The principle of the 2-WAY SUBSTATION (2WAY SST) is to return unused energy to the supply network with the highest effi­ciency. The objective is to create a system with high feed-in temperature from solar energy.

For that purpose, 2WAY SST uses Compact Heat Exchangers, Variable Speed Pumps, Controlled Valves and Controlled System. At CEA-INES facilities in South-East France (Le Bourget du Lac), the assembling of the 2WAY SST is in progress.

Two out of three heat exchangers (H1 & H2) and pumps (P1 & P2) have been already installed in June. An extra loop emulating the sanitary loop of the building is being set up, with the pressure tests already being passed.
