PJM has extended the Cold Weather Advisory for its Western Region through Monday, Jan. 22.

Additionally PJM is providing its updated peak load forecast for Thursday, Jan. 18, through Monday, Jan. 22:

  • Thursday, Jan. 18 – 126,600 MW
  • Friday, Jan. 19 – 122,200 MW
  • Saturday, Jan. 20 – 118,300 MW
  • Sunday, Jan. 21 – 115,300 MW
  • Monday, Jan. 22 – 122,300 MW

Data as of 12:15 p.m. Eastern on Jan. 17.

Load forecasts can be viewed on the PJM Now application, PJM Data Viewer (72 hours) and PJM Data Miner (7 days).

When PJM expects significantly cold weather to impact all or parts of the PJM footprint, it issues a Cold Weather Advisory to provide a two-to-five-day notice that forecast temperatures may call for a Cold Weather Alert. This is meant to give generation owners ample time to proactively prepare their units to operate during pending cold weather and to provide information to PJM about their operating availability, capabilities and limitations to help PJM operators plan for the extreme weather.

See more information on PJM’s Emergency Procedures and Messages fact sheet.

The Cold Weather Alert that began Jan. 14 remains in effect through Jan. 17 for the same area. Additionally, in light of the weather and pipeline fuel restrictions reported by gas pipeline operators, PJM remains in Conservative Operations through Jan. 17.

Original Story (Jan. 16): PJM Extends Cold Weather Advisory Through Jan. 21 for Western Region

PJM has extended a Cold Weather Advisory for its Western Region through Sunday, Jan. 21, as temperatures are expected to remain frigid in that region.

When PJM expects significantly cold weather to impact all or parts of the PJM footprint, it issues a Cold Weather Advisory to provide a two-to-five-day notice that forecast temperatures may call for a Cold Weather Alert. This is meant to give generation owners ample time to proactively prepare their units to operate during pending cold weather and to provide information to PJM about their operating availability, capabilities and limitations to help PJM operators plan for the extreme weather.

Temperatures are expected to remain the single digits in PJM’s Western Region, which will drive up the demand for electricity in that area.

The Cold Weather Alert that began Jan. 14 remains in effect through Jan. 17 for the same area. Additionally, in light of the weather and pipeline fuel restrictions reported by gas pipeline operators, PJM remains in Conservative Operations through Jan. 17.

PJM was able to support neighboring regions through the holiday weekend with approximately 6,000 MW to 10,000 MW of net exported electricity, and those exports continue. Although information is preliminary, natural gas supply and transportation sectors have performed as expected, meaning any gas generation outages are within what is expected and planned for in frigid temperatures.

PJM will continue to monitor the progression of the cold weather eastward and determine whether additional Cold Weather Alerts are appropriate.

PJM and its member companies continue to maintain sufficient generation supply to meet electricity demand in the frigid weather.
