One of the largest supermarket chains in Switzerland wants to become carbon neutral by 2023 and has fitted solar PV on 19 of its stores.

Coop installed solar inverter technology from ABB on 20,000 square meters of rooftops as a way of improving efficiency and cutting energy consumption by 20 per cent.

David Guthörl, head of energy in the sustainability unit at Coop, said: “Over the last decade, we have already reduced the average amount of energy we use for cooling in our stores and have made our product ranges and transport systems more sustainable.

“We were looking to work with our energy partners and use photovoltaics to power more of our stores. This latest investment has taken us one step closer towards our 2023 goal by adopting efficient renewable technologies.”

Giampiero Frisio, head of ABB’s Smart Power business line, said: “Our intelligent solar inverters are ideal for this type of high intensity application. Our focus is on writing the future of energy with safe, smart and sustainable solutions and we are delighted that Coop is now reaping the reward of our pioneering technologies.”
