EASTERN China’s Shandong, the country’s top province for solar power, will increase payments for battery storage plants to incentivize investment in the technology to provide clean electricity around the clock. Shandong will start giving battery storage systems so-called capacity payments for being available to help balance the grid, in addition to the rates they receive for selling power, according to a policy paper published by the local government Monday. Shandong wants to boost its storage ratio to 30% of its solar capacity, from current levels of around 7%. Skyrocketing installations of solar panels in China are starting to run up against grid resistance in some parts of the country, as too much electricity is being generated in the middle of the day and not enough during peak evening hours. While China plans to use its massive fleet of coal power plants to balance out intermittent renewable generation, more energy storage is seen as the long-term answer as the country decarbonizes. Falling battery prices are helping to spur some investment. China nearly doubled grid-scale battery storage capacity in the first half of this year to about 14.3 gigawatts, according to data released by the China Electricity Council. There are still several problems. In many parts of China, power rates are the same at all times of the day, giving little economic incentive for storage systems to operate. (SD-Agencies) |
