Energy Management

The cycle is divided into four phases.

1. Plan

The goal of the first phase is to define the energy policy, set energy targets, and collect relevant data.

• Measures:
  • Analyze energy consumption (e.g., through energy audits and energy monitoring).
  • Identify energy saving potential.
  • Formulate energy targets and action plans.
  • Define responsibilities.

Example:

A company notices that electricity consumption in production is particularly high. Energy data is collected and analyzed. The goal is to reduce electricity consumption by 10% within one year. As a measure, old machines are replaced with more energy-efficient models, and load management is introduced.

2. Do

The goal of the second phase is to implement the planned measures to improve energy efficiency.

• Measures:
  • Installation of efficient technologies.
  • Training of employees.
  • Introduction of energy management software.
  • Implementation of energy-saving projects.

Example:

In our example, the new machines are installed. An energy monitoring system is introduced and employee training on energy-efficient behavior takes place.

3. Check

The aim of the third phase is to evaluate the results of the measures and compare them with the targets.

• Measures:
  • Monitor energy performance indicators (EnPIs) with energy monitoring
  • Analyze deviations.
  • Conduct internal audits.
  • Create reports.

Example:

The consumption data of the new machines is evaluated. The evaluation shows that electricity consumption has already fallen by 7%. Further optimizations are examined (e.g., through better utilization).

4. Act

The aim of the fourth phase is to use findings from the review to improve processes.

• Measures:
  • Initiate corrective measures.
  • Adapt processes.
  • Update energy targets.
  • Conduct management review.

Example:

The new processes are incorporated into the operating instructions. Further measures are planned, e.g., optimization of lighting or heat recovery. A new PDCA cycle is started to achieve further savings on an ongoing basis.
