Banding Together: How Aggregation Helps Cities Buy Renewables at Scale
By Yuning Liu & Mia Reback
In March 2021, 24 local governments in Maryland joined together on a plan to purchase enough renewable energy to power more than 246,000 homes a year. They did this by issuing a joint request for proposal (RFP) through the Baltimore Regional Cooperative Purchasing Committee (BRCPC) to seek a supply of up to 240,000 MWh of renewable energy starting in 2022. This large-scale transaction was made possible by an energy procurement approach known as energy aggregation, which is a way for two or more buyers to purchase electricity from a utility-scale generation facility.
According to the new Intergovernmental Panel on Climate Change (IPCC) report, greenhouse gas emissions (GHGs) must peak within four years to limit global warming to 1.5°C, and cities have a critical role to play in meeting that target. Aggregation can be a powerful way for cities to rapidly increase their renewable energy and help decarbonize local economies at the necessary speed and scale. Yet most cities have not pursued aggregation due to an inadequate understanding of its novel deal structure and a lack of tools and resources to help streamline the process.
Aggregation can be a powerful way for cities to rapidly increase their renewable energy and help decarbonize local economies at the necessary speed and scale.
To help cities overcome these barriers, last year the American Cities Climate Challenge Renewables Accelerator, an initiative co-led by RMI and World Resources Institute, began organizing a Large-Scale Renewables Aggregation Cohort. This cohort provided technical assistance to more than 30 organizations, including the BRCP. A second iteration of the cohort is now underway with a new group of organizations. In addition, a newly released RMI report, Procuring Large-Scale Renewables through Aggregation: A Guide for Local Governments aims to help more cities understand and pursue aggregation.
As more and more cities take actions to decarbonize the electricity system, aggregation will be an increasingly important option that can provide buyers with several advantages, such as opening doors for smaller cities, creating positive network effects, and unlocking more cost savings.
Enabling Smaller Buyers to Access Large-Scale Projects
Aggregation can enable participation from smaller cities that, on their own, are not able to purchase enough electricity to warrant the attention from developers. This is particularly important for smaller communities with 100 percent renewable energy goals, as most municipalities cannot supply 100 percent of their electricity needs with on-site solar generation alone. Therefore, a utility-scale, off-site procurement will be an essential component of many smaller buyers’ decarbonization strategy.
One instance of a small buyer accessing large-scale renewables projects is a 25 MW joint solar purchase completed by MIT, Boston Medical Center (BMC), and Post Office Square (POS) in 2016. In this aggregated deal, MIT committed to buy 73 percent of the power generated by the new array, with BMC purchasing 26 percent and POS purchasing the remainder.
“Entering into a renewable power purchase agreement was our next step, but our consumption is too small to do it alone,” said Pamela Messenger, general manager of Friends of POS. “It is exciting to join forces with two industry leaders, allowing us to mitigate 100 percent of our electricity footprint.”
Similarly, other smaller local governments have also used aggregation to gain access, such as five local governments in Maine. They teamed up for the state’s first multi-town renewables project, a 4 MW solar array, which provides climate benefits equivalent to more than 4,000 acres of forests.
Without pooling the electricity demand with other buyers, smaller cities would not be able to access utility-scale projects on their own, making it difficult to reduce their carbon emissions efficiently.
Creating Knowledge-Sharing Opportunities
By joining together, cities can not only aggregate their buying power but also pool their knowledge to streamline procurement processes. The shared experience among participants can generate positive network effects, including increased mentorship, increased credibility, and support for inexperienced buyers.
For example, the City of Nashville partnered with Vanderbilt University last year to purchase electricity from a 125 MW solar project as part of the Tennessee Valley Authority’s Green Invest program. This public-private partnership allowed the city to leverage the expertise of the University’s Large-Scale Renewable Energy Study Advisory Committee to identify the best risk mitigation strategy.
According to Susan R. Wente, interim chancellor of Vanderbilt University, “We want this partnership to serve as a model of collaboration that other organizations within our region and beyond can replicate to make long-term, lasting changes to protect our shared environment.” In fact, the connections formed within the aggregation group have garnered national media attention and are sending a powerful signal to utilities, policymakers, and developers that local governments are serious about rapidly decarbonizing the electricity system.
In addition, a group of buyers can also share external lawyers, accountants, or consultants. For instance, 15 Pennsylvania municipalities and public entities, which also participated in the Renewables Accelerator’s Large-Scale Renewables Aggregation Cohort, have teamed up to investigate the viability of investing in a joint solar deal. The 15 entities issued a joint RFP for energy consultants in May 2021 to share external advisory services.
Unlocking More Cost Savings
Throughout the collaborative process, aggregated deals can produce various cost savings because they enable cities to achieve greater economies of scale by combining the renewable energy demands of multiple buyers.
