Burlington business owners have banded together to plead with Gov. Phil Scott for help with the public safety issues that are plaguing the city’s downtown.
Mayor Emma Mulvaney-Stanak and the Burlington City Council have also asked the governor to pour more state resources and effort into solving these problems — requests that Scott has shrugged off.
But the letter from the Church Street Market Commission puts an economic spin on things, saying that Chittenden County contributes a quarter of the state’s total tax income and noting that the Queen City is “the top spot for tourism” in Vermont. “A crisis in Burlington is a crisis” for the the state, commissioners wrote.
“As you are well aware, Burlington’s downtown is essentially in a state of emergency,” reads the letter, which was sent on Wednesday. “Our residents, business owners, their employees and property owners, have let us know, loudly and clearly, that time has run out.” buff.ly/kwrl7Oy

A historic moment for American energy: 140,000+ home batteries | 580 megawatts
As California baked under extreme heat and energy demand surged on September 9, Sunrun and @teslaenergy dispatched more than 140,000 home batteries, delivering 580 MW of peak power to the state's grid in the largest residential distributed power plant event ever recorded in the United States.
The dispatch event provided enough capacity to power every household in Sacramento County during peak hours. The extra power helped increase the grid's operating margin and put downward pressure on real-time energy prices for everyone in the state.
Through grid service programs like DSGS and ELRP, home storage and solar are doing more than providing backup power and energy security to families. They’re helping make the grid more affordable and reliable while reducing the need for costly new poles, wires, and peaker plants.
Everyday homeowners are keeping California's grid stable and making history in the process, all while being compensated for it. That’s the energy future we’re building in America.

Next week, Sunrun CEO Mary Powell joins Diane Brady, Editorial Director at Fortune, to discuss why the future of AI infrastructure may be less about building more and more about unlocking the capacity right in front of us.
The AI revolution is creating an unprecedented demand for electricity, with much of the conversation focusing on new power plants. However, we believe the biggest opportunity may already exist in neighborhoods across America.

California’s heat is pushing electricity demand and energy prices higher. Tonight, home batteries are stepping up. More than 90,000 Sunrun batteries will be dispatching flexible capacity across the state to support grid reliability, reduce the risk of rotating power outages, and put downward pressure on energy costs for everyone.

AI is driving unprecedented demand for compute and electricity. Meeting that demand has traditionally meant building more centralized data centers and grid infrastructure, a process that can take several years.
We're introducing a different approach.
Today, Sunrun launched a distributed AI compute pilot that places compute nodes in homes already equipped with solar and battery storage. By bringing compute closer to where reliable, affordable energy is generated and end users are, we're exploring a model that could bring a significant amount of compute capacity online in a fraction of the time it would take to build new energy infrastructure.
Just as distributed energy transformed households from energy consumers into energy producers, distributed compute has the potential to give everyday Americans a direct role in powering the nation's AI future and sharing in the economic value it creates.

“Customers are in the driver's seat when they have our systems in their home. This is just another example of the innovation that we can drive around serving a critical societal need like AI. The reality is we depend on it. We all depend on it every day. And now this is a way for individual homes to become part of this demand, by supplying energy and getting paid for it.”
Mary Powell joined Brian Sullivan on CNBC Power Lunch to discuss Sunrun's new distributed compute pilot and how homes with solar and battery storage can host compute capacity while creating value for families.

Sunrun CEO Mary Powell joined Cheryl Casone on Fox Business to discuss our announcement with Renew Home and Tesla to create America's largest distributed power plant — a 16.8 GW network of home batteries and smart devices that can immediately help meet the country's rapidly growing energy demand.
"There really is not a lot to meet the moment right now. So what is wonderful about this partnership is that we can altogether meet this moment and bring these electrons on to the grid to help particularly with data centers. It helps massively with speed to interconnection because utility solutions are still three years away, five years away, 10 years away."
Powell went on to emphasize that one of the solution's most compelling aspects is that it benefits customers at a time when electricity rates are climbing by delivering energy savings, compensation opportunities, and increased household resilience.
"That's why I'm so passionate about this. I also see it as we're providing Americans with what they want, which is independence, control, financial stability, and on top of that, they get to then make revenue off of these technologies."

So the Knicks won their first championship in 53 years and I was there in San Antonio to see it.
But first I lost my mind.
Wrote about how much of a wreck I’ve been during this magical playoff run and how even this title might not cure it

Mike Brown:
"The buy in. It was a contract that I had everybody sign opening dinner night and I still have it framed. Everybody's signature from Mr. Dolan to Leon Rose, all the coaches, all the players, all the staff that was there that night signed and basically it was about committing to sacrifice, having a competitive spirit, being connected, believing in each other in the process while holding everybody accountable even myself...I told everybody that night if you're not gonna abide by this I'd have more respect for you to not sign it than to sign it and BS your way through tonight and BS your way through this and everybody bought in from day 1"

AI data centers are driving up energy demand, and everyday Americans are right to wonder what that means for their bills.
In this NBC report, Brian Cheung sits down with Sunrun customer Jeff Wright and President Paul Dickson to explain how home batteries paired with solar aren't just for backup power — they're forming distributed power plants that can supply critical energy to data centers while keeping costs down for American families.
The AI buildout should work for everyone. This is how.

critical part of the path to energy affordability
A new report shows that Sunrun’s first-of-its-kind distributed power plant with PG&E successfully supplied targeted power to neighborhoods with highly-constrained electric grids
When power lines and substations are nearing capacity, utilities have to add more distribution infrastructure. This collaboration shows that home batteries can come to the rescue by dispatching critical energy exactly when and where it’s needed.
More than 1,000 Sunrun customers’ storage-plus-solar systems exported energy over last summer and fall to alleviate overloaded substations and power lines, with the goal of helping PG&E avoid or defer distribution upgrades while generating net savings for all utility customers.
“Working with partners like Sunrun is a win for our customers, our electric grid and California as a whole. This program shows how customers can help improve local grid reliability as we support the state’s growing need for energy,” said Patti Poppe, CEO of PG&E Corporation.

Always a pleasure to chat with @LizClaman about the importance of energy. Grateful that during storms and energy capacity challenges we can be there for the customers we serve, and supply energy back to the grid when needed.
Winter Storm Fern left hundreds of thousands of homes without power after impacting many parts of the country with ice and freezing temperatures, causing energy generation and distribution to go offline.
CEO Mary Powell joined @LizClaman to discuss how Sunrun’s products and services are designed to meet moments like these, providing homeowners with energy independence, reliability, and security, all while sending critical energy back to the grid.
“We are bringing independence to Americans [and] we are helping to build a grid that can be more energy independent,” Mary said. “There is nothing more reliable than the kind of distributed power plant that we’re building.”
