AEP Ohio officials said on Tuesday that frequent blackouts in the Upper Arlington area have been caused by an extensive reliability improvement project.
The work is being done while the station is live and providing power.
AEP officials said that for employee safety, the station fault protection equipment has been made more sensitive.
They said that some of the nearly half-dozen outages customers have experienced in the past few weeks were the result of the increased equipment sensitivity, which they said has now been removed.
Upper Arlington City Schools said that both Upper Arlington High School and Barrington Elementary School have been without power a number of times in the past week.
AEP has now developed a mitigation plan to avoid future blackouts.
The project is expected to be completed by the end of the year.
