Exploration Basis
After 1983, several full sized production and injection wells were drilled within the caldera to the east of Highway 395.
 
Notes
These included two injection wells (IW-1, IW-2) and four production wells (MBP-1, 2, 3, and 5) drilled at Casa Diablo to support the MP-I geothermal power plant, a joint venture between Mammoth Binary Power Company and Pacific Energy Resources Inc.[1] [2] [3] These wells exhibited temperature profiles similar to that encountered in the upper 300 m of (Unocal) Mammoth-1. Successful construction of the MP-I power plant in 1985 by Kennebec Construction Company (a subsidiary of The Ben Holt Co., who designed the facility) marked the completion of the world's first air-cooled binary cycle geothermal power plant.[4]
