On August 29, 2005, A&D Hydro, Inc. submitted an application for certification of its West Springfield Project on the Westfield River.

The West Springfield Project is located in the Connecticut River Basin. The Connecticut River is the largest river in the New England states. It extends about 400 miles from its origin in Fourth Connecticut Lake, New Hampshire, at an elevation of 2,625 feet, to Saybrook, Connecticut, where it empties into Long Island Sound. The tidal portion of the river extends from Long Island Sound to a point 60 miles upstream (Enfield Rapids).

The Connecticut River is a highly developed resource with many projects in the smaller tributaries of northern Massachusetts, Vermont, and New Hampshire. At present, there are 109 existing hydroelectric developments in the Connecticut River Basin. Because of their upstream location and remoteness, however, these projects have no effect on the West Springfield Project.

The Westfield River is a major tributary of the Connecticut River. The Westfield and Connecticut Rivers confluence is about 7 miles north of the Massachusetts/Connecticut border. Ground elevation at the confluence of the Westfield and Connecticut Rivers is about 48 feet msl.

The West Springfield Project consists of : an 18-foot-high, 447.5-foot-long timber crib dam with a dam crest elevation of 92.80 feet above mean sea level (msl) that creates a 20-acreimpoundment; a 2,610-foot-long, 50-foot-wide power canal with concrete headworks containing six gates; a concrete and brick powerhouse about 60 feet long, 54 feet wide, and 63 feet high containing two vertical Francis turbines connected to two 480-volt generators; and a tailrace approximately 157 feet in length and having a width varying from 30 to 48 feet. There are no primary transmission lines included in the project.

Unit One is rated at 900 kilowatts (kW) and Unit Two is rated at 466 kW. However, due to flow restriction in the power canal, the combined capacity is 1,200 kW (Unit One at 800 kW and Unit Two at 400 kW). The project's average annual generation is 5.5 gigawatt-hours (GWh).

The project currently operates as a run-of-river facility (inflow equals outflow instantaneously). The hydraulic capacity of the project is 622 cubic feet per second (cfs) (400 cfs for Unit One and 222 cfs for Unit Two). The adjacent Southworth Company also draws water from the power canal to operate their own generating facility. When DSI's facility is not operating and inflows are below the hydraulic capacity of the turbines used by the Southworth Company, all inflow is spilled at the dam.
