Aside from stepped-up measures to promote the development of solar and wind energy, the document calls for promoting the development of hydropower where conditions permit and developing nuclear power in an "active" but "safe and orderly" manner.

The capacity of hydropower station for pumped storage is expected to increase by roughly 40 million kilowatts during the 14th Five-Year Plan period and by the same amount again during the 15th Five-Year Plan (2026-30) period, it said.

To address the intermittent problem of renewable energy, the document said the country will work out medium- and long-term planning for developing pumped storage and improve the policy mechanisms to boost the development. Pumped storage is a means of regenerating unused electricity potential.

By 2030, the pumped storage capacity of Chinese hydropower stations will reach some 120 million kilowatts, it said.

The plan details specific transformation actions for different sectors.
