Does an Island Approach to Higher Penetration Renewables Make Sense for the Mainland?

Research output: NRELPresentation

Abstract

Does an Island Approach to Higher Penetration Renewables Make Sense for the Mainland? The US currently generates ~8% of its electricity from wind and solar. There are goals to get to 20% wind by 2030 and PV looking to be cost competitive at all sizes with similarly high penetration goals. Islands, such as Kaua'i and Guam, have much higher renewable energy goals. Kaua'I had a 50% RE goal by 2023, now they want to be 70% RE by 2030. Guam Power Authority (GPA) had a goal of 25% by 2035. They now have a goal of 50% by 2028. How have they/will they achieve these goals? Are there lessons learned from these smaller, island grids that can be applied to larger states, regions, or balancing authorities? This presentation will examine how these two island utilities have made such progress.
