Power plant performance indices in new market environment: IEEE standard 762 working group activities and GADS database

As the electric power industry moves towards a new market environment, it became necessary to review and modify existing indicators of power plant performance. Thus, the IEEE created a review team of power plant experts to review and update IEEE standard 762, "definitions for use in reporting electric generating unit reliability, availability, and productivity" to meet the needs of the industry. This paper highlights some key (not all) activities of the IEEE standard 762 working group over the last three years. It also highlights how the North American Electric Reliability Council\´s (NERC) generating availability data system (GADS), a big supporter and user of IEEE 762, uses these new modifications in its reports and training of data reporters. A short discussion of why commercial availability and market monitoring were discussed by the working group but not included in the revised standard 762 is presented
