The financial backbone of energy storage power stations is the initial capital investment required for construction and equipment procurement. Depending on the technology utilized, costs can range significantly. . To accurately reflect the changing cost of new electric power generators in the Annual Energy Outlook 2025 (AEO2025), EIA commissioned Sargent & Lundy (S&L) to evaluate the overnight capital cost and performance characteristics for 19 electric generator types. Their ability to maximize energy efficiency and deliver environmental benefits makes them essential in the clean energy transition. However, it's crucial for investors to assess the financial viability of these stations. 3% CAGR through 2030, reaching $435 billion.

All other planned energy storage projects reported to EIA in various stages of development are BESS projects and have a combined total nameplate power capacity additions of 22,255 MW planned for installation in 2023 through 2026. About 13,881 MW of that planned capacity is co-located with solar photovoltaic generators.
The capital cost breakdown for the various reactor types was not provided in the report, nor were the construction completion dates, but construction of all reference projects commenced ten or more years ago.
The final annual expense is the land lease. Solar PV projects typically rent, rather than purchase, the land for the project; therefore, it is an operating expense and not a capital cost.
These expenses may include water consumption, waste and wastewater discharge, chemicals such as selective catalytic reduction ammonia, and consumables including lubricants and calibration gas. Because these costs are generation dependent, the values are levelized by the cost per unit of energy generation and presented in $/MWh.
