New England power system performed well through winter 2014/2015

Now that the winter of 2014/2015 is one for the history books, this much we know is certain: no two New England winters are alike. A confluence of regional and global factors, advance planning and preparations, and delayed cold weather during winter 2014/2015 helped alleviate the operational issues and record-high prices seen during the previous winter.

Europe braces for unprecedented dip in solar generation during eclipse; US system operators take note

Updated on Friday, March 20, 2015 at 10:33AM by Registered CommenterISO New England

The March 20 eclipse will remove up to 35 GW of solar power from European grids; ISO-NE watching closely as regional PV growth continues

An historic event will unfold overseas in late March. For the first time, operators of large, synchronized electric power systems will have to manage a potentially sizeable loss of generation caused by a solar eclipse. Starting the morning of March 20 at 7:40 Coordinated Universal Time (UTC), the output from Europe’s solar photovoltaic (PV) systems will drop off—then ramp up again—as the moon blots out the sun’s light in rolling two-hour periods across the area.

SPI News: One year after shift in Day-Ahead Energy Market timeline, ISO-NE reports positive results to FERC

Just over a year ago, changes accelerating the Day-Ahead Energy Market (DAM) and Reserve Adequacy Analysis (RAA) timelines went into effect in New England. ISO New England and NEPOOL proposed the revisions in an effort to better align the timing of the region’s wholesale electricity and natural gas markets with the goal of improved reliability of the New England power grid. In an order accepting an acceleration of the timelines, the Federal Energy Regulatory Commission also directed the ISO to submit a report on the impact the changes have had on operations one year after they went into effect. On May 23, the ISO published an Informational Report finding that the modifications have incrementally improved gas-electric coordination.

Oil inventory was key in maintaining power system reliability through colder-than-normal weather during winter 2013/2014

The frigid temperatures that gripped much of the nation this winter posed operational challenges to the New England power grid, led to spikes in natural gas and wholesale electricity prices, and further highlighted issues related to resource performance and the importance of a secure fuel supply. In light of these challenges, here and across the country, the Federal Energy Regulatory Commission (FERC) hosted a Technical Conference on April 1, to hear from ISO New England, New York ISO, PJM Interconnection, Southwest Power Pool, Midcontinent ISO, California ISO, and other industry representatives about the impact of the cold weather on power system operations in different parts of the country.
