Lighting that struck a Troy utility substation Tuesday causing blackouts did not completely damage the structure, officials said.

Though Troy Mayor Jimmy Lunsford said city and power officials originally thought its stricken transformer would have to be replaced, it was determined Wednesday its parts are salvageable. As a result, the city could save hundreds of thousands on repairs.

“We will replace the parts that burned in the lightning strike,” Lunsford said.

The historic lightning damage caused power to blackout in the downtown region and north side of Troy for nearly three hours Tuesday. That includes three polling locations that lost power during the primary elections.

Lunsford said the city originally thought it might have to replace the entire transformer, which would have cost between half a million to a million dollars.

It’s still too early to tell just how costly the repairs will be, but Lunsford estimates a savings of hundreds of thousands of dollars.

He said the power company is working to order parts now, and he hopes the repairs will be complete in the next few days without any additional power outages.

“There is no need for a scheduled power outage at the city.

“We are able to handle the loads of the other two transformers while making repairs,” he said.
