Spirae is a company based in Fort Collins, Colorado that provides smart grid control solutions for distributed energy resources. Their Bluefin software platform allows utilities to intelligently control assets like wind turbines, solar panels, and energy storage to manage the distribution grid. Spirae has implemented projects in Denmark, Colorado, and the Pacific Northwest to test their control capabilities like facilitating islanding and providing ancillary grid services. They also operate a test lab with Colorado State University to validate systems with high renewable distributed generation.
