China General Nuclear Power Group said its wind power subsidiary will attract 14 strategic investors, with total capital of 30.53 billion yuan ($4.78 billion) raised for the company's future expansion of solar and wind, according to a contract signed at China Beijing Equity Exchange on Friday.

This is the biggest equity financing project in the country's new energy and power sector. The company's increase of capital leads to a release of equity of 33 percent, it said.

As the biggest nuclear enterprise in China and the third-largest worldwide, CGN's attempt to increase strategic capital has been favored by the market, with investors including State Grid Corp of China, the largest power provider in the country, and China Southern Power Grid.

The company's attracting strategic investment is in accordance with the government's attempt to achieve carbon peak by 2030 and carbon neutrality by 2060, the company said.
