Which method should be adopted to verify the price of electricity? - Photothermal power station

News: In retrospect, China's first state-level CSP project - Inner Mongolia Erdos 50 MW Trough Solar CSP project has been brewing since 2003, starting site selection in 2005, and preliminary project feasibility study in the second half of 2007. At the end of 2008, it was reported to the National Development and Reform Commission that it took seven long years of suffering and finally adopted a concession bidding method. On January 20, 2011, it ended up with Datang New Energy's ultra-low price of 0.9399 yuan/kWh. However, as of now, the project still has no signs of actual work.

In fact, the Ordos project was originally planned to adopt the approved tariff method, but due to the high declaration price (more than 2 yuan/kwh) of the project partner STDP Solar (a joint venture between the German Solar Millennium and Inner Mongolia Green Energy), it also coincided with The cost of photovoltaic power generation has rapidly declined. Due to various considerations, the National Energy Administration eventually gave up its approval.

In the end, the National Energy Administration decided to use the concession tendering method to verify the price of the Ordos project, but the shocking low price of 0.9399 yuan did not give a good start to the China's CSP industry. The successful bidder, Datang New Energy, was also criticized by the industry. The title of "Spoiler".

At present, under the background that the government's on-grid electricity price has not yet been introduced, many of China's solar thermal power plant projects are currently under preparation or construction. How can the project's electricity price issue be solved in the end? This has become a huge stone hung in the hearts of project developers.

On the issue of electricity price, when the unified on-grid tariff has not yet been issued, the government can usually launch a concession bid for the target project to verify the project price, or the project pre-developer can submit a specific project price application to the government authorities, which will be approved by the government. . So, which way is better?
