The Public Service of New Hampshire (PSNH) Northern Wood Power generates 50 megawatts of power using approximately 500,000 tons of clean, low-grade wood as fuel each year.  The low-grade wood consists of whole-tree wood chips, a material that would otherwise be wasted.

During the winter and spring months, deliveries of the wood chips can be delayed several days due to inclement weather conditions and traffic limitations on local roads.  Because of the limited on-site storage and the potential for suspended fuel delivery, PSNH retained Sanborn Head to develop additional wood chip storage at the site to seasonally bank fuel so that they may continue to reliably produce power when wood chip deliveries to the facility are reduced.
 
Working with PSNH, Sanborn Head engineered the desired storage on top of a former landfill located close to the generating plant.  Because the former landfill is bounded by overhead and below grade utilities, property lines, and wetlands, Sanborn Head’s design incorporated an innovative stormwater management approach, improved site truck access, a fire protection system, and visual barriers.  Sanborn Head prepared both city and state permit applications and the requisite engineering design, and assisted PSNH through the approval processes.
