Figure A1. Comparison of Nameplate to Net Summer Capacity, 1990-2013. Figure shows current discrepancy between installed nameplate capacity (design output of installed projects) to net summer capacity (net output of geothermal power available for sale during the summer). As of 2013, EIA survey data from geothermal generators shows that geothermal nameplate capacity was 3,765 MW in comparison to 2,607 MW reported net summer capacity. Sources: Energy Information Association (2015) Nameplate Capacity: Form 860 Generator Data, State Electricity Profiles (July 2015). Summer Capacity: Annual Energy Review (2015).
