A review of the energy storage electricity price mechanism policy

How do electricity price mechanisms affect the operation and investment models?

Operation and Investment Modes under the Influence of Electricity Price Mechanisms In the process of electricity market development, changes in electricity price mechanisms reflect the evolution of market competition and related mechanisms, directly impacting the operation and investment models of energy storage.

Are market mechanisms conducive to cost-sharing of energy storage?

However, the current market mechanisms are not conducive to the proper cost-sharing of energy storage and are difficult to support the large-scale investment and operation of future new energy storage projects in China.

Can energy storage recover its own value?

The time-of-use electricity price in the domestic market is often determined by the power grid, and the price difference between peak and valley hours is not large. Energy storage cannot fully recover its own value by arbitrage income in the electric energy market.

How to marketize energy storage transactions?

As the capacity market mechanism matures, it is advisable to gradually promote the marketization of energy storage transactions. Through market competition, capacity compensation prices can be formed, and ultimately, these costs can be distributed among all users through transmission and distribution tariffs. 5. Conclusion

Should energy storage be integrated into power system models?

Integrating energy storage within power system models offers the potential to enhance operational cost-effectiveness, scheduling efficiency, environmental outcomes, and the integration of renewable energy sources.

What is the external value of energy storage in China?

For China’s most widely used dual-pricing system, the external value of energy storage in the market can be regarded as reflecting and radiating value through the electricity market and capacity market, where the capacity market includes some functions of the ancillary services market.
