Welcome to the new Islanded Grid Resource Center


Learn about the Islanded Grid Resource Center

Connect with your colleagues working on island energy systems.

Successful wind power deserves a collective approach. Use this site to learn about wind power systems and connect with researchers, system operators, government leaders and others around the U.S. and world working on energy solutions for islands and islanded grids.

Areas of focus

The Resource Center’s three main focus areas are: Wind-Diesel Systems, Megawatt-Scale Wind Systems on Islanded Grids, and supporting island communities in close proximity to proposed commercial-scale offshore wind and other ocean energy projects. Through the links on this site, you can find profiles on existing and proposed wind systems, reports and discussion on technological and other developments, and connections to wind system operators and technical experts.


Wind-diesel hybrid systems exist in island and remote communities in Alaska, Hawaii, and New England as well as in Canada, Australia, and even Antarctica. By pairing existing diesel engines with wind turbines, communities can reduce their use of expensive (and often imported) fossil fuel. This technology is growing in use, and is continually being developed and refined.

Large islanded grids are megawatt scale or larger wind farms located on islands such as Hawaii, or on “islanded grids” that are islanded in the sense they are not tied into any other grids. The “Railbelt” grid in Alaska that serves the state’s largest city Anchorage is an example of an islanded grid. Technical hurdles such as utility acceptance, permitting, and financing have often been significant for these systems as well as integration and load balancing.

As the U.S. offshore wind industry develops, many island communities, particularly along the Eastern Seaboard, have become involved in discussions around siting, impacts and benefits of projects proposed in nearby waters. These communities are engaging with developers, regulators, industry experts and others in order to understand the implications of offshore wind development for their communities and to ensure their voices are heard in the decision-making processes around siting, construction, power offtake, and community benefits for offshore wind projects.
