Energy marketing

Great River Energy is a member-owner of ACES, a nationwide energy management company. ACES transacts several billion dollars annually on behalf of its clients, who operate in nearly every wholesale electric market region of the US and have a collective portfolio of approximately 47,000 megawatts of both load and resources.

Providing services “as agent,” ACES represents its clients in the marketplace, working to manage energy risk. Because ACES does not buy or sell energy on its own behalf, it avoids conflicts of interest and ensures consistent and complete alignment with the best interests of the organizations it serves.

Fly Ash marketing

Fly ash is a by-product of generating electricity from coal. It’s called fly ash because it could fly out of our power plant stacks. Instead, we collect it. Years ago fly ash ended up in landfills, but we were determined to find ways to use it that were good for our economy and environment. We succeeded. Fly ash is now improving the quality of our environment and contributing to the strength of our economy.

Fly ash from Coal Creek Station is sold by our marketing partner, Boral Resources. The sale of the fly ash saves Great River Energy more than $1 million in landfill costs each year and generates more than $1.5 million in revenue for our members. It also helps protect the environment by reducing the amount of carbon dioxide emitted in the air during concrete production.
