Cost of containerized energy storage systems in Ireland

By contributing to security of supply, helping to support renewable capacity, and displacing fossil fuels in the balancing market, energy storage can deliver a net saving to end consumers in Ireland of up to €85m per year.

In Ireland, demand for home battery storage systems — even without solar panels — is growing rapidly as homeowners look to reduce costs and gain energy independence.

This is the first electricity storage policy published in Ireland. The Irish Government's Climate Action Plan 2021 set out the need for an energy storage policy for Ireland to support 75% reduction in power sector CO2 emissions by 2030.

Energy Storage Ireland is a newly established representative body composed of industry members who are active in the development of the energy storage market in Ireland.

Appropriate and timely regulatory and market design is therefore essential to allow the deployment of energy storage in Ireland at the scale required to achieve current environmental policy objectives. However, the current policy framework is unsuitable to deliver the volumes and types of energy storage we will require.

Today, an estimated 4.67 TWh of electricity storage exists. This number remains highly uncertain, however, given the lack of comprehensive statistics for renewable energy storage capacity in energy rather than power terms.
