Examples of Voltage Reduction Warning in a sentence

  • The Local Arrangements Committee hopes to be able to offer a transportation option to Anaheim for an extra charge for those going on to ALA Annual.

  • Following the Voltage Reduction Warning, the Office of the Interconnection may issue a Voltage Reduction Action during which it directs PJM Members to initiate a voltage reduction.

  • On January 6, in response to a reserve shortage, PJM issued a Voltage Reduction Warning, followed shortly by a Voltage Reduction Action in hours 19 and 20.

  • The purpose of the Voltage Reduction Warning is to warn PJM Members that the available Synchronized Reserve may be less than the Synchronized Reserve Requirement and that a voltage reduction may be required.

  • When PJM issues a Primary Reserve Warning, Voltage Reduction Warning, or Manual Load Dump Warning, all other non-emergency, generation capacity resources must have an offer and be available for reserve.As of September 30, the MMU estimates that at least 14 percent of eligible energy resources are not in compliance with the synchronized reserve must-offer requirement.

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

  • If PJM issues a Primary Reserve Warning, Voltage Reduction Warning, or Manual Load Dump Warning, all off line non-emergency generation capacity resources available to provide energy must submit an offer for Tier 2 synchronized reserve.25 This rule ensures that IT-SCED and RT-SCED will be able to make accurate estimates of the amount of Primary Reserve available.

  • 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.

  • Under the CP construct, capacity resources have the incentive to be available when needed.If the January 7 scenario had occurred under the CP construct, PJM would have had enough resources to meet the peak load and there would not have been a Voltage Reduction Warning.

  • 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.
