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.

    The 3 Arguments Trump Used to Gut Greenhouse Gas Regulations

    Whether any of them will hold up in court is now the big question.

    Environmental lawyers are in for years of déjà vu as the Trump administration relitigates questions that many believed were settled by the Supreme Court nearly 20 years ago.

    On Thursday, Trump rescinded the “endangerment finding,” the Environmental Protection Agency’s 2009 determination that greenhouse gas emissions from vehicles threaten Americans’ public health and welfare and should be regulated. In the short term, the move repeals existing vehicle emissions standards and prevents future administrations from replacing them. In the longer term, what matters is whether any of the administration’s justifications hold up in court.

    Washington Wants Data Centers to Bring Their Own Clean Energy

    The state is poised to join a chorus of states with BYO energy policies.

    With the backlash to data center development growing around the country, some states are launching a preemptive strike to shield residents from higher energy costs and environmental impacts.

    A bill wending through the Washington State legislature would require data centers to pick up the tab for all of the costs associated with connecting them to the grid. It echoes laws passed in Oregon and Minnesota last year, and others currently under consideration in Florida, Georgia, Illinois, and Delaware.

    Michigan’s Data Center Bans Are Getting Longer

    Plus more of the week’s top fights in renewable energy.

    1. Kent County, Michigan — Yet another Michigan municipality has banned data centers — for the second time in just a few months.

    • Solon Township, a rural community north of Grand Rapids, passed a six-month moratorium on Monday after residents learned that a consulting agency that works with data center developers was scouting sites in the area. The decision extended a previous 90-day ban.
    • Solon is at least the tenth township in Michigan to enact a moratorium on data center development in the past three months. The state has seen a surge in development since Governor Gretchen Whitmer signed a law exempting data centers from sales and use taxes last April, and a number of projects — such as the 1,400-megawatt, $7 billion behemoth planned by Oracle and OpenAI in Washtenaw County — have become local political flashpoints.
    • Some communities have passed moratoria on data center development even without receiving any interest from developers. In Romeo, for instance, residents urged the village’s board of trustees to pass a moratorium after a project was proposed for neighboring Washington Township. The board assented and passed a one-year moratorium in late January.

    2. Pima County, Arizona — Opposition groups submitted twice the required number of signatures in a petition to put a rezoning proposal for a $3.6 billion data center project on the ballot in November.
