Since July, persistent high temperatures have driven Gansu's new energy generation and power transmission to new heights. According to statistics from State Grid Gansu Electric Power Company and Gansu Electric Power Trading Center, in July, Gansu's monthly new energy generation reached 10.457 billion kilowatt-hours, a year-on-year increase of 8.91%, accounting for 39% of the province's total power generation. The province's electricity transmission volume hit 10.29 billion kilowatt-hours. This marks the first time Gansu has achieved a single month where both new energy generation and power transmission exceeded 10 billion kilowatt-hours.

The continuous rise in new energy generation and provincial electricity load has placed higher demands on the refined scheduling capabilities of the power grid. In response to the operational characteristics of a high-proportion new energy grid, Gansu's power dispatch departments, leveraging an advanced new energy storage cluster control system, have innovatively applied a scheduling model of "storing green electricity at midday and filling gaps during peak evening demand." This approach maximizes the utilization of energy resources and improves the efficiency of new energy use. In July, the province's energy storage charging and discharging volume exceeded 900 million kilowatt-hours, boosting the new energy consumption rate by 4 percentage points and effectively addressing the mismatch between new energy generation and peak user electricity demand.

Liu Kequan, Director of the Dispatch Department at State Grid Gansu Electric Power Company's Power Dispatch Center, noted that the soaring electricity demand during the scorching heat led to a maximum provincial load of 24.67 million kilowatts in July, up 15% year-on-year. Combined with the volatility of new energy generation, this increased the pressure on grid supply security and the difficulty of dispatch. "We proactively forecasted the output trends of new energy, optimized the scheduling of thermal power units to free up sufficient space for new energy consumption, and simultaneously predicted changes in the province's electricity load. We refined the dynamic balance of power and electricity, coordinating various regulation resources such as energy storage, thermal power, and hydropower to precisely match the generation and demand curves. This effectively addressed the pressure from increased electricity demand due to the high temperatures and ensured the safe and stable operation of the grid and reliable power supply."

To ensure new energy power is not only fully generated but also efficiently utilized and shared across provinces, Gansu's power grid has fully leveraged its key role as an important channel for the "West-to-East Power Transmission" project. The Gansu-to-Shandong and Gansu-to-Hunan power transmission projects operated at full capacity, transforming Gansu's clean energy resource advantages into tangible power supply support. In July, of the 10 billion kilowatt-hours of electricity transmitted out of Gansu, 5 billion kilowatt-hours were delivered through the Gansu-to-Shandong project.
