Grundy County MiningStore Case Study
At the end of 2019, MiningStore launched a 7 MW bitcoin mining facility in Iowa, powered by a mix of wasted wind power and traditional grid power from Grundy County Rural Electric Cooperative (REC).
This strategic investment has delivered economic, environmental, and community benefits — proving that Bitcoin mining can be both profitable and sustainable.
An Inside Look
Stronger Communities, Lower Energy Costs
The mining facility provided a flexible industrial load, allowing Grundy County REC to reduce per-unit costs and achieve a 19% decrease in member electricity costs. This strategy grew operating revenue to $9M with 50.37% margins, establishing a powerful model for strengthened local infrastructure and sustainable economic growth.
Iowa: Leading the Way in Wind Energy
As the US leader in wind power, Iowa consistently produces surplus energy. MiningStore leverages this excess power with high-load, flexible facilities to turn stranded resources into economic value. The partnership with Grundy County REC demonstrates how Bitcoin mining can serve as a controllable base load that benefits the entire community.
A Model for the Future
With Iowa producing more electricity than it consumes since 2008, MiningStore turns the state's energy surplus into economic value through flexible, high-load mining facilities. We are committed to locating and expanding more facilities in Iowa to leverage this sustainable resource for the future of mining.
