The U.S. Department of Energy and the North Carolina Solar Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in the summer of 2014. Staff are currently working hard on the new DSIRE and are unfortunately only able to make minimal updates to the DSIRE website at this time. We apologize for any inconvenience and thank you for using DSIRE.

Summary:

Guam's Public Utilities Commission (PUC) reviewed net metering and interconnection during a regular meeting in February 2009 (Docket 08-10). Please contact the Guam PUC for the results of that docket review.

In 2004, Guam enacted legislation requiring the Guam Power Authority (GPA) to allow net metering for customers with fuel cells, microturbines, wind energy, biomass, hydroelectric, solar energy or hybrid systems of these renewable energy technologies. In 2010, Guam amended net metering and raised the system capacity limits to 25 kilowatts (kW) for residential systems and 100 kW for non-residential systems.*

GPA must provide customer-generators with a bi-directional energy meter and may, at its own expense, install additional meters. GPA may not charge customer-generators any fees above and beyond those it charges to other customers in the same rate class that do not use a net-metered energy system.

Net-metered systems must meet all applicable safety and power quality standards established by the National Electric Code, Underwriters Laboratories (UL) and the Institute of Electrical and Electronic Engineers (IEEE). The utility may not require customer-generators whose systems meet these standards to meet further requirements, install additional controls or purchase supplemental liability insurance.

Customer-generators may be billed on a monthly basis, or with their written consent, on a quarterly, semi-annual or annual period. If a system has produced net excess generation at the end of the billing period the customer-generator is entitled to compensation at a rate to be determined by the Guam Public Utility Commission (PUC). The PUC was required to adopt rules to implement net metering within 120 days of the effective date of the authorizing legislation. As of April 2008, the PUC has not adopted rules for net metering but is considering them through their work on an Integrated Resource Plan.


*Note: the original net metering law system capacity limit was 25 kW, regardless of customer class.
