NEWS | issues and information | Renewable Resource Acquisition


The Public Utlities Commission (PUC) approved GPA's Integrated Resource Plan (IRP) in December 2008.  A primary strategic goal in the IRP is fuel diversification.  The IRP identifies several ways to introduce fuel diversification including Renewable Energy Resources.

The PUC has ordered the Authority to proceed with the IRP recommendation to acquire Renewable Resources.  Thus, GPA initiated its solicitation to acquire renewable energy resource in April 2008 by announcing the first of two phases to solicit proposals for renewable energy resources.  Acceptable renewable technologies in these solicitations include those technologies that meet the renewable resources definition by Energy Information Administration (EIA), a branch of the U.S. Department of Energy.

The following summarize the progress on GPA renewable energy acquisition. In addition links to related downloads and other sites are provided.

Phase 1
- updated 9/09/2014
Quantum Guam Power ("QGP") and Pacific Green Resources ("PGR") were awarded contracts for renewable energy, totaling 35MW in capacity.  The contracts were awarded based on proposals received for the GPA -027-11 Multi-Step Bid issued in 2011.  This was a second solicitation attempt after Multi-Step Bid (Bid No. GPA-038-09) was cancelled on November 30, 2009 due Public Law 30-66, enacted on November 27, 2009. 

Bid No. GPA-027-11 closed on June 1, 2011.  GPA evaluated and recommended contract award to the Consolidated Commission on Utilities and the Guam Public Utilities Commission.  Upon approval GPA initiated a system impact study which was completed in May 2012.  Contract signing for Quantum Guam Power for 20MW Solar Renewable Power Purchase Agreement was on June 27, 2012.  Contract signing for Pacific Green Resources for 15 MW total of Wind/Solar Renewable Power Purchase Agreements was on March 14, 2013. 

Since then Quantum Guam Power has acquired, through assignment, the 5.65MW Solar PPA from Pacific Green Resources. In addition, NRG Energy acquired Quantum Guam Power and the 25.65 MW total of PPAs on July 11, 2013.  Commercial operation for the initial 20 MW PPA is anticipated late September 2014 as extended.  The 5.65 MW PPA commercial operation date is March 2015.

PGR Wind PPA commercial operation date is slated for March 2016.

Phase 2 – Solicitation - updated 9/09/2014

GPA announced Phase II solicitation on July 1, 2014.  The Multi-Step No. GPA-059-14 package is available for download on the GPA Procurement webpage:

In this Phase II acquisition, GPA intends to acquire a total of 40 MW of renewable capacity that can meet the following established  requirements:

  • The Bidder’s resource technology meets the definition of “renewable resource” as described in bid document.
  • The renewable resource will be available for commercial operation within 60 months from the award of the contract.
  • The technology proposed for the renewable resource will have at least 1 year of commercial operations history in a utility environment.
  • The renewable resource will deliver energy directly to the existing GPA transmission system.
  • The renewable resource will provide energy for a minimum contract term of 10 years and a maximum contract term of 30 years.
  • The Bidder’s renewable resource project will have a total minimum nameplate capacity of 5 MW and a maximum nameplate capacity of 20MW; this may be the combination of several generation units at one site.

GPA intends to reserve the option to buy-out the capital portion of the contract and pursue alternative financing structures.  GPA seeks bids and proposals for “price competitive” renewable resources.   Please see instructions in the bid document and schedules concerning this solicitation. Bid proposals are due by 4:00PM on 10/03/2014 CHST (Chamorro Standard Time / Guam Time)
