The Changing Face of Power Plant Statistics: New Changes to IEEE 762 and GADS

For the last three years, GADS Services of the North American Electric Reliability Council (NERC) has worked with other members of the Institute of Electronic and Electrical Engineers (IEEE) to review and improve the IEEE Standard 762, “Definitions for Reporting Electric Generating Unit Reliability, Availability and Productivity.” IEEE 762 is the basis of equations and definitions for the NERC Generating Availability Data System (GADS). With the help of North American, European and South African colleagues, the IEEE 762 has moved closer to that used in other parts of the world. This paper explains several major changes to IEEE 762 to bring about the compatibility. It also mentions some applications that are used by NERC GADS.
