Site description

JB Sims Power Generation Plant was a one-unit coal-fired power plant owned by Grand Haven Board of Light & Power. The plant was located near Grand River in Grand Haven, Michigan in Ottawa County with a total capacity of 80-MW. The plant opened in 1983 and was retired in February 2020. Coal ash is placed into the Ash Ponds located onsite, which is regulated under the CCR rule. The ponds are each approximately 175-190 feet long, 70-80 feet wide, and 4-6 feet deep. Units 1 and 2 inactive ash ponds no longer receive CCR.
