This consultation letter seeks stakeholders’ views on our Project Assessment of a proposed reinforcement of the transmission system to the north west of Inverness, which was submitted by Scottish Hydro Electric Transmission plc (SHE Transmission). The proposed reinforcement is designed to facilitate the connection of additional generation, in particular renewables.

On the basis of the information provided by SHE Transmission, and the assessment undertaken by our consultants and ourselves, our initial view on the appropriate Strategic Wider Works1 (SWW) Output2 and Allowed Expenditure to be set for the Beauly Mossford reinforcement project are:

1. a SWW Output of an additional 252MW of transmission capacity at sub-boundary 10 to be completed in 2015; and
2. an increase to SHE Transmission’s RIIO-T1 Allowed Expenditure of £50.53 million for the efficient costs of delivering the project.

The remainder of this letter is structured as follows:

  • First, we provide some background on the proposed reinforcement and our previous regulatory decisions.
  • Second, we summarise our technical consultants’ assessment of the project.
  • Next, we outline our views on transferring a small amount of regulatory funding from the Beauly Denny reinforcement project (approved under the Transmission Investment for Renewable Generation mechanism) to the proposed Allowed Expenditure for the Beauly Mossford project (being considered under the SWW arrangements).
  • We then set out our initial assessment on the Project Assessment submission to date, including a proposed SWW Output and an adjustment to SHE Transmission’s RIIO-T1 Allowed Expenditure for the project.
  • Finally, we set out the next steps in the process including how to respond to this consultation.

We are seeking interested parties’ views by 13 February 2014. Stakeholders’ responses will help inform our assessment and decision on the project.
