PLU: Geothermal Power Production GPD: Resource Extraction

Document Description
Note: Extended per lead The proposed project would replace the aging MP-1 geothermal power plant with a new, more modern and efficient binary power plant (referred to as "M-1") while maintaining the existing geothermal wellfield, pipeline system and ancillary facilities. No new offices or other structures are proposed, with the exception of a small substation to be placed on the north side of the project site. The M-1 plant would be located approximately 500 feet east of the existing MP-1 plant. The M-1 replacement power plant is anticipated to increase the net electricity generation by 34% while utilizing the same geothermal resources for the existing MP-1 facility. During M-1 plant startup operations, the existing MP-1 plant would continue to operate until the new M-1 plant becomes commercial, after which time the applicant would close and dismantle the old MP-1 plant becomes commercial, after which time the applicant would close and dismantle the old MP-1 plant and would utilize the former plant location for equipment storage. The transition period during which both the MP-1 and M-1 operations would overlap would be a maximum of two years from the date the M-1 plant begins startup operations.
