e Energies has added 128 MW of natural-gas capacity at the Weston Power Plant near Wausau, Wisconsin, USA. The Weston RICE facility is jointly owned by We Energies and fellow WEC Energy Group subsidiary Wisconsin Public Service, with each company owning 50% of the capacity. We Energies said the new facility is the first large-scale project in the state to feature reciprocating internal combustion engines, or RICE units. The Weston RICE project includes seven units. Construction of the project began in 2022.
The Weston Power Plant site is home to three fossil-fuelled electric generating units that make electricity for WPS customers. Weston 4, the newest unit, is a state-of-the-art, 595-megawatt electric generator that uses clean coal technologies — making it one of the cleanest power plants of its kind in the country. Weston 4 began operating on June 30, 2008. WPS owns 70% (416.5 MW) and Dairyland Power Cooperative of La Crosse, WI owns 30% (178.5 MW). Weston Unit 3 began operating in 1981, Unit 2 in 1960 and Unit 1 in 1954. Unit 1 was retired in 2015.
The International Society of Automation (ISA) Electric Power Division named Weston 4 as their "2012 Best Facility." The award recognizes the power plant for its innovative use of digital control systems and optimization software. The ISA Power Division began in 1957 and has a current global membership of 2,400 members.
