Electricity companies must rely on a high level of availability of their various assets in order to meet their clients’ needs in an ever changing marketplace. In order to achieve this objective, these assets must be kept in a reliable condition, thus requiring outages to perform recurrent annual maintenance, multiannual major overhauls and refurbishments. In addition to the planned outages that are required, forced (or unplanned) outages will unfortunately happen as a result of unforeseen events.

Factors to consider in the optimal planning and scheduling of outages include the effects of electricity competition, regulation and environmental requirements and impacts to minimize losses (e.g., revenue losses) due to equipment downtime.

HOPIG members believe that a Maturity Matrix, utilized as a visual and illustrative communication tool, is an efficient way to document processes and to compare the activities performed by an organization with the best known practices, leading to plans for improvements.

In building a Maturity Matrix, this project provides the opportunity to produce an inventory of what is accomplished in the field of Outage Planning. It covers all activities for Outage Planning including the scheduling and impact evaluation of outages in the forecast mode, the evaluation of actual outage impacts computed after the fact, and issues pertaining to efficient communications within the organization.
