Yitong Century: Plans to invest approximately 430 million yuan to build the first phase of the ESS power station project

Low-price hours and seasonal swings are becoming as important as generation volume in solar project economics.

During the week, cooling weather weakened air-conditioning demand across northern China, while Guangdong remained relatively warm early in the week before rainfall increased under the influence of the tropical depression. This created diverging load conditions across regions. At the same time, rising coal and LNG prices strengthened the cost floor for conventional generation.

Shandong has recently moved to adjust its spot-market price floors, industrial and commercial time-of-use tariffs, and operating rules for energy storage co-located with renewable energy stations. Although the three policies target differently, they all address the same challenge.The policies do not mark a return to mandatory storage requirements, but they do increase the downside price exposure of non-mechanism PV volumes and strengthen the need to shift electricity across time.
