Southern Power, a leading U.S. wholesale energy provider and subsidiary of Southern Company, today announced the acquisition of its tenth wind project – the 100-megawatt (MW) Wildhorse Mountain Wind Facility, located in Pushmataha County, OK.

Roaring Fork Wind, a co-development partnership between Renewable Energy Systems Americas Inc. (RES) and Vestas, developed the project. Once operational, all electric energy, capacity and other attributes generated by the facility will be sold under a 20-year power purchase agreement to Arkansas Electric Cooperative Corporation (AECC).

“We are proud to announce our tenth wind project as we continue to build the future of energy,” said Southern Power President and CEO Mark Lantrip. “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.”

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.

Wildhorse Mountain is expected to achieve commercial operation in the fourth quarter of 2019. AECC intends to sell the renewable energy credits associated with the electricity produced by Wildhorse Mountain. AECC does not claim that the electricity to be sold from this resource to its member cooperatives and others is “green,” “renewable,” “clean” or has any other environmental attribute.

“AECC works on behalf of more than 500,000 electric cooperative members to add resources, like the 100 megawatts of capacity from Wildhorse Mountain Wind Facility, to its generation portfolio,” said Duane Highley, president and CEO of AECC. “This wind facility along with AECC’s diverse, reliable generation portfolio provides energy at the lowest possible cost to our members.”

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. Southern Power’s wind facilities are part of the company’s 3,000-MW renewable fleet, which consists of 39 solar, wind and biomass facilities operating or under construction.

This project aligns with Southern Power’s overall business strategy of strengthening its wholesale business by acquiring and developing generating assets that are covered by long-term contracts with counterparties with strong credit support.

Hog Creek – SMECO

Broomfield, CO – Renewable Energy Systems (RES), a leader in the development, construction, and operation of wind,
solar, transmission, and energy storage projects in the Americas, is pleased to announce that construction has begun on
the Hog Creek Wind Project located in Hardin County, OH. The project, owned by EDP Renewables (EDPR), is on
schedule to be operational before the end of 2017 and will provide enough clean electricity to power approximately
19,000 Ohio homes. RES completed the project development and transferred Hog Creek wind project ownership to
EDPR in 2017.

Hog Creek Wind Project will be a 66-MW project comprised of 30 Vestas V110 2.2-MW turbines. The National
Renewables Cooperative Organization (NRCO) facilitated the 20-year power purchase agreement with Southern
Maryland Electric Cooperative (SMECO). The project is expected to create 235 jobs during the peak of construction and
up to seven permanent jobs once operational.

“RES is grateful to the surrounding community for being supportive during the development cycle for this project. That
patience has paid off and now Hog Creek Wind Project will bring significant benefits to the region,” stated Shalini
Ramanathan, VP Origination, RES in the Americas. “RES is pleased to construct our third project for EDP Renewables, a
tremendous partner in bringing the benefits of renewable energy to communities across North America.”
“The Hog Creek Wind Project is a great addition to EDP Renewables’ growing wind portfolio in Ohio,” said Ryan Brown,
EDP Renewables North America Executive Vice President – Eastern Region and Canada. “Moreover, EDP Renewables is
eager to make additional investments in Ohio to provide more economic benefits to the state’s residents and its
communities. EDP Renewables applauds those who are working to ease Ohio’s onerous siting regulations, which, if
amended, would encourage more wind development in the state.”

“Once again, NRCO has assisted SMECO with procuring wind energy to help the cooperative meet state requirements. As
we add more and more renewable energy to our power portfolio, we demonstrate our commitment to environmental
stewardship,” said Jeff Shaw, SMECO Vice President of Distributed Energy and Sustainability.

With the completion of the Hog Creek Wind Project, EDPR will expand its operational capacity to more than 260 MW in
the state of Ohio. The project will have a significant impact on the region in providing a number of economic benefits to
its surrounding communities. Hog Creek Wind Project will make property tax payments to Hardin County estimated at
$594,000 per year and more than $10 million will be paid to local landowners through the life of the project. And in the
community, Hog Creek Wind Project recently donated $20,000 to the Hardin County Historical Museum to upgrade the
electrical system in the building. In addition, the project has established an internship program with Ohio State
University that is expected to begin in 2018.

Hog Creek Wind Project is the first wind project that RES has developed or constructed in Ohio. The company has
previously developed three innovative energy storage facilities across the state (Clinton, Willey, and Battery Storage of
Ohio). With the addition of the Hog Creek Wind Project, EDP Renewables will now own and operate a total of three
wind farms in Ohio. Others include the 100 MW Timber Road II Wind Farm (operational since 2011) and the 101 MW
Amazon Wind Farm US Central (operational since 2016).

About SMECO – The Cooperative Difference
Eighty years ago, when rural areas needed electricity, cooperatives were created. Visionary men and women helped to
form SMECO, which now provides electric service to more than 160,000 customers in Charles County, St. Mary’s County,
southern Prince George’s County, and most of Calvert County.
Co-ops are distinctly different from investor-owned utilities because co-ops are owned by their customers. Customermembers elect the men and women who serve on the Board of Directors. They share the responsibility of ownership by
financing the cooperative’s operations, but they also share its rewards.
Each year, SMECO’s margins—revenue less expenses—are allocated to customers’ capital credit accounts. SMECO uses
margins as working capital for new construction and system improvements. Then, when the Board determines that the
financial condition of the co-op warrants, members receive a refund.
As a cooperative, SMECO will always put its members first and be responsive, reliable, and resourceful—the power you
can count on.
