Examples of Voltage Reduction Warning in a sentence

  • PJM triggered a Voltage Reduction Warning the next day because of the high forced outage rates.

  • At 04:52, PJM issued a Voltage Reduction Alert.75 PJM then, at 06:17, encouraged Market Participants to submit bids to sell Emergency energy into PJM.76 At 07:15, PJM issued a Voltage Reduction Warning and Reduction of Non-Critical Plant Load.

  • PJM also describes a scenario using the operations on January 7, 2014: To expand on this, at 2:51AM on January 7, 2014 when the Voltage Reduction Warning was issued, the PJM load was 120,381MWs. The peak did not occur until four and a half hours later and was 138,733MWs. During that four and a half time period, PJM dispatchers were highly focused on scheduling resources to come online when needed and to then follow the PJM basepoints being sent every 5 minutes.

  • An Emergency Action is defined as any emergency action for locational or system-wide capacity shortages that either utilizes pre-emergency mandatory load management reductions or other emergency capacity, or initiates a more severe action including, but not limited to, a Voltage Reduction Warning, Voltage Reduction Action, Manual Load Dump Warning, or Manual Load Dump Action.

  • PJM triggered a Voltage Reduction Warning on January 7, 2014, because the reserves estimated by PJM to be available for the evening peak on January 6 did not respond when called.
