What is the Grid?

Across the UK, electricity is transported from where it is generated to people’s homes and businesses. This happens over two types of network – transmission and distribution.

Transmission is the large and long distance movement of electricity at high voltages. Transporting power at such high voltages is more efficient than at lower voltages, as it means less power is lost along the way.

The transmission system carries power from electricity generating stations (such as wind farms) to local distribution companies (such as ScottishPower Distribution), who then provide electricity to the vast majority of homes and businesses via lower voltage distribution networks.


Why is the Grid Important?

It is a critical means of ensuring electricity generated from renewable and other sources can be transported to where it is needed.

What is SR doing?

For Scotland's renewables industry to continue to grow, it is essential that several barriers are removed so that renewables can be integrated into the grid.

This represents a considerable challenge, and is of critical importance to our electricity-generating members. We are therefore currently working on:

  • Transmission Use of System Charging (TNUoS) – to ensure an equitable approach to charging users of the grid (such as an electricity generating plant)
  • An efficient and effective connection process for the distribution network
  • Timely delivery of grid infrastructure, for example pylons and cables
  • Swift and cost effective connections to the Scottish islands to harness the abundant wind and marine resources located there.

We work closely with our members to ensure that their viewpoint is clearly represented, especially in our engagement with National Grid, Ofgem and the Department of Energy and Climate Change.

SR recent achievements in this sector

  • SR Distributed Generation sub-group making very good progress on engagement with Distribution Network Operators (DNO) and RIIO ED1 price control, and on CMP192 (modification of the Connection and Use of System Code (CUSC) which alters user commitment liabilities and securities for generators)
  • SR Distributed Generation sub-group making very good progress on DNO and RIIO ED1 engagement and CMP192
  • Ongoing engagement on European Network Code development to ensure we are aware of issues and feeding into the process
  • SR is a partner in the ‘European North Sea Energy Alliance’ (ENSEA) project on energy system integration to coordinate and exploit research to increase competitiveness of the North Sea region.
