THE PRODUCT
One Powerblock
means 1-3 months off your bill
A lean financial product for a month off your bill. The unit is the size of a refrigerator, sits outside, and runs silent, insured, and automatic. $0 upfront, fully funded by Powertown, with no operational disruptions.
Quiet, clean, small, no operational disruptions. We designed this to make it easy to say yes to. The unit is the size of a refrigerator, sits outside, and runs silent, insured, and automatic.
1-3 months off your annual bill with no operational disruption.
We charge when electricity is cheap and discharge when electricity is expensive or valuable, Units are behind-the-meter and the size of a refrigerator.

Where does the money come from?
Your unit turns the mess of the grid into a financial asset for your business by reducing demand fines and protecting your electric bill against rising costs. Utilities fine large commercial customers based on their single highest demand spike each month — often just 15 minutes. The only way to avoid it is to turn power off when your business needs it. One spike represents 30–70% of your entire bill. The dollar charge is increasing nationwide. The Powerblock fixes that by charging when electricity is cheap and kicks on automatically during your peak window to smooth your peak and reduce your fine. Your operations don't change. We share the savings — leaving you with about 1 to 3 months off your bill per year.
Have other people done this?
Battery storage is standard infrastructure across California, Europe, and Asia — typically paired with solar, and increasingly deployed standalone. More than 3,000 commercial buildings in California alone are already running systems like this. The hardware we use, Chint Power, is operating at hundreds of those sites today. You're not an early adopter. Massachusetts just hasn't had an accessible path to it until now.
Can it affect my power service?
No. The Powerblock runs on its own dedicated circuit — completely separate from your equipment. It's connected in parallel, meaning it sits alongside your power supply, not between the utility and your building. If it goes down, your operations don't notice. This happens for three reasons: Software keeps risk isolated The Powerblock's brain monitors every cell constantly. If it detects anything wrong - heat, a bad circuit, abnormal current - it cuts power at the source. Hardware keeps risk isolated If one cabinet has a problem, the fuse blows and isolates it before the power combines and moves toward your building. Facility keeps risk isolated A dedicated 400A breaker keeps the Powerblock on its own circuit and prevents it from exporting more power, keeping the system completely separate from your equipment.
Why is it this small?
We choose the size for for speed and simplicity — 250kW means faster utility approval and avoided permitting hurdles, so your project moves quickly.
What does Powertown contribute?
Without our software, the Powerblock is just a box. We also coordinate all installation and maintenance. Most of our company focuses on coordinating the cohort, but we commit to excellence on your unit before all else.
How long does the Powerblock last?
15 to 20 years. We typically recover our costs by year two or three. After that, your share of the savings increases significantly and stays that way for the life of the system.
THE COHORT
It's not just savings: 20 Powerblocks Builds us Legacy Infrastructure
It's not just savings, it's a new civic missin. The only catch is that we need 20 to unlock a $10 million investment in the city. 20 Powerblocks shifts load in real time, responds to grid stress as a unit, and becomes a resilience and affordability multiplier for the local power grid.
How is this different from solar?
Solar generates power from sunlight and feeds it into your building or back to the grid. Storage captures power that already exists and releases it at the right moment to cut your costs. They solve different problems — and they work well together. A Powerblock makes your existing solar installation more valuable by storing what it generates instead of exporting it at a low rate. If you don't have solar, a Powerblock still works on its own.
How is it different from demand response?
Traditional demand response programs ask you to curtail your operations during peak events — meaning you turn things off or slow down to reduce your load. We never ask you to do that. Your Powerblock handles the response automatically by discharging stored energy, so your equipment keeps running at full capacity. You get the program revenue without the operational interruption.
What happens if it malfunctions?
We own the unit and we monitor it remotely around the clock. If something goes wrong, we know about it before you do. Maintenance, repairs, and replacements are our responsibility for the life of the agreement. You have one number to call. In most cases you won't need to call at all.
Will it cause voltage flickers or disrupt our equipment?
No. This is one of the most common concerns we hear, and the answer is straightforward. A Powerblock is not a generator. It does not switch your building onto a separate power source. It runs in parallel with your grid supply at all times, operating in milliseconds alongside it. There is no transfer, no momentary dropout, and no voltage event of any kind. Sensitive equipment — CNC machines, refrigeration systems, medical devices, manufacturing lines — will not notice it is there. If anything, a Powerblock improves power quality by smoothing the demand curve and reducing the kind of load spikes that can themselves cause flicker.
How is this actually no cost?
We own the Powerblock. We pay for it, install it, and operate it at our cost. In exchange, we take a share of the savings and revenue the system generates. You keep the rest. This is called an Energy Service Agreement. It is the same structure that made solar accessible to millions of commercial buildings over the last decade — instead of asking you to buy a system, we invest in it ourselves and share what it earns. The reason we built it this way is alignment. We only make money when the system performs. If we miss a peak event, we take the hit, not you. That keeps us focused on doing the job well, maintaining the equipment, and optimizing every revenue stream — because our return depends on it.
How long does the Powerblock last?
15 to 20 years. We typically recover our costs by year two or three. After that, your share of the savings increases significantly and stays that way for the life of the system.
