According to the latest IndexBox report on the global Concentrated Solar Power Csp market, the market enters 2026 with broader demand fundamentals, more disciplined procurement behavior, and a more regionally diversified supply architecture.
The global Concentrated Solar Power (CSP) market is entering a strategic re-rating as utilities and grid operators prioritize dispatchable, long-duration renewable capacity over intermittent generation alone. CSP’s integrated thermal energy storage (TES) allows solar energy to be shifted into evening peaks and overnight periods, providing firm capacity, grid inertia, and ancillary services that are increasingly valuable in high-renewable-penetration systems. Deployment is concentrated in sunbelt regions with high direct normal irradiance (DNI) and urgent grid-stability needs, while manufacturing and component expertise remain clustered in a few industrial hubs.
The competitive landscape is consolidating around vertically integrated developers and specialized EPC-integrators capable of managing multi-year project execution and performance risk. Project economics are shifting from levelized cost of energy (LCOE) toward levelized cost of storage (LCOS), with value stacking through capacity payments, ancillary service markets, and clean firm power contracts. This report provides a structured, commercially grounded analysis of the CSP market, covering historical development from 2012 to 2025 and forward-looking scenarios through 2035, segmented by technology, end-use sector, storage architecture, and geography.
The baseline scenario for the global CSP market through 2035 assumes continued policy support for dispatchable renewables in key sunbelt markets, gradual cost reduction in solar field and thermal storage components, and sustained bankability for integrated CSP-TES projects. Under this scenario, deployment is expected to grow at a moderate single-digit CAGR, with capacity additions concentrated in the Middle East and Africa, Asia-Pacific, and selected Latin American markets.
The value proposition of CSP is increasingly tied to its storage duration and grid-support capabilities rather than pure generation cost, supporting demand from utilities and independent power producers seeking firm capacity. Hybrid CSP-PV configurations are expected to gain share, optimizing land use and grid connections while improving project economics. Supply chain constraints, particularly in specialized receiver tubes and molten-salt components, may temper growth rates in the near term but are expected to ease as manufacturing capacity expands.
The market index (2025=100) is projected to reach approximately 145 by 2035, reflecting cumulative growth of about 45% over the forecast period. Key uncertainties include the pace of cost reduction in competing battery storage, the availability of concessional financing, and the evolution of capacity remuneration mechanisms in emerging markets.
Electric utilities and independent power producers are the primary buyers of CSP capacity, driven by the need to meet renewable portfolio standards while maintaining grid reliability. As variable renewable penetration increases, utilities require dispatchable generation that can be scheduled to match demand peaks and provide ancillary services. CSP with thermal energy storage offers a unique combination of renewable generation and long-duration storage, enabling utilities to contract for firm capacity rather than intermittent energy. Through 2035, demand from this segment is expected to grow as more utilities seek clean firm power contracts and capacity payments to replace retiring thermal generation.
Key demand indicators include renewable portfolio standards with dispatchability credits, capacity auction outcomes, and the share of variable renewables in utility generation mixes. The segment’s growth is also supported by hybrid CSP-PV projects that optimize land and grid connection use. Current trend: Growing demand for firm capacity and dispatchable renewable power.

Representative participants: ACWA Power, Abengoa, and Engie.
CSP is finding niche applications in mining and remote communities where reliable, dispatchable power is needed and grid connection is limited or expensive. In mining, CSP can provide power for operations and processing, often integrated with thermal storage to ensure continuous supply. For remote communities, CSP can offer a sustainable alternative to diesel generation, reducing fuel costs and emissions. The segment’s demand is driven by the need for reliable power in off-grid locations, corporate sustainability targets in the mining sector, and government programs to electrify remote areas.
Through 2035, demand from this segment is expected to grow modestly as more mining companies seek to decarbonize operations and as remote electrification programs expand. Key indicators include mining activity in sunbelt regions and off-grid electrification budgets. Current trend: Niche demand for off-grid and remote power applications.
Major trends: Growing mining sector focus on decarbonization, Rising diesel costs driving interest in renewable alternatives, Government programs for remote community electrification, and Integration of CSP with thermal storage for continuous off-grid power.
