央视新闻丨充分利用光照时差，我国通过市场化交易实现跨省错峰绿电交易

Core Viewpoint - The article discusses the successful implementation of cross-province peak-shifting green electricity trading in China, particularly between Xinjiang and Beijing, highlighting the innovative use of time differences in solar energy generation and electricity consumption to optimize energy distribution [3][30]. Group 1: Cross-Province Green Electricity Trading - Since April, there have been four transactions of peak-shifting green electricity from Xinjiang to Beijing, with a total traded electricity volume exceeding 22.3 million kilowatt-hours [3][27]. - The trading mechanism leverages two key time differences: the solar illumination time difference of at least 2 hours between Xinjiang and Beijing, and the peak electricity consumption time difference, where Beijing's demand peaks in the evening while Xinjiang's solar generation peaks in the afternoon [7][12]. Group 2: Participation of Beijing Enterprises - Beijing Art Center has been utilizing the peak-shifting green electricity, consuming around 4,000 kilowatt-hours during peak performance times, all sourced from Xinjiang's solar energy [17][19]. - The Art Center's average monthly electricity consumption ranges from 500,000 to 800,000 kilowatt-hours, with plans to achieve over 80% green electricity usage starting September 2024 [19][22]. Group 3: Matching Supply and Demand - The transaction involves precise matching of supply and demand between Xinjiang's power generation companies and Beijing's electricity consumers, facilitated by multiple trading and scheduling institutions [23][25]. - The trading process is designed to optimize the timing of electricity delivery, ensuring that peak demand in Beijing aligns with the peak generation capacity in Xinjiang [29][30]. Group 4: National Green Electricity Trading Landscape - As of April 2025, the national cross-province green electricity trading scale reached 50 billion kilowatt-hours, promoting the optimization of renewable energy across the country [32]. - The expected green electricity supply to Beijing is projected to reach 35 billion kilowatt-hours in 2024 and exceed 40 billion kilowatt-hours in 2025, reflecting a growing trend in green energy utilization [30][32].
