The prolonged electricity blackout affecting two of the Aran Islands has given renewed impetus to making the islands carbon-neutral, according to a local renewable-energy project.
As ESB Networks continued its efforts to restore electricity supplies to Inis Oírr and Inis Meáin, the project's chairman, Dara Ó Maoildhia, said support for the renewable initiative is now imperative.
Power was restored to 372 customers on the two Aran islands at about 9pm on Monday night, according to ESB Networks.
Comharchumann Fuinnimh Oileáin Árann Teo/Aran Islands Energy Co-op is working with the Sustainable Energy Authority of Ireland to make all three Aran islands “carbon-neutral” by 2022.
“The need is more obvious than ever after this experience,” said Mr Ó Maoildhia of the energy co-op.
All three islands lost power after a sub-sea cable at the mouth of Gregory’s Sound was ruptured on Friday last, but Inis Mór regained supply several hours later that same day.
Hardship
Its two neighbouring islands faced significant hardship for the past four days, with generators run by local businesses providing limited back-up.
Inis Oírr teacher Cormac Coyne was able to charge his mobile phones over the weekend using his own solar panels. However, he said that he and many neighbours have lost quantities of frozen food.
“We would rely heavily on freezers here, due to possible ferry disruption in bad weather,” Mr Coyne said. “Some people had top-ups from mobile generators, but the reality is that after 48 hours your food has to be thrown out.”
Inis Oírr’s doctor had to store certain medications in a fridge owned by a local business. However, communications were not completely severed as the clinics on both Inis Mór and Inis Oírr have a back-up radio system.
Broadband has been affected on all three islands over the past four days.
Use of solar energy has become far more frequent since the energy co-op initiated its programme, which also involves retrofitting houses to become more fuel-efficient.
Retrofitted
Mr Ó Maoildhia said that 200 of the 500 houses on the three islands would be retrofitted by the end of this summer.
ESB Networks has apologised for the outage, which it says was caused by a “fault” on the 9km-long sub-sea cable between Inis Mór and Inis Meaín. The cause of the fault, about 2km from shore in about 10m of water, has not yet been identified, it said, but it is “likely that the cable was struck underwater”.
“This cable has been in operation, without fault for almost 20 years,”it added.
Gales over the weekend and difficulties in acquiring a transformer hampered efforts to restore supply after generating equipment was shipped out to Inis Oírr on Friday. A transformer was sent by boat to Inis Oírr on Monday.
ESB Networks said it could not compensate customers for the interruptions, and advised affected homeowners to contact insurers.
