The Koda Energy fuel delivery system project was a fast-track, general construction opportunity unique in nature because it was the result of an emergency plant shutdown due to an explosion. The project required the perfect combination of efficient construction, improved safety features, process redundancy and additional fire protection. Greystone’s own tradesmen performed the metal building installation. The resulting fuel delivery system was constructed in less than 4 months and is capable of feeding biomass material at 12,000 cubic feet/hour.
Greystone Construction has partnered with Great River Energy (GRE) for more than 15 years on a wide range of projects that supports the reliable and safe operation of their waste-to-energy and resource recovery facilities. In the last 5 years, our collaboration has included projects of all sizes, from facility service work and tipping curb and floor repairs to pump house improvements and other critical maintenance efforts. In addition to service and repair projects, Greystone has delivered larger-scale construction solutions for GRE, including multiple pre-engineered metal buildings for shop buildings, dry storage, and ash storage loadout facilities.
Greystone constructed the Shakopee Energy Park, a 46 MW natural gas-powered generation facility developed for the Minnesota Municipal Power Agency (MMPA) in Shakopee, Minnesota and delivered in collaboration with Avant Energy. The facility features five 9.3 MW Wärtsilä engines designed for rapid startup, providing critical power supply flexibility and supporting the integration of renewable energy sources. Engineered with advanced sound attenuation and energy-efficient systems, the plant operates with minimal impact to the surrounding community.
Our construction timeline was very aggressive...yet the project hit this milestone due to creative scheduling by Greystone. They made sure that no time or opportunity for progress was lost throughout the project duration. Greystone demonstrated acute attention to detail throughout the construction process and went above and beyond with the detail on the final punch list.
