interregional market system

New York ISO and ISO New England Streamline Energy Exchange Between Regions

The New York Independent System Operator (NYISO) and ISO New England implemented a new interregional market system that will streamline electric energy transactions and improve the flow of power between the two markets. Introduced on December 15, Coordinated Transaction Scheduling (CTS) makes more efficient use of the transmission lines by enabling market participants to access the lowest-cost source of power between the two regions.
