Technical FAQs 4

Is China entering a new era of energy storage demand?

Mainland China accounts for most of the global energy storage demand, driven in the near term by regional requirements for new utility-scale wind and solar projects to include energy storage capacity. However, the Chinese market is entering an era of change.

How do renewables affect wholesale electricity prices?

The rapid rise of renewables, particularly wind and solar, has increased volatility in wholesale electricity markets. Daytime oversupply depresses prices — often into negative territory — while evening demand spikes have become sharper.

How will wind & solar payments work in 2025?

New policy introduced in February 2025 requires wind and solar payment mechanisms to move toward more market-based structures, where 100% of wind and solar generation is to be traded in the wholesale market with local governments left to define their own implementation details by the end of the year.

What is China's solar and wind capacity?

China’s solar and wind operating capacity has soared to 1.4 TW and now accounts for 44% of the world’s operating utility-scale solar and wind capacity, more than the combined total of the European Union, United States, and India.
