TERRA decided to invest in 2023 in a sustainable photovoltaic system. It is an important contribution to the shift away from fossil fuels towards renewable energy supply. With a peak output of 268 kWp (260,000 kWh per year), this solar power plant produces twice as much electricity as TERRA itself needs. The excess electricity goes into the local electrical grid system.
