05 - What difference does the fact that SHETL and SPT are regulated companies make?

As licensed regulated companies SHETL and SPT are obliged by law to develop and maintain an efficient, co-ordinated and economic system of electricity transmission and to facilitate competition in the supply and generation of electricity.  SHETL and SPT are also responsible for developing the transmission system and connecting new demand and generation to the grid network in accordance with the GB Security and Quality of Supply Standards.

All investment has to be approved by the regulators (Ofgem) and the Beauly-Denny upgrade proposal has been developed under license conditions.  The route chosen also complies with revised ‘Holford Rules’ which are the recognised industry approach to routing overhead lines amended to reflect Scottish circumstances.
