1 MWh BESS Solution

CLN Energy’s Microgrid Solution—also known as a distributed energy island system—seamlessly integrates local power generation, energy storage, photovoltaic (PV) systems, and smart load control into a unified, self-reliant power network. Designed for flexibility, it can operate independently or in sync with the main grid. Ideal for remote areas, islands, and off-grid locations, this 5.015 MWh Battery Energy Storage System (BESS) delivers high-capacity, stable, and scalable power. It ensures energy availability, reduces reliance on fossil fuels, and enables sustainable, grid-independent operations.

Built in India

Manufactured at CLN Energy's own plant at Sector 140, Noida — the plant is also the registered office, and the company is listed on the BSE SME platform under scrip 544347. Cells are lithium iron phosphate throughout.

That matters at the two moments location usually does: when something needs looking at, and when a warranty has to be honoured. Packs in service include 22,864 across BSNL's telecom network, backup at RailTel's Pondicherry command control centre, and signalling backup for Southern Railway — each on its own project page with the real configuration.
