Clean energy generated in the western part of north China's Inner Mongolia Autonomous Region began on Friday its long-distance transmission to the country's southernmost island province of Hainan for the first time to ensure a stable power supply in Hainan during the National Day holiday season. On Friday, approximately seven million kilowatt-hours of clean energy -- including wind and solar power -- from western Inner Mongolia are expected to reach Hainan, 3,000 kilometers away, in batches during peak consumption hours through cross-region power transactions coordinated by China Southern Power Grid, State Grid, and Inner Mongolia Power Company. This cross-regional power delivery will continue until October 9, one day after the eight-day National Day and Mid-Autumn Festival holiday. It marks the first time that clean electricity from western Inner Mongolia has been transmitted to Hainan, further streamlining the large-scale power delivery mechanism across multiple operational zones.
