Peat bogs are wetlands filled with decayed plant material.
The 15-hectare peat bog stores the equivalent of 32,000 tonnes of carbon dioxide – equal to the average annual emissions of 22,000 petrol cars.
National Grid Electricity Transmission invested £120,000 in the restoration of the peat bog.
Chris Plester, Sustainability Specialist at National Grid, said: “This project has provided a unique opportunity to capture carbon and integrate biodiversity enhancement at the same time.
“It’s been an incredible journey for the whole team to watch the peat bog come to life once again.”
