National Grid says a planned power outage this weekend will affect around 7,300 residential and business customers in Western New York and the Finger Lakes.

The scheduled outage will happen from 7:30 a.m. to 4:30 p.m. on Saturday as crews replace two aging structures that support a transmission line. The utility provider says there was concern the structures may not withstand a major weather event.

The towns and villages of Avon, Caledonia, Lima and Livonia in Livingston County, Bloomfield and West Bloomfield in Ontario County, and Henrietta, Honeoye Falls, Mendon and Rush in Monroe County will be impacted by the outage.

“We understand the inconvenience of an outage of this length at this time of year,” said National Grid Regional Director Ken Kujawa. “The need to address these structures is urgent and came to light in recent weeks during work related to extensive electric system upgrades our crews are conducting in the area. The work requires [the] skills of many line and construction workers who are committed to the safe, reliable delivery of energy to our Genesee region customers. We’re grateful to our customers and local officials who provided feedback regarding the best date and time to safely complete this project, and we look forward to doing so on Jan 6.”

National Grid says individuals with special power needs, such as those with machines that deliver oxygen, or those who are more vulnerable to the colder temperatures, should prepare to be without electrical power on that day.
