Picture this: you walk into a perfectly comfortable home at 72–74ºF. Your EV charges in the middle of the night when your electricity is the least expensive. Hot water is ready for showers. Laundry finishes right on time. And then the bill arrives — and it’s 30–60% lower than what you paid before. That’s everyday life with Interactive Energy Systems.

Utilities across the country are moving more customers onto TOU‑D plans and adjusting prices upward to handle grid strain.
Without active demand control, bills go up… and up… and up. With automation, you keep the luxury lifestyle you want — and the bill you deserve.
Most homeowners don’t realize their biggest billing risk isn’t how much electricity they use — it’s the most at once. In TOU‑D markets, utilities measure the single highest 15‑minute spike in your usage and base a monthly demand charge on that peak. If your AC cycles, water heater fires, dryer tumbles, and EV charger kicks on during the same quarter‑hour, that spike can inflate your bill for the entire month.
The Demand Automation Computer solves this quietly and automatically. It monitors your high‑load appliances in real time and choreographs when they run so they work in harmony, not in conflict. Comfort never changes; chaos disappears. Because demand stays low, so does your bill.
We’ve never needed tax incentives to make our math work. There are no roof panels to install, no permits for arrays, and no lifestyle sacrifices. The technology is built in the USA, certified by UL, backed by a 5‑year warranty, and has delivered a <1% historical failure rate across more than 35,000+ installations — including 25,000+ in Arizona and 10,000+ across North Carolina, South Carolina, and Virginia. We are pleased to announce that we are now serving Georgia Power customers in the great state of Georgia. We will be opening up the ability for customers to save on their monthly electric bills to our dear friends in the incredible state of Missouri very soon.

We start with a deep dive into your home’s energy profile, historical demand data, and utility rate structure to identify cost-saving opportunities.
Our team designs your custom tailored load-shedding plan, prioritizes equipment groups, and set demand limits that align with your optimal lifestyle and desired savings.
Certified electricians install the Interactive Energy Systems Demand Automation Computer, integrate it with your loads, and calibrate it to maximize your comfort, minimize your costs and optimize all of this while capping peak kW.
We provide obsessive support both before and after your installation. Our expert support team is dedicated to keep your system optimized and your savings maximized over time.
Most customers save between 30% and 60% on their electric bills, depending on their utility’s demand rates and the demand limit they set. Managing non-critical loads lets you take advantage of lower rates and maximize every kilowatt-hour you pay for.
The majority of users see a full ROI within 1–5 years. After the system pays for itself, all the savings go straight to your bottom line — year after year.
Think of it like cruise control for your home. Energy Sentry smooths out peaks and valleys in energy use, keeping your demand charges low while making your energy consumption more consistent and efficient.
