- What is an energy management system (EnMS)
- Benefits of energy management systems
An energy management system (EMS) is a system of computer-aided tools used by operators of electric utility grids to monitor, control, and optimize the performance of the generation and/or transmission system. The computer technology is also referred to as SCADA/EMS or EMS/SCADA.
Establishing an EnMS requires you to:
- Develop and implement an energy policy
- Identify your main energy users
- Set energy objectives and measurable targets
- Implement and operate programmes to meet these objectives and targets
- Check and take corrective action as required
- Review your system continually and improve where possible
- Continual improvement, which is a key feature of the standard, ensures that you remain alert for new opportunities as they arise and exploit all areas where energy savings can be achieved
The main benefits of an EnMS are that it
- Instills best-practice energy management in your day-to-day operations
- Improves your performance and productivity
- Reduces your energy costs
- Helps you to comply with your energy-efficiency and emission-reduction obligations
- Standardises processes so that improvements are sustained over time
Long term benefits
- As the system matures, your energy management becomes more effective. You can continuously improve your energy performance at a faster pace. And energy awareness becomes part of your organisations’ work culture.
- You reap great strategic benefits by:
- Reducing your energy use over the long term
- Cutting your costs year-on-year
- Influencing the energy requirements of the entire value chain
- As well, by maintaining a certified energy-management system, you demonstrate publicly your corporate social responsibility.
