The Irish Times tells us that Endesa, a Spanish company, intends to sell its Irish operations. They include two water-side sites, at Great Island in Co Wexford and Tarbert in Co Kerry, as well as a near miss in Rhode, Co Offaly, and a fourth in Co Mayo.

The Irish Times says that Endesa had intended to change Great Island and Tarbert from diesel to natural gas. The Tarbert project received planning permission in December 2010; the Irish Times report was probably inaccurate in suggesting that a submarine cable from Tarbert would supply the ESB generating station at Moneypoint which, being a generating station, would be able to generate its own.
The old Tarbert power station
However, I had heard that Tarbert might have received its natural gas from the proposed storage plant at Ballylongford, near Saleen Pier whence Trinity College turf was sent to Limerick. A pipe from Tarbert might have supplied Moneypoint. I don’t think construction has yet begun.
The old Tarbert power station was built on the site of the Tarbert battery, the largest of the six Shannon estuary batteries and the only one to mount seven guns.
