The US Department of Energy 2010 report ‘Operations and Maintenance Best Practices’ concludes the following:

‘Effective O&M is one of the most cost-effective methods for ensuring reliability, safety, and energy efficiency. Inadequate maintenance of energy-using systems is a major cause of energy waste in both the public and the private sector. Energy losses from steam, water and air leaks, uninsulated lines, maladjusted or inoperable controls, and other losses from poor maintenance are often considerable. Good maintenance practices can generate substantial energy savings and should be considered a resource. Moreover, improvements to facility maintenance programs can often be accomplished immediately and at a relatively low cost.

O&M management is a critical component of the overall program. The management function should bind the distinct parts of the program into a cohesive entity. 

From our experience, the overall program should contain five very distinct functions:

 Operations, Maintenance, Engineering, Training, and Administration
