Costa Rica Super Energy Storage Battery

Two 40-foot- MTU battery containers from Rolls-Royce with a total storage capacity of 4,275 kWh and an output of 1,500 kVA are used to meet peak electricity demand, increase the company’s own use of solar power, and relieve pressure on the public grid. 690 photovoltaic panels with 255kWp capacity have been installed by solar provider Swissol SA, Alajuela, Costa Rica, on covered parking spaces at Proquinal and connected to the battery containers to support the system.
