The energy transition is accelerating. More and more companies are struggling with rising energy costs, grid congestion, and limited expansion options. Smart energy management is becoming standard. At EVALAN, we are developing Wattmaestro: the business energy management system (EMS) that goes beyond the standard.
In 2025, we took significant steps to strengthen our position in this rapidly growing marketโwith new partnerships, a refreshed look, and a clear focus on installers who think in terms of complete energy ecosystems.
Built on twenty years of IoT experience
Wattmaestro originated within EVALAN, which has been developing IoT solutions for organizations like Heineken, Van Wijnen, and the Ministry of Defense for twenty years.
This background ensures a robust technical foundation: from our own gateway (BACE+) and firmware to the cloud software and online dashboards. Everything has been developed entirely in-house and optimized for security, reliability, and scalability.
โWe donโt just build an EMS, we build trust,โ says Henk Schwietert, CEO of EVALAN. โInstallers need to know that it works. All the time.โ
For installers who think beyond one system
The role of installers is changing. They are increasingly being asked to not only install solar panels or charging stations, but to optimize a company’s entire energy system.
Wattmaestro was developed for these system-oriented installers: professionals who want to manage the entire systemโsolar, storage, heat, mobility, and energy consumptionโrather than individual components.
With Wattmaestro, they get a single, transparent platform that connects, monitors, and automatically controls all their energy installations. The result: lower energy costs and satisfied customers who remain flexible for future expansions. And fewer unnecessary trips for installers themselves.
Growth in projects and collaborations
Over the past year, Wattmaestro has grown into the EMS that is increasingly being used by more partners for complex energy issues. For example, we have worked with Zonzo, Energie Aalsmeer, Devcon, Pipelife, NXT Mobility and various system integrators to connect energy installations more intelligently and utilise them better.
From an SME that uses its solar power smartly for maximum self-consumption, to a production location with 3 MWh daily consumption that runs completely off-grid โ Wattmaestro proves itself every day as a reliable conductor of diverse energy systems.
Every successful installation not only delivers energy savings, but also trust and knowledge for further scaling up.
Innovation in features and applications
Our technology continues to develop. Wattmaestro now offers a wide range of features that allow installers and entrepreneurs to manage their energy smartly:
- (Dynamic) Curtailment: prevents back-feeding during negative electricity prices.
- Load Shifting: shifts energy consumption to times with low prices.
- Battery Optimization: charges and discharges at exactly the right time.
- Backup Control: manages local emergency scenarios directly via the gateway.
- Energy Trading: connects directly to markets such as EPEX and imbalance.
These features not only save money, but also reduce COโ emissions and ensure optimal use of grid capacity.
Looking ahead to 2026
In 2026, we will continue this path firmly. In an increasingly complex energy market. The focus will be on:
- Adding even more features, markets, and data;
- Expanding our installer partner program;
- and further strengthening our position as a reliable, brand-independent EMS in the Netherlands.
Our goal remains clear: to help Dutch organizations grow within their existing grid connection, while installers can confidently build on technology that works.
