// tl;dr

New Jersey Governor Mikie Sherrill signed the Data Center Fair Share Act and two companion bills, tying a data center's place in the grid queue to funding ratepayer energy upgrades. The state says the package saves ratepayers over $1 billion a year, including a flat $25 credit for every residential customer. The law itself doesn't specify "heat pump" — it tells the Board of Public Utilities to design the program, so the mechanics are still being written.
Sunrun is piloting a "distributed data center": small AI compute nodes installed inside the houses of its existing solar-and-battery customers, who get paid to host the hardware. Sunrun hasn't disclosed the pay or named a compute buyer yet, but it has 1.1 million existing customers to draw from. Separately, Sunrun, Tesla, and Renew Home say linking home batteries and smart thermostats could add up to nearly 17 gigawatts of grid capacity.
Spotify rolled out an in-app AI chatbot called "Talk to Spotify," built into the home screen and now-playing view for Premium subscribers in the US, Ireland, and Sweden. You type or speak requests for playlists, artist trivia, or your own listening history; Spotify's own announcement compares it to "a Gemini/ChatGPT-esque chatbot." It's beta, Premium-only, and limited to three countries.
Hemispheric, co-founded by the engineer who helped build Apple's FaceID, came out of six years of stealth with $52 million in funding and an EEG model that flags PTSD, depression, traumatic brain injury, or Alzheimer's from a 15-minute session, no MRI required. It's shown data to the FDA but has no clearance or timeline yet.

We've been on the data-center-affordability fight since Governor Sherrill first floated a "bring your own power" mandate in late May, and today it became law: New Jersey is the sharpest version yet of states trying to make the AI boom pay its own way, rather than just capping it. Sunrun took a different route to the same problem today: instead of a state mandate, it's trying to turn a million existing rooftops into the data center itself, no fund required. Spotify's chatbot is a smaller-stakes version of the same pattern we keep tracking: AI moving from something you seek out to something that just appears on a screen you already use. And the week's most hopeful entry breaks from the pack — a serious, well-funded shot at catching brain disease years before symptoms show, from someone who's built this kind of infrastructure-scale AI before.

Today: New Jersey signed a law tying data-center grid priority to funded home energy upgrades, Sunrun started paying homeowners to host AI compute nodes, Spotify put a chatbot on its homepage, and an EEG model from Apple's FaceID engineer headed to the FDA for early brain-disease detection.

1. New Jersey signed the data-center fight into law: a spot in the grid queue, in exchange for funding your heat pump.

The mandate we flagged in May just became a specific, if unfinished, mechanism.

Back in late May, Governor Mikie Sherrill floated the idea that data centers should bring their own power rather than push the cost onto other ratepayers. On July 1, the legislature turned that into a bill; on July 7, she signed it into law as the Data Center Fair Share Act, alongside two companion bills that also rein in transmission-project oversight and utility return-on-equity. The state's own figures put the full package's savings at over $1 billion a year for ratepayers, including a flat $25 credit through the Residential Universal Bill Credit program for every residential customer, plus an additional $150 for low- and moderate-income households — arriving after a run of steep rate hikes that made energy affordability a defining issue in last year's governor's race. Trade coverage of the law's mechanism describes something sharper than a flat fee: a data center can fund a ratepayer's swap from an electric-resistance heater to a heat pump, or fund rooftop solar and a battery, and get priority interconnection to the grid in return. One honest catch: the law's text doesn't say "heat pump" anywhere. It directs the Board of Public Utilities to design the program, so the specific rules are still being written.

So far, New Jersey has the most specific answer to a question a lot of states are now asking. A flat moratorium, the tool a handful of towns and one state have already reached for, stops new construction outright. This law instead tries to make the boom's own money do useful things: pay down the specific costs (transmission upgrades, capacity-price spikes) that data centers are shown to cause, while funding the exact home upgrades — heat pumps, rooftop solar, batteries — that reduce a household's own exposure to volatile electricity and gas prices. Whether it works comes down to what the BPU actually writes into the tariff standards it's now required to design — the rulebook, not the signing, is the thing to watch.

Utility Dive July 8 2026 New Jersey Governor Mikie Sherrill signed the Data Center Fair Share Act and companion bills into law tying data center grid interconnection priority to ratepayer energy upgrade funding full package saves ratepayers over 1 billion dollars a year 25 dollar flat credit through Residential Universal Bill Credit program Board of Public Utilities to design tariff standards — utilitydive.com · July 8, 2026

Why this matters: If you live in New Jersey with an old baseboard or resistance heater, there is now a real, if unfinished, path to getting it replaced on someone else's dime. Action this week: Follow this one, because the BPU's rulebook is what decides whether the heat-pump mechanism is real money or just a press release — watch for the standards it publishes over the next few months. If your own state is fighting over data centers right now, this is the alternative to a flat moratorium: make the data-center boom pay for the fix instead of just stopping it.

2. Sunrun will pay you to let an AI data center live in your house.

No fund, no campus, just a compute node in your garage.

Sunrun, the home solar and battery company, is expanding a pilot it calls a "distributed data center": small compute nodes, about the size of a desktop tower, installed inside the homes of customers who already have its solar panels and batteries. Sunrun pays homeowners to host the hardware, though it hasn't disclosed how much, and it's in talks with enterprise compute buyers, homebuilders, and utilities without a named partner yet. What makes this more than a pitch deck is scale: Sunrun already has 1.1 million existing solar-and-battery customers it could tap if the pilot works. It isn't happening in isolation. Separately, Sunrun, Tesla, and Renew Home say linking home batteries and smart thermostats into a "virtual power plant" could add up to nearly 17 gigawatts of distributed grid capacity.

