The whole of the UK can now benefit from clean energy produced by solar, thanks to a new solar farm connected to the national grid.
The connection will allow the 152,400 PV module solar farm to supply some 73GWh to the national transmission system annually. It is also set to be co-located with a 49.5MW and 99MWh battery energy storage system, which adds an extra dimension to the project's flexibility of operation and, hence, value to consumers.
Completion of this project is a major milestone for renewable energy in the UK and provides further evidence that co-located solar and battery storage projects connecting directly to the transmission network will play an important role in the delivery of the UK's net zero plans.
