Approximately 1,600 coop members lost power with most back online within two hours of the incident. Consistently high temperatures were to blame for the explosion. Due to this year’s intense summer heat, transmission and distribution systems have lacked cool-off periods needed to help keep equipment from overheating. The Tahlequah Daily Press has the full story.
