TB Flats I & II Wind Farm

TB Flats I & II Wind Farm is a 301.1-megawatt onshore wind farm located in Carbon County and Albany County, Wyoming, United States. 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.

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.

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.

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:
