PES stands for the IEEE Power & Energy Society. It is the main professional organization for engineers, researchers, and technicians working in electric power generation, transmission, and distribution. The society develops industry standards, publishes technical journals, and organizes conferences that shape the design and operation of the grid.
Heard on the job
I found a great paper on transformer dissolved gas analysis in the PES transactions.
Insider tip
Originally known as the Power Engineering Society, it was renamed to the Power & Energy Society to reflect the integration of renewable energy sources.
