Collection of Data, Dlsclaimers and Descriptions
Energy leaders have been identified based on public information about (a) their projected size, (b) status of permitting, (c) status of power or fuel off-take agreement, and (d) site control.* Pertinent data comes from a variety of media including company press releases, company websites, newspaper articles, Internet publications, agency notices, and filings with the Hawaii Public Utilities Commission.

This project list is not all inclusive – nor is it complete. In fact, we expect it will change continuously as additional public information becomes available and project status changes. The data we gather from public resources is assumed to be correct. Financial information is not included as part of the listing criteria as this information is often closely held and not readily available utilizing public resources. Attempts have been made by the Hawaii State Energy Office to call the respective project personnel and verify that the information has been publically reported, but the Energy Office cannot guarantee the accuracy or completeness of all data. This list does not represent an endorsement of any specific project or company. Finally, we are aware that some proposed renewable energy projects in Hawaii may be missing from the list simply because little or no public information is available at this time.

*Category descriptions:
1) Size is an important component as it indicates a projects overall potential renewable energy/fuel contribution to the State of Hawaii’s aggressive goals set forth by the Hawaii Clean Energy Initiative of 70% clean energy by 2030. Despite its importance, however, size is just one of the four categories considered in this listing as smaller scale projects are also demonstrating that they are advancing towards commercialization. Projected size is reported in megawatts (MW), kilowatt s ( kW) or gallons of fuel produced, based on the production capacity of each facility.
2) A power purchase agreement or contract to purchase an energy resource represents a future revenue stream for the specific project as well as validation that the energy resource is acceptable to the respective utility. The stages of the off-take agreement process range from ongoing negotiations with the utilities to executed terms sheets between utilities and projects, and finally, approval of the contract by the Hawaii Public Utilities Commission.
3) Permitting for projects is a necessary component before construction of a project can commence. This is a long and often arduous process, but is very indicative of a project’s progress towards commercialization.
4) A project’s control over the site of operations either through a long term lease or land acquisition demonstrates an important component to long term commercial sustainability and production.
