- Power demand spiked along the East Coast as winter weather blanketed the region, and real-time electricity prices responded by reaching almost $300 per MWh in some PJM zones.
- Arctic temperatures are anticipated in the next couple of days, and energy officials have called on consumers to prepare by reviewing conservation and safe heating facts.

A blast of cold weather pushed real-time prices higher in PJM Interconnection's territory yesterday, trading up to about $280/MWh in a couple of regions at one point, Platts reported.

PSE&G issued winter recommendations to its customers in New Jersey, noting that "frigid weather is here, and heating systems are working extra hard." The utility suggested customers lower thermostats by one degree to potentially reduce heating bills by up to 3%.
Pennsylvania regulators issued recommendations as well, adding that "severe cold temperatures put extra demands on utility systems, but energy conservation helps."
The National Weather Service said through the end of the week an Arctic weather pattern would "bring bitterly cold weather from the western High Plains to the Mid-Atlantic and Northeast U.S. Widespread subzero overnight lows are forecast for the Dakotas, Upper Midwest, Great Lakes, and interior New England."
NWS said there are wind chill advisories and warnings are in effect for many of these same areas, with some of the coldest wind chill readings in the -25 to -45 degree fahrenheit range. Record low temperatures are possible.
