Project Objectives and Assessment Options for the market-wide half-hourly settlement Business Case

Guidance

We are using HM Treasury best practice guidance to develop the Business Case for the move to market-wide half-hourly settlement. This Business Case will use the Five Case Model methodology to examine the strategic rationale for change, the potential impacts of settlement reform and how to best manage and deliver reform. This includes an economic Impact Assessment, which will form the economic case of the Business Case.

This document outlines the work undertaken on the Business Case so far. This began with identification of the objectives for the project, and then continued with the identification of options to achieve those objectives. This document details the process of identifying the Project Objectives and long-list options, and explains the qualitative process undertaken so far to narrow down a short-list of options for assessment. This includes the options which we are currently considering on access to data for settlement.

These options will feed into the economic assessment in the Outline Business Case. The options will be developed iteratively as more is known about the design of the Target Operating Model and decisions are taken regarding key policy questions including access to half-hourly data for settlement purposes and whether or not to centralise functions currently performed by supplier agents.

If you have any questions on this document or views on the assessment of the options, please contact the Settlement Reform team at half-hourlysettlement@ofgem.gov.uk.
