Ireland climbs to 5th in latest EY renewable energy attractiveness index.
Ireland has been named the 5th most attractive country in the world to invest in renewable energy projects on a GDP-normalised basis.
According to the latest EY Renewable Energy Country Attractiveness Index ambitious energy transition plans, proactive policy settings and significant opportunities continue to attract investment in the rapidly expanding renewable sector.
“While some of this can be attributed to imported energy via interconnectors, it’s clear that the energising of new renewable energy projects on an almost monthly basis is playing a crucial role”
During 2023, an additional 0.6GW of new grid-scale renewable energy was installed across Ireland (0.2 GW wind and 0.4 GW solar) which represents a tripling of the 0.2 GW that was connected in 2022.
Ireland follows behind Denmark, Greece, Chile, and Australia in the normalised ranking of economies. In the overall index, the top spots are retained by the world’s largest economies, the United States, China and Germany, with the scale of the economies, the energy demands and the projects themselves attracting record investment.
Network gridlock
Globally, there has been a record level of investment, with a surge of US$1.8trn in clean energy investment in 2023, including US$660 billion earmarked for renewables.
In spite of this unprecedented investment, however, it is still significantly below what is needed to meet the COP28 target of tripling renewable capacity by 2030. Network gridlock and high capital costs are cited as consistent challenges globally at a time when rapid acceleration of investment and capacity is needed.
Ireland has also continued to expand its Corporate Power Purchase Agreements (CPPA) market, climbing one place to rank 16th in the CPPA Index, reflecting a growing use of these agreements in Ireland as organisations continue to invest in renewable energy to meet both their energy needs and ambitious individual climate commitments.
“It’s really positive that Ireland has placed so highly when it comes to our attractiveness in terms of seeking and securing renewable energy investment, but there is still much to do to ensure we are on track to meet 2030 goals,” said Sean Casey, EY UK and Ireland Energy & Infrastructure Consulting leader.
“Over recent years there has been a clear step change in the policy settings that enable investment in clean energy at scale. We are now increasingly seeing the return on this, with a year-on-year tripling of renewable energy added to the grid in 2023. Just recently the Environmental Protection Agency reported that power generation emissions were down 21% – while some of this can be attributed to imported energy via interconnectors, it’s clear that the energising of new renewable energy projects on an almost monthly basis is playing a crucial role.
“It’s also been really positive to see an increase in Corporate Power Purchase Agreements – where businesses commit to purchase electricity directly from renewable source. This is a market that is rapidly growing as organisations seek to secure renewable energy sources to meet their own climate commitments.
“These positive results for Ireland are set against a backdrop where on the surface, the global renewables sector is on a high. But despite last year’s surge in clean energy investment globally, investment remains below what is needed to meet the COP28 target of tripling renewable capacity by 2030. Years of underinvestment globally in infrastructure means network gridlock and high capital costs could also delay progress just when acceleration is needed. As an example, a 2023 International Energy Agency report found that approximately 1,500GW of renewables capacity was languishing in ever-growing queues to connect to the grid. Whether it’s here in Ireland or anywhere else globally, we need to redouble our focus on finding solutions that will accelerate delivery and connectivity of renewable energy at scale.”
Battery energy storage
As renewables proliferate and electrification grows, battery energy storage systems (BESS), will play a key role in a dynamic energy system by smoothing supply and demand peaks and helping defer the cost of grid expansion and upgrades. The role of BESS is an area of particular focus in the latest edition of the Renewable Energy Index. A fourfold increase in global BESS deployment is forecast from 2023 to 2030, reaching 572 GW/1,848 GWh.
“Scaling up battery energy storage systems can help solve multiple problems holding up clean energy progress, including stabilising and strengthening network infrastructure and enabling more distributed energy resources to connect to the grid. In Ireland, battery energy storage systems are currently providing much needed grid system services and will be an increasingly important part of our grid as we look to 2030 and beyond.
“In this context, the recent introduction of the Electricity Storage Policy Framework is very welcome. This policy clarifies the key role of electricity storage in Ireland’s transition to an electricity-led system, supports Irelands 2030 climate targets, and is a stepping stone on Ireland’s path to net zero carbon emissions. With Ireland’s current peak demand just under 6GW, it’s promising that 1GW of BESS is already operating in our electricity system and some 4.45GW of battery storage capacity is projected to be installed by 2030.”
