Large wind projects in Vermont

Here is an outline of the current industrial-scale wind projects targeted for Vermont. Note the huge leap in size from the existing Searsburg facility that we are all urged to go see and love and love as well the new very much larger facilities being planned.

size data provided:
number of towers × rated capacity of each turbine = capacity of facility
height = hub height + blade length (r); area swept by blades of each turbine (πr2) = x acre(s)

Existing:

Searsburg (1996) -- Enxco & Green Mountain Power
  • 11 × 555-KW = 6 MW
  • 198' = 132' + 66'; 12,868 ft2 = 0.30 acre

Planned:

Searsburg expansion -- Enxco & Green Mountain Power
  • 20-30 × 1.5-MW = 30-45 MW
  • 340' = 213' + 127'; 50,273 ft2 = 1.16 acres

East Mountain (East Haven) -- Mathew Rubin
  • 50 × 1.5-MW = 75 MW
    (4 × 1.5-MW = 6 MW demonstration project currently in permitting process)
  • 335' = 220' + 115'; 41,548 ft2 = 0.96 acre

Glebe Mountain (Londonderry) -- Catamount Energy
  • 27 × 1.5-MW = 48.6 MW
  • 387' = 256' (78 m) + 131' (40 m); 5,027 m2 = 1.24 acres

Lowell Mountain -- Enxco & Vermont Public Power Supply Authority
  • 12-26 × 1.5-MW = 18-39 MW
  • 328' = 212' (64.7 m) + 116' (35.25 m); 3,904 m2 = 0.96 acre

Hardscrabble Mountain (Sheffield) -- UPC Wind Partners
  • total 30 MW (per American Wind Energy Association)
  • 3 × 131' (40 m) measurement towers approved by Public Service Board, 1 currrently erected

Mt. Equinox (Manchester) -- Endless Energy
  • 5 × 1.5-MW = 7.5 MW
  • 330' = 200' + 130'; 53,093 ft2 = 1.22 acres

Nearby:

Hoosac Range (Florida & Monroe, Mass.) -- Enxco
  • 20 × 1.5-MW = 30 MW
  • 340' = 213' + 127'; 50,273 ft2 = 1.16 acres

Gardner Mountain (Lyman, N.H.) -- UPC Wind Partners
  • 20 turbines
  • 158' measurement tower proposed
