He said, “It is very quiet on that front now. We have had three calls in the last three weeks and one of those was from someone asking only for information. We have had just one from somebody who said they were having a problem with their radio, and we will look into that.”

The turbines, 400 feet tall when the blades are at their highest point, were installed earlier in the summer to provide one-third of the factory’s electricity.

With rising energy costs, the hope is that the £4 million project will make the factory more energy-efficient and help to secure its future and the jobs of 1000 people.

When the turbines went up, Michelin admitted there were potential problems facing nearby residents.

These included TV interference, noise from the blades and an effect called shadow flicker caused by sunlight shining through the blades.

In the event, few complaints have been received, Mr Bennett said. “There were some calls about TV reception, but very few of those were to do with the turbines,” he said.

Michelin had promised to provide a set-top box for anyone whose reception was compromised, but Mr Bennett said this measure had hardly needed to be used.

There had also been a handful of calls about shadow flicker and information has been taken about the location of these events and the time of day they happened to allow them to be checked.

It is possible for the blades to be stopped if a serious problem emerges. The real test for shadow flicker is likely to come in the winter, when the sun is lower in the sky.

Mr Bennett said, “I think we have been pleased with the reaction from residents and from the public at large. We have run the information line and followed up any problems that people have had.”

He added that the turbines were continuing to operate as expected and the company was pleased with their performance so far.
