point one six megawatt (MW) every month. The Perinjanam Cooperative Bank provided collateral-free loans to finance rooftop installations and beneficiaries repaid their loans within four years and now earn income from surplus generation. The model has been presented as an example of environmental and financial benefits from local renewable projects.

A nine point five kilowatt (kW) solar installation at the Perinjanam Government School supplies around 800 streetlights and has reduced the monthly streetlight electricity bill from Rs 90,000 to Rs 32,000. The BESS pilot is expected to strengthen the panchayat's position as a national leader in decentralised solar adoption and to create additional revenue streams for community members. Officials plan to monitor operational performance and financial outcomes as the pilot progresses.

The initiative is likely to inform similar efforts in other local governments seeking to balance daytime renewable generation with peak demand economics. Technical performance, battery lifecycle and tariff realisation will determine the replicability and scalability of this panchayat-level approach. Stakeholders emphasise community finance mechanisms and cooperative support as key enablers of wider adoption.
