The United Nations calls 24/7 carbon-free energy generation, also known as hourly matching, “the end state of a fully decarbonized electricity system.” It means that every kilowatt-hour of electricity consumed is matched with a zero-emissions electricity source, every hour of every day. It’s something that Google and Microsoft are aiming to implement by 2030, and it represents a much more significant climate commitment than today’s default system of annualized matching
So here’s a positive sign: LevelTen Energy, the leading marketplace for power purchase agreements, just raised $65 million in Series D funding, led by the investment firm B Capital with participation from Microsoft, Google, and Prelude Ventures, among others.
The money will help support LevelTen’s work with the Granular Certificate Trading Alliance, a collaboration it started last December in partnership with the Intercontinental Exchange, a data firm that operates global financial marketplaces. Together they’re building a platform for trading and managing “granular certificates,” hourly-matched energy certificates that will help corporations — and ideally the electricity sector at large — move to 24/7 hourly matching. Other partners to the alliance include Google, Microsoft, and the energy companies AES and Constellation.
To date, LevelTen has facilitated over $15.8 billion in power purchase agreements, asset sales, and other clean energy transactions, totaling over 7 gigawatts of clean energy. Overall, the company has raised more than $125 million, with past investors including the My Climate Journey Collective as well as the investment arms of oil and gas companies such as Equinor and TotalEnergies, which are adding renewables to their portfolios.
Bryce Smith, LevelTen’s founder and CEO, told me the platform will launch its first auctions for hourly-matched clean energy by the end of the year, with initial customers expected to be corporate partners like Google and Microsoft themselves.
“Corporates have been leading the way in a lot of respects and they're doing it again on the granular certificate front,” Smith said. He sees it as LevelTen’s job to get more industry players onboard by creating the transaction infrastructure to enable hourly matching. “So there's a bit of a ‘build it and they will come’ aspect to this,” he told me.
Realistically, though, it’s unlikely that the electricity industry will move towards 24/7 clean energy absent some serious incentives to do so. That’s why the Biden administration’s proposed hydrogen tax credit rules could be so powerful. They stipulate that to qualify for the largest IRA subsidies, clean hydrogen must be produced using a relatively new source of carbon-free electricity, generated within the same hour that it’s used and in roughly the same location. If these regulations aren’t deleted or seriously altered by this or another new administration (which they probably will be), power grids would have until 2028 to set up new systems for hourly accounting, thereby laying the groundwork for 24/7 matching across the electricity sector at large.
That potential, tenuous and unlikely though it may be, has LevelTen excited, and the company is leaning hard into hydrogen. LevelTen is a founding member of the Hydrogen Demand Initiative, a coalition formed by the Department of Energy to ensure that the clean hydrogen produced by the seven designated hydrogen hubs is actually sold. The DOE is allocating $1 billion to help catalyze demand, and it’s up to H2DI to figure out how to distribute that. “A component of that is figuring out how to bring buyers and sellers together easily and smoothly,” Smith told me. “And that's the role that we play in creating a marketplace where buyers and sellers can find each other and execute.”
Smith is aware that a change in administration could very well mean a change in the hydrogen tax credit rules, potentially decreasing incentives for green hydrogen and making hydrogen produced from natural gas with carbon capture and storage (“blue hydrogen”) or hydrogen produced without CCS (“gray hydrogen”) more attractive. He said the LevelTen platform would likely support transactions that involve a “variety of hydrogen colors and technologies.”
“What's most important for us always is figuring out how to put a vital technology on the fastest track to scaling,” Smith told me. “And if that means accommodating different colors for some period of time, we have the end goal [of green hydrogen] always in mind.”
As LevelTen scales, it’s also working to get more utilities onto its platform. Smith told me that utility customers have, “really only fairly recently realized that their procurement needs around renewables are massive.” As the push to “electrify everything” gains momentum and data centers suck up more and more power, utilities are increasingly investing in renewable energy to meet their electricity needs, diversify their portfolios and respond to customer demand for clean power. “We're used to seeing really slow, fairly predictable demand and electricity growth from a utility perspective, and that's changing pretty dramatically,” Smith told me.
