If wind or solar generation exceeds the region''s hydroelectric capacity, then some additional source of energy is needed. Many renewable energy sources (notably solar and wind) produce variable power. [97] Storage systems can level out the imbalances between supply and demand that this causes.
One such policy change took place in 2022 with the passage of Assembly Bill 2625, which amended zoning laws to open pathways for easier siting of energy storage projects. Prior to the bill''s passage, the approval process in California required that any land being used for energy storage be subdivided under California''s Subdivision Map Act ...
focus on battery storage, and the role that energy storage plays in the renewable energy sector. It also describes a typical project finance structure used to finance energy storage projects and highlights the key issues investors and financiers should consider when financing an energy storage project. Scope of this note
