GROVE CITY — About 8,000 borough residents will have no power for part of the weekend.

Crews will be replacing a 69,000 KV air break switch in the borough’s electrical substation, and the power will have to be turned off for work to be completed.

Power service will be turned off shortly after 10 p.m. Saturday and will be restored Sunday morning. The outage is expected to last about 12 hours.

To prepare for the outage, the borough recommends that residents:

• Learn how to manually open your garage doors

• Notify any security companies that monitor homes

• Protect computers, televisions and other sensitive equipment by unplugging them

• Keep refrigerator and freezer doors securely closed

• Have access to a telephone that operates without being plugged into an electrical outlet.

Additionally, the borough recommends that business owners without a backup power supply rent one for use during the outage.
