You can have modern machines, a good team, and a full production schedule, and still lose money on energy. That’s why preparing for EMS implementation can be a logical next step.
A well-prepared Energy Management System (EMS) does more than show energy consumption. It helps you find cost faster, assign it to the right area, and make a decision before the same problem shows up again next month.
Most of the time, the issue is not that someone forgot to check something. More often, the company simply does not have the data needed to see where the cost is created. There can be many reasons, for example:
An EMS system can show you that. But before it starts helping, you need to know what to measure, why you are measuring it, and who is responsible for reacting. That is why preparing for EMS implementation should be treated as the first stage of energy management.
Do not start with meters, dashboards, or integrations. Start by asking yourself and your team: what do we want to see better with EMS?
It may be energy cost per product, machine operation after hours, power peaks, compressed air, or data for ESG, ISO 50001, or an energy audit.
An EMS system helps energy stop being a general plant cost and become a cost assigned to a place, time, product, and decision.
According to the IEA, companies that implement energy management achieve, on average, around 11% energy savings in the first years. That is not a guarantee for every manufacturing plant, but it is a strong reason to base decisions on data.
You do not have to start energy management across the whole plant. It is often better to begin with one area where energy has a strong impact on operating costs.
A good starting point may be:
Example: A compressor consumes 25 kW outside production hours from Friday evening to Monday morning. At a price of PLN 0.75 per kWh, that is about PLN 1,050 in one weekend and over PLN 54,000 per year.
A well-prepared EMS shows that consumption to the right person, at the right moment, with cost context.
Very often, the data already exists, but it is scattered across meters, the production system, invoices, spreadsheets, and team knowledge.
Before EMS implementation, organize it.
| Area | What to check | Why |
|---|---|---|
| Meters | What they measure and whether remote reading is available | To understand your starting point |
| Utilities | Electricity, gas, water, cooling, compressed air | Because cost is not only electricity |
| Production | Production orders, quantities, shifts, downtime | To calculate cost per product |
| Costs | Tariffs, contracted power, fees | To convert kWh into money |
| Systems | PLC, SCADA, MES, ERP, API | To know what can be connected to EMS |
EMS is not about collecting as much data as possible. It is about using data that helps you make better operating decisions.
The number of kWh alone is not enough. Two production lines may use a similar amount of energy but have a very different energy cost per product.
That is why EMS implementation should lead to indicators such as:
Example: Line A uses 310 kWh per 1,000 units, while Line B uses 430 kWh per 1,000 units.
Only when energy data is connected with production data can you see where to look for the cause: changeovers, micro-downtime, start-up, machine settings, or differences between shifts.

A goal such as “reduce energy costs” is too general and can create unrealistic expectations. Better goals sound like this:
| Goal | Indicator | Who should see it |
|---|---|---|
| Lower product cost | kWh/unit, energy cost per production order | Production, controlling |
| Less energy during downtime | kWh outside line operating time | Production, maintenance |
| Power peak control | Maximum power demand | Energy manager, management board |
| Better compressor room operation | Consumption after hours | Maintenance |
If an indicator makes sense, someone should review it regularly.
The system will show a deviation. An alert will reach the team. But what happens next?
If responsibility is not defined earlier, everyone will see the problem, but no one will feel responsible for solving it.
| Role | Responsibility |
|---|---|
| Management board or plant manager | Defines what business effect EMS should deliver |
| Energy manager | Analyzes consumption, tariffs, and deviations |
| Maintenance | Reacts to failures and equipment running after hours |
| Production | Connects energy consumption with shifts, production orders, and downtime |
| Finance / controlling | Converts consumption into product or department cost |
You need to know who reacts when EMS shows a problem.
Without that answer, the system may collect good data, but the company will not use its full value.
A pilot should cover a well-chosen part of the plant and show whether the data helps people make better decisions.
It may include:
After the pilot, check whether the data is reliable, whether alerts reach the right people, and whether EMS helps the team find the source of cost faster.
The pilot does not need to be large. It needs to clearly show how the system supports everyday work.
An EMS system helps you monitor, analyze, and optimize the consumption of electricity and other utilities in real time. It can work as a standalone system or as a module within a wider environment, such as the Production Portal. It connects energy data with production data.
With that connection, you can check:
Instead of saying, “We used too much energy,” you can say:
This line had a higher energy cost per 1,000 units because changeovers took longer and auxiliary equipment kept running during downtime.
With that information, you can take specific action.
Check whether you can mark these points as done:
If some points are still unchecked, it is a good moment to organize the basics before the start.
EMS will not lower bills on its own. The team will do that when people see the right data, understand the cost, and know how to react.
Preparing for EMS implementation helps you start with the right questions:
If you want to go through these 7 steps using data from your own manufacturing plant, let’s talk about EMS implementation in your facility. We will help you choose the starting area, indicators, and data workflow so energy becomes a cost you can manage day by day.
An EMS system helps you see where the company uses energy, when the highest costs appear, and which areas require action. It also makes it easier to calculate energy cost by product, production line, or production order.
No. It is often better to start with one area, such as a production line, compressor room, or cold storage area.
At the start, you need data on energy and utility consumption, production, downtime, production orders, shifts, and energy costs.
Energy monitoring shows consumption. EMS helps manage energy by connecting consumption data with production, goals, costs, and team responsibility.
