ISO-NE’s wholesale electricity and capacity markets were competitive in 2017

The 2017 Annual Markets Report, issued by the Internal Market Monitor at ISO New England, concluded that the region’s wholesale power markets were competitive in 2017. The report notes that the total cost of wholesale electricity markets was $9.1 billion in 2017, which represents an increase of about 20% over 2016’s record-low costs. Energy costs made up $4.5 billion of the total, with both capacity costs and regional network load costs at $2.2 billion in 2017. The costs for reliability services such as operating reserve, regulation, and net commitment period compensation, totaled about $200 million.

Monthly wholesale electricity prices and demand in New England, March 2018

Natural gas and wholesale power prices fell in March

Milder weather during March tempered the demand for both natural gas and power and allowed the average monthly price for each to decline from the prices recorded during March 2017. The average monthly wholesale power price fell in both the day-ahead and real-time energy markets, down 1% to $35.38 per megawatt-hour (MWh)* in the day-ahead energy market and down nearly 6% to $32.87/MWh in the real-time market.

Winter 2017/2018 recap: Historic cold snap reinforces findings in Operational Fuel-Security Analysis

Weather always plays a crucial role in how ISO New England operates the region's power grid, and that was certainly the case as New England faced a historic two-week cold snap in late December and early January that sent temperatures plunging and nearly pushed the bulk power system to the brink.

"The cold temperatures, together with winter storms and other complicating factors, led to some of the most challenging conditions our system operators have ever had to navigate," said Peter Brandien, ISO New England's vice president for system operations.

Monthly wholesale electricity prices and demand in New England, February 2018

February natural gas and wholesale power prices subsided from January’s highs

Milder weather during February tempered the demand for both natural gas and power and allowed the average monthly price for each to shrink significantly from the highs recorded during January. The average monthly wholesale power price shrank more than 63% in both the day-ahead and real-time energy markets, to $39.58 per megawatt-hour (MWh)* and $36.91/MWh, respectively. While those prices marked significant declines from January’s prices, they were still up, by about 32%, from the average monthly prices recorded in February 2017.

February also marked a return to a more typical resource mix. During the extreme cold weather in early January, the spike in natural gas demand and resulting rise in prices caused coal- and oil-fired generators to be less costly to run than natural-gas-fired generators. As a result, coal- and oil-fired generators were dispatched more often in January, and generated about 15% of the energy produced by New England power plants. By contrast, in February, coal- and oil-fired power plants produced under 2% of the region’s generation. That’s closer to the usual fuel mix—in 2017, they generated just 2.3% of the energy produced in New England.

New England’s wholesale electricity prices in 2017 second-lowest since 2003

Last year’s wholesale electricity prices were the second-lowest in 15 years due to low fuel costs and relatively low consumer demand for power during most of the year. The total value of New England’s wholesale electricity market in 2017 was $4.5 billion, about 9 percent higher than 2016’s record-low $4.1 billion value in 2016, which holds the record for the lowest average annual price since 2003. The average annual wholesale power price in New England last year was $33.94 per megawatt-hour. For more information, read the press release.
