PacifiCorp’s 2020 All-Source Request for Proposals

PacifiCorp’s 2019 IRP preferred portfolio includes new wind, solar, and battery energy storage systems (BESS) collocated with new solar resources. PacifiCorp’s IRP preferred portfolio included 2,380 MW of new solar resources collocated with 595 MW of BESS capacity and 1,920 MW of new wind resources.

Under 2020AS RFP, PacifiCorp is seeking proposals for competitively priced resources capable of interconnecting with or delivering to PacifiCorp’s transmission system in its east or west balancing authority areas (PACE and PACW, respectively).  

The 2020AS RFP will consider bids that can achieve commercial operation by December 31, 2024. In addition, PacifiCorp will accept bids from pumped storage hydro and nuclear resources requiring longer lead time to develop and construct that places the project completion beyond December 31, 2024.

PacifiCorp is currently finalizing its draft RFP and schedule which it expects to submit to Utah and Oregon Commissions and stakeholders in April 2020 for review, comment, and approval.  PacifiCorp expects to release the RFP to market in early July 2020.

On January 31, 2020, PacifiCorp Transmission filed an application with the Federal Energy Regulatory Commission (FERC) proposing to reform its interconnection study process set forth in its Open Access Transmission Tariff (OATT). The filing has been assigned to FERC Docket No. ER20-924-000. The filing proposes to replace the existing “serial queue” interconnection study process with a “first-ready, first-served, cluster” interconnection study approach. The company’s existing “serial queue processing” interconnection study process remains in effect until FERC approves PacifiCorp’s interconnection queue reform.  However, in anticipation that FERC will timely approve PacifiCorp’s proposed interconnection queue reforms, the draft 2020AS RFP that is planned for submittal to the Utah and Oregon commissions and stakeholders will assume that PacifiCorp’s proposed interconnection queue reforms are accepted by FERC prior to official release of the 2020AS RFP.  In the event that PacifiCorp’s interconnection queue reform application is not approved in time for the 2020AS RFP release, PacifiCorp will proceed under PacifiCorp transmission’s current interconnection queue process as described in its OATT posted on its OASIS site, and will revise the 2020AS RFP accordingly.

As such, potential bidders into PacifiCorp’s upcoming 2020AS RFP should review and clearly understand PacifiCorp’s interconnection queue reform application filed on January 31, 2020 as posted to PacifiCorp’s OASIS site (  Specific attention should be paid to the specific steps, eligibility criteria, milestones, and schedule of PacifiCorp Transmission queue reform and transition cluster study process.

Two Independent Evaluators (IEs) will provide oversight services on the 2020AS RFP for the Public Service Commission of Utah and the Public Utility Commission of Oregon.  Further detail on contact with the IE will be posted as it becomes available.
