THE location of a 33,000 volt substation was changed after concerns were raised by MP Mr Stephen Mosley, a ward councillor and neighbours.
The application was made on land at the Dunkirk Trading Estate, Chester Gates by Unilever Europe IT.
The U-shaped substation building would be close to two transformer bays, according to a report.
The occupiers of a nearby residential property together with Saughall and Mollington ward councillor Brian Crowe raised concerns due to the ‘unacceptable’ harm and discomfort to their quality of life.
The occupiers themselves felt the installation could pose a health risk.
Mr Mosley asked if another part of the site could be used which would not affect the neighbours.
The plans were revised and no further comments were received.
Cllr Crowe withdrew a request for the application to be called in to the borough's planning committee.
The substation would not have an unacceptable detrimental effect on the character of the area as it would be built between two large industrial units on the trading estate, planners suggested.
It would now be more than 70m away from the neighbours who would be screened by a 4m-high mound and established trees and hedgerows.
The application was recommended for approval on that basis and the borough council agreed that permission could be granted.
