“Hanley Energy’s solution started with a comprehensive assessment to understand how energy was used. A bespoke and modular energy monitoring system was installed. This support has allowed me to understand how and where energy is used; it allows me to manage energy in a structured way and is an essential building block for compliance to ISO 50001.”
