Flexible Distributed Generation (FDG) connections

What is a Flexible Distributed Generation (FDG) connection?

There are parts of the UK Power Networks distribution network where due to constraints such as capacity, voltage or reverse power flow issues the cost of connection is very likely to be higher than expected. This is because it will include a significant element of reinforcement work in order to overcome these technical challenges.

The FDG connection offering aims to provide a point of connection within the existing network without the need for/or ahead of reinforcement. The customer must be willing to accept temporary reduction to their export to ensure the network is kept within operational limits and the constraint is not breached.
