Northwest China’s power grid has set a new record for daily renewable energy generation, reaching 1.58 billion kilowatt-hours (kWh) on March 26. This surpasses the previous record of 1.534 billion kWh set on March 15. On the same day, renewable energy accounted for 43.68% of the grid’s total electricity supply, with wind power output peaking at 56.91 million kilowatts (kW)—both historic highs.
To manage the surge in renewable energy, the State Grid Northwest Branch leveraged advanced forecasting models, achieving a 98% accuracy rate in predicting renewable power output. The grid operator also conducted early supply-demand assessments, adjusted coal-fired power plant operations, and coordinated with provincial power companies to brief local governments on the renewable energy integration outlook.
On March 26, a "real-time fine-tuning" approach was implemented, combining minute-by-minute adjustments with hourly optimizations. Transmission capacity was maximized, and power generation output was reviewed unit by unit to ensure efficient renewable energy utilization. Meanwhile, 341 electricity transactions were executed, facilitating the integration of an additional 80.09 million kWh of renewable energy while ensuring grid stability.
Energy storage systems played a critical role in balancing supply and demand. The Northwest Branch ensured that all available storage capacity was fully utilized, contributing to an additional 53.43 million kWh of renewable power generation. Pumped-storage hydropower operations were also optimized to further enhance grid flexibility, supporting a more balanced and resilient energy system. Through these efforts, the Northwest China power grid continues to expand its renewable energy capacity while maintaining reliable and secure operations.
