New Jan. 19-22 Cold Weather Alert Issued for Western Region

85

PJM has issued a Cold Weather Alert in effect from 4 p.m. Jan. 19 until 10 a.m. Jan. 22 for the Western Region.

This comes after PJM extended its Cold Weather Advisory for the Western Region through Jan. 22.

PJM typically issues a Cold Weather Alert one to two days ahead of when significantly cold weather conditions are expected in all or parts of the region PJM serves.

PJM normally issues this alert when actual temperatures are projected to fall near or below 10 degrees Fahrenheit. However, PJM can also issue this alert if high winds are forecasted or if a portion of gas-fired units may be unavailable due to potential gas procurement issues.

The alert keeps all affected system personnel aware of the forecasted and/or actual operating status of PJM and allows them time to prepare as needed.

Alerts do not indicate that emergency actions are currently needed.

Additionally, earlier today, PJM published its updated peak load forecast, as of 12:15 p.m. Jan.17, for Jan. 18 through 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

The information above is subject to change. Load forecasts can be viewed on the PJM Now application, PJM Data Viewer (72 hours) and PJM Data Miner (7 days).
