Brattle principals Dan Harris and Serena Hesmondhalgh recently had two reports published by the Ofgem, the GB energy regulator, in which they assessed the cost-benefit analysis on the P229 ‘zonal losses’ proposal carried out by London Economics and Ventyx (LE/Ventyx). The Brattle Group was asked by Ofgem to analyze and review the work carried out by LE/Ventyx on modifying the Balancing and Settlement Code by introducing a seasonal zonal losses scheme, and to see if any additional quantitative analysis might be required. In their reports, Mr. Harris and Dr. Hesmondhalgh found that the conclusions presented by LE/Ventyx were accurate and based on an appropriate methodology.
