1MW Shetland NaS Battery: Final Report

Abstract:

This report presents the findings from the Scottish Hydro Electric Power Distribution (SHEPD) Low Carbon Networks Fund (LCNF) Tier 1 project "1MW Battery, Shetland". The project commenced in 2010 with the aim of installing a grid scale energy storage device on the SHEPD network in Shetland and integrating this with an active network management system. The success criteria for the project were to: "reduce the peak demand on Lerwick Power Station"; for the battery to "cycle efficiently to meet the needs and profiles of the islands' generation and demand"; and to increase the knowledge and understanding of "battery operation within a network environment". The project has generated significant learning in key areas including: procurement, design, construction, installation, commissioning and safety. Time has been taken to detail knowledge items, necessary for project replication, which may benefit future projects. This experience has fed into the Energy Storage Operators Forum - established by SHEPD during the project - and ensures knowledge transfer to UK Distribution Network Operators. With the Tier 1 objectives complete, the battery energy storage system will continue to be trialled and evaluated under the Northern Isles New Energy Solutions (NINES) project.
