The Irish Energy Storage Association (IESA) was established to promote the benefits of energy storage in Ireland. With the development of the DS3 programme, there is an increasing emphasis on energy storage in Ireland. Discussions between individuals and companies involved in the Irish energy storage sector resulted in the founding of IESA. 

The purpose of IESA is :

  • to represent parties in the energy storage space across a range of applications including; the provision of system services, exploitation of arbitrage opportunities in the energy sector, and maximisation of the benefits of renewable energy on the island of Ireland. This would involve a wide range of technologies including batteries, flywheels, super capacitors, hydroelectric, compressed air and thermal storage.

  • to follow DS3 developments and respond to Consultations representing the views of IESA members.

  • to actively promote energy storage on the island of Ireland in order to meet the needs of the I-SEM and assist in combating climate change. IESA aims to meet these needs through providing new system services to the Transmission System Operators.

IESA aims to influence policy decisions and implementation, follow DS3 developments, lobby on belhalf of parties in the energy storage space, represent the views of IESA members and promote energy storage on the island of Ireland.
IESA representing the energy sector on the island of Ireland

IESA represents the interests of the energy storage sector on the island of Ireland, by influencing policy decisions and implementation details through engagement with CRU, UR, SEM Committee, EirGrid, ESBN, Government Departments, EU and European energy bodies (for example in developing the Network Code).

IESA shares knowledge and experience with energy storage players worldwide, so that companies here can learn from significant energy storage developments around the globe. In addition, other countries can provide energy storage business and investment opportunities as well as learning from Ireland’s experience, particularly in relation to accommodating large scale intermittent generation on their systems.

IESA is signing International Affiliation Agreements with representative storage bodies from other countries.
