New federal environmental regulations call for substantial emissions reductions from U.S. power grids. For a system designed for fossil fuel resources, this will mean transforming the grid to accommodate large increases in renewable energy resources. Opponents of such regulations claim that the integration of these resources will impose high costs on the system, in particular those related to maintaining reliability standards. A new Synapse study finds that these claims are overblown, and that the costs to integrate increased amounts of wind and solar energy are minimal. Actual costs found by integration studies across the country are on the order of half a cent per kilowatt-hour of energy the resource produces, according to the Synapse literature review.
