Quantifying the benefits of tidal stream energy to the wider UK energy system

Published 1 June 2022

Tidal stream is an emerging and exciting renewable energy source, with 30-40MW of new capacity set to be announced in 2022 through the UK CfD Allocation Round 4 (AR4). 

ORE Catapult commissioned a study to assess the potential benefit of tidal power to the energy system. This was funded through the TIGER project. Imperial College London (ICL) used their Integrated Whole Energy System (IWES) model to investigate how the introduction of tidal stream impacted the overall cost and composition of the energy system in 2050. This assumed a Net-Zero UK energy system, matching government targets. Tidal farm power output estimates were provided by the University of Plymouth, a partner in the TIGER project, and the University of Edinburgh.
