We want to keep our Members up to-date with all things Energy Storage related. 

IESA welcomes the EirGrid and Soni Decision to introduce an additional gate for the procurement of DS3 System Services under the Volume Uncapped arrangements. The TSO’s had consulted on 3 options to mitigate the impact of COVID-19 delays on existing and prospective providers. They consulted on three options and have now decided on the option strongly favoured by IESA. An additional procurement Gate will be conducted in 2021. It will be launched in mid February with a contract execution date of 1 July 2021. 

The ability of some new energy storage providers to tender for DS3 System Services under the previously planned timelines were seriously delayed as a result of the COVID-19 related national lockdown last Spring. The introduction of the additional Gate will allow these energy storage providers to tender in July rather than having to wait until the next Gate in October.” See link DS3 System Services Fixed Contracts Recommendation (

IESA calls for National Green Hydrogen Strategy

The Irish Energy Storage Association (IESA) is calling for the development of a National Green Hydrogen Strategy, and urging the Irish government to initiate the process as a matter of priority by establishing a Task Force for this.

Industry Consultations

IESA contribution to EU report:

IESA has a representative on the European Network of Energy Storage Associations (ENESA). ENESA meets twice a year in conjunction with the European Association for the Storage of Energy (EASE) which is a European Commission body.

The European Commission has just published a study on the contribution of Energy Storage to the security of supply in Europe.

IESA has recently sent responses to the following consultations: 

  • “Smarter HV & MV Customer Connections - New Approaches to Distribution Planning & Security of Supply Standards”

  • Initial Consultation on NECP

  • Commission Study on Energy Storage

  • Essential Role of Energy Storage in Decarbonising Energy

  • Enduring Connection Policy Stage 2 (ECP-2) Proposed Decision

  • Double Charging of Energy Storage Import and Export Capacities

  • Essential Role of Energy Storage. Innovation for the Network of the Future

Just Transition Report 

The Irish Energy Storage Association (IESA) welcomes the publication of the ‘Just Transition Report’. The closure of Lough Ree and West Offaly power plants is driven by Climate Action as is the work of IESA. We particularly welcome two key recommendations...

Energy Storage around the globe

IESA calls for changes to capacity market to encourage cleaner technologies, such as energy storage, with low missions 

Governements draft on Energy Storage 

In Sept 2019 the Irish Energy Storage Association was asked to contribute to a special issue of ETN (Emerging Technology News) on the Global Scenario regarding Energy Storage & Renewable Energy, to coincide with World Energy Storage Day and REI 2019. In addition to Ireland, the other contributors were China, Africa, USA, Australia, Japan and India.

ETN is published by the India Energy Storage Alliance. It interacts with industry stakeholders both in India and around the world as a dedicated news provider to the renewable and Energy Storage sectors.

The Irish Energy Storage Association is calling for amendments to the ISEM Capacity Market auctions, similar to those introduced in France and GB. France recently launched its first ever Capacity Market auction with a low emissions requirement thereby facilitating the decarbonisation of electricity. Storage featured significantly in the auction with contracts of over 250MW awarded. The GB market has followed suit and has made changes to its market – changes that are designed to remove barriers for low emissions plant and make it easier for cleaner technologies such as batteries to compete in capacity auctions.


The ISEM Capacity Market needs to reflect Ireland’s challenging 2030 and 2050 emission reduction targets. In particular IESA is calling for emission limits to apply to all future capacity auctions, thereby incentivising the replacement of the highest carbon emitting plants with cleaner technologies. 

IESA welcomes the recognition in the Programme for Government of the critical role that energy will play in the decarbonisation of the Electricity sector. 

Specifically IESA welcomes the commitments to:

- Strengthen the policy framework to incentivise electricity storage and interconnection.

- Continue Eirgrid’s programme “Delivering a Secure, Sustainable Electricity System” (DS3).

 - Support the clustering of regional and sectoral centres of excellence in the development of low carbon technologies, and   

- Invest in research and development in “green” hydrogen (generated using excess renewable energy) as a fuel for power generation, manufacturing, energy storage and transport. 


IESA looks forward to working with the new Department of Energy and all energy players in implementing the storage elements of this Programme.

Review of ECP-2 Decision June 2020 

The CRU has published its decision paper on ECP-2.


The highlights are as follows:

  • Target 115 connection offers in total for each ECP-2 batch period:

    • 85 for generation, storage and other system services technology projects (MEC>500kW).

    • 15 for non-batch projects and 15 for community-led projects, that cannot be processed on a non-batch basis

  • Prioritised by largest renewable energy generation (first 25 offers), then by planning permission grant date.

  • No more than 10 primarily storage and other system service technology projects

  • ECP-2 framework to encompass one batch application window per year for three years:

    • ECP-2.1 applications in September 2020

    • ECP-2.2 applications in September 2021

    • ECP-2.3 applications in September 2022

  • Batch formation October – December, batch processing January - December of the following year

  • Further opportunities for projects which are not going ahead to hand back their connection offer

  • Whilst ECP-2 offers will initially be issued on a non-firm basis as per ECP-1, contracted projects will receive scheduled Firm Access Quantities.

Network charging for commercial storage units 

The CRU has published a Consultation Paper on Network Charging for Commercial Storage Units; see link below. The Consultation Paper proposes that an interim solution be implemented in Oct 2020 pending a more enduring solution.

For the past 18 months the Irish Energy Storage Association (IESA) has been arguing with both the CRU and in Brussels for a change in the wires' double-charging regime, whereby storage units were required to pay wires charges on both imports and exports. In contrast Demand sites, Generator sites and Autogenerator sites are required to pay only on imports or exports. The double-charging placed storage sites at a significant disadvantage relative to other sites.

The Consultation states "It is therefore the CRU’s proposal to apply D-TUoS and cease charging G-TUoS to commercial storage providers as an interim approach to network charges for storage". This proposed change will have the effect of reducing the wires charges by approx 60% on, for example, a 50 MW transmission-connected storage unit with a max charging rate of 15%. 

IESA welcomes this consultation document and the proposal that the new arrangements will apply from next October.

The three documents in the Consultation are listed below:
