What does the abbreviation EENS stand for in the context of energy management?

The abbreviation EENS stands for Expected Energy Not Supplied. This concept is critical in energy management as it quantifies the amount of energy that is expected to be unavailable to meet demand due to system constraints, planned outages, or other disruptions. By calculating EENS, utility managers and planners can assess reliability and make informed decisions about investments in infrastructure or changes in operational strategies to enhance service reliability.

Understanding EENS helps in evaluating the trade-offs between costs of energy supply and the impacts of energy shortages on consumers and the economy. This metric is pivotal for utilities in their reliability assessments and for regulatory compliance, ensuring that adequate measures are in place to minimize energy supply disruptions.
