Leading the transition to a low-carbon future

To meet ESB's strategic objective of supporting the decarbonisation of the electricity sector, we are investing in renewable energy assets across a range of technologies including onshore and offshore wind and solar energy.

Our renewable energy Investments

At ESB, we believe in the power of wind energy and the potential it has in leading the transition to a low-carbon future. 

From our first 5MW wind farm in Crockahenny, Co Donegal in 1998 we have developed an onshore wind asset portfolio which has the capacity to supply almost 1GW of green energy to the homes, farms, hospitals, schools, and businesses throughout Ireland and the United Kingdom. Check out our asset map here for more information on all our wind farm sites across Ireland and the UK.

Mirroring the Government's 2030 target of 70% of all electricity used in the Republic of Ireland generated from renewable sources, ESB is committed to continue developing its own pipeline of low-carbon generation assets including wind farms. As outlined in our Brighter Future strategy, we plan to have more than 5GW of wind assets by 2030.

Current Onshore Wind Projects

  • In 2019, we announced our intention to partner with Coillte to create a joint venture to develop onshore wind assets on Coillte owned land in Ireland. More information here
  • In late 2019, ESB and Bord na Mona completed phase one of Oweninny Wind Farm in Co Mayo with 89MW. Planning has now been submitted for phase two of that project, adding 83MW to Ireland's renewable asset portfolio. For more information, click here. 
  • In 2020, Grousemount Wind Farm in Co Kerry, ESB’s largest onshore asset, came into commission which has the capacity to generate 114MW of green energy. For more information, click here.
  • We continue to develop a pipeline of around 1GW of onshore wind assets in Scotland and Wales.

Developing our offshore assets

ESB is committed to the development of an offshore wind portfolio in Ireland and the UK.

  • In 2019, we announced our partnership with Parkwind in the development of the Oriel and Clogherhead Wind farms. For more information, click here.
  • This builds on our acquisition of a stake in the Galloper windfarm in 2018 and the 50% shareholding in the Neart na Gaoithe 448 MW offshore wind farm project, located off the east coast of Scotland.
  • In October 2020, ESB joined with Edinburgh-based Red Rock Power Limited to form a 50:50 joint venture for Inch Cape Offshore Limited, a large wind farm development off the east coast of Scotland. Read more here


Solar energy is a key part of ESB’s Brighter Future strategy which seeks to shift electricity generation away from fossil fuels by developing renewable projects of scale, and in doing so, lead the transition to a low carbon energy future based on clean, reliable and affordable electricity.

Ireland is in a great position to take advantage of the significant reduction in the cost of solar energy that has occurred in the past few years as the technology has advanced. Ireland is expected to follow the trend of other European countries and see increasing deployment of rooftop and grid scale solar energy. Solar energy is suited to Ireland‘s climate and has the potential to provide a clean, diversified renewable electricity source for decades to come.

ESB has increased our investment in solar energy and developed a growing portfolio since 2015.

Our investment in Terra Solar Limited

In 2016 we acquired a minority shareholding in Irish solar development company Terra Solar Limited. In early 2020, all of the fully developed sites within Terra Solar Limited were transferred to ESB, bringing an additional 118MW capacity to ESB’s solar portfolio. Terra Solar Limited will be wound down in an orderly manner, as envisaged in the original business plan. This successful partnership has increased ESB's renewable portfolio in line with the company's Brighter Future strategy. 

Co-development agreement with Bord na Mona

In 2017 we announced a co-development agreement with Bord na Mona to develop solar energy projects in four locations in Roscommon, Offaly and Kildare. The joint venture, known as Sundew Solar, will access part of Bord na Móna’s land bank in strategic locations across the Midlands that are suitable for large scale solar energy projects. The joint venture brings together the expertise of two leading commercial semi-state companies in renewable energy with significant projects that support Ireland’s energy transition.

Our partnership with Harmony Solar

In May 2020, we entered into a partnership with Irish-owned renewable energy company, Harmony Solar, to develop ground-mounted solar projects in Ireland. Phase one will develop Harmony Solar’s existing 300MW portfolio primarily in Wexford and Kildare, with further phases on track to develop a total portfolio of over 1,000MW of large-scale solar projects. The development pipeline of the partnership will see an initial capital investment of €30 million, with further investment in the medium to long term as the pipeline comes to fruition.

ESB's Smart Energy Services solar projects

ESB's Smart Energy Services helps large customers to lower their carbon footprint, improving energy efficiency while deliver savings on their energy costs. To help the daa achieve a 33% reduction energy consumption at the airport by 2020, ESB installed 268 solar panels on top of the airport's reservoir system which will provide more than half of the reservoir's annual energy requirements. 

ESB recognises that hydrogen produced from renewable electricity will play a significant role in the decarbonisation of many sectors, including transport. To that end, we plan to use our existing capabilities and future renewable growth to become a leading player in large scale renewable hydrogen production, thereby enabling renewable electricity, in the form of electrons or green modules, to meet the energy requirements of Ireland’s future zero carbon economy.

Hydrogen and Transport Sector

The electrification of transport is critical to the transition to a low-carbon future, with ESB committed to enabling this as part of our Brighter Future strategy.

The transport sector is currently the second highest contributor to greenhouse gases in Ireland and the use of hydrogen, produced by electrolysers powered by renewable energy, to fuel heavy goods vehicles combined with battery EVs for cars and lighter commercial vehicles can enable zero emissions transport.

ESB has been actively engaging with Hydrogen Mobility Ireland (HMI), a partnership of businesses from across many sectors, together with public sector and academic stakeholders, with all-Island cooperation, to deliver a coordinated approach to the introduction of Hydrogen energy technology.

Battery storage is one of many energy and flexible technology solutions ESB is adopting to support Ireland’s climate target of 70 percent of electricity from renewable sources by 2030. 
ESB aims to develop a pipeline of projects to deliver  large scale batteries as well as additional flexible enabling technologies. This is crucial to supporting the grid and will facilitate ever more onshore wind, offshore wind and solar onto the electricity system in the coming decades. 

Battery Projects


In late 2020, we announced the development of our first major battery projects at existing ESB sites at Inchicore, Co Dublin and Aghada, Co Cork. 
Battery Energy Storage Systems will deliver 60MWh at Inchicore in Dublin and 38MWh at Aghada Generating Station in Cork supporting the national grid in providing storage capacity and stability for times of low wind.  
ESB is working with partners Fluence, Powercomm Group and Kirby Group in the delivery of these two projects, both of which should be complete by early 2022.  
In addition, ESB is developing further projects at Poolbeg and South Wall in Dublin into 2021 to enhance ESB’s presence in this segment of the market.   
Overall, the battery projects will support the grid system via the Distributed Services (DS3) market. ESB has sourced highly flexible and fast reacting battery technology, via Fluence, to ensure these batteries can provide a wide range of system services required by the national grid operator, Eirgrid.
