Inverter and energy storage manufacturer Hoymiles has supplied an integrated mobile energy storage solution for electric fracturing at a coalbed methane exploration well in Loudi, Hunan province. The system meets the mountainous well site’s high-power demand where the rural 10 kV grid has limited capacity.
The solution combines mobile energy-storage vehicles with charging and discharging cabins in a multi-power conversion system (PCS) parallel architecture to support loads of around 7.5 MW. A DC cabin-swapping design lets operators replace a depleted battery cabin with a fully charged unit within 10 minutes. According to Hoymiles, the system charges from the grid during idle periods and discharges during fracturing operations to cover short-term power gaps, reducing reliance on diesel generators in remote areas with constrained grid access.
PV wafer and module manufacturer Gokin Solar plans to upgrade its existing module workshop in Guangzhou after receiving approval from the Guangzhou Ecology and Environment Bureau. The RMB 120 million project will require no additional land and is designed to produce 27.826 million modules annually. Of these, 6.9565 million will be n-type back-contact (BC) single- and dual-glass modules, accounting for approximately 25% of total output. The remainder will be n-type TOPCon modules.
Gokin Solar’s Guangzhou base initially focused on TOPCon technology before introducing BC production in 2025. Its 3-millionth BC module rolled off the production line in May 2026. The company said this latest upgrade will expand BC module output alongside existing TOPCon production.
Last month, Gokin Solar joined the United Nations Global Compact (UNGC) (see China Solar PV News Snippets).
Contemporary Amperex Technology Co., Limited (CATL) has signed an agreement with Xiamen Puquan Private Equity Fund Management Partnership Enterprise, the Guiyang Big Data Science and Innovation City Industrial Development Investment Fund, and other partners to invest in a proposed fund with total subscribed capital of RMB 1.50 billion. CATL will contribute RMB 400 million for a 26.64% stake, while the Guiyang fund will invest RMB 395 million for 26.31%. Xiamen Puquan will serve as the general partner and fund manager.
The fund will have a 10-year term and invest primarily in new and future energy, the integration of AI and digital technologies with the energy and power sectors, artificial intelligence, and future industries. CATL said the investment aims to expand its presence in areas such as the convergence of new energy and AI, as well as digitalization and intelligent upgrades across the new energy industry.
In September, CATL signed strategic cooperation agreements with TJNE, HKC Corporation, and other partners to expand its upstream lithium-ion battery copper foil supply chain (see China Solar PV News Snippets).
China’s National Railway Administration (NRA) has issued its 15^th Five-Year Plan for railway technology innovation, setting out green and low-carbon technology priorities to help the sector reach peak total carbon emissions before 2030.
The plan calls for research into coordinated ‘source-grid-vehicle-storage’ systems and integrated wind-solar-hydrogen-storage energy management. It also proposes demonstration projects for emerging storage technologies, including liquid-air and ammonia-hydrogen energy storage. Other priorities include large-scale deployment of wind-solar-storage microgrids at railway construction sites, advances in ultra-low-energy construction, PV and ground-source heat-pump technologies, and near-zero-carbon green construction demonstration projects.
For rolling stock, the plan supports demonstration operations of locomotives and rail vehicles using multiple energy sources, including batteries and hydrogen. It also targets advances in fuel-cell hybrid technologies and high-power hydrogen-powered mainline freight locomotives.
Shanghai has released its 2026-2030 plan for energy conservation, carbon reduction and the circular economy, targeting more than 5 GW of new PV capacity during the 15^th Five-Year Plan period. The city aims to reach 3 GW of new energy storage capacity by 2030 and increase the share of non-fossil energy in total energy consumption to 21.5%.
The plan calls for offshore PV clusters co-located with wind power and wider ‘PV+’ applications, including building-integrated PV (BIPV) and PEDF (photovoltaics, energy storage, direct current, and flexibility) systems in buildings. Shanghai will also develop diversified energy storage applications, green power direct connections, and smart microgrids, while promoting the large-scale integration of storage and distributed energy resources into virtual power plants. The plan also supports recycling retired power batteries and decommissioned wind and PV equipment.
