Abstract
This study aims to establish the potential impact on Great Britain’s future energy system, and total cost to consumers, of deploying tidal range generating assets in a range of scenarios. It follows the Strategic Outline Case (SOC) approach in HM Treasury’s Green Book Five-Case model. The focus of the Economic Case is an assessment of what impact there might be on GB consumers of each of the different scenarios, including no tidal range deployment at all. Different delivery models and subsidy mechanisms have also been considered to explore the potential delivery requirements of the studied scenarios.
The study compares three scenarios of varying total capacity, location and deployment timescales of tidal range generation assets around the UK coastline, as well as a counterfactual scenario where there is no tidal range energy generation. The NESO Future Energy Scenario 2024 Hydrogen Evolution pathway has been used as the basis of the electricity supply and demand profile to 2050, and the network upgrades planned in Holistic Network Design , and Beyond 20304 have been incorporated.
