KGRA Energy's system uses the organic Rankine cycle to recover waste heat from viable sources, such as combustion engine exhausts, furnaces, boilers, and kilns, converting it into usable carbon dioxide-free electricity, which lowers energy costs and heat pollution.  KGRA's systems are modular and scalable, providing the ability to produce power from smaller and lower-temperature heat sources previously deemed unsuitable for standard cogeneration. KGRA projects are customized for the direct needs and specifications of each customer. At the Weyerhaeuser lumber mill, heat will be recovered from a kiln where cut lumber enters the drying process.

The organic Rankine cycle equipment that will be installed in Weyerhaeuser's Greenville lumber mill will be made in America. Additionally, the project is expected to create 19.7 American jobs throughout the development, construction, and installation process.

Weyerhaeuser and Ayden HTP Partners LLC, a joint-venture between KGRA Energy and the ORC equipment supplier, TAS Energy LLC, a subsidiary of Turbine Air Systems, LTD, completed the agreement in March 2011. Installation of the project is expected to begin in June and the plant intends to be operational by the end of July 2011.
