America Is Depending on Renewables This Summer

It’s a clear sign that wind and solar power really matter.

The weather is changing and there are concerns about the reliability of the electric grid. This is a story that can be written at least twice a year and often is. Whether it’s cold snaps knocking off generation or everyone cranking up the air conditioning, more extreme weather means it’s harder to match the supply and demand of electricity.

Earlier this week, the North American Electric Reliability Corporation, which sets and enforces standards for grid operators in the United States and Canada, released its annual Summer Reliability Assessment, reporting that while it expected the grid to make it through unscathed, still “two-thirds of North America is at risk of energy shortfalls this summer during periods of extreme demand,” i.e. if it gets really, really hot.

And every year renewable energy skeptics use the report to blame the increased use of renewables and retirement of fossil fuel generation for the brittleness of the grid.

NERC both pre-empts and acknowledges such criticism this year. “Increased, rapid deployment of wind, solar and batteries have made a positive impact,” NERC’s manager of Reliability Assessments Mark Olson said in a statement accompanying the report. “However, generator retirements continue to increase the risks associated with extreme summer temperatures, which factors into potential supply shortages in the western two-thirds of North America if summer temperatures spike.”

More deeply, though, these worries are just a clear sign of the progress the renewables buildout has made, even before last year’s passage of the Inflation Reduction Act.

The interconnected grids of the United States and Canada are now clearly reliant on renewable and non-carbon generation, from utility-scale solar in the Mojave Desert to wind farms in Oklahoma to nuclear power plants in Ontario. This summer (and every summer after it) will be put up or shut up time for an increasingly renewable-heavy grid.

In short, the renewable buildout, while far from complete, has begun to work. Some 400 million people are, in one way or another, dependent on these resources to keep the lights on.

And when it comes to dealing with potential extreme weather in the summer, all eyes are on wind. In the Midwest and Southwest, the NERC report isolates wind power as a "key factor" in whether the grid will function when demand rises.

In Texas, which is debating subsidizing the construction of new natural gas plants to deal with winter reliability issues, the report notes that, while “resources are adequate for peak demand of the average summer," it worries about "an extreme heat-wave that is accompanied by low winds.”

  • In the Western United States, NERC called out the familiar issues of vast solar resources disappearing at the end of the day while demand is still high, but noted that there are plans for large-scale batteries to essentially store sunlight for later in the day. NERC, as well as California’s grid operator, also said the massive snowfall this winter will boost generation by the region’s hydropower, a welcome reversal of the typical negative effects extreme weather has on the grid.

    All of this by no means indicates that fossil fuels are out, even as coal is forecast to fall to just 16 percent of overall electricity generation by 2024, according to the Energy Information Administration. And natural gas is "vitally important to electric grid reliability,” the NERC report says.

    But even natural gas’ portion of the country’s electricity generation may have peaked. The EIA expects natural gas to make up 40 percent of electric generation this year and to decline to 38 percent in 2024, while renewables will rise from 23 to 26 percent of generation.

    In the race between the atmospheric carbon dioxide contributing to extreme weather and the carbon-free generation designed to reduce new emissions, the carbon is still winning, but the renewables are at least off the starting blocks. Now it’s time to see if they can maintain their stride.

    What’s So Weird About Trump’s Offshore Wind Payouts

    The president has paid $4 billion to kill projects that were already dying or dead.

    At a certain level, it defies belief: The Trump administration is spending nearly $4 billion … for nothing.

    It’s paid something for nothing at least five times now. Last week, the administration reached a $1.2 billion deal with the German energy company RWE to not build three wind farms, including a large installation off the coast of New Jersey. The Chicago-based developer Invenergy signed a separate deal in June. It’s not clear these deals are legal, yet they keep happening.

    Governors Are Ratepayer Advocates Now

    As electricity prices rise, the stakes for the leaders of states like Virginia, Pennsylvania, and Indiana are only getting higher.

    Governors are increasingly throwing their weight around in the technocratic and often obscure utility ratemaking process. The latest example is Virginia Governor Abigail Spanberger, who last week published a Washington Post op-ed announcing that she would intervene in the attempted acquisition of the state’s dominant utility, Dominion, by Florida utility and energy development company NextEra Energy.

    Spanberger is “deeply skeptical about whether selling our primary state-regulated utility to an out-of-state company is good for the commonwealth,” she wrote. While she didn’t go so far as to oppose the merger, she did insist that NextEra maintain jobs in the state, comply with Virginia’s clean energy goals, and come up with cost savings for Virginians. And while the state’s utility regulators will make the ultimate decision themselves, she said, she wanted to use her leverage as the state’s highest ranking and most visible elected official “to make sure Virginians have a voice in the process.”

    Trump’s USDA Using Farmland Rule to Go After Energy Companies, Democrats Say

    A proposed change in how the agency implements an obscure Cold War-era law would impose onerous reporting requirements on renewables and pipelines.

    Democrats in Congress claim that a new Trump administration proposal will have a chilling effect on the energy sector by subjecting renewables and fossil fuel pipelines alike to an obscure, rarely cited Cold War-era law requiring detailed information on foreign farmland ownership be submitted to the Agriculture Department.

    In late June, the Agriculture Department released a proposal to change implementation of the Agricultural Foreign Investment Disclosure Act of 1978, which requires companies to provide information to the federal government on foreign investors in farmland holdings, acquisitions, and sales. If finalized, the new rule would expand the definition of “agricultural land” in regulation to include all renewable energy facilities and pipeline corridors by explicitly tying the term to those industries’ formal codes under the North American Industry Classification System.
