Preparing for EMS Implementation: 7 Steps Before Energy Starts Eating Into Your Margin

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.

Step 1. Define why your manufacturing plant needs an EMS system

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.

What is an EMS system for?

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.

Step 2. Choose the area where energy has the biggest effect on cost

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.

Step 3. Check what data you already have

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.

Step 4. Connect energy with production

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.

Step 5. Set 3 to 5 goals

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.

Step 6. Assign responsibility

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.

Step 7. Start with a pilot

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.

Where does a well-implemented EMS system really help?

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.

Checklist before EMS implementation

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.

Before you implement EMS, prepare your company to make decisions

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.

FAQ: Preparing for EMS Implementation

Why does a manufacturing company need an EMS system?

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.

Does EMS implementation have to start across the whole plant?

No. It is often better to start with one area, such as a production line, compressor room, or cold storage area.

What data is needed for EMS?

At the start, you need data on energy and utility consumption, production, downtime, production orders, shifts, and energy costs.

How is EMS different from regular energy monitoring?

Energy monitoring shows consumption. EMS helps manage energy by connecting consumption data with production, goals, costs, and team responsibility.

Preparing for MES implementation can be easier with guidance. Let's talk and plan it together.
