Generation outages are expected to be approximately 62,000 MW through the affected period, in addition to key transmission outages both for maintenance and to allow for major transmission construction projects.
Total generating capacity within PJM is about 182,000 MW.
As of 4 p.m. Monday, forecasted electricity demand, or load, for the affected period is:
-- Monday – 103,125 MW
-- Tuesday – 112,447 MW
-- Wednesday – 112,282 MW
These numbers are subject to change and will be updated.
This alert does not require any action from customers.
Capacity Advisory
PJM also has a Capacity Advisory in place for Oct. 12–14 and issued a Maintenance Outage Recall for Oct. 14, in addition to an emergency order received by the DOE.
Issued up to five days in advance, a Capacity Advisory anticipates PJM actions such as:
-- Recalling or rescheduling of generation and/or transmission maintenance outages
-- Notifying neighboring grids to prepare for decreased imports from PJM
-- Alerting PJM Members to update their information about generator availability, fuel supply concerns, environmental constraints and more.
Emergency procedures took place as above-normal temperatures are forecast across much of the PJM region.
Maximum Generation Alert
A Maximum Generation Alert notifies transmission and generation owners, who then determine if any equipment maintenance or testing may be deferred or canceled.
By deferring such actions, units and transmission lines stay operational to serve demand.
The alert also notifies neighboring grid operators that exports from PJM may be curtailed, a procedural step that allows them to plan accordingly.
PJM issues a Maximum Generation Alert at the same time as a Load Management Alert, which gives advance notice that such action may be declared, including Pre-Emergency and Emergency Demand Response.
Demand Response programs pay customers in advance who sign up to reduce electricity use during stressed grid conditions.
Managing Planned Outages
PJM is currently in outage season. Typically, both transmission and generation facilities perform maintenance and construction from mid-September through early December, so they are fully available to serve loads during peak winter periods.
PJM has recalled or canceled transmission and generation outages to the extent possible.
This includes an October 11 recall of all active generation maintenance outage tickets in the region PJM serves effective noon on October 14.
Generation outages are expected to be approximately 62,000 MW through the affected period, in addition to key transmission outages both for maintenance and to allow for major transmission construction projects.
DOE Order
PJM also requested and received a combined emergency order, effective from Oct. 13–16, from the U.S. Department of Energy. The 202c order grants PJM operators additional flexibility to respond to changing system conditions by:
-- Providing temporary relief from environmental permit restrictions for generating units
-- Authorizing PJM to direct data centers and other Large Load customers to switch to backup generation resources, if necessary
Additional emergency procedures may be necessary pending system conditions.
