Southern Power Purchases Oklahoma Wind Project

LCG, May 30, 2018--Southern Company subsidiary Southern Power yesterday announced the acquisition of its tenth wind project - the 100-MW Wildhorse Mountain Wind Facility, located in Oklahoma. Roaring Fork Wind, a co-development partnership between Renewable Energy Systems Americas Inc. (RES) and Vestas, developed the project.

Wildhorse Mountain Wind Facility is scheduled to commence commercial operations in the fourth quarter of 2019. The project is expected to consist of 29 Vestas wind turbines. RES will provide the balance of plant construction of the facility, and Vestas will provide long-term maintenance of the turbines through a 20-year service agreement.

All electric energy, capacity and other attributes generated by the Wildhorse Mountain Wind Facility will be sold under a 20-year power purchase agreement (PPA) to Arkansas Electric Cooperative Corporation (AECC). AECC plans to sell the renewable energy credits (RECs) associated with the electricity produced by Wildhorse Mountain.

Southern Power's President and CEO stated, "We are proud to announce our tenth wind project as we continue to build the future of energy. Wildhorse Mountain is a great project for Southern Power's growing footprint and a shining example of our collaborative partnership with RES. Our long-time partner Vestas was also a key player in delivering on this project. We look forward to its completion and operation."

Wildhorse Mountain is Southern Power's fourth wind project within the state of Oklahoma. With this addition, Southern Power's wind portfolio consists of more than 1,600 MW of wind generation.

Last week, Southern Power announced that it has entered into an agreement to sell a 33 percent minority interest in its solar portfolio to Global Atlantic Financial Group Limited for a purchase price of $1.175 billion. The portfolio of projects involved in this solar transaction is comprised of 26 operating solar facilities representing approximately 1,700 MW of capacity.
