Ashley Energy has acquired the historic Ashley heat and power plant located in downtown St. Louis from Trigen-St. Louis Energy Corporation, a subsidiary of Veolia North America.

Following the acquisition, Ashley has entered into a new 20-year agreement with the City of St. Louis’ Solid Waste Management and Development Corporation (“SWMDC”) to operate the St. Louis district energy system and supply reliable green energy to nearly 70 buildings, hotels, sports venues and businesses in the downtown business district.  The terms of the acquisition were not disclosed.
Ashley Energy Plant
Originally built in 1904 by the predecessor to Ameren Missouri Electric, the Ashley plant was originally configured as a coal-fired power plant. It was later converted to an oil-fired plant, and subsequently overhauled and developed as a natural gas-fired cogeneration facility that simultaneously generates both steam heat and electricity.

The electricity is sold into the wholesale power grid, and the steam is distributed to buildings through 17+ miles of piping that runs underneath the downtown St. Louis central business district.

“The St. Louis district energy system has reliably heated many of the city’s landmark buildings and businesses for over a century,” said Mason Miller, President of Ashley Energy.

“Hand in hand, in close partnership with the City of St. Louis, Ashley Energy will build upon the more than $20 million in energy infrastructure and modernized equipment invested in the Ashley plant over the past two decades to support the future growth and development of the City of St. Louis and deliver clean, reliable and cost-effective renewable energy to businesses across the city.”
