AI in energy

AI that predicts, balances and saves — before anyone has to climb a turbine.

We're an AI-first product team. We add AI where sensor data turns into fewer failures, lower bills and smarter use of every kilowatt-hour.

Discuss your AI use case

Predictive maintenance

Spots unusual vibration, heat or output in turbines, inverters and chargers — and flags them before they fail.

FAQ

Questions energy founders ask us.

Didn't find yours? Ask us directly — we reply within 24 hours.

How much does it cost to build a green energy app?

It depends on devices, protocols, platforms and dashboards. A focused MVP typically ranges from $10,000 to $30,000; we give you a detailed estimate after a free discovery call.

How long does development take?

Parkworks, our EV charging app, launched in 6 months; Enact’s solar and battery app in 8. A first MVP can be ready in about 2 months.

Which devices and protocols can you connect?

Solar inverters, batteries, smart meters, EV chargers, HVAC and home devices — over MQTT, Bluetooth LE, OCPP, Modbus or your own API, via AWS IoT Core or Azure IoT Hub.

Can you add AI to our energy product?

Yes. We start with the use case with the clearest payback — usually predictive maintenance or usage forecasting — prove it on your data, then roll it out with human approval for any device action.

How do you keep device data and control secure?

Encrypted connections, role-based access, audit logs for every command and GDPR-compliant handling of home and meter data.

Does Perpetio have energy and IoT experience?

Yes — from Enact’s solar and battery app and Parkworks’ EV charging app to a smart meter app, a smart HVAC remote control and Alterra’s utility metering for commercial property.
