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]
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]
| Part | County | Turbine Model | Number of Turbines | Unit Power | Total Power | Rotor Diameter | Hub Height |
|---|---|---|---|---|---|---|---|
| Part 1 | Carbon, Albany | Vestas V110/2000 | 28 | 2 MW | 56 MW | 110 m | 80-82 m |
| Part 2 | Vestas V136/4000-4200 | 47 | 4 MW | 202.1 MW | 136 m | ||
| Part 3 | Vestas V136/4000-4200 | 57 | 4 MW | 245.1 MW[7] | 136 m |
