The balance of nature in the Chacabuco Valley in Patagonia had been destroyed by intensive livestock farming. The Tompkins Foundation bought the land and has rewilded the area by establishing the “Patagonia Park” nature reserve.
For many years, the electricity for the park’s facilities, such as the hostels, camp sites, museum and information centre, was supplied by polluting diesel generators. Now, 100% of the park’s energy requirements are met by renewable resources. In winter and spring, when the rivers are full of water from the Andes, electricity is supplied by two micro water turbines. In summer, the foundation uses a photovoltaic installation. The remoteness of the park meant it was extremely important that the facilities use high-quality components requiring minimum maintenance. That is why the park relies on the TS 48 V battery storage system, with a discharging power of 54 kW.
