Chint Power, a CHINT Group company, has introduced a 500 Ah+ string-type grid-forming AC-side energy storage solution, claiming it to be the first of its kind worldwide. The solution features a string architecture, dual-stage topology, low-voltage coupling, and grid-forming capability, achieving frequency and voltage response times of under 20 ms compared to a national standard of 30 ms. According to the company, the solution supports constant power output across 0-100% SOC and can withstand short-circuit currents up to 3 times the rated level. It also features adaptive damping and virtual inertia technology to enhance grid stability, while safety is strengthened by fault warning and rapid isolation mechanisms. Chint Power claims the products have obtained UL and IEC certifications.
Recently, Chint Power's sister company Astronergy’s high-efficiency solar cell and module smart factory in Zhejiang was named among the 2025 list of Excellence-Level Smart Factory projects (see China Solar PV News Snippets).
Douyin Group, a subsidiary of the Chinese internet giant ByteDance, has initiated procurement for a green data center microgrid integrating wind, solar, and storage in China. The company is seeking partners for the entire project cycle, including investment, construction, and operation. The project involves building a microgrid system that combines wind power, solar PV, and over 200 MWh of lithium battery storage to enable flexible interaction with the main grid, improve energy self-sufficiency, and ensure uninterrupted data center operations. Currently in public tender, the project is scheduled to begin construction in November and be completed and operational in December 2025.
POWERCHINA’s new energy platform, POWERCHINA Renewable Energy Group Co., Ltd., has officially filed for an IPO. Its prospectus shows revenues of RMB 8.382 billion ($1.17 billion), RMB 8.728 billion ($1.22 billion), and RMB 9.81 billion ($1.37 billion) for 2022–2024, with net profits attributable to shareholders of RMB 1.768 billion ($246.5 million), RMB 2.329 billion ($324.6 million), and RMB 2.589 billion ($360.9 million), respectively.
Through the IPO, the company plans to raise RMB 9 billion ($1.26 billion) to fund wind and solar power projects, including large-scale PV and wind bases, agrivoltaics, animal husbandry-PV and aquaculture-PV hybrids, PV-based desertification control, as well as supporting power plants in load-concentrated areas. The funds will also support industrial chain development and infrastructure projects in collaboration with local governments.
As of March 2025, the company’s controlled installed capacity was 21.25 GW, including 9.89 GW of wind and 11.36 GW of solar.
According to data recently released by the National Energy Administration (NEA), China issued 271 million green certificates in August 2025, including 73.27 million for solar and 64.94 million for wind. For the first 8 months of 2025, the NEA issued a total of 1.878 billion certificates, with 427.94 million certificates for solar and 718.97 million for wind.
On the trading side, 464.25 million certificates were traded from January through August, including 195.72 million solar and 233.43 million wind certificates. Last month, NEA reported total electricity market transactions reached 624.6 billion kWh as of July 2025, up 7.4% YoY (see China Solar PV News Snippets).
At a press conference held by the State Council Information Office on September 19, a vice minister of the Ministry of Ecology and Environment outlined China’s latest progress in tackling climate change. Key points are as follows:
In recent years, China has accelerated the establishment of its carbon peaking and neutrality policy framework, with wind and solar installations already achieving the 2030 target ahead of schedule.
The national carbon emissions trading market has become the world’s largest in coverage, expanding this year to include steel, cement, and aluminum smelting industries, with a cumulative trading volume of 714 million tons and a value of RMB 48.961 billion ($6.82 billion).
The ministry has also guided the release of over 100 product carbon footprint accounting standards and launched a greenhouse gas emissions factor database to help enterprises address international carbon barriers.
On the adaptation front, it issued the National Climate Change Adaptation Strategy 2035, initiated 39 pilot climate-resilient cities, and strengthened risk assessments in key regions such as the Qinghai-Tibet Plateau.
