Monthly wholesale electricity prices and demand in New England, February 2017

Higher natural gas prices caused the average electricity price to edge up in February

The February 2017 average price of natural gas rose 6.7% year-over-year, pushing up the wholesale power price in New England by 2.4% to $28.05 per megawatt-hour (MWh)* compared to the February 2016 price of $27.39/MWh.

The 2.4% increase in wholesale power prices was smaller than the 6.7% increase in natural gas prices, in part because demand was lower in February 2017. Total energy consumption in New England declined by 7.1% in February, compared to energy usage during the previous February—but leap year was also a factor in year-over-year comparisons. Because 2016 was a leap year, February 2016 had 29 days, accounting for a portion of the higher energy consumption compared to the 28 days of February 2017.

New England’s wholesale electricity prices in 2016 lowest since 2003  

Last year’s wholesale electricity prices were the lowest in 13 years due to low natural gas prices and mild weather that dampened demand. The total value of New England’s wholesale electricity market in 2016 was $4.1 billion, $1.1 billion less than the $5.2 billion value for wholesale electricity in 2012, the previous year with the lowest market value. The average annual wholesale power price in New England last year was $28.94 per megawatt-hour. For more information, read the press release.

Monthly wholesale electricity prices and demand in New England, January 2017

January’s average price of electricity rose on higher natural gas prices

The average price of natural gas rose 14% during January 2017, pushing up the wholesale power price in New England by 8%, to $36.66 per megawatt-hour (MWh)*, from the January 2016 price of $33.99/MWh.

The smaller percentage increase in wholesale power prices compared to the natural gas increase was due to lower demand, as well as changes in the fuel mix in January. Total energy consumption in New England declined by 3% in January, compared to the previous January. Nuclear output was lower in January 2016, by about 200 gigawatt-hours (GWh) or 7.6% to 2,988 GWh, likely requiring the use of higher-priced resources. And output from low-priced wind resources was higher in January 2017, up by 48 GWh or 20% to 298 GWh, likely displacing some higher-priced resources.

Fall 2016 markets report reviews wholesale market outcomes during September, October, and November 2016 

The Fall 2016 Quarterly Markets Report prepared by the Internal Market Monitor (IMM) of ISO New England reviews wholesale energy market outcomes for September, October, and November of 2016.

The Fall 2016 Quarterly Markets Report notes that the total wholesale cost of electricity (including energy, capacity, and ancillary services) during the three-month period was $1.17 billion, down 17% compared to the market value of $1.40 billion during the fall of 2015. The average real-time wholesale energy price was $24.72 per megawatt-hour, 22% lower than the average real-time price in fall 2015. The year-over-year decline was driven by natural gas prices that averaged $2.45 per million British thermal units, 21% lower than the average price during the fall of 2015. Lower demand was also a factor; energy usage declined 3%, to 28,812 gigawatt-hours, in fall 2016 from the fall 2015 level.

Monthly wholesale electricity prices and demand in New England, December 2016

December’s average price of electricity rose on colder temperatures, higher demand, and higher natural gas prices

The average price of natural gas more than tripled during December 2016 and that, combined with higher demand for power, caused the wholesale power price in New England to rise more than twice as high as the price in December 2015.

The price of natural gas rose 226% in December, driving a 152% increase in the wholesale electricity price, to $53.83 per megawatt-hour (MWh)* from the December 2015 average price of $21.35/MWh.

December’s cold temperatures pushed up demand for power. As measured by heating degree days**, December 2016 was much colder than December 2015, and much closer to the normal level of heating degree days during a New England December. Cold weather also drives up demand for natural gas for heating, resulting in natural gas pipeline constraints that cause natural gas prices to rise.

Monthly wholesale electricity prices and demand in New England, November 2016

November’s average price of electricity fell on continuing low natural gas prices and low demand

Eight of the 10 months with the lowest wholesale power prices in 13 years occurred in 2015 and 2016, including November 2016, with the seventh-lowest monthly price. Low natural gas prices and lower demand for electricity brought November’s average monthly power price down 7%, to $24.30 per megawatt-hour (MWh)* from the November 2015 average price of $26.12/MWh. Total energy consumption in New England in November was the lowest of any November since 2000, and the sixth-lowest consumption of any month since 2000.
