Units are code compliant.
If they do not connect to your site safely, we do not deploy.

From the battery, to the system, to the fire code, to the grid, every Powerblock arrives at your site already certified with applicable safety standards. Here is what that means:

Commercially Certified

UL 1973 — battery pack safety

UL 9540 — full system safety

We confirm with local building/zoning officals

Fire Tested

UL 9540A — fire behavior testing ensures it's contained

NFPA 855 — site installation code

We confirm with your local marshal

Grid-Compatible

UL 1741 SB — inverter safety

IEEE 1547:2018 — grid interconnection standard

We confirm with utilities

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.

FAQs

We are a turnkey solution

You apply and we visit

We require three quick uploads to determine the value your site has. We like to schedule a brief site visit to meet you and confirm the physical setup.

Engineer selects safe installation method

There are three options to connect the unit to your site: panel connection, junction box intercept, or transformer lug tap. Our licensed electrical engineer picks the one that is fastest and best suited to your building.

Powertown

We get you a proposal

Our software runs a full simulation of your building's savings potential and projected revenue across every value stream. We move forward if the economics and safety work for everyone.

Powertown

We permit

We pull permits and apply for interconnection. Battery storage permits more like an electrical appliance than a large infrastructure project, and Massachusetts is actively streamlining the process.

Powertown

Electrician installs

Installation typically takes two days. We schedule it to minimize any disruption to your operations . Our network of experienced electricians has installed systems like this before and knows exactly what to do.

Powertown

We operate and maintain

Our energy management system delivers value that we share with you to pay back our system costs. You get more every year. We handle all maintenance for the life of the system.