For example, a National Renewable Energy Laboratory analysis estimates that procuring 100 MW of solar instead of 5 MW can reduce development costs by 24 percent. This can lead to cost savings in the form of lower power purchase agreement prices for all buyers, regardless of size.
In another case, the company Enel X, which is working with the BRCPC on a joint purchasing strategy, found that renewable energy projects typically must be over 20 MW in size to be economical. The company discovered that aggregation is one way for smaller buyers to participate in large projects.
In Florida, 12 cities joined together to form the Florida Municipal Solar Project. They are developing 372.5 MW of zero-emissions energy capacity, enough to power 75,000 Florida homes. According to Jacob Williams, CEO and general manager of the Florida Municipal Power Agency, “By working together, our cities are able to provide clean power to their communities in a cost-effective way.” Clint Bullock, Orlando Utilities Commission general manager and CEO, explained, “We can leverage the economies of scale to bring the price of solar down to a point where a dozen municipal utilities can afford to sign on and I believe this is something people around the country will take notice of.”
Better Together
As more cities set goals to transition to renewables, aggregation is democratizing clean energy access by enabling participants, especially smaller buyers, to collectively develop significantly larger renewables projects than any one buyer would be able to access individually. The partnerships can create positive network effects through knowledge sharing and inspire other organizations within the region to replicate the collaboration model. By unlocking more cost savings, aggregated deals provide a lower-cost mechanism for cities to achieve climate goals efficiently.
The new IPCC report underscores the urgency of decarbonizing the electricity system and reducing GHGs. To play their part, cities need to increase the pace and scale of renewable energy procurement. Although aggregation is still a relatively underutilized procurement method, this approach is crucial to help them do that.
Procuring Large-Scale Renewables through Aggregation: A Guide for Local Governments helps walk local governments through the aggregated procurement process step-by-step and links to other key tools and resources relevant to each stage.
Cities must act now to curb greenhouse gas emissions. The best path forward involves engaging all actors and ensuring a more promising economic structure for a wide array of purchasers. In the battle against climate change, it is better to aggregate than to go it alone.

Aptera has publicly unveiled the production-intent version of its long-awaited solar EV, which it says will start deliveries by the end of this year.
Update: We swung by the booth a took a few pictures of Aptera’s production-intent vehicle chassis, see below.
Aptera has a long history in the automotive space, dating all the way back to its original founding in 2006 by co-founders Steve Fambro and Chris Anthony. It has had the same basic teardrop design all along, but at the time it was going to be fueled by a small gas engine, promising 330 miles per gallon.
But the last iteration of Aptera hit many bumps in the road, and went defunct in 2011, having to return thousands of customer deposits.
Then, in 2019, the company was relaunched, by the same original founders as before. But this time, it had a solar-powered electric car – which, frankly, makes a lot more sense for a futuristic vehicle than a gas engine does.
That’s the iteration we’re on now, and six years later – and nearly 20 years after the company’s first founding – Aptera says it’s finally ready to produce its solar EV.
It’s showing off its production-intent chassis at the Consumer Electronics Show this week, offering the public a chance to see this vehicle which it says will go into production and delivery this year. Its booth is in the central plaza, outdoors in the sun – where a solar EV belongs.
The company has been showing off its progress towards production intent over the course of the last years, doing wind tunnel testing of what it claims will be one of the lowest-drag vehicles ever (with a previously-claimed .13 Cd), receiving carbon bodies in August and completing its first low-speed drive in October.
Now the car is out and about driving normally at CES (and Aptera is offering media ride-alongs, which we’ll hopefully get a chance to fit in). Aptera says that it drove the car for around 20 miles yesterday, and it ended the day with more charge than it started due to its extensive solar panels, which Aptera is showing off in production-intent form for the first time.
The panels cover the vehicle’s hood, dash, roof and hatch and Aptera says they can generate up to 40 miles of free driving per days, powered by sunlight. In sunny climates, this will give owners over 10,000 miles per year of solar-powered driving.
On a sunny Las Vegas winter day, as it was for the reveal, the solar panels should be working quite nicely (though they would work even better if it weren’t one of the shortest days of the year).
The unveil included a short livestream at Aptera’s outdoor booth in the Central Plaza, which you can watch below:
The livestream included a short speech by co-CEO Chris Anthony and a quick vehicle walkaround, including showing off the vehicle’s NACS port, which Aptera was the first to announce adoption of way back in 2022.
Aptera says it has another announcement coming soon regarding the vehicle’s battery pack, and that its anticipating offering track time in the car in a few months for investors (the company is funding itself through a crowdfunding campaign through which it has raised $135 million of equity).
Previously, Aptera said the vehicle would have multiple battery options, with 250, 400, and even 1,000-mile (!) battery packs (which this author thinks is unrealistically excessive, and frankly a sign for pause). But Aptera has backed off from talking much about its previous 1,000-mile target, and all we heard about during this reveal is the 400-mile, 45kWh pack that will be included on the company’s $40,000 launch edition vehicle (which will have limited options otherwise).
