Changes at the policy level fundamentally constitute a redefinition of the role of energy storage. With the phasing out of mandatory storage mandates, energy storage is no longer merely an ancillary component of new energy projects; rather, it has emerged as a market entity possessing its own independent logic for investment returns. Concurrently, the pathways for independent storage facilities to participate in mechanisms such as spot markets, ancillary services, and demand response are becoming increasingly clear, leading to a diversification of revenue streams.
