In order to gather both qualitative and quantitative insights, supply-side and demand-side stakeholders were interviewed during the primary research process. CEOs, CTOs of energy storage, heads of grid solutions, regulatory affairs directors, and commercial leaders from manufacturers of energy storage technologies, independent power producers, grid-scale integrators, and ESCOs (Energy Service Companies) were examples of supply-side sources. Chief sustainability officers, energy procurement managers, grid operators, utility executives, facility managers from commercial and industrial businesses, and developers of renewable energy projects from utilities, independent system operators, and microgrid developers were examples of demand-side suppliers. Primary research verified project pipeline timings, validated market segmentation across service models (Energy-Only, Capacity-Only, Full-Service), and collected information on grid interconnection procedures, energy arbitrage tactics, capacity market participation, and financing arrangements.

Global market valuation was derived through revenue mapping and installed capacity analysis. The methodology included:
Identification of 50+ key stakeholders across North America, Europe, Asia-Pacific, Latin America, and Middle East & Africa
Technology mapping across lithium-ion batteries, flow batteries (vanadium redox, zinc-bromine), flywheels, supercapacitors, and pumped hydro storage systems
Service model analysis across Energy-Only, Capacity-Only, and Full-Service offerings
Analysis of reported and modeled annual revenues specific to energy storage-as-a-service portfolios
Coverage of stakeholders representing 75-80% of global market share in 2024
Extrapolation using bottom-up (installed capacity × service fee by region/technology) and top-down (ESCO and utility revenue validation) approaches to derive segment-specific valuations across utilities, commercial & industrial, and residential applications
