All At Sea

Arklow, Co Wicklow, had a ‘first’ for Ireland: the first offshore wind-farm installation in the country, and the first in the world to employ wind turbines rated over 3 MW. Phase 1 of the project, commissioned in June 2004, consists of seven GE 3.6-megawatt generators. The total output of 25.2MW seemed good at the time but the improvements in technology since it was constructed are considerable. A second phase, currently being planned, aims to achieve an export capacity of up to 800MW.

Going back in time a bit, we can see that Ireland has always been at the forefront of wind technology. Above is a still from an RTE news piece on 23 October 1987. This reports on the installation of two state-of-the-art (then) wind powered generators on Cape Clear Island, in West Cork.

. . . The new technology was funded largely by the Germans and came in at a cost of around £500,000. The two wind-powered generators stand fifty feet above the top of the island and provide 30 kW each from the turning of their 12.5-meter blades. The National Board for Science and Technology claims that this new technology is the first of its type in the world as it integrates wind generation with diesel generators and battery storage creating a complete power supply . . .

The masts and turbines are still in place today, although they have been disused since the island was connected to the mainland for electricity supply via a subsea cable in 1996. (Below) we photographed the surviving turbines on the island in 2016.

Wind power goes back a very long way, of course. Here (above) are some very picturesque ancient examples from La Mancha, in Spain. Here’s another (below) – Pitstone Windmill in England: an interesting composition with newer technologies in the background.

In West Cork we are no strangers to the more recent developments in this expanding field, although at present all land based. The scale and form of the machinery is, of course, increasing apace. These examples are on the hills close by us:

But it’s the vast resource of our relatively benign coastal waters that offers the most for the country’s still young wind-power industry. There’s a further example being planned in County Wicklow: the Codling Bank Wind Park scheme. Currently in the consultation stages, it is hoped that construction will be completed in late 2028. 73 turbines are planned, to be sited on the shallow Codling Bank, some 20km out in the Irish Sea. This project – the largest so far in this country – has the potential to power 1.2 million homes using natural resources. It will also provide welcome employment for a large work force. And – in my eyes – an elegant contribution to the marine environment. Well done, Ireland!
