HP Hood is a major dairy manufacturing company. Hood pursued a cogeneration plant to reduce their carbon dioxide emissions, increase energy savings, and provide electrical resiliency for their facility. Z&F Construction provided design-build services as the prime contractor. The plant incorporated a 14.5MW combustion turbine, two 30,000 lb heat recovery steam generators, and a 600 hp natural gas compressor. The project also included a new 13kV substation. This gave the facility the ability to operate in island mode.
Z&F Construction utilized Z&F Consulting as the lead design firm. Z&F Consulting completed the mechanical and electrical design from conception to completion. This project was able to reduce carbon dioxide emissions by 42%. The project is currently pursuing PEER Certification through the GBCI.
Part of this project was creating the interconnection to allow Hood to sell excess power back to the grid through PJM. Z&F is a PJM member, and has fully automated the process for when to operate the plant so that excess power can be sold at a profit. This also allowed Hood to operate the plant such that their capacity and transmission charges from the utility are almost zero. This resulted in significant cost savings for Hood.
