FACTB0X-U.S. states with renewable power targets

June 12 (Reuters) - Twenty-nine of the 50 U.S. states have established a required minimum amount of electricity generation that must come from renewable sources like wind and solar power, called a Renewable Portfolio Standard or RPS.

Another five states have “renewable goals” which are considered voluntary and do not penalize utilities for not meeting the goals.

The District of Columbia also has an RPS.

California’s utility regulator, the Public Utilities Commission, issued a report on Friday that showed that requiring a third of the power delivered in the state be made from renewable sources of energy will increase electricity retail costs by 7 percent more than having a 20 percent RPS goal.

Green advocates want a national renewable portfolio standard to foster faster growth of renewable energy.

The following list is not a direct comparison because the definition of renewable power varies by state.

Comparisons may not be proportional, either. For instance, Maine and New York allow large hydropower generation to be included even though those resources -- like power plants near Niagara Falls - have been in operation for decades.

California and other states do not allow large hydropower projects to be included because they do not reflect growth of renewable power. Large U.S. hydropower projects are considered a mature source of energy and are not significantly expanding.

Nuclear power counts toward renewable energy goals in only one state, Ohio.

The following table shows states with renewable energy portfolio standards, compiled by researchers at North Carolina State University, and the Pew Center.

e- Texas 5% 2015

Washington, D.C. 20% 2020

Washington 15% 2020

Wisconsin 10% 2015

The following states have voluntary goals:

North Dakota 10% 2015

South Dakota 10% 2015

Utah 20% 2025

Vermont 25% 2025

Virginia 12% 2022

States without RPS or voluntary goals:













South Carolina


West Virginia


a - Colorado has set 20 percent goal for investor-owned utilities by 2020 and 10 percent for municipal and cooperative utilities by 2020.

b - Maine set 30 percent by 2000 and beginning 2008 to increase renewable power by 1 percent annually.

c - Investor-owned utility Xcel is to have 30 percent renewables by 2020 in Minnesota.

d - Ohio can reach its goal by including some energy efficiency programs and counting third-generation nuclear power plants.

e- Texas has called for increase of 5,000 MW over the 1999 renewable generation level by 2015. That is about 5 percent of the state’s power generation.

A megawatt, by U.S. average, can power 800 to 1,000 homes, but the number is lower for areas with high air-conditioning use, such as Arizona and Florida, where a megawatt can power about 400 homes. (Reporting by Bernie Woodall; Editing by Richard Chang)
