East Anglia 400kV network construction (1960s)
The 400 kV transmission network in East Anglia was built in the 1960s to supply regional demand centered around Norwich and Ipswich. The network was designed for the electricity needs of that era, not for transporting large amounts of offshore wind.
The network served regional demand for decades.
The network now acts as a bottleneck for renewable energy, as it can't handle the volume of offshore wind and other clean power being generated in the region.
The Bramford to Twinstead project is a direct response to the 1960s network's limitations, reinforcing the corridor to handle modern energy flows.
