Europe could teach America a thing or two about interconnection.
As the invasion of Ukraine raged last year, all eyes were on Europe’s power grid. Gas prices skyrocketed, Scandinavia’s water levels fell, and France’s trusty nuclear power plants went offline. It was a test of whether the world’s most interconnected energy grid could keep the lights on under extreme stress — and Europe passed. Today, as increasingly volatile weather patterns wreak havoc on infrastructure, the grid is proving to be more important than ever.
“Climate change is going to make us rely on the grid more,” Michael Pollitt, a professor of economics at Cambridge and an expert in energy economics, told me. “It’s not just gas price effects across Europe, it’s low water years and low wind years that will have impacts everywhere.”
This summer’s extreme heat could have been the next greatest threat to the power grid following the invasion of Ukraine. But instead, the stresses posed by recent weather have shown the strength of Europe’s power grid, proving the importance of interconnection in an era of global warming.
Europe’s power grid is made up of a series of interconnected localized grids. The primary one is the continental grid, where about 15% of the continent’s energy is traded across borders every year. This grid serves 400 million consumers across 24 countries, including most of the European Union countries, plus the Balkans and Turkey. These 24 countries are also connected to several other grids: the Nordic grid, the British grid, the Irish grid, and, as of August this year, the Baltic grid. Those additions bring electricity to more than 600 million consumers. In addition, there are discussions about connecting North Africa’s power grid, and especially Morocco, which would provide a rich source of solar energy.
Each country invests in what they do best: Norway champions hydropower, France has nuclear power plants, the U.K. invests in wind turbines, Spain does solar, etc. And each one can sell the excess energy to the grid to assist other countries. When water levels are low in the summer months, Norway relies on countries like Spain, who have ample power from their solar fields. In the cloudier winter months, Norway returns the favor. There is a call for faster progress on interconnection and transmission to make this into an even more reliable “Super Grid.”
This tool provides an interactive map of the grid today, and the expected changes up until 2040.
This single market allows for an energy security not seen in the United States, which has several disconnected state or regional grids with much more limited interconnection. This not only restricts the distribution of renewable energy in the U.S., but it can lead to blackouts, most famously in Texas in 2021.
One reason that Europe’s grid has proved remarkably resilient is that mutual reliance also means mutually assured destruction.
“If a country were to reduce exports, it would reduce costs in their country,” said Pollitt, referring to fears last year that European countries would unplug from the interconnected grid to safeguard their own energy supplies. “But you barely think about that for too long before you realize it’s a nuclear option to keep prices down.”
EU countries came together to agree on a gas price cap to contain the energy crisis in December 2022. But the rise in gas prices was a powerful incentive for countries to increase their reliance on renewables. Wind and solar generated 10% more energy compared with the same period in 2021-2022, saving the region 12 billion euros in gas imports (about the same in dollars), according to Ember, an energy think tank.
“I’m very happy to see European solidarity manifest itself and be resilient even though there was some temptation to go it alone,” Kristian Ruby, the secretary general for Eurelectric, the association for the electricity sector in Europe, told me. “By standing together and doubling down on solutions, we’ve seen them keep the lights on during an extremely difficult time.”
Extreme weather is the next big hurdle for the grid to overcome. “There’s no doubt that extreme weather events are becoming a strain on electricity operators,” said Ruby. A recent report from Eurelectric says that all power systems are exposed to the effects of extreme weather, including generation, transmission, and distribution. For hydropower, low water levels are detrimental and extreme cold can cause ice and blockages. Geothermal and nuclear energy become less efficient during heat waves because they require water and cold air for cooling. Many of these plants are also vulnerable to coastal and inland flooding.
This summer in particular, the grid was put to the test. Extreme heat in Spain and Italy pushed the grid to its upper limit. Using power from places like Britain, Norway and Switzerland, Spain was able to provide the power needed. It also benefited from investments in solar panels, which supplied 20 percent more solar power than in the summer of 2022.
The grid’s strength is in its variability. “Different types of weather phenomena call for different coping strategies. Resilience is about diversity. It’s about having a mix of different things. One technology will not solve it alone,” said Ruby.
Renewable energy sources differ based on the conditions in which they are built, which can make the electricity supply more adaptable. If there’s enough interconnection to bring power from, say, where it’s sunny or windy to where it’s needed, countries are much less likely to experience blackouts during severe weather. Whereas with fossil fuel based energy like coal plants, the energy supply is concentrated and more susceptible to shocks.
