Should energy storage power plants be exempt from peak shaving?
In addition, the new energy storage power plants and pumped storage power plants enjoy higher compensation standards and call priorities for peak shaving, and the exemption of wind power and PV power in auxiliary services for peak shaving also goes against the fairness and justice of the market.
Why is solar power a problem?
However, the root causes of the problem are a mismatch between the development of wind power and solar power and the current power system, immature technology, difficulty in absorbing wind and solar power across regions, and a lack of large-scale capability for absorbing wind and solar power on the demand side.
How much subsidy should PV energy storage facilities be paid?
It specifies that energy storage facilities constructed synchronously with newly installed PV power generation should be paid a subsidy within 600 euro. In addition, the subsidy paid to energy storage facilities added to existing PV power generation should be within 660 euro/kW. What's more, price policies for PSS are relatively perfect in the EU.
