Winter 2016 quarterly markets report reviews wholesale market outcomes during December 2015, and January and February 2016 

The Winter 2016 Quarterly Markets Report prepared by the ISO's Internal Market Monitor concludes that during the winter season—December 2015, and January and February of 2016—market prices reflected the cost of providing energy and that New England’s wholesale energy market outcomes were competitive. The quarterly report provides information on market outcomes, system conditions, and market competitiveness.

The report notes that the total wholesale cost of electricity (including energy, capacity, and ancillary services) during the three-month winter period was $1.34 billion, down 57% compared to the market value during the 2014/2015 winter. The average real-time wholesale energy price was $27.58 per megawatt-hour, a decline of 64% compared to the previous winter. Wholesale market costs were driven down by lower natural gas prices and lower electricity demand because of milder winter weather. Natural gas prices averaged $3.35 per million British thermal units—a decrease of 68%. Average hourly demand was 14,304 megawatts (MW) in winter 2016, or 8% lower than the 15,606 MW of average hourly demand the previous winter.
