Today’s LiveWire Spotlight looks at the initial version of a NERC support document describing the best practices employed by planners and operators to assure sufficient Reactive Power is available to avoid BES voltage instability. It finds that future NERC standards may be needed to address the effect of Reactive Power flows on voltage at the boundaries between generation, transmission, and distribution systems.

Draft 1 of the NERC Reliability Guideline on Reactive Power Planning and Operations has been posted for a 45-day industry stakeholder review. Comments must be returned to reliabilityguidelinecomments@nerc.net by August 5, 2016.
