What's the project about

Low Voltage Active Network Management (LV ANM) project is evaluating the benefits of utilising ANM to manage constraints on LV networks, enabling further low carbon demand and generation to connect to the network while delaying or avoiding reinforcement. This project is demonstrating how interconnecting LV networks, which traditionally operated in a radial configuration, by using intelligent LV switches located at strategic points on our networks allows capacity to be shared across circuits and substations. The installation of intelligent LV circuit breakers in place of traditional fuses will ensure that the reliability of supply is not adversely impacted for our customers.

Objectives

Objectives and subsequent benefits of the LV ANM project include:

  • Develop a system which can be deployed quickly to manage network constraints
  • Facilitate greater numbers of low carbon technologies and generation connecting without the need for expensive network reinforcement
  • Place downward pressure on customers' electricity bills by deferring capital expenditure
  • Improve the quality and reliability of customers' supply
