en.Wedoany.com Reported - A seminar on the system solution for Qinghai's green electricity transmission was recently held in Xining. Centered on the "dual carbon" goals and the construction of a new power system, the meeting focused on the challenge of long-distance stable transmission of high-proportion new energy from Qinghai's wind and solar base construction. It explored the use of new long-duration energy storage technologies to facilitate the implementation of a 100% green electricity transmission project and released the "Engineering Concept for Building Qinghai's Desert, Gobi, and Barren Land 100% Green Electricity Transmission Base System Solution Based on 'New Energy + Long-Duration Energy Storage'."
Wan Mingzhong, Chief Expert of China Energy Engineering Group, along with senior experts from State Grid Corporation of China, China Southern Power Grid, Electric Power Planning & Engineering Institute, and PetroChina Qinghai Oilfield, attended the meeting. Representatives from China Energy Engineering Group and its subsidiaries, including Digital Technology Group, Northwest Electric Power Design Institute, Losda, and Engineering Research Institute, also participated.
At the meeting, Wan Mingzhong stated that in the construction of the new energy system under the "15th Five-Year Plan," top-level planning has been made for large-scale new energy bases in desert, gobi, and barren lands and ultra-high voltage (UHV) transmission layouts, making a higher proportion of green electricity transmission an inevitable trend. Qinghai boasts abundant wind, solar, and hydropower resources, with clean energy likened to an inexhaustible "green oil," bearing the mission of building a "national clean energy industry highland." China Energy Engineering Group will continue to iterate the "new energy + long-duration energy storage" synergy pathway, improve the full-chain supporting solutions, and strive to explore a replicable and implementable new model for stable 100% green electricity transmission, helping Qinghai efficiently convert and scale up the transmission and consumption of its clean energy resources.
Experts at the meeting unanimously agreed that the "new energy + long-duration energy storage" model is highly aligned with the resource characteristics of Qinghai's desert, gobi, and barren lands and is a key pathway for achieving reliable regional green electricity transmission. Against the backdrop of the gradual phase-out of coal power, using compressed air long-duration energy storage as a foundation, combined with diverse energy storage technologies to build a flexible regulation power system that balances long and short durations and fast and slow responses, is of great significance for the construction of a national all-green electricity transmission base. Experts recommended accelerating the demonstration of the plan to ensure its inclusion in planning and implementation as soon as possible. The meeting also conducted thorough discussions on aspects such as grid planning integration, energy storage installed capacity ratios, UHV transmission line supporting facilities, project implementation timelines, and multi-party coordination mechanisms.
In the afternoon, the expert team conducted a field survey in Golmud, investigating the status of UHV transmission lines under construction and planned in the Haixi region, as well as the site selection for compressed air energy storage. After the survey, preliminary assessments of factors such as the region's wind and solar resource reserves, topography and geology, transmission corridors, and station access conditions indicated that a rational layout of compressed air energy storage power stations could effectively alleviate the power section bottlenecks in Qinghai caused by the concentrated grid connection of new energy and limited transmission channels. Experts recommended deepening the preliminary work on energy storage stations, promoting the synchronous planning and construction of energy storage projects with UHV projects, leveraging long-duration energy storage to smooth out fluctuations in new energy output, and fully unleashing Qinghai's clean energy transmission potential.