Put the two pieces together and the bet becomes clear: instead of building a new hyperscale campus and fighting a town over its water and power draw, treat a million existing rooftops as the data center. It's unproven at this scale, and the pay to homeowners is still undisclosed, which matters a great deal if you're the one hosting the box in your garage. It's also a different answer to the problem New Jersey just legislated. New Jersey passed a law forcing the trade. Sunrun is just negotiating it, deal by deal, with no Board of Public Utilities setting the price.

Why this matters: If you already have solar and battery storage, there may soon be real money on the table for hardware you're not using at capacity today. Action this week: Call your installer and ask whether a program like this is coming to your setup, and what it actually pays before you agree to anything. Follow this pilot over the next few months, because "proves out" is doing a lot of work in that sentence, and the pay rate is the detail that decides whether it's a good deal or a bad one.

3. Spotify put an AI chatbot on your home screen. You didn't have to go looking for it.

The AI didn't wait for you to seek it out this time.

Spotify started rolling out an AI chatbot called "Talk to Spotify" this week, built into the home screen and the now-playing view of the app, for Premium subscribers in the US, Ireland, and Sweden. You type or speak a request — "play some artists I haven't heard before," or, from Spotify's own announcement, "add some Bad Bunny, just his recent stuff" — and it builds playlists, follows artists, and answers questions about a song's backstory, pulling from your actual listening history. Spotify's own announcement described it, notably for a company describing its own product, as putting "a Gemini/ChatGPT-esque chatbot" inside its homepage. The rollout is limited: beta, three countries, English only, Premium subscribers only.

This is a chatbot appearing inside an app hundreds of millions of people already open every day. Nobody had to go looking for it. Amazon Music did something similar with Alexa Plus last year, and the same pattern keeps repeating: a chatbot showing up on the screen you were already looking at, in a shopping app or a work tool nobody asked to have "AI-powered" added to it.

Why this matters: You don't choose to try AI anymore in a growing number of apps; it just appears on a screen you were already looking at, whether or not you asked for it. Action this week: If you've got Spotify Premium, check your home screen this week and try one real, specific request instead of a vague one, so you actually see what it can and can't do before it changes again. If you've got a friend who lives inside that app, share this with them, because they're about to have an opinion on it whether they want one or not.

4. The engineer who helped build FaceID is now pointing AI at your brain, and the FDA is watching.

Back in June we flagged AI catching dementia early. This week it got a name and a founder.

Back in June, we flagged the beat: AI catching dementia years before symptoms show up, using non-invasive signals. This week it got a name, a founder, and $52 million behind it. Hemispheric came out of six years of stealth, co-founded by Gidi Littwin, the deep-learning engineer who helped build Apple's FaceID and hand-tracking for the Vision Pro, and Hagai Lalazar, who had already been building AI to study the brain without surgery. The company's model reads a roughly 15-minute EEG session — a headset and some simple tasks, no MRI, no dye, no surgery — trained on brain-recording data gathered from 100,000 people, and flags PTSD, depression, traumatic brain injury, or Alzheimer's. Littwin's stated goal is blunt: make a brain-health check as routine as a blood test. The honest caveat, because every one of these needs one: Hemispheric has shown architectural data to the FDA, but nothing is cleared yet, and there's no approval timeline.

This is a well-funded, technically serious effort at an early regulatory stage, not something your doctor can order today. Littwin's own account of building FaceID and Vision Pro's hand-tracking involved the same kind of massive, unglamorous data-collection operation now behind Hemispheric's brain model — "hundreds of thousands of subjects' worth of data," by his own description. He's pointing that same skill at a new problem: gathering enough real brain data to train a model on something that's mostly been stuck on small, underpowered studies. It also lands differently than the rest of this week's AI coverage: a story that ends with people getting help earlier, instead of a fight over who pays or who's watched.

Why this matters: If you or someone you love has been stuck waiting on a slow, uncertain diagnosis for PTSD, depression, traumatic brain injury, or Alzheimer's, there is now a specific, well-funded effort aimed at catching it years earlier with nothing more invasive than a headset. Action this week: Follow Hemispheric and watch for an actual FDA filing rather than assuming this launch means it's available. Share this with whoever in your life does that kind of intake work — a doctor, a therapist, a case manager — because when this clears, they're the ones who'll hear about it first.

» What to watch this week

Whether the Board of Public Utilities' tariff standards actually name heat pumps, solar, or batteries as the currency of New Jersey's data-center trade. The law authorizes the mechanism; the BPU's rulemaking decides whether it's real money for ratepayers or a vague framework nobody uses.
What Sunrun actually pays homeowners, and whether it names a compute buyer. "Proves out" is unproven at this scale until there's a real dollar figure and a real customer on the other end of the deal.
Whether Talk to Spotify expands past three countries and beta, and whether the hallucination risk on complex questions becomes a real complaint. A beta confined to Premium subscribers in three countries is a different product than what ships to everyone.
Whether Hemispheric files with the FDA, and on what timeline. "Shown architectural data to the FDA" is not a clearance; the filing is the next real milestone, not this week's funding news.

Tomorrow's signal lands here.
