Beating the heat: How ISO-NE prepares for summer peak demand

As the region gears up for a season of fun in the sun, ISO New England prepares for conditions unique to the hot, humid summer months. Peak demand brought on by warmer weather and an increased reliance on energy-intensive technologies, such as air conditioning, can create complex challenges for the grid operator.

To maintain a reliable supply of electricity to New England’s residents and businesses, the ISO’s System Operations team must rely on carefully planned procedures to increase power generation and curb consumption during periods when demand for electricity threatens to exceed available capacity and reserves. High consumer demand or unplanned resource outages—when a transmission line or generator suddenly goes offline—are typically the reasons for these procedures to be enacted.

2016 summer outlook: sufficient electricity supplies expected

Some natural gas generators may need to get their fuel from other sources during pipeline construction

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 26,704 MW megawatts (MW). Extreme weather of 94°F could push up electricity demand to 29,042 MW. Construction work on the region’s natural gas pipeline infrastructure will require some power plants to obtain fuel from different sources. View the press release.

Winter 2015/2016 recap: New England power system performed well and prices remained low

Compared to winters past, the winter of 2015-2016 featured above-average temperatures and a brief cold snap in February. Many in the region have called it the “the winter that wasn’t.”

According to the National Oceanic and Atmospheric Administration (NOAA), this winter was the warmest on record in the US. The average temperature in the lower 48 states was 36.8°F, which is 4.6°F above the 20th-century average. That beats the previous record of 36.5 degrees set in the winter of 1999-2000.

ISO-NE launches new “cradle to grave” repository of power system equipment dynamics data

The new system improves the reliability and cost-effectiveness of system operations, the accuracy of power system planning, and the customer experience

On March 1, ISO New England released a new Dynamics Data Management System (DDMS) that provides owners of certain power grid equipment, such as generators, dynamic reactive power devices, HVDC facilities, and special protection systems, with an easier, more efficient way to upload and update the dynamics data they are required to submit.

ISO-NE’s research recognized internationally by INFORMS

Paper outlines innovative model for unit commitment as system uncertainty increases

A research paper by ISO New England’s Business Architecture and Technology (BAT) team was among the finalists for 2015’s prestigious Best Publication Award in Energy from the Institute for Operations Research and the Management Sciences (INFORMS). The paper, “Adaptive Robust Optimization for the Security Constrained Unit Commitment Problem,” describes the pioneering application of a powerful risk management modeling tool in the electricity industry. The paper won honorable mention (second place) out of numerous journal articles from operations researchers and professionals around the globe. Originally published in IEEE Transactions on Power Systems, the journal article is having significant influence; it’s been referenced by researchers in almost 300 other academic and industry publications so far.
