LIHI Certificate #136 – New Home Dam Project, Massachusetts

The first Dam at the New Home Dam site was in built in 1790 and was used for grist and saw mill. New Home Sewing Machines rebuilt the dam in 1877 and 1891. Chase Turbine moved to Orange in 1865 and occupied a small shop at in the New Home Sewing Machine Company Works. When ACOE prepared the Connecticut River Flood Control Profile in 1940, Chase Manufacturing was the owner of the Dam and therefore is recorded as such on the Profile plan. The State designed and built the current dam beginning in 1939. The site was redeveloped for the current use in the 1980’s by Mini-Watt Electric Company Inc. The facility was purchased by O’Connell Development Inc. in 1994 and has been operated by O’Connell since that time.

The New Home Dam has a FERC Exemption P-6096-MA issued 12/28/1984. The Project operates in run-of-river mode with a minimum flow of 152 cubic feet per second (CFS) or inflow be passed through the project at all times including 10 cfs flow to the bypass reach. The project dam is classified as a low hazard potential structure. The impoundment has a reservoir surface area of 106 acres and storage capacity of 530 acre-feet. The 1984 FERC Exemption for the project included the original (1940) North Riverbank Powerhouse with a 175 kW turbine/generator and the development of the 1984 South Riverbank Powerhouse with two (2) used 120 kW turbine/generators in the location of a previous mill building. An Amendment granted on 8/2/2010 to replace the T3 propeller turbine unit (located in the south powerhouse) with installed generator capacity of 120 kW with a new Kaplan unit with 160 kW capacity. Current Project installed capacity is 455 kW.
