France eLLO 9MW DSG Fresnel CSP plant with energy storage starts solar field commissioning

Reported from CSPPLAZA: Recently, the 9MWe linear Fresnel DSG thermal power station developed by SUNCIM, a subsidiary of French Industrial Group CNIM, has begun solar field commissioning and is expected to realize grid-connected power generation in the near future. The project is also the first solar thermal power station in France to be commercialized.

The 9MW project named eLLO is located in the LI area of Pyrenees, French , covering 36 hectares and collecting 23,800 collectors. The 95200 heliostats has a total aperture area of 153,000 square meters. In addition, there are 9 energy storage devices to meet the heat storage time of up to 4 hours. After the project is put into operation, it can supply power to more than 6,000 households. EDF, the French power company, has signed a power purchase agreement with SUNCIM for the project for 20 years.

The project completed financing and started construction on October 14, 2016, with 75% from European Bank and 25% from private equity. It has a total investment of 60 million euros (about 478 million yuan).

The biggest highlight of the project is that it did not use the most common molten salt working medium as the heat storage medium, but chose steam storage. As early as 2010, the company built a 500kW small Fresnel water quality demonstration project in La Seyne sur Mer, France, which is equipped with a steam generation system to test the actual operation results.
