R&W was commissioned to assist with the electrical power, lighting, and automation systems of a new processing plant to produce wood pellets and briquettes for wood burning stoves and wood based water boilers.

This project had substantial ARRA funding and resulted in new jobs for the Central Oregon town of John Day. R&W developed and designed the entire power supply system design for all equipment including chip receiving, chip drying equipment, chip size reduction with grinders, final dry chip storage, reclaim conveyance to two briquette machines, a palletizing mill, provisions for a future pellet mill, and final pellet mill storage and truck loading system. R&W developed and designed a PLC based automation system for the entire plant. R&W provided all automation software development and performed all on-site start-up testing and commissioning. Project had a short time schedule and R&W assisted with the advance purchase of all major electrical equipment and automation equipment. As a result, with a start of design in March, the plant was built and operational by December of the same year.
