Tariff Smart Energy Intelligence

Your battery is smarter than the schedule it's running on.

WattChop is the platform that puts an algorithm between your tariff and your battery — so the system keeps pace with markets, weather, and rates for the life of the investment. Free analysis for every project. No credit card.

The Opportunity

The battery is the only part of your energy system that can decide.

Solar panels take what the sun gives them. Meters measure what already happened. The battery is the only piece of the stack that can actually make a choice — when to charge, when to hold, when to discharge.

Most battery systems are wired to a schedule. A sprinkler timer for electricity. Charge at night, discharge in the afternoon, repeat forever. But markets aren't static. Weather isn't static. Tariffs aren't static. A battery running on a schedule is wasting its only real advantage.

“Set it and forget it” was the only option. Until it wasn't.

The Algorithm

Meet the Choptimizer.

WattChop is the platform. The Choptimizer is the algorithm that runs it. It knows the time value of energy — hour by hour, season by season, tariff by tariff — and builds an operating schedule your battery can follow to maximize the savings. It works best where the math gets interesting: time-of-use rate structures and high demand charge windows.

Day One

Solve for Max Savings

The Choptimizer reads your tariff, your building, and your interval data — and solves for the system that delivers the maximum savings. Not the biggest. Not the cheapest. The one the math supports. The answer comes back as an Analysis Report that pairs with your EPC's proposal — the methodology behind the savings number, documented and defensible.

Every Day After

Rewrite the Schedule

Markets move. Weather changes. Tariffs evolve. The Choptimizer rewrites the dispatch schedule as often as your site needs — seasonal, monthly, or daily. Every night it pulls tomorrow's weather forecast — cloud cover, solar radiation, temperature — and plans the next 24 hours around what's actually coming.

Every Year of the Investment

Prove the Savings

The savings promised become the savings measured. The same algorithm that sized the system proves it's still earning its keep. Year one. Year ten. Year twenty-five.

One algorithm. Every stage. For the life of the investment.

“How do you control a battery?”

It depends. Dozens of ways — direct hardware commands, BMS integrations, EMS platforms, inverter APIs. We don't build any of them. What we build is the schedule: a 24-hour dispatch map of charge, hold, and discharge setpoints that your battery — or your EMS partner — follows.

Hardware is hardware. We're the intelligence that tells it what to do.

Free Tools

Free energy analysis for every project.

The only way the Choptimizer gets sharper is by seeing more buildings. So the parts that don't need to be paid for, aren't. Come one, come all.

More tools coming. This is just the beginning.

Building DNA

28 Building Types. One smart synthesizer.

Every building breathes in a pattern. A grocery store's load profile looks nothing like a data center's. A school peaks differently than a hospital.

WattChop uses validated data sources to group buildings by how they consume energy, then uses that similarity to deliver results backed by data — not guesswork. Even without interval data, the synthesizer builds an accurate load profile from monthly utility bills.

Every project makes the Choptimizer sharper. More buildings, more patterns, better recommendations for the next project in line.
