Saco Valley Substation – Conway, NH

We expanded the existing Saco Valley Substation to facilitate the installation of two new General Electric Synchronous Condensers, steel building and associated electrical equipment. Foundation installation consisted of seismic mats for sync condenser, transformer foundations, oil containment systems and blast walls, circuit breaker foundations and a new 6,300 square foot building. GGC was also responsible for the installation of new conduit and precast concrete cable trench systems. The project also included drainage work, completion of bio retention ponds, new fencing and landscape restoration.
