An early-stage hybrid call from one of India’s most active storage buyers, tracked as part of our tender tracker.
Maharashtra floating solar with battery storage

EOI
A 170 MW floating array with co-located batteries — still at the expression-of-interest stage, so the storage block is not yet sized in public.
Mercom India ↗What it means
An expression of interest is not a tender. It comes earlier: the buyer describes the project shape and asks the market who would build it and on what terms, then uses the responses to write the actual bid documents. For developers, the value of responding is influence over specifications that are still movable — including how large the battery ends up being, which this call has not yet fixed in public.
Floating solar is a natural fit for storage. Reservoir sites are chosen for water surface rather than for grid strength, so the evacuation connection is often the constraint; a co-located battery lets a larger array share a smaller interconnection by clipping midday output into the evening. That is the standard solar-plus-storage case.
Maharashtra continues to buy storage in two directions at once — bundled with new generation here, and on its own through the headline 4 GWh battery tender. This is also the state’s second floating-solar-with-storage call we have briefed, after the smaller 59 MW project. The state framework behind both is in our Maharashtra BESS policy explainer.
