Implementing an energy management system (EnMS) can result in many benefits, such as cost and energy savings, and when established across multiple organizations, these benefits are even greater. A common EnMS enables the sharing of knowledge and resources as well as collaboration on energy-saving projects across organizations of all kinds and sizes. This includes SMEs too.

ISO 50009 Energy management systems – Guidance for implementing a common energy management system in multiple organizations, is aimed at uniting organizations that have some common element, such as energy supplier, sector or location, to optimize their energy use collectively, whatever their size.

An EnMS is a framework for energy management covering organizational policy, targets, action plans and ways of measuring progress. Extending it across multiple organizations allows for collaboration and common goals that will ultimately lead to greater savings and energy efficiency.
