PJM extends capacity advisory to October 14; DOE grants limited emergency authority

PJM recalls maintenance outages during warm fall conditions. DOE Order 202-26-50 applies October 13-16 and limits backup generation to emergency reliability use, not routine operation.

PJM extended its Capacity Advisory to Wednesday, October 14, according to the grid operator's October 12 announcement. PJM linked the expected tight conditions to relatively warm fall weather and equipment outages for maintenance and construction. An advisory anticipates possible operating actions; it is not a report that customer power has been cut.

The operator says it has recalled or canceled transmission and generation outages where possible. An October 11 recall covers active generation maintenance outage tickets until noon on October 14. PJM expected approximately 60,000 megawatts of generation outages on Monday, in addition to key transmission outages. That is a dated outage forecast, not a measure of unmet household demand.

PJM explains that autumn is normally an outage season, with maintenance and construction from mid-September through early December to prepare equipment for winter peaks. The advisory can also prompt neighboring grids to prepare for decreased imports from PJM and members to update generator availability, fuel supply and environmental-constraint information.

The Department of Energy separately confirms that it issued Order No. 202-26-50 on October 12 under section 202(c) of the Federal Power Act, following PJM's October 11 application. The order is effective October 13 through October 16. This is granted authority, not merely a pending request, as an earlier version of the PJM announcement described it.

DOE says the order directs PJM to dispatch specified units as needed for reliability. It also authorizes backup generation as a last resort before declaring an Energy Emergency Alert 3 or during such an alert. PJM can call on transmission owners and electric distribution companies to implement the order. The emergency condition matters: this is not blanket permission for routine backup-generator operation.

The advisory and temporary order address operating flexibility during forecast tight conditions. They do not establish that a blackout has occurred or quantify a household electricity-bill change. PJM says forecasts can change and additional emergency procedures may become necessary as system conditions develop.
