What is SECI's 100 MW solar and 120 MWh battery storage project?

SECI has invited bids for a project management unit to support a 100 MW solar project paired with 120 MWh of battery energy storage, reported by Mercom India on 6 August 2026. The PMU call covers project supervision; the battery's power rating, and therefore its discharge duration, is not stated.

SECI is staffing up the supervision layer for a 100 MW solar plant with 120 MWh of batteries — a sign the project itself is heading into execution.

What it means

The call itself is for a project management unit — the team that supervises engineering, procurement and construction on the owner’s behalf — rather than for the battery supply. That is a useful signal in its own right: a buyer appoints a PMU when a project is close enough to execution to need day-to-day oversight.

On the technical side, 120 MWh against 100 MW of solar is a modest storage block relative to the plant, the shape used to shift a slice of midday generation into the evening rather than to firm the whole output. Because the battery’s power rating is not stated, the discharge duration is unknown — the number our two-hour versus four-hour explainer shows to be decisive for both design and cost. The pairing follows the same logic as the solar-plus-storage systems we build, under the central procurement rules set out in our India BESS policy overview.
