Guam Bill 166, enacted in March 2008, established a renewable energy portfolio goal of 25% renewable energy by 2035.* Under this law, each utility that sells electricity for consumption on Guam must establish a renewable portfolio goal according to the following schedule:

  • 5% of net electricity sales by December 31, 2015
  • 8% of net electricity sales by December 31, 2020
  • 10% of net electricity sales by December 31, 2025
  • 15% of net electricity sales by December 31, 2030
  • 25% of net electricity sales by December 31, 2035

Additionally, any permit issued for the construction of a base load electrical generation plant must include a requirement that 10% of total generation capacity must come from "alternative" energy sources. The production of alternative energy generation in these plants must also be brought on line at the same time as production from traditional sources. It should be noted that Guam Power Authority (GPA) is the only power utility on Guam.

This bill also authorizes the Guam Public Utilities Commission (PUC) to issue recommendations for the implementation of a utility rate structure designed to reward and encourage consumers to use renewable energy and ensure that utilities' profit margins do not decrease for a period of five years following implementation of this rate structure. The PUC is also charged with designing incentive proposals and further legislation which could be offered to encourage utilities to meet the renewable portfolio goal.

The GPA's Integrated Resource Plan (IRP) was approved by the PUC in December of 2008. This plan includes considerable attention to the renewable portfolio goals. One of the primary recommendations within the plan is to procure wind (or other renewable energy) projects by the end of 2009, which will help the GPA meet the RPS goals. The GPA issued its first request for proposals in January 2011 and a second one in early 2012.

* A renewable portfolio goal generally is not legally binding, as opposed to a renewable portfolio standard, which is legally binding.
