S998 - Integrated Transmission Planning and Regulation (ITPR) project: draft conclusions


“Integrated Transmission Planning and Regulation (ITPR) Project: Draft Conclusions” IET evidence to Ofgem


The ITPR project is a review of the arrangements for planning and delivering the onshore, offshore and cross-border electricity transmission networks in GB. It aims to ensure that transmission is developed in an efficient, coordinated and economic manner, with the right investments made to protect existing and future consumers.

In its response the Institution of Engineering and Technology (IET) has focussed on the system aspects, including consideration of how the proposals for transmission system planning might work alongside IET recommendations for a system architect role to enable whole system technical integration of the end to end electricity system

IET emphasised that although the recommended Independent System Operator (ISO) should improve coordination in the planning of offshore and onshore transmission, and interconnectors, there remains an increasing need for co-ordination of transmission with distribution network planning, and indeed whole electricity system planning, if the potential benefits of an integrated approach are be fully realised. Thus, whilst establishing an ISO is a complementary initiative to establishing a System Architect, it is neither a substitute nor a reason to defer action.

The IET has also commented on a number of more detailed issues raised in the consultation document.
