Northumberland County Council is set to build a solar energy farm in its own car park.
The council will install solar panels above parking spaces to provide energy for 40% of demand from county hall plus 60 electric vehicle charging points.
Half of the £2.3m costs will be paid by a European Regional Development Fund (ERDF) and the rest by the council.
The project is forecast to save around 240 tonnes of carbon per year and will be in operation within two years.
