The regional grid operator PJM has warned that Maryland and surrounding states could see record-high electricity demand this week due to extreme cold weather, heightening concerns about the potential for temporary power outages to protect grid stability. The Maryland Energy Administration said there is a "low but not insignificant" risk of a grid event during high-demand morning hours through Friday, which could trigger load shedding. Utility officials said they are coordinating to maintain service, but have urged residents to take voluntary steps to reduce energy use during the cold snap.

Why it matters

Maryland's power grid is considered transmission-constrained, making it harder to move power into the area during periods of peak use. Extreme cold weather can put significant strain on the grid, raising the risk of temporary outages that could disrupt critical infrastructure and daily life for residents.

The details

PJM, the regional grid operator, has warned it could set a winter electricity demand record this week as extreme cold grips Maryland and surrounding states. The Maryland Energy Administration said electricity demand is elevated across PJM's 13-state footprint, but conditions are most acute in the BGE service area. Officials said there is a "low but not insignificant" risk of a grid event during high-demand morning hours through Friday, which could trigger temporary power outages to protect grid stability. Utility companies said they are in regular contact and coordinating to keep the power grid stable, but have urged residents to take voluntary steps to reduce energy use, such as lowering thermostats, postponing energy-intensive activities, and turning off unused lights and appliances.

  • This week, PJM is forecasting the potential for record peak load during extreme cold.
  • Through Friday, there is a "low but not insignificant" risk of a grid event during high-demand morning hours.

What they’re saying

“PJM is forecasting the potential for record peak load this week during extreme cold, which will stress an already constrained transmission grid and require electricity supply from all available generating facilities.”

— BGE officials

“There is a "low but not insignificant" risk of a grid event during high-demand morning hours through Friday.”

— MEA officials

What’s next

Counties were encouraged to consider closing nonessential public buildings if grid conditions deteriorate further.

The takeaway

This situation highlights the vulnerability of Maryland's power grid to extreme weather events, underscoring the need for continued investment in grid modernization and resilience to ensure reliable electricity service for residents and businesses, even during periods of peak demand and severe cold.
