ISO-NE incorporates wind-powered resources into real-time dispatch with Do Not Exceed Dispatch Project

The change helps improve price formation in the markets and marks an important milestone in ISO New England’s efforts to efficiently integrate renewable resources

On May 25, the region’s wind-powered resources and intermittent hydro resources began taking electronic dispatch instructions from ISO New England for the first time and became eligible to set real-time prices in the wholesale electricity marketplace. These changes were effected by the Do Not Exceed (DNE) Dispatch Project in which the ISO worked with stakeholders to implement a modified electronic dispatch method for these intermittent resources. The new system is expected to improve price formation in the marketplace and system use of low-cost renewable resources in areas with limited transmission capacity by:

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.
