The Commonwealth of the Northern Mariana Islands enacted its Renewables Portfolio Standard in September 2007, in which a certain percentage of its net electricity sales must come from renewable energy. Under the law, the Commonwealth Utilities Corporation (the Islands' only and semi-autonomous public utility provider) must meet the following benchmarks:
* 10% of net electricity sales by December 31, 2008
* 20% of net electricity sales by December 31, 2010
* 40% of net electricity sales by December 31, 2012
* 80% of net electricity sales by December 31, 2014
There are stipulations within the law that allow for non-compliance if there is no "cost-effective" way to meet the benchmarks. Overall, the standard is extremely aggressive and the Commonwealth Utilities Corporation is not in compliance.
In July 2011, National Renewable Energy Laboratory published the [http://www.nrel.gov/docs/fy11osti/50906.pdf Commonwealth of the Northern Mariana Islands Initial Technical Assessment Report] that includes additional information about energy, energy policy, and resources in the Northern Mariana Islands.
