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.

Draft load forecast indicates energy usage and peak demand will decline slightly over the next 10 years

ISO New England develops an annual projection of how much electricity the region will use every year for the next 10 years, as well as how high demand will peak during each of those years. The 10-year forecast is a key system planning tool, helping ensure New England has an adequate supply of resources to meet future demand and a transmission system that can do the job of carrying power to residents and businesses.

The draft long-term forecast for 2018 to 2027 projects that energy usage and peak demand will decline slightly in New England over the 10-year period. The primary factors are continuing installation of energy-efficiency measures and behind-the-meter photovoltaic (BTM PV) arrays throughout the region.
