Energy is one of the top operating expense to organizations and the use of non-renewable energy sources is getting more expensive which would eventually lead to more expensive production of goods and services, therefore it is becoming necessary for organizations to get involved in Energy Management.
ISO 50001 is an International standard for Energy Management Systems which aims at helping organizations to continually improve on their Energy Efficiency thereby reducing their energy use and cost which would in turn bring financial gains for the organization.
Energy Management is defined as a strategy adopted for adopted for optimizing Energy using systems and procedures to reduce energy while keeping the cost and uninterrupted energy supply in consideration. However before implementing Energy Management System, it is important that Energy Audit be performed; that is, a systematic approach for inspection and analysis of energy consumption to identify energy flows and potential for improvements.
The Energy Management System (ISO 50001:2018) gives a list of requirements and conditions which must be met by organizations before they can be certified, the system also follows the PLAN, DO, CHECK, ACT cycle and can be integrated with other management systems that already exists within the organization. There are three stages of implementation; stage one phase is where audit is done and quick fixes are immediately applied, the stage 2 phase requires targets to be set and initiation of strategic projects begins while in the stage 3 an internal audit is performed to check for the efficiency and effectiveness of the implemented projects and also to ensure that there is room for continual improvement after which certification can be applied for.
It is important to note that Energy Performance Indicators (ENPIs) must be defined which can be used for benchmarking. ENPIs may differ from company to company depending on their operations and structure so it is advised that each company develops its own unique Energy performance indicator. Adequately defined ENPIs allows for continual improvement.
Benefits of implementing an Energy Management System include;
- Efficient use of resources
- Protecting the environment
- Cost reduction
- Improving energy performance
