Bramford to Twinstead Tee Connection Project


Since October 2009, we have been consulting on our proposals to build a new 400,000 volt electricity transmission connection between Bramford substation in Suffolk and Twinstead Tee, near Great Henny in Essex.

This is needed to connect a number of new power generators to the national electricity transmission network in East Anglia.

For more details please visit our Bramford to Twinstead Tee Connection consultation website.