Despite the success, some experts are concerned that transmission isn’t growing fast enough to handle electrification. People are buying more heat pumps and using electric vehicles, but NGO WindEurope says that the grid itself is not expanding at the same pace. Experts also say that as loads increase, electricity flows will become more complex. Ruby advocates more digitalization in order to handle these complex flows.
The EU Commissioner for Energy Kadri Simson wrote an op-ed piece in the Financial Times this month saying that Europe must sustain a fast pace in rolling out renewables and electrifying the economy. She references the need to integrate intermittent renewable power and adapt more decentralized electricity systems. She says the emphasis needs to be on transmission and distribution grids.
The EU reduced the length of time needed for permitting electricity transmission. It also introduced new emergency legislation last year to accelerate the authorization of renewable projects.
Despite concerns about pace, experts seem generally optimistic about the EU's grid. “EU energy and climate policy are really a success story in European coordination and interdependence,” said Pollitt.

Current conditions: Thousands are without power and drinking water in the French Indian Ocean territory of Réunion after Tropical Cyclone Garance made landfall with the strength of a Category 2 hurricane • A severe weather outbreak could bring tornadoes to southern states early next week • It’s 44 degrees Fahrenheit and sunny in Washington, D.C., where Ukrainian President Volodymyr Zelenskyy will meet with President Trump today to sign a minerals deal.
The 16th United Nations Biodiversity Conference, known as COP16, ended this week with countries agreeing on a crucial roadmap for directing $200 billion a year by 2030 toward protecting nature and halting global biodiversity loss. Developed nations are urged to double down on their goal to mobilize $20 billion annually for conservation in developing countries this year, rising to $30 billion by 2030. The plan also calls for further study on the relationships between nature conservation and debt sustainability. “The compromise proved countries could still bridge their differences and work together for the sake of preserving the planet, despite a fracturing world order and the dramatic retreat of the United States from international green diplomacy and foreign aid under President Donald Trump,” wrote Louise Guillot at Politico. The decision was met with applause and tears from delegates. One EU delegate said they were relieved “about the positive signal that this sends to other ongoing negotiations on climate change and plastics that we have.”
The Trump administration yesterday fired hundreds of workers across the National Oceanic and Atmospheric Administration and the National Weather Service, key agencies responsible for monitoring the changing climate and communicating extreme weather threats. The National Hurricane Center and the Tsunami Warning Center both operate under NOAA, and the layoffs come ahead of the upcoming hurricane season. “People nationwide depend on NOAA for free, accurate forecasts, severe weather alerts, and emergency information,” said Democratic Rep. Jared Huffman, the ranking member of the House Natural Resources Committee. “Purging the government of scientists, experts, and career civil servants and slashing fundamental programs will cost lives.” A federal judge yesterday temporarily blocked the administration’s mass firings of federal workers, so the status of those affected in this latest round is unclear. Somewhat relatedly, Heatmap’s Jael Holzman reports that the Nature Conservancy, an environmental nonprofit, was told by NOAA it had to rename a major conservation program as the “Gulf of America” or else lose federal funding.
The FBI reportedly has been questioning Environmental Protection Agency employees about $20 billion in climate and clean energy grants approved under the Biden administration, which EPA Administrator Lee Zeldin has insisted were issued hastily and without oversight. According toThe Washington Post, the Justice Department has asked several U.S. attorneys to submit warrant requests or launch grand jury investigations, but those efforts have been rejected due to lack of evidence or “reasonable belief that a crime occurred.” “It’s certainly unusual for any case to involve two different U.S. attorney offices declining a case for lack of probable cause and to have the Department of Justice continue to shop it,” Stefan D. Cassella, a former federal prosecutor, told the Post. Several nonprofits said their Citibank accounts holding the funding have been frozen without explanation.
Some Democratic states are apparently freezing out Tesla in response to Elon Musk’s political maneuvers within the Trump administration. Tesla operates on a direct-to-consumer sales model, so it doesn’t have to go through dealerships. More than 25 states ban or restrict direct EV sales in some way. The company has been lobbying to get permission to sell directly in these states, but some Democratic lawmakers are “disgusted” by Musk’s moves in Washington and are rebuffing lobbyists or dropping their support for proposed legislation allowing direct sales.
Apple is in trouble for claiming some of its Apple Watches are “carbon neutral.” A group of customers are suing the company after learning its claims relied on carbon offsetting projects in protected national parks or heavily forested areas, instead of “genuine” carbon reductions. “The carbon reductions would have occurred regardless of Apple’s involvement or the projects’ existence,” the plaintiffs said in their complaint. “Because Apple’s carbon neutrality claims are predicated on the efficacy and legitimacy of these projects, Apple’s carbon neutrality claims are false and misleading.” The lawsuit seeks damages, as well as an injunction that prevents Apple from using the carbon neutral claim to market its watches. Apple has a goal of net-zero carbon emissions by 2030.
