A comprehensive review of the impacts of energy storage on power
Energy storage can affect market prices by reducing price volatility and mitigating the impact of renewable energy intermittency on the power system. For example, energy storage can help to smooth out the variability of wind and solar power by storing excess electricity during periods of low demand and discharging when demand is high.

Under the "pay-for-performance" model, resources must deliver on demand during system emergencies or owe a
Renewable electricity – Renewables 2022 – Analysis
The global energy crisis is pushing the accelerator on renewable energy expansion. Global renewable capacity is expected to increase by almost 2 400 GW (almost 75%) between 2022 and 2027 in the IEA main-case forecast, equal to the entire installed power capacity of the People''s Republic of China (hereafter "China").
Capacity Price
Capacity Market (CM) is designed to provide long-term stability and security in the power system by preventing a deficit of generation capacities. Hence it almost fully eliminates electricity price volatility. By selling capacity, a generator assumes it as an obligation and gets paid for it.

Value of energy storage aggregation to the electricity system
Decentralized coordination always leads to greater mean prices compared to centralized coordination, ranging between 25 and 34 £ /MWh. Centralized coordination benefits from more resources devolved to smoothing system demand and may lower electricity prices by 4–7%, subject to total storage capacity. Table 3.

They introduced auctions whereby the bidder with the lowest electricity price would win the development rights for a certain location. Fierce competition ensued, with prices dropping by as much as 50 to 80 percent from 2015 to 2018. The merchant risk undertaken by developers remained limited—but this is changing rapidly.