LevelTen currently operates in 29 countries across North America and Europe, and hopes to use its recent funding to expand into new regions.

The additional clean capacity would represent nearly 3% of North America’s existing total.
North America has about 37.5 gigawatts of total virtual power plant capacity, according to energy consultancy Wood Mackenzie’s latest estimate, published last year. That capacity is spread across roughly 2,000 VPPs, which aggregate distributed energy resources like batteries, smart thermostats, and heat pumps to cut, shift, or supply electricity when the grid is under strain — effectively turning them into a single, coordinated power plant.
On Thursday, Google and VPP operator Voltus announced plans to add another 1 gigawatt of clean capacity over the next three or four years — or nearly 3% of North America’s existing total. Under Voltus’ “bring your own capacity” model, Google will fund the VPP to help meet its booming data center power needs, while Voltus will enroll businesses and households across the PJM Interconnection, the notoriously overstrained grid region spanning parts of the Midwest and Mid-Atlantic, compensating them for their participation either directly or through electricity bill credits.
The announcement expands on a three-year, 100-megawatt deal the two companies signed in June, extending their commitment through 2040. Voltus CEO Dana Guernsey told me that the smaller deal gave the companies a starting point for a much more ambitious partnership. “It’s a lot easier to explain to people how you’re going to 10x if you’ve already 1x, and so we had to start somewhere,” she said. “We always had our eyes set on bigger things.”
Earlier this month, Voltus closed an oversubscribed $225 million Series D round led by Generation Investment Management to scale its VPP portfolio to 20 gigawatts by 2030. The first phase of the Google partnership is also oversubscribed, Guernsey told me. While that flexible power won’t come online until next year, this means Voltus has already lined up over 100 megawatts of accredited capacity that PJM can count on to deliver when needed, much as it would a natural gas plant or solar-plus-storage installation.
In the meantime, the VPP operator says its broader PJM portfolio has already demonstrated what it can do. Last week, an unseasonably warm stretch of fall weather required PJM to activate its Emergency Load Response Program twice. With 46 gigawatts of generation offline for planned maintenance or construction and another 15 gigawatts unexpectedly unavailable, “distributed resources came through,” Guernsey posted on LinkedIn. “This is how a modern grid should work.” Based on preliminary data, she told me that Voltus delivered about 105% of its committed load reduction during the events.
And VPPs can do more than help avert emergencies. Grid operators are increasingly calling on distributed resources for routine grid management too, such as to ease daily price spikes, reduce emissions when the sun or wind isn’t available, or relieve congestion on a local line. “It’s nearly constant. I think soon we’ll be able to say it’s like every hour,” Guernsey told me.
So far this year, Voltus has reduced electricity demand in PJM by more than 200 gigawatt-hours. Now the company plans to lean more heavily on batteries, particularly at commercial and industrial sites, to accelerate its growth. Guernsey told me that with battery costs falling, electricity prices rising, and fixed payments to participants through 2040, the math now works to deploy batteries at scale, without exposure to unpredictable wholesale electricity prices.
She’s betting that other hyperscalers will see the value in large-scale battery deployments too. Most of the buzz today has revolved around hyperscalers bringing their own generation online — both to secure power faster and head off community opposition by paying their own way. Thus far, Google is the only hyperscaler committed to bringing its own distributed capacity through a VPP. But getting the big players to embrace these new “bring your own capacity” contracts, which Voltus launched last September, is central to its growth strategy.
Guernsey has likened these novel capacity contracts to the corporate renewable power purchase agreements that Google also helped pioneer in the early 2010s. Now she sees a similar opportunity for VPPs to move from a promising concept to a mainstream procurement tool.