Researchers in Amsterdam have examined the nests of birds known as common coots and discovered plastic items dating back to the 1990s, including a McDonald’s McChicken wrapper from 1996, and a Mars wrapper promoting the 1994 USA FIFA World Cup. “History is not only written by humans,” said Auke-Florian Hiemstra, who led the research. “Nature, too, is keeping score.”

Did a battery plant disaster in California spark a PR crisis on the East Coast?
Battery fire fears are fomenting a storage backlash in New York City – and it risks turning into fresh PR hell for the industry.
Aggrieved neighbors, anti-BESS activists, and Republican politicians are galvanizing more opposition to battery storage in pockets of the five boroughs where development is actually happening, capturing rapt attention from other residents as well as members of the media. In Staten Island, a petition against a NineDot Energy battery project has received more than 1,300 signatures in a little over two months. Two weeks ago, advocates – backed by representatives of local politicians including Rep. Nicole Mallitokis – swarmed a public meeting on the project, getting a local community board to vote unanimously against the project.
According to Heatmap Pro’s proprietary modeling of local opinion around battery storage, there are likely twice as many strong opponents than strong supporters in the area:

Yesterday, leaders in the Queens community of Hempstead enacted a year-long ban on BESS for at least a year after GOP Rep. Anthony D’Esposito, other local politicians, and a slew of aggrieved residents testified in favor of a moratorium. The day before, officials in the Long Island town of Southampton said at a public meeting they were ready to extend their battery storage ban until they enshrined a more restrictive development code – even as many energy companies testified against doing so, including NineDot and storage developer Key Capture Energy. Yonkers also recently extended its own battery moratorium.
This flurry of activity follows the Moss Landing battery plant fire in California, a rather exceptional event caused by tech that was extremely old and a battery chemistry that is no longer popular in the sector. But opponents of battery storage don’t care – they’re telling their friends to stop the community from becoming the next Moss Landing. The longer this goes on without a fulsome, strident response from the industry, the more communities may rally against them. Making matters even worse, as I explained in The Fight earlier this year, we’re seeing battery fire concerns impact solar projects too.
“This is a huge problem for solar. If [fires] start regularly happening, communities are going to say hey, you can’t put that there,” Derek Chase, CEO of battery fire smoke detection tech company OnSight Technologies, told me at Intersolar this week. “It’s going to be really detrimental.”
I’ve long worried New York City in particular may be a powder keg for the battery storage sector given its omnipresence as a popular media environment. If it happens in New York, the rest of the world learns about it.
I feel like the power of the New York media environment is not lost on Staten Island borough president Vito Fossella, a de facto leader of the anti-BESS movement in the boroughs. Last fall I interviewed Fossella, whose rhetorical strategy often leans on painting Staten Island as an overburdened community. (At least 13 battery storage projects have been in the works in Staten Island according to recent reporting. Fossella claims that is far more than any amount proposed elsewhere in the city.) He often points to battery blazes that happen elsewhere in the country, as well as fears about lithium-ion scooters that have caught fire. His goal is to enact very large setback distance requirements for battery storage, at a minimum.
“You can still put them throughout the city but you can’t put them next to people’s homes – what happens if one of these goes on fire next to a gas station,” he told me at the time, chalking the wider city government’s reluctance to capitulate on batteries to a “political problem.”
Well, I’m going to hold my breath for the real political problem in waiting – the inevitable backlash that happens when Mallitokis, D’Esposito, and others take this fight to Congress and the national stage. I bet that’s probably why American Clean Power just sent me a notice for a press briefing on battery safety next week …
And more of the week’s top conflicts around renewable energy.
1. Queen Anne’s County, Maryland – They really don’t want you to sign a solar lease out in the rural parts of this otherwise very pro-renewables state.
2. Logan County, Ohio – Staff for the Ohio Power Siting Board have recommended it reject Open Road Renewables’ Grange Solar agrivoltaics project.
3. Bandera County, Texas – On a slightly brighter note for solar, it appears that Pine Gate Renewables’ Rio Lago solar project might just be safe from county restrictions.
Here’s what else we’re watching…
In Illinois, Armoracia Solar is struggling to get necessary permits from Madison County.
In Kentucky, the mayor of Lexington is getting into a public spat with East Kentucky Power Cooperative over solar.
In Michigan, Livingston County is now backing the legal challenge to Michigan’s state permitting primacy law.
