The PJM Interconnection expects to have 36% more power capacity than its forecast peak demand this winter, the independent system operator said Wednesday, but January-February packages across the grid operator's footprint nevertheless strengthened. PJM expects to have 184,926 MW of resources - generation and demand response - to meet forecast peak demand of 135,526 MW, an increase of 3.7% from last winter's peak of 130,689 MW, set on December 15, 2016, during what turned out to be a milder-thanaverage season. PJM also projected a one-in-10 chance of a winter coincident peak of 138,881 MW, which would leave a margin of more than 33%.
