A study was conducted to determine the feasibility of restoring to service the deactivated Greggs Falls hydroelectric station in Goffstown, New Hampshire. Evaluation of technical, economic, legal, institutional, and environmental factors led to the conclusion that restoration was both feasible and attractive. The site can be restored for an investment of $2.1 to $2.4 million (depending on the operational mode) to establish 1.5 MW of capacity and produce 7945 MWh of electrical energy annually. Within 3 years, operation of the site can produce energy at lower costs than the cost of fuel oil in New England and will save approximately 14,600 barrels of fuel oil annually. The economic competitiveness of the facility is expected to improve with time because of the rising price of imported oil.
