Solar energy mandatory storage
Previously, in February 2025, the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) issued Document No. 136, explicitly stating that energy storage configuration should not be a prerequisite for the approval of new energy projects, ending the "mandatory energy storage" policy that had been in place since Qinghai first introduced it in 2017.

FAQS about Solar energy mandatory storage
How can solar energy be stored?
Solar energy can be stored when it's produced and made available when you need it, allowing you to use more renewable energy and be less reliant on other power sources. Superior Solar is a Tesla Energy Certified Installer and our team are accredited in the latest battery storage technology, from Tesla Powerwall to LG Chem batteries.
How much solar storage do I Need?
• Properly sized systems will meet the full load on the best solar day of the year. • Approximately 1–2 gal of storage should be provided per square foot of collector. • 1 ft2 of collector heats about 1 gal per day of service water at 44° latitude.
How will the energy storage mandate impact China?
S&P Global estimates that the storage mandate has driven between 50 and 75% of domestic demand. With China accounting for around 56% of the global energy storage demand in 2024, the impact of such a policy change will be massive.
Is the energy storage mandate a big change?
This is a big change towards rationalization of renewables but hidden within that is a removal of the energy storage mandate,” George Hilton, research and analysis manager at S&P Global, tells ESS News. S&P Global estimates that the storage mandate has driven between 50 and 75% of domestic demand.
Will battery storage reverberate through global supply chain?
S&P Global expects the move to reverberate through the global battery storage supply chain, further driving down prices already at historic lows. From ESS News New renewable energy plants in China will no longer be required to build storage in order to secure development rights and grid connection.
How will China's energy storage policy affect global demand?
“China was on-track to install over 60% of all utility scale storage globally in 2025 and so in the absence of further policy changes, about 45% of global demand has just been wiped away,” Hilton says. The ripple effect on the global demand-supply balance will involve further downward pressure on energy storage prices.
