Eversource Conducting Aerial Survey in Merrimack This Week

The Eversource Transmission Group will be performing statewide surveys of its transmission system this week, weather permitting.

The aerial patrols will involve a helicopter and are scheduled to take place between Monday, Aug. 10, and Friday, Aug. 14, weather permitting, according to Merrimack Police.

Eversource conducts the patrols as part of its routine inspection program for the maintenance of its transmission system.

The helicopter used in the patrols have an infrared camera that can spot excessive heat on transmission line components. Identifying this allows the company to recognize components that may fail in the future and allows it to schedule a repair or replacement of those components, improving reliability, according to the Merrimack Police Department.

Police advised residents and those with horses or farm animals that may be sensitive to noise to be aware due to the helicopter noise.
