The growth of renewable power, including wind and solar, has not harmed the reliability of the U.S. electricity grid, according to a draft U.S. Department of Energy study, echoing the findings of grid operators across the country.
The conclusion of the draft, dated July and viewed by Reuters, could ease fears in the renewable energy industry that the widely anticipated study would be used by President Donald Trump's administration to form policies supporting coal plants at the expense of wind and solar.
"Numerous technical studies for most regions of the nation indicate that significantly higher levels of renewable energy can be integrated without any compromise of system reliability," the draft says.
It added that growth of renewables could require the building of more transmission lines, advanced planning, and more flexibility to balance generation and meet demand. But it said that baseload power—coal and nuclear power—"is not as necessary as it used to be" given advances in grid technology.
