Chapter 3

Provide value for money

We are proposing to spend £7.1bn over the five years of this plan in the baseline scenario. This is the sum of our operating costs and capital investment to deliver the range of priorities that stakeholders want.

Our plan embeds efficiencies from the T1 period and contains future efficiency commitments

We recognise that budgets are tight, and we have challenged ourselves hard during the current period to reduce our costs, ensuring we embed those into our T2 plan, as well as making further efficiency commitments for the future T2 period. 

To ensure we remain efficient over the T2 period, we have also committed to efficiencies in five areas. ​​These future efficiency commitments add up to a further £383m of savings. 

Our costs benchmark well for efficiency

Our network capital costs, the operating costs of running the business and our IT investments have been independently benchmarked by specialist organisations and we are in line with or better than current benchmarks. 

This chapter demonstrates our costs are efficient and that we will provide value for money for consumers in the T2 period.

Direct Opex Benchmarking (ITOMS)
A summary of our direct opex benchmarking, which is based on the International Transmission Operation Maintenance Study (ITOMS). The study covers inspections, maintenance and repair activities, and is also beginning to capture asset replacement activities and trialled overhead lines investments. The ITOMS program is a closed confidential forum where more than 31 companies representing 25% of electricity transmitted across the globe share information, practices, policies, processes and plans to compare efficiency, system performance and operational costs.
