ISO-NE prepared to operate grid through partial solar eclipse in August

Effects on solar-powered resources will be lesser than if total eclipse or if eclipse took place earlier in summer

New England will be under the shadow of the moon for much of the afternoon on August 21 during a partial solar eclipse. According to NASA, the eclipse will occur between approximately 1:20 p.m. and 4:00 p.m., with the peak expected at around 2:45 p.m., when about 65% of the sun will be blocked (called obscuration). If it is a sunny day, the ISO expects that output from the region’s 2,000 megawatts (MW) of solar photovoltaic (PV) systems will drop during these 2 hours and 40 minutes, but anticipates having sufficient resources available to meet the resulting rise in electricity demand.

Winter 2016/2017 recap: Power system performs well during generally mild weather

New England’s power system performed well during winter 2016/2017, though colder temperatures in December led to higher natural gas and wholesale electric prices compared to the prices seen during the record-setting warm weather of winter 2015/2016.

While January and February were milder than normal, temperatures in December 2016 averaged 32.4°F, more than 10°F colder than the previous December. Over the course of the winter New Englanders used 30,933 gigawatt hours (GWh) of electricity, slightly less than the 31,328 GWh used during the previous winter (which, as a leap year, included one extra day in February), but significantly less than the 33,709 GWh used during the much colder 2014/2015 winter, according to ISO New England data.

Register now for 2017 Supply and Demand Resource Operator Training

Instructor-led sessions on June 22 and October 19 feature a tour of the backup control room and a chance to see ISO system operators in action during a simulation; online training is also available

Supply and Demand Resource Operator Training (SROT/DROT) satisfies initial and continuing training requirements for personnel who act in the capacity of a designated entity (DE) or demand-designated entity (DDE). (See Operating Procedure No. 14.) You can choose to take SROT/DROT as an instructor-led session or as an online course. (Details follow.)

Summer 2017 outlook: sufficient electricity supplies expected

New England is expected to have the resources needed to meet consumer demand for electricity this summer, though tight supply margins could develop if forecasted peak system conditions occur. If this happens, ISO New England will take steps to manage New England’s electricity supply and demand in real time and maintain power system reliability. Under normal weather conditions of 90 degrees Fahrenheit (F), electricity resources should be sufficient to meet consumer demand this summer, with a forecasted peak of 26,482 MW megawatts (MW). Extreme weather of 94°F could push up electricity demand to 28,865 MW. View the press release.

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.
