RIIO-ED1 Business Plan 

Our regulator Ofgem has confirmed fast track for WPD’s Business Plan as part of the RIIO-ED1 regulatory price review for the period 2015 to 2023. The decision promises settlement of the overall plan a year ahead of schedule.

We thank all the stakeholders that have participated in the wide range of engagement that we have carried out. Their views have helped us to shape and refine our plans.

Our proposals for RIIO-ED1 build on our track record of providing excellent customer service and industry leading network performance. We will also provide additional services for vulnerable customers and look to a smarter future by providing network capacity at a lower cost through innovative ways of running the network.
