On the ICE, day-ahead peak electricity prices have remained flat in January 2015 in ERCOT North 345 kV and SP15, with the exception of NYISO, as represented by Zone A prices. Eastern power prices rose as the temperature dropped. While ERCOT North prices have dropped from $30.27 USD/MWh at the beginning of the month to $28.24 USD/MWh on January 23, NYISO Zone F peak power rose from $41.6 USD/MWh at the beginning of the month to $76.33 USD/MWh on January 23, with prices peaking at $83.64 in the middle of the month. A sharp decrease in temperature in New York and Chicago between January 6 and January 20 could be responsible for the spike in prices compared to the other observed cities.
