Please note that distribution network constraints may be caused by a number of issues such as thermal, fault level, voltage constraints. Other constraints can be caused by physical space limitations within SSEN licence areas or limitations imposed by the Transmission System Operator.

Please note that the Constrained term at distribution level in our Central Southern England Generation Availability Map is assessed based on the addition of at least 5MVA synchronous generator resulting in SSEN network constraints. If you intend to apply for generator capacities below 5MVA you may well consider the constrained areas as well as unconstrained areas.
