The Filer City power plant uses a variated mix of fuels but is listed as a primarily coal fired. It also uses petroleum coke, wood waste biomass and tire-derived fuels. The generated power is sold to Consumers Energy trough a 35 year PPA agreement. It also produces 50.000 pounds of process steam per hour that is sold to the adjacent paper mill owned by the packaging corporation of america.[2]

Conversion to Natural Gas

In 2017 published an article that Consumers Energy wanted to convert the power plant from coal to natural gas and expand the plant to double it's current capacity.[4]

In a 2018 article S&P Global wrote that the Michigan Public Service Commission issued an order allowing Consumers Energy to convert the plant to natural gas but it still needs regional and federal approvals before it can proceed.[5]

In its 2018 annual report, Consumers Energy stated that the Federal Energy Regulatory Commission did not agree for the plant to operate as a Public Utility Regulatory Policies Act (PURPA) facility after the conversion. As a result of this ruling, the conversion to natural gas was canceled and the plant will keep using coal until the current power purchase agreements ends in 2025.[6]

As of 2021, the power station was reported as one of the least efficient US coal plants without a firm retirement date.[7]

TES Filer City Station Repowering

In 2004, Houston-based Tondu Corporation planned a coal facility in the small port City of Manistee,[8] which was turned back by significant citizen opposition,[9] who argued the project would kill off the region's tourist economy.[10]

In 2007, Tondu Corporation announced it was investigating converting the 70 MW subcritical coal-fired Filer City Station to a 180 MW IGCC coal plant, a project it estimated would cost between $200 million and $300 million. Tondu said the proposed conversion would more than double the power output of the plant, while also cutting emission levels by 50 percent. At the time, the company had not filed any permit applications.[11][12]

In September 2010, the Sierra Club concluded that the project had been abandoned.[13]
