Ireland's power system is the first in the world capable of delivering 65pc of all electricity from variable sources including wind.

National grid operator EirGrid said it had achieved "record levels" of variable renewable energy following successful completion of a five-month trial.

It said the all-island power system was the first in the world to reach this level.

Grid operators face technical challenges in managing high levels of renewable power due to the possible impact on the system's stability.

High levels of wind generation are difficult to manage because of its inherent variability.

The grid was originally designed for conventional generation, such as coal, gas or oil generation, EirGrid said. Director of operations, planning & innovation, Robin McCormick, said it was a "significant milestone" and that higher levels were being sought.

"It is a clear demonstration of the excellent collaborative work across the entire energy industry on the island," McCormick said.

"We look forward to continuing progress towards 75pc variable renewable energy on the grid over the coming months and years."

The current record of wind energy on the system was set on March 14 last when 3,655MW of power was deployed.

The grid operator has recently named Mark Foley as its new CEO, following the departure of Fintan Slye to the UK system operator.

Mr Foley joined from Coillte, and previously worked at the Dublin Airport Authority.
