Energy storage has the potential to provide a wide range of benefits to the electricity grid in Ireland. In this study TNEI have primarily focused on the ability of storage to mitigate dispatch down in a future scenario characterised by high volumes of renewable energy generation.
Ireland has seen rapid growth in energy storage with over 1 GW now connected to the electricity system. The battery storage projects have developed since 2020 with a focus on providing system services under EirGrid’s DS3 volume-capped and volume-uncapped procurement framework. To date, battery storage systems in Ireland have been designed primarily to provide fast-acting reserve services to help manage system frequency events. These batteries tend to have an average duration of discharge of around 1 hour but can provide large amounts of power in millisecond timeframes to contain frequency deviations on the power grid.
As the energy storage market has matured and new storage technologies and capabilities are now in development there is increasing focus on the ability of longer duration energy storage to provide congestion services which can help alleviate renewable constraints, facilitate operation of the system, displace fossil fuel generation and defer or reduce the need for new transmission infrastructure.
In this grid study TNEI have modelled the future transmission network in Ireland to explore the benefit of energy storage throughout the power system, in particular its ability to mitigate dispatch down of renewable generation.
Industry professionals working in the energy storage and renewable sectors as well as policy-makers, regulators and system operators.
