Upcoming webinar: Energy Storage Market Participation Overview

Registration is open for the Energy Storage Market Participation Overview webinar to be held April 11, from 2:00–3:30 p.m. The session provides an overview of how energy-storage technologies can participate in New England's wholesale markets. It is geared to market participants and non-participant developers interested in adding energy-storage devices.


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.

ISO-NE joins with other electricity system operators to examine impact of emerging technologies

A report from an affiliation of independent electric grid operators concludes that the future of the North American power grid depends on effectively adding renewables to the grid, the accuracy and availability of data from “behind-the-meter” resources and coordinating these distributed energy resources at the grid operator level to preserve reliability.

The report, “Emerging Technologies: How ISOs and RTOs can create a more nimble, robust electricity system,” was published March 16, 2017 by the ISO/RTO Council (IRC), an affiliation of nine non-profit independent system operators (ISO) and regional transmission organizations, including ISO New England. Collectively, IRC members serve two-thirds of electricity consumers in the United States and more than half in Canada.

In the report, the IRC defines a number of positions regarding policies, strategic approaches, worthy goals, and critical success factors members feel will either enable or hinder them in the near future.

ISO-NE successfully tests backup control center

On March 7, 2017, ISO New England completed a successful test of the backup control center (BCC) in Connecticut, a fully-redundant control room maintained in the event that the main control center (MCC) in Massachusetts is rendered inoperable.

At least once a year, ISO New England tests several aspects of system operations at the BCC to ensure that operations can be performed seamlessly should an emergency affect the MCC. During the four-hour exercise, the region’s bulk power grid was managed from the BCC, while the MCC remained fully staffed in the event that any issues occurred. These tests, run in accordance with North American Electric Reliability Corporation (NERC) standards, exercise the functionality of the people, the processes, and the technology that serve control room operations.

ISO-NE market changes for subhourly settlements, real-time fast-start pricing and DARD pumps take effect

March 1, 2017 marked the completion of three key ISO New England projects aimed at improving pricing in the region’s wholesale electricity markets. Accurate and transparent pricing is integral to competition because it motivates and compensates market participants to make sound business decisions, including investments in resources needed to operate the power system reliably and efficiently.

The three market projects included:

  • Changing the interval at which the ISO settles the real-time energy and reserves markets from every hour to every five minutes
  • Incentivizing quick responses to dispatch instructions by improving real-time energy market pricing logic
  • Encouraging pump storage hydro-generating resources to move to economic bidding and away from self-scheduling options.
