BEIJING—Factories in China’s southwest have shut down and a city imposed rolling blackouts after reservoirs to generate hydropower ran low in a worsening drought, adding to economic strains.
Companies in Sichuan province including makers of solar panels, cement, and urea closed or reduced production after they were ordered to ration power for up to five days, according to news reports Wednesday. That came after reservoir levels fell and power demand for air conditioning surged in scorching temperatures.
