Below, affected ISO customers can learn more about changes to systems or procedures related to the Coordinated Transaction Scheduling (CTS) Project. This project was one of several that 黑料网 has undertaken, in collaboration with stakeholders, for the continued development of the region’s wholesale electricity markets.
See Participant Readiness Project Outlook for more detail on specifically affected customers and systems for this and other major projects.
Project Implemented: 12/15/15
In 2011, stakeholders for New England and New York supported an enhanced scheduling process to improve the efficiency of electricity trades between the two regions. The Coordinated Transaction Scheduling (CTS) project addressed those improvements with a design to modify the real-time external transaction submittal and scheduling process using an updated version of the New York ISO’s Joint Energy Scheduling System (JESS), along with slight modifications to ISO-NE’s Enhanced Energy Scheduling (ESS) application. Participants affected by this change included New England and New York participants engaging in external transactions at the Roseton Interface and consumers of external transactions data. Several training and sandbox sessions were held to prepare participants for the changes related to the project.
Affected market participants were required to take specific steps or adapt to changes in ISO systems, as described below.
