- System size: 95 MW / 426 MWh
- Duration: about 4.5 hours
- Battery hardware: SolBank 3.0, 5 MWh packs (LFP)
- Timeline: install H2 2027, operation early 2028
e-STORAGE, the grid-battery unit of Canadian Solar, signed a supply agreement on June 25, 2026 to deliver a 95 MW / 426 MWh battery energy storage system for an electric utility in Florida, its first project in the state. Installation is planned for the second half of 2027, with commercial operation targeted for early 2028. The utility offtaker and project site were not disclosed, and no contract value was given.
What the deal covers
e-STORAGE will supply a complete, integrated system: its SolBank 3.0 packs, rated at 5 MWh each, plus the power conversion systems and energy management software. The lithium iron phosphate cells are produced at Canadian Solar’s own factories, giving the company a cell-to-system supply chain that few pure integrators control. At 426 MWh against 95 MW, the system runs about 4.5 hours, long enough to shift solar output into Florida’s evening demand peak rather than provide only short-duration frequency response.
Why It Matters
Florida has trailed Texas and California in grid-scale storage, and its utilities have historically leaned on natural gas for peaking capacity. A 4.5-hour battery procured by a Florida utility signals a shift toward multi-hour storage to absorb the state’s fast-growing solar output and cover summer evening peaks. For e-STORAGE, the agreement marks entry into a market where storage has been bought piecemeal, adding a vertically integrated supplier that controls cells, packs and controls in one stack. The undisclosed offtaker and absent dollar figure leave the project’s economics unverifiable for now; the concrete commitments are the 95 MW capacity, the SolBank hardware, and the early-2028 operation date.
Critical Perspective
e-STORAGE signed a supply deal for a 95 MW / 426 MWh battery, about 4.5 hours of duration, and called it a foothold in Florida, but disclosed neither the utility buyer nor the contract value. A supply agreement without a named offtaker or a price is a hardware order, not a financed and interconnected project, and Florida’s storage build-out so far has come almost entirely from utilities constructing their own assets rather than buying from merchant integrators. Florida Power and Light’s Manatee Energy Storage Center, roughly 409 MW / 900 MWh when it came online in 2021, was built by the utility itself and remains the state’s defining storage project. If the buyer and the dollar figure both stay hidden, does a single 95 MW order represent real entry into Florida, or a rounding error next to the gigawatts NextEra is already installing on its own?