“There’s been this notion that we’re coming up on an inflection point for a very long time,” she said of the VPP market. “And I want to be able to say we came up on the inflection point, we went past it, and now we are scaling. And this is an awesome proof point.”
The Federal Reserve raised the federal funds rate by a quarter point, the central bank announced Wednesday afternoon, its first rate change since Chairman Kevin Warsh took his seat in May and its first rate hike in over three years.
The federal funds rate will now sit between 3.75% and 4%. According to projections by regional Federal Reserve presidents and members of the Board of Governors, the central bank expects to hike rates one more time this year.
In its now characteristically brief statements, the Federal Open Market Committee said that the hike “will support a timelier return to the Committee's 2 percent goal” for inflation. Inflation is currently running at 3.4% and has been above the Fed’s 2% target since 2021.
The FOMC’s (brief) statement explaining the hike pointed to “resilient” domestic spending and “robust” capital investment. It characterized the economy as “expanding at a solid pace,” albeit with “elevated” uncertainty due to “geopolitical developments.”
This combination of factors — high oil prices due to the partial shutdown of the Strait of Hormuz and high investment in data centers — have helped push up yields on Treasury bonds, which helped maneuver the Federal Reserve into its rate hike. These rising Treasury yields have made raising capital more difficult for sectors besides artificial intelligence, very much including the capital-intensive renewable and clean energy industries.
Warsh attributed higher Treasury yields to “economic strength, competition for capital, and geopolitics,” in his press conference following the rate announcement. The yield on the 10-year treasury bond, often used as a benchmark for the cost of money throughout the economy, rose to over 5% on the news, the highest level since 2007.
The August Electricity Price Hub data is in.
It’s another hot and expensive summer.
Across the country, average household electricity bills are up 2.7% in the first eight months of the year, according to the latest update to Heatmap and MIT’s Electricity Price Hub, tacking on $4 per month to the typical bill. This level of rise is consistent with the pace set in 2024 and 2025, but faster than 2021 and 2023.
As we’ve discussed before, some of the fastest growth in prices comes either in the Atlantic Seaboard — with Washington, D.C., Virginia, and New Jersey all having year over year growth rates of at least 7.5% — thanks largely to increased demand and capacity payments in the PJM Interconnection marketplace. Another standout so far this year is Hawaii, which is uniquely dependent on imported oil to power its grid and has seen its 12-month trailing average prices rise by over 8% so far this year.
California, which is well known for seeing especially sharp price increases in recent years largely due to wildfire-related costs, has seen somewhat restrained bill growth so far this year across the state, with the 12-month-rolling average bill rising just 3% in the past 12 months and prices going up 4%. (That price level is still quite high, however, at almost 32 cents per kilowatt-hour, compared to a national average of around 19.)
Rates charged by Southern California Edison, one of the state’s big three investor-owned utilities, are up almost 15% in the past year, averaged across its baseline regions. The MIT researchers attribute this increase to two major factors: one, a decrease in the California Climate Credit, which is paid out to electricity customers from the state’s emissions cap-and-invest program. This year, the credit for Southern California Edison ratepayers is $72, applied to bills in July and August in tranches of $36. Last year, by contrast, Southern California Edison handed out $112 in two tranches, April and October.
The second factor in Southern California Edison’s inflated bills is an increase in the fixed charge portion of the bills ratepayers receive. Following changes in California state law designed to distribute the cost of the grid more equitably, SCE revamped its rate structure at the end of last year to include a “Base Services Charge” of $24 per month for customers not enrolled in any special rate program. At the same time, SCE instituted a roughly 10% decrease in its per-kilowatt-hour electricity rate in order to protect lower-income ratepayers (who would pay a fixed charge substantially lower than the baseline $24). PG&E moved to a similar system earlier this year.
When it introduced the new rates in November of last year, SCE said that “medium energy users” would likely see little change in their bills. Price Hub data suggests, however, that the typical household has seen a bill increase from the new service charge of 13%, even before accounting for the smaller climate credit.
