A hybrid renewable facility in Inner Mongolia aims to replace a coal-fired captive power plant at a Chinalco aluminum smelter. With 1 GW of wind, 200 MW of solar, and 135 MW/540 MWh of storage, the project could offset ~3,500 GWh of coal-generated electricity yearly. Success here could chart a path for decarbonizing energy-intensive industries reliant on captive coal. This addresses a critical hurdle for China's post-2030 emissions trajectory.
