A couple 3,400 feet from a County Wexford ridge complained about turbine noise for 12 years, and a Dublin judge silenced half the wind farm after the operators ignored the manufacturer’s offer to fix it

The house sits below the ridge, and from the back garden three of the six machines are directly in line.

The couple inside moved from room to room for years looking for one that was quiet.

They ended up in a small room at the back, and that room sits at the center of the judge’s assessment.

The judge went out of his way to say that dealing with the noise properly is critical to the future of renewables in the country, which is not a hostile position.

The nearest machine is about 3,400 feet away.

Three of them have not turned since the summer of 2025.

They are not switched off. They are switched off permanently, by order.

Why a court silences a turbine instead of writing a check

Nuisance cases almost never end with a machine stopped for good.

Courts lean toward damages, because shutting down a generating asset is drastic and because noise limits are hard to translate into a legal standard.

The lever here was not the decibels. It was the evidence, or the absence of it.

The operators conceded liability on the eleventh day of the trial, which moved the whole argument from whether a nuisance existed to what remedy was fair.

At that point they offered a package. Turbines off from 10 at night to 7 in the morning, off again from 7 to 11 on weekends and public holidays, a software change for shadow flicker, and damages for continuing to run the rest of the time.

What they never produced was evidence that any of it would abate the problem, and both sides’ acoustics experts agreed that on the evidence before the court only a full stop would.

What the noise actually was

An average decibel reading would not have caught this.

The character of it was the problem. Low frequency tonal content with amplitude modulation, the rhythmic rise and fall that a meter can average away and an ear cannot.

It also appeared both upwind and downwind of the machines, which is unusual and removes the wind direction excuse.

The judgment describes it as unrelenting, with no escape outdoors or indoors.

Measured against United Kingdom guidance the levels were substantially exceeded, and the plaintiffs’ acoustics expert called it one of the worst intrusion experiences he had recorded.

The defense experts did not dispute the severity. They called the site an outlier.

What twelve years of ignoring it cost

The machines began running in May of 2013 and the couple went to court in 2018 after five years of complaints changed nothing.

Damages were set at 10,000 euro a year for the husband and 15,000 for the wife across twelve years, producing 120,000 and 180,000, with a further 60,000 in aggravated damages for the failure to engage.

That is 360,000 euro in total, and it is the smaller number.

The costs order landed two weeks later. The operators were told to pay 950,000 euro within fourteen days against a bill estimated at 2.3 million.

The judge found the operators had refused to cooperate with the local council investigation and had withheld their own operating data.

He also found that the turbine manufacturer had offered in 2019 to help build a mitigation plan, and that the operators did nothing with it.

What the judgment does not decide

The ruling is narrower than the coverage of it.

The judge states in the judgment itself that the conclusion is limited to the circumstances of this case, which was a twelve year record of non engagement with a solvable problem.

He also weighed the balance openly. These three machines produce a tiny share of the country’s renewable output, and that is what tipped it against them.

A different farm, a different share, or an operator with a mitigation file would not land in the same place.

Nor is this the first Irish finding on the subject. A separate action against a two turbine site elsewhere in the same county produced a ruling that noise amounted to unreasonable interference, and that one, not this one, was the first of its kind in Ireland or the United Kingdom.

The pattern that does travel is documentary, the same way a bonding flaw at one factory became a problem only once somebody produced the records, and the legal reading of this case says the same thing.

What operators should take from a hillside in Wexford

The immediate exposure is not in courtrooms. It is in monitoring protocols and complaint response procedures.

Nothing in this ruling makes ordinary turbine noise unlawful. What it punishes is a decade of unanswered letters.

The developer who logs every complaint, commissions the survey and keeps the manufacturer’s correspondence builds the file that this defense did not have.

The judge went out of his way to say that dealing with the noise properly is critical to the future of renewables in the country, which is not a hostile position.

The operators lodged no appeal, and the twenty eight day window closed with the machines already stopped.

Anyone curious what happens to hardware that reaches the end of its working life can look at where the blade fragments go, but the lesson from this hillside is earlier than that and much cheaper.
