What are Technical Limits?
Technical Limits is the process being rolled out by Distribution Network Operators (DNOs) and National Grid Electricity System Operator (NGESO) (as part of the ENA’s 3-point plan), starting at the end of 2023, to allow distribution schemes to connect before large scale transmission reinforcement work has finished.
What are firm and non-firm connections?
The terms firm and non-firm are used in relation to grid connections in various ways. The two main ways are in relation to the connection design and network access, as we explain here.
What is a Cost Apportionment Factor?
A Cost Apportionment Factor (CAF) is part of the method by which electricity network reinforcement costs are passed on to connecting customers. A CAF is applied up to the level of the high-cost cap. Here we explain more.

What is Deep Connect and Manage?
Deep Connect and Manage (DC&M) was thought of as a way to allow additional distribution generation to connect to the electricity networks, without incurring huge transmission reinforcement costs. Here we explain more.
What is Connect and Manage?
Connect and Manage (C&M) was introduced to improve access to the transmission system for transmission-connected generators. Here we look at C&M, enabling works, wider works, higher system constraints and attributable liabilities.
What is a ‘Minimum Scheme’ for a grid connection?
The Minimum Scheme is the grid connection design that provides the required capacity at the lowest overall capital cost, as estimated by the Distribution Network Operator. It has its nuances though, as Pete Asont explains.
