Two states recently passed legislation that would require significant increases in renewable electricity generation. On June 8, Hawaii updated legislation setting a 100% renewable portfolio standard (RPS) by 2045. On June 11, Vermont passed a bill creating a 75% RPS by 2032. Both of these RPS target percentages are higher than any other RPS target in the United States.
, and an additional eight states have nonbinding renewable portfolio goals.
Hawaii’s previous RPS required 40% renewable energy by the end of 2030. The new policy, , includes interim requirements of 30% by the end of 2020, 40% by 2030, and 70% by 2040, ultimately reaching 100% renewable electricity by 2045. The state has met its annual RPS obligations to date, which for 2014 was 10% renewable energy. Largely because of its isolation, the bulk of Hawaii’s electricity generation continues to be from petroleum.
Before passing its RPS, Vermont ran a renewable goal program known as was retired. Because this plant supplied more than 70% of Vermont’s electricity generation in 2014, its retirement significantly changes the generation profile of the state.
The majority of state RPS policies were enacted in the late 1990s and early 2000s. Before Vermont’s RPS, the most recent RPS enacted was in 2009 when Kansas passed a renewable energy standard requiring 20% of the utilites’ peak demand to be met with renewable resources by 2020.
More recently, most of the states with existing RPS policies, such as Hawaii, have made major revisions to their original legislation. In some states, these changes have loosened or eliminated, rather than tightened, renewable standards. Last year voted to change the RPS that it created in 2009 to a nonbinding goal. A number of additional states currently have RPS legislation under review.
