China’s AI Dominance Rests on Harnessing Excess Energy - https://www.bloomberg.com/graphics/2026-china-ai-energy-futu... | https://archive.today/6dq8B - October 8th, 2026

- Official curtailment figures — effectively, the share of renewable energy that could have been generated but was never sent out into the world, because of insufficient grid capacity or demand — suggest about 9% of wind and solar energy was wasted in the first half of this year. That almost certainly underestimates the problem, given the scale of green production.

- China could have generated an extra 401 terawatt-hours of power in the first six months alone, according to the Centre for Research on Energy and Clean Air, a nonprofit supporting efforts to curb pollution — nearly as much as Spain and the Philippines’ combined annual generation. [My note: !!!]

China Keeps Beating Renewable Targets And Missing Nuclear Ones - https://cleantechnica.com/2026/07/25/china-renewable-targets... - July 25th, 2026

> China set a 2020 wind target of 210 GW and finished the year with about 282 GW. Its solar target was 110 GW, while delivery reached roughly 253 GW. The later commitment to reach at least 1,200 GW of combined wind and solar by 2030 was crossed in 2024, six years early. By the end of 2025, China had about 640 GW of wind and 1,202 GW of solar, for a combined 1,842 GW. Nuclear moved in the other direction: about 50 GW against a 58 GW target in 2020, and about 62 GW against a 70 GW target in 2025. The current goal of 110 GW by 2030 may still be achieved, but the previous record gives no reason to convert it directly into a forecast.

China: Renewables now top 60 percent of capacity - https://denkstrom.org/en/goodnews/china-renewables-500-gw-ca... - June 1st, 2026

> If China maintains expansion at the 430-gigawatt-per-year level, installed wind and solar capacity would reach roughly 2,700 gigawatts by 2027. That would be more than five times the entire wind and solar capacity in the EU. Whether this value is realistic depends mainly on two factors: expansion of high-voltage transmission lines connecting generation and consumption regions, and political will to actually decommission the coal power plant fleet.

Every year renewables consume another ~10% of fossil generation in China, and should push out almost all fossil generation in the next 5-10 years, at current deployment rates. China is relying on coal for peaking until their battery deployment rates catch up to negate the need for coal generators.

China Battery Storage Use Surges After Policy Shift, Ember Says - https://www.bloomberg.com/news/articles/2026-07-15/china-bat... | https://archive.today/QBXxV - July 15th, 2026

- "As the power system integrates more renewables, the true value of batteries to China’s energy transition is becoming undeniable," Yang said. China added a record amount of new battery storage facilities in 2025, ending the year with more than half of global capacity. Growth has continued this year, with installed lithium-ion battery storage reaching almost 150 gigawatts by the end of the first quarter, according to Ember. The country is targeting 300 gigawatts of battery storage capacity by 2030, up from 136 at the end of 2025, in addition to expanding its fleet of longer-duration pumped hydro storage to around 160 gigawatts from 66.

- The government ended co-location requirements last year and most new battery storage projects are now standalone systems that can earn revenue through a variety of ways, such as by purchasing electricity when prices are low and selling it when they rise.

- Still, China can do more to improve utilization as its systems still fall short of the internationally recognized benchmark of about 350 cycles a year, Yang said. If they had reached that level last year, they could have captured and stored an additional 23 billion kilowatt-hours of renewable electricity, enough to power Singapore for about five months.

How China Built a Big Lead in Global Race for Batteries That Last for Days - https://www.bloomberg.com/news/articles/2026-03-03/china-s-b... | https://archive.today/i7n3B - March 3rd, 2026 (Control -F "China Leads on Batteries That Can Store Power for Days" graphic)

- BNEF analysts attribute China’s lead in the sector largely to policy support. Beijing identified LDES as a crucial component of its net-zero roadmap in 2023. The following year, China’s energy regulator launched 56 pilot projects, which helped launch the current boom. The country has built a massive lead in other climate tech sectors as well, from solar panels to hydrogen.
