New flexibility added to Enhanced Energy Scheduling (EES) application

In response to market participant feedback, ISO New England is enhancing the functionality of its Enhanced Energy Scheduling (EES) application, which is used to submit external transactions in the energy markets. Currently the EES only allows participants to submit one price per transaction in the Day-Ahead Energy Market, meaning participants with varying hourly prices must submit unique transactions for each individual hour. Beginning September 1, 2018, participants will be able to submit day-ahead external transactions with prices that vary by hour, consistent with the functionality available for the Real-Time Energy Market. The sandbox environment incorporating this change will be available to users on August 13, 2018.

Update on ISO-NE’s operational fuel security initiatives

Market changes are fast-tracked to address serious challenges

Soon after releasing its Operational Fuel-Security Analysis (OFSA) in January 2018, the ISO began meeting with stakeholders to discuss the results and developing plans to address the region’s fuel security risks in the short- and long-term. However within a few months of issuing the analysis, Exelon Generation announced that it intended to retire its Mystic Station generating units effective May 31, 2022. These units and their fuel source, a neighboring liquefied natural gas (LNG) import terminal, were explicitly identified in the OFSA as critical to the region’s fuel security. Given the increased urgency of the region’s fuel-security challenges, the ISO accelerated efforts already underway to address these risks.

Heat wave recap: Reliable operations through holiday heat & humidity

Power system operates smoothly during the June 29-July 5 heat wave

Fireworks weren’t the only things ablaze during the Independence Day holiday week–temperatures surged throughout New England as well, causing high demand for air conditioning and, consequently, the electricity that powers it.

Despite the unusually hot, humid conditions during the June 29–July 5 heat wave, the timing of the holiday, coastal breezes, and abundant solar power kept electricity demand in check. With a peak of around 24,000 megawatts (MW), ISO New England’s system operators were able to rely on a high-performing fleet of resources to keep the grid running smoothly and reliably throughout the heat wave.
