Land-Based Wind

Taller Turbines are Unlocking Land-Based Wind for the Southeast

There is a common misconception that the Southeast lacks sufficient wind for large-scale wind projects. The truth is that it depends on the height of the developer’s turbines; the higher you go in the air, the more wind there is. The heights of turbines used in traditional development in western states such as Oklahoma were previously insufficient to reach the Southeast’s elevated resource, but this is no longer the case.


The advancement of wind turbine technology, specifically the emergence of “tall wind” turbines with tip heights of up to 700 feet, has been a game-changer for wind energy deployment in the Southeast. These turbines, now commercially available from original equipment manufacturers such as Vestas, enable the harnessing of wind resources in regions previously considered unsuitable, including vast areas of the Southeast.


This technological leap was predicted in 2014 when the Southeastern Wind Coalition (SEWC) and the National Renewable Energy Laboratory (NREL) collaborated to create custom maps exploring the potential of taller turbines:

SEWC and NREL's maps highlighting wind expansion potential for the Southeast by using taller turbines.

These maps have proven accurate, as tall wind technologies have been commercialized and are currently being constructed across the Southeast, most notably at AES’s Delta Wind project in Tunica County, Mississippi, which features 700-foot turbines, some of the tallest in the country.

As of Q2 2024, there are at least 20 active land-based wind projects in development in SEWC’s footprint, owing in large part to these turbine advancements:

The Delta Region is a Hotspot for New Southeast Wind Projects

As the Western United States approaches its capacity for optimal wind energy sites, attention is shifting to the Southeast, particularly to states in the Delta Region such as Arkansas, Mississippi, Louisiana, Tennessee, and Kentucky. This region is known for its vast agricultural fields and minimal developmental barriers, making it an attractive new frontier for onshore wind energy projects.

The Critical Role of Corporate Offtakers for New Wind Projects

The Southeast’s rising energy demand, driven primarily by the growth of data centers and electric vehicle manufacturing, highlights the critical role of corporate buyers in the region’s wind energy initiatives. Amazon, which is the off-taker for Amazon Wind US East in North Carolina (2017) and the Delta Wind project in Mississippi (2024), is significantly expanding its footprint with a $10 billion investment that includes the construction of two data centers in Mississippi. Projects like Delta Wind are critical for supplying clean electrons to the grid, which power these massive data centers and factories. The growing demand from corporations for more clean energy drives the development of such projects, establishing the Southeast as a prime location for wind energy development.

Online Land-Based Wind Projects in the Southeast

Sorted by Most Recent Projected Online Date

Delta Wind

  • Location: Tunica County, Mississippi

  • Capacity: 184.5 MW

  • Developer: AES

  • Highlights: Delta Wind Farm is Mississippi’s inaugural utility-scale wind project and the Southeast’s second major wind project, featuring some of North America’s tallest turbines. Vestas’ development arm, Steelhead, initially developed this historic project, which signaled the start of wind energy development in the Delta Region, and sold it to AES in 2022. Amazon is the offtaker of the project. Development began in 2017 and concluded in 2024.

  • Status: Online since 2024


Amazon Wind US East

  • Location: Pasquotank and Perquimans Counties, North Carolina

  • Developer: Avangrid

  • Online Since: 2017

  • Capacity: 208 MW

  • Highlights: The Southeast’s first large-scale wind project, Amazon Wind US East, demonstrates the potential for wind energy to support local farmers while advancing corporate sustainability goals.

  • Status: Online since 2017


Buffalo Mountain Wind Energy Center

  • Location: Anderson County, Tennessee

  • Capacity: 27 MW

  • Developer: Invenergy

  • Highlights: A pioneering utility-scale wind project in the Southwest. Initially established with three pilot turbines by TVA in 2000, Invenergy added additional turbines to the site in 2004. As its 20-year PPA with TVA concludes at the end of 2024, the project’s future is under consideration.

  • Status: Online since 2004
