Proposals for Britain’s biggest renewable energy project would hamper the creation of a £400m deepwater port at Avonmouth, the Bristol Port Company has warned. Financial Times

Entrepreneurs Terence Mordaunt and David Ord want to create the port to reduce costs for importers and carbon emissions from trucks.

However, the energy white paper yesterday revealed that plans for a £14bn 10-mile electricity-generating barrage that would span the Severn estuary downstream of Bristol are being evaluated by the government’s advisory Sustainable Development Commission.

The barrage could bar access to the port by biggest container ships.
