National Grid UK Showcases Benefits of Transmission Topology Optimization in its Annual Innovation Report

July 31, 2017 – Today, National Grid Electricity Transmission Ltd. released the 2016/2017 Network Innovation Allowance Annual Summary report, which showcases the potential of transmission topology optimization. National Grid found that the limits of major transmission constraints evaluated could be increased by up to 12.3 percent through the use of topology optimization. The corresponding annual cost savings are estimated to range £14-40 million.

National Grid owns the electricity transmission system in England and Wales and is the Great Britain System Operator. The topology optimization work was undertaken by NewGrid CEO Pablo Ruiz with economic consulting firm The Brattle Group. The Brattle Group was a member of the U.S. DOE ARPA-E project team that developed the first practical transmission topology optimization algorithms and is a licensee of NewGrid software.

National Grid states that “as the generation mix changes, finding new ways to optimise the network is increasingly important, both to increase system capacity and to reduce costs to consumers.”
