China has become the world's largest wind power producer, surpassing the United States. The national power grid now serves as the largest wind power integration network globally, with the fastest growth in both wind and solar energy. In just five and a half years, China has achieved what took the U.S. and Europe 15 years to accomplish in wind power development.
According to reports, the State Grid has been actively supporting the growth of wind and solar power, which has significantly accelerated the development of these renewable energy sources. By 2012, the installed wind power capacity in its operating regions reached 56.76 million kilowatts, while photovoltaic capacity stood at 3.33 million kilowatts.
Despite this progress, the performance of wind and solar companies in China declined in 2012. Exports of wind towers, photovoltaic cells, and modules faced "double opposition" from European and American markets, putting immense pressure on the new energy sector. To counter this, the State Grid made significant efforts in wind power integration, operational management, standardization, and technological innovation, ensuring timely grid connection and acceptance of wind power.
In addition, the State Grid focused on strengthening the power grid and improving resource allocation efficiency. In 2012, the Jinping-Suannan UHV DC project, the world’s largest transmission system by capacity and distance, was completed. The Kaolin DC back-to-back expansion project, with the largest conversion capacity, also started operation. During the peak summer season, the grid utilized trans-regional and inter-provincial channels, along with large-scale UHV networks, to absorb surplus hydropower from the Yangtze and Yellow River basins.
Sichuan saw its highest electricity transmission ever, exceeding 11.1 million kilowatts, delivering 34.4 billion kWh of hydropower for the year—a record high. Qinghai also delivered nearly 5 billion kWh of hydropower, ten times that of 2011. These projects played a crucial role in large-scale energy distribution, economic collaboration, and optimizing resource allocation.
In 2012, the State Grid's hydroelectric power on-grid generation reached 551.8 billion kWh, representing a 26.33% year-on-year increase.
Moreover, the State Grid actively promoted the construction of pumped-storage power stations. As of the end of 2012, it had completed 17 stations, with four more under construction. The total operational installed capacity reached 14.06 million kilowatts, and another 4.06 million kilowatts were under development. This further enhanced the grid's flexibility and stability, supporting the growing share of renewable energy in the national power mix.

A 2-in-1 spring and grids combo is a storage system that combines the benefits of both spring and grid storage solutions. This versatile system offers a flexible and efficient way to store and organize a variety of items, from small parts to larger components.
