Across North American wholesale markets during December 13–19, 2025, weather-driven fundamentals remained the primary near-term influence on operational conditions and price risk. A brief cold spell led to higher peak-period prices and tighter operating conditions in the East and Texas early in the week, while conditions eased later as forecasts turned warmer and renewable supply improved in multiple regions. In the West, market commentary described late-week prices as generally softer, with California hub pricing for the upcoming weekend showing reduced peak-price pressure as supply fundamentals strengthened. In Alberta, publicly posted pool-price data during the week indicated moderate daily-average prices, supporting the overall theme that late-week conditions were less stressed than the early-week cold snap suggested.