Aptera says that it anticipates first deliveries of its launch edition by the end of this year – a timeline which the company has stated before, but which we wouldn’t be surprised to see slip. Nevertheless, that’s the messaging.
Aptera says it has 50,000 reservations for its vehicle, at $100 a pop (or $70, if you use our Aptera referral link). You can reserve an Aptera over at Aptera’s website.
But if you have an EV that *isn’t* covered with solar panels, maybe you can install solar panels on your home’s roof and charge your vehicle through solar anyway.

Who said minivans weren’t cool? Hyundai’s first electric minivan (which could double as a camper van) was spotted in public without camouflage, giving us a better look at what to expect. Check out the upcoming EV below.
When will Hyundai’s first electric minivan launch?
Hyundai is preparing to launch its first all-electric minivan this year. The Staria is the electric successor to the Starex, Hyundai’s multi-purpose vehicle (MPV) introduced in 2021.
Last March, Hyundai revealed its new ST1 electric business van platform, based on the Staria powertrain. The ST1 is Hyundai’s first commercial EV with configurations including a refrigerated van and chassis cab. Meanwhile, the minivan will get its own model in 2025.
According to Korea’s Newsis, Hyundai will convert one of its production lines at its Ulsan Plant 4 on January 25, 2025, for the Staria electric.
Ahead of its official debut, we are already getting a look at Hyundai’s first electric minivan undisguised. The Staria EV was spotted by the online community “Family Staria” in a Korean parking lot without camouflage.
You can see that the EV model has a design similar to that of Hyundai’s Staria Lounge, which transforms from a seven- or nine-seat limousine into a full-fledged camper van.
Outside of the grille, which is now closed and includes a charging port, the electric minivan is a near replica of the premium Staria Lounge.
Given it’s still a test vehicle, the design could change once finalized. A tag on the windshield reads “Vehicle for UT Evaluation of the Road Vulnerable,” suggesting it has a few more tests before being released to the general public.
The Staria electric is expected to feature Hyundai’s latest 84 kWh batteries. Local reports suggest it will be able to handle over 10% more capacity than the ST1.
Hyundai’s first electric van is expected to launch in overseas markets. According to The Korean Economic Daily, Hyundai plans to start production of the Staria EV in Europe in the first half of 2026. European-made models will be sold locally and overseas, such as in Australia and Thailand.
Will Hyundai launch a camper van version like the Staria Lounge? More info will likely be released soon with an official launch expected this year. Stay tuned for updates.

Elon Musk claims Tesla is doing ‘unsupervised self-driving trials’ while playing video games
Elon Musk is claiming that Tesla has started doing ‘unsupervised self-driving trials internally’. He made the claim while playing video games, and It should be taken with a grain, or pound, of salt.
Yesterday afternoon, on a Tuesday, Elon Musk, CEO of Tesla and defacto in charge of 6 companies and a government department, was playing video games and streaming on X for more than an hour.
During the stream, fans were asking him questions and one of them was about Tesla’s self-driving effort.
Musk said:
Tesla Full Self-Driving unsupervised, maybe I’ll mention, we are going to [correct himself], we actually are doing trials of that with Tesla employees already and we expect to have that in commercial service sometime this year, which I mentioned at the last earnings call.
There are two things that Musk said at the last earnings call. He did indeed claim that Tesla would launch its “unsupervised Full Self-Driving” capability in California and Texas around Q2 2025.
He also said that Tesla started testing its robotaxi ride-hailing app with employees in the Bay Area:
We have for Tesla employees in the Bay Area. We already are offering ride-hailing capabilities. So, you can actually — with the development app, you can request a ride, and it will take you anywhere in the Bay Area.
However, he also said that Tesla had “safety drivers” behind the wheel for this test program, which means that it is no more than its current “Supervised Full Self-Driving,” a level 2 driver assist system. It is mainly to test the ridesharing features of the app rather than a different version of its self-driving system.
That makes sense, considering that Tesla would need a permit to operate a self-driving vehicle in California, even as part of a test program, and we haven’t found Tesla’s permit application yet
With this new comment, Musk clearly said “unsupervised” self-driving.
Electrek’s Take
I wouldn’t be shocked if Elon misspoke here while playing video games or he is plain confused about the situation.
Considering Tesla doesn’t have any permit to operate driverless vehicles, if it is operating a “unsupervised self-driving trials internally”, it has to be doing it on private property, which could be no more than the Cybercabs we have seen driving around Gigafactory Texas.
It’s not much different than Tesla’s ‘We, Robot’ event, which was purposely located at Warner Bros’ studio lot, which are private roads.
I seriously doubt that Tesla is currently operating unsupervised self-driving vehicles on public roads.
