Great River Energy has executed commercial agreements for a new, large-scale energy storage project tied to the Emmons-Logan Wind project in North Dakota.
The project is set to integrate a lithium-ion energy storage system, leveraging the existing interconnection to maximize efficiency, economic value and renewable energy utilization.
With a project size of 140 megawatts, this energy storage solution offers Great River Energy autonomy over dispatching, optimization and market interaction.
The project is expected to generate annual revenues through MISO ancillary services, wholesale cost arbitrage and capacity value. Despite potential challenges linked to capacity accreditation shifts, the economic analysis underscores the venture’s viability.
Great River Energy anticipates positive financial outcomes, such as revenue diversity, reduced congestion impacts at Emmons-Logan Wind, avoided hedge purchase costs, and positive net capacity pricing.
“This project demonstrates our commitment to advancing energy innovation while ensuring economic benefits for our members,” said Zac Ruzycki, director of resource planning at Great River Energy. “We’re confident in the project’s ability to enhance grid services associated with wind energy and provide additional value to our member-owners.”
The investment comes with some risks, including uncertainties in MISO accreditation rules. However, Great River Energy is actively mitigating these risks by exploring contractual safeguards and monitoring ongoing MISO accreditation requirements.
Discussions with MISO and other stakeholders are ongoing to solidify the project’s future. The Emmons-Logan project is slated to be operational between late 2026 and early 2027.
