Access data and information related to voltage support in New England. See Applications and Status Changes if you’d like to do business in New England’s energy markets or need to make changes to your ISO account.
See ISO Express for a large selection of real-time and historical ISO data and reports that can help market participants make informed decisions, such as Schedule 2—VAR Annual Capacity Cost Rate Report and Schedule 2—VAR Status Summary Reports.
For electricity to continuously and reliably flow, the ISO must ensure that voltage on the transmission system is maintained within an acceptable range at all times. Voltage is regulated through reactive power dispatch, and resources on the grid may be compensated for providing this reactive power capability. VAR (voltage-ampere reactive) is the unit of measurement for reactive power.
