Type Editorial supply-chain classification based on the sourced portfolio: system integrator, cell manufacturer, non-lithium or mechanical storage developer, power equipment group, or software and controls supplier.

Integrator 1

Chemistry Main storage chemistry of the flagship product. LFP is lithium iron phosphate; NMC is lithium nickel manganese cobalt oxide; LTO is lithium titanate. Mechanical covers gravity, compressed air and CO2 stores. Mixed means the vendor sells more than one chemistry at scale.

LFP 1

Flagship product The vendor's main grid-scale or commercial storage product line, as the vendor names it.

Deployed GWh Cumulative storage the vendor says it has deployed, delivered or shipped, in GWh, at the date of the cited source. Shipments and installed capacity differ; the spec notes say which one the vendor reports.

Not published

Deployed + contracted GWh Deployed plus contracted or awarded storage (backlog under contract) in GWh, as the vendor states it. Blank when the vendor publishes no contracted figure.

Not published

Cycle life cycles Rated cycle life of the flagship cell or system as the vendor publishes it. Test conditions (temperature, depth of discharge, end-of-life capacity) differ by vendor and are in the spec notes.

Not published

Warranty years Longest standard product or performance warranty term the vendor publishes for the flagship system, in years.
