More than 147 MW of gross geothermal capacity was brought online in 2012, an increase of 5 percent from 2011, according to the Geothermal Energy Association. Geothermal accounted for about 3.5 percent of renewable energy in the U.S., according to the U.S. Energy Information Administration (EIA).
Nine states brought geothermal plants and small power units online last year, including California, Nevada, Alaska, Hawaii, Idaho, New Mexico, Oregon, Utah and Wyoming. California now has more than 2,700 MW of installed geothermal capacity according to preliminary GEA results.
The capacity added in 2012 would meet the residential needs of a city the size of Vancouver, Washington or Kansas City, Kansas. Projects and new additions that came online in 2012 include:
· John L. Featherstone Plant (California): Energy Source, 49.9 MW
· McGinness Hills (Nevada): Ormat, 30 MW
· Neal Hot Springs (Oregon): U.S. Geothermal, 30.1 MW
· San Emidio I (Nevada): U.S. Geothermal, 12.75 MW
· Tuscarora (Nevada): Ormat, 18 MW
· Dixie Valley I (Nevada): Terra-Gen, 6.2 MW
· Florida Canyon Mine (Nevada): ElectraTherm, 0.1 MW
In addition to these seven projects, GEA identified 13 geothermal companies with projects in stage 3 or 4 of development. Some of these projects are expected to come online in 2013.
