Perovskite manufacturer SunFlex New Energy has deployed two flexible perovskite solar applications in China, covering smart bus stops and shared bicycles. Its smart bus-stop system in Zhuji, Zhejiang province, is expected to generate about 1,000 kWh annually and reduce carbon emissions by approximately 0.68 tonnes per site each year. By avoiding long-distance cabling, the company says the system can save up to RMB 20,000 per installation in grid-connection and labor costs. The current design combines perovskite generation with conventional electricity, while SunFlex plans to launch a fully solar-powered version in 2027.
SunFlex has also partnered with bike-sharing operator Hello Ride to develop shared bicycles fitted with lightweight flexible perovskite films and smart positioning systems. The bicycles have been deployed for road testing at Suzhou’s Yangcheng Lake Peninsula. The company says the films can keep generating electricity in overcast, rainy conditions.
In July, SunFlex New Energy and its research partners published two studies in Nature addressing efficiency and stability challenges in perovskite solar cells (see China Solar PV News Snippets).
State Grid Corporation of China, the state-owned grid operator, has launched a green power direct supply simulation and economic assessment module on its New Energy Cloud platform. Currently in trial use, the tool has been piloted by State Grid units in Hebei, Jibei, Liaoning, Shandong, Ningxia, and Xinjiang, with further upgrades planned.
Users can enter parameters including wind and solar output, electricity demand, power prices, line parameters, and investment costs to simulate project operations and assess overall project returns, generation-side returns, and load-side returns. An optimization function compares different power-source and energy storage configurations, helping investors evaluate project economics and optimize source-load-storage arrangements.
Shudao Investment Group’s subsidiary plans to develop an integrated solar thermal-PV demonstration project in Sichuan province's Aba Tibetan and Qiang Autonomous Prefecture. The overall plan calls for 2 GW of capacity, comprising 1.8 GW of PV and 200 MW of solar thermal generation, with total investment estimated at approximately RMB 9.2 billion.
The local ecology and environment bureau has approved the environmental impact assessment (EIA) for the first phase, which will have 1 GW of capacity and an investment of around RMB 4.425 billion. It includes a 900 MW grassland-compatible PV plant and a 100 MW molten-salt tower-type concentrated solar power (CSP) plant. The project will also include energy storage facilities and a reserved connection for centralized clean heating, designed to serve approximately 500,000 m² of buildings in Aba County’s urban area.
Located at an elevation of 3,600-3,900 m, the facility will feature a 255 m solar tower, a heliostat field covering about 400,000 m², and molten-salt thermal storage for grid peak regulation.
China’s National Energy Administration (NEA) has issued implementation guidelines to promote the integration of coal-fired power and renewable energy across five scenarios: joint transmission and consumption of nearby renewables through public coal plants; clean heating coordinated with combined heat and power plants; offshore wind connected to coastal coal plants; bundled use of renewables with captive coal plants; and renewable energy replacing a coal plant’s own energy consumption.
The guidelines state that the straight-line distance between a renewable energy site and the associated coal plant should generally not exceed 100 km. For three scenarios involving nearby renewables and public or captive coal plants, as well as offshore wind connected to coastal coal plants, projects are encouraged to cut annual carbon emissions by at least 5% from pre-integration levels, with a target reduction of 10%.
Electricity curtailed from the renewable energy portion of eligible integration projects will be excluded from renewable energy utilization statistics and assessments. The policy also encourages deep peak-load regulation upgrades, energy storage and thermal storage, and transmission-capacity expansion. In addition, the government will provide central funding support to eligible projects and support their participation in electricity and carbon markets.
China’s Ministry of Industry and Information Technology (MIIT) has issued an implementation plan for dual controls on carbon emissions across the industrial and IT sectors. By 2030, the plan targets a reduction of more than 17% in CO₂ emissions per unit of value added and a decline of more than 10% in energy consumption per unit of value added at industrial enterprises above the designated size, compared with 2025 levels. This category covers what it calls large enterprises, i.e., those with an annual core business revenue of RMB 20 million or more.
The plan calls for a carbon-management framework covering local-government assessments, sector-level controls, corporate carbon management, project carbon evaluations and product carbon footprints. It also calls for stronger enforcement, diagnostic services, technology promotion and standards to improve carbon-emissions management in key industries.
MIIT plans to support the construction of about 500 national-level zero-carbon factories and zero-carbon computing facilities by 2030, while promoting electricity substitution and green-energy use. Industrial companies and parks will be encouraged to develop green microgrids integrating PV, wind power, high-efficiency heat pumps, new energy storage, hydrogen, waste-heat and pressure recovery, combustible waste, and smart energy-management systems.
MIIT recently proposed higher efficiency requirements for TOPCon, HJT, and BC solar cells and modules (see China Proposes Tighter Solar PV Manufacturing Standards).
