Battery energy storage, engineered end to end
From grid-forming island microgrids to behind-the-meter BESS, PEC designs, integrates, and commissions battery energy storage with the PCS and EMS to match — then maintains it for the long run.
From design to commissioning
We size the battery, PCS, and enclosure to your load profile, duty cycle, and site conditions — not a catalogue default.
The battery, power-conversion system, and energy-management system work together as one — the EMS dispatches power to match the site's role.
Build a microgrid that holds its own voltage and frequency and keeps running when there is no main grid to lean on — proven on real island sites.
Pair storage with PV, wind, or diesel to reduce output swings, shift energy to peak hours, and cut fuel — from a single site to a utility plant.
From remote islands to grid-scale
Grid-forming storage that keeps islands and off-grid sites powered when there is no main grid behind them.
Firm up PV and wind output, shift surplus to peak, and reduce curtailment for RE developers and operators.
Cut demand charges, back up critical loads, and get more out of on-site PV — integrated with your existing plant.
Larger BESS for smart-grid, net-zero, and utility projects — engineered to each site's role and duty.
