SEMT was founded with one clear goal: helping businesses scale their energy consumption, so that energy is not a brake on commercial growth, but a driving force.
We believe the energy transition is not only a technical challenge, but also an opportunity. An opportunity for entrepreneurs to operate smarter, reduce costs, and at the same time relieve pressure on the energy grid. We do this by building a strong network of entrepreneurs who together contribute to a more stable energy infrastructure.
At SEMT, we never do this alone. We work with you as a partner – not as a supplier.
For most businesses, energy is one of the largest cost items — and at the same time the item that is managed least actively. While energy prices fluctuate every quarter-hour, your installation sits waiting for a signal that never comes. The opportunities are there every day. The only question is whether you are seizing them.
Businesses that do not actively manage their energy not only pay too much. They also miss the chance to recoup their investment in solar panels and batteries faster, avoid peak costs, and contribute to a more stable energy grid. These are not small amounts, and these are not vague promises. The results from our pilots speak for themselves.

Bedrijven die hun energie niet actief managen, betalen niet alleen te veel. Ze missen ook de kans om hun investering in zonnepanelen en batterijen sneller terug te verdienen, piekkosten te vermijden en bij te dragen aan een stabieler energienet. Dat zijn geen kleine bedragen en het zijn geen vage beloftes. De resultaten bij onze pilots spreken voor zich.

Almost every battery sold today comes with an energy management system. That system handles the basic flows: it charges when there is sun and discharges when there is demand. For many entrepreneurs, that feels sufficient. But it is not the same as optimal.
A standard EMS reacts to what is happening now. It does not look ahead. It does not know that energy will be exceptionally cheap tomorrow morning between six and eight, or that the purchase price will peak this afternoon. It charges and discharges based on the moment, not based on the best strategy.
SEMT works differently. Based on expected solar hours and the energy purchase price, the system creates a plan up to 36 hours ahead, as far as published prices and forecasts reach, broken down by quarter-hour. You can see in advance how much savings are expected and how your installation will be deployed that day.
But a plan is not a guarantee – and we know that.
That is why SEMT adjusts every fifteen minutes. If reality deviates from the plan – unexpected cloud cover, a price spike, a shift in demand – the system adapts immediately. So at every moment of the day, the best possible strategy is applied, automatically and without manual intervention.
That is the difference between a system that reacts and a system that optimises. And that difference is precisely what determines how much your investment in solar panels and batteries ultimately yields.
The Energy Butler is not a system that leaves you on your own after installation. It is a digital energy manager that is active 24/7, understands your business, and at every moment of the day applies the strategy that best suits your situation. Not one fixed strategy, but multiple — by the hour, aligned with what the grid is doing, what the sun is providing, and what energy costs at that moment.
What does this mean in practice? You know in advance what to expect. The Energy Butler makes clear how much you will save, when your installation does what, and what the expected costs are. No surprises afterwards, but full transparency in advance. That insight is not a side note — it is the core of how we work.
Maximum autonomy. Your business runs as little as possible on the grid and uses every kilowatt-hour of your own generation.
Feed energy back to the grid at the most favourable moment, maximally relieving the grid and optimising your return.
Prevent peak loads. The system monitors your consumption profile and intervenes before you draw expensive capacity.
The installation requires no major work. Within half a day, the Energy Butler is operational and you have immediate insight into your energy consumption. From that moment on, the system works for you — in the background, without hassle, with one goal: increasing your margins and allowing your business to scale further.
A standard EMS does what it should. The Energy Butler does what it can. By planning up to 36 hours ahead and adjusting every five minutes, the system consistently gets more out of your solar panels and battery than a conventional system ever could. How much more depends on your installation, your consumption and your energy contract — and it needs no additional investment in hardware.
For many businesses, peak loads are a creeping cost problem. Grid operators charge heavily for the capacity drawn at peak moments, and those costs add up quickly. Not to mention the commercial opportunities that remain untapped due to scalability constraints. The Energy Butler continuously monitors your consumption profile and ensures you never unnecessarily exceed your peak load. That means lower grid costs, but also that you need to invest less quickly in additional battery capacity. The system makes smart use of what you already have.
The Dutch electricity grid is under significant pressure. In more and more parts of the country, maximum capacity has been reached, making new connections almost impossible. The Energy Butler is built with the grid in mind. At times when the grid risks becoming overloaded, the system automatically reduces consumption. And when there is a surplus of energy on the grid — and the price is low — the system actively draws more to make productive use of that energy. This way, every business using the Energy Butler contributes to a more stable and fairer energy grid for everyone.
