The challenge now lies in the physical execution: building the ports, training the specialized workforce, and completing the interconnectors. If these enabling infrastructures are delivered, Ireland is well on its way to becoming the green battery of Europe, turning its legendary wind into a permanent national asset.

Frequently Asked Questions (FAQ)

Why has Ireland only built a small amount of offshore wind so far?

Ireland historically focused on onshore wind development. The offshore industry required a new legislative framework and a new regulatory body, both of which are now fully operational as of 2026, allowing for the current surge in project approvals and auctions.

What is the difference between fixed-bottom and floating wind?

Fixed-bottom turbines are anchored directly to the seabed and are suitable for shallow waters like the Irish Sea. Floating wind uses buoyant platforms moored to the sea floor, allowing for generation in much deeper, windier waters off the Atlantic coast.

Will these offshore wind farms increase the cost of electricity?

Recent auctions have secured prices that are competitive with wholesale electricity. In the long term, a high-renewable grid reduces Ireland’s dependence on expensive imported gas, leading to more stable and lower energy costs for the consumer.

How do the DMAPs help local coastal communities?

Designated Maritime Area Plans ensure that development is concentrated in specific zones, reducing the impact on the wider marine environment. Additionally, all projects must contribute to a Community Benefit Fund, which provides millions of euros annually to local projects.

Can Ireland really export its wind power to Europe?

Yes. Through the Celtic Interconnector to France and existing links to the UK, Ireland can sell excess power during high-wind periods. There are also plans for further interconnectors and green hydrogen production to maximize the value of Ireland’s wind resource.
