TB Flats I & II Wind Farm is a 301.1-megawatt onshore wind farm located in Carbon County and Albany County, Wyoming, United States. ^[3] The project was developed by Invenergy and later transferred to PacifiCorp as part of their Energy Vision 2020 initiative. It comprises 132 turbines manufactured by Vestas, specifically the V110-2.0 MW and V136-4.3 MW models. ^{[2] [4]}

Substation and transmission

The Aeolus substation near Medicine Bow serves as a critical connection point for TB Flats I & II, linking the wind farm to the broader PacifiCorp transmission grid. PacifiCorp’s Gateway South transmission project facilitates the delivery of wind-generated power to neighboring states. ^{[1] [4]}

Economic and environmental impact

The construction and operation of TB Flats I & II created between 1,100 and 1,600 jobs during the development phase and is expected to generate approximately $120 million in tax revenue over its lifetime. The wind farm contributes to diversifying Wyoming’s economy while providing clean, renewable energy capable of powering more than 100,000 homes annually. ^{[5] [1]}

Development and construction

The development of TB Flats I & II began under Invenergy in 2019. Construction was completed in 2020, with the farm becoming operational in 2021. The wind farm consists of three sections: ^[2]
