ENGINEERING-GRADE EMS

the engineering grade energy management system

OUR MISSION

We're Wattmaestro. We tackle grid congestion by unlocking on-site flexibility. We build for clients who run critical infrastructure and operate sites that can't afford to fail.

We call it engineering-grade EMS. Pairing a product approach with an engineering mindset, to take on the projects others call too complex.

OUR STORY

Twenty years of

connecting the unconnected

Wattmaestro grew out of Evalan, an Amsterdam engineering company that has spent more than twenty years building connected systems for organisations that can't afford failure. Heineken. The Dutch Ministry of Defence. Many more. Over 30,000 assets in the field, on hardware, firmware and software we design and build ourselves. Twenty years of industrial IoT teaches you one thing: the real world is messy. Assets speak different languages. Documentation goes missing. Manufacturers disappear. We believe that future proof energy systems are engineered end to end, by people who own every layer and answer for all of it. So we built Wattmaestro. One team. One stack. From the gateway on the wall to the dashboard on the screen.

OUR VALUES

Three things

we do not compromise on.

Reliability

System you can build on. On sites were failure is not an option.

Engineering depth

Not a standard EMS vendor. An EMS with engineering behind it.

Ownership

One team owns the whole stack. So one team owns the answer. No gaps between suppliers. No finger-pointing.

TEAM

Get to

know us

40+ people, one floor in Amsterdam. The engineer who designed the gateway sits next to the one who wrote the dashboard. That is not a detail. It is why an integration that takes three vendors a quarter takes us a conversation. There is always someone in the room who built the layer your question is about.
