This 2015 Solar Request for Proposals (2015S RFP) issued by PacifiCorp seeks Utah solar photovoltaic generation resources of up to fifteen (15) megawatts alternating current (MWAC) that are compliant with existing or anticipated renewable portfolio standards and that are new to PacifiCorp’s resource portfolio. Projects must meet the minimum size requirement of at least two (2.0) megawatts alternating current (MWAC) and each resource must be a discrete generating asset that can be individually metered and remotely monitored. Multiple smaller projects that are less than two (megawatts alternating current (MWAC) with a minimum aggregate size of two (2) MWAC will be considered. The 2015S RFP is to support Utah customers that wish to buy the output from Utah-based solar photovoltaic resources to meet a portion of their energy requirements. The resources must be located in Utah and interconnect with or demonstrate firm transmission service to Rocky Mountain Power’s transmission or distribution network (www.oasis.pacificorp.com).  PacifiCorp is seeking up to 15 MWAC in aggregate, with an expected on-line date of no later than December 1, 2016 in order to maximize the federal income tax benefits.
