PJM, NYISO Launch Market-to-Market Coordination Between Transmission Systems

PJM Interconnection and the New York Independent System Operator (NYISO) have successfully begun jointly managing transmission limits that occur near the "seams" between their regions.

The coordination between the two markets will increase the efficiency and lower the costs of electric transmission congestion management, the RTOs said.

The RTOs said that the benefits of market-to-market coordination between NYISO and PJM include:

• Lower overall congestion costs for consumers

• More consistent prices across the two wholesale electricity markets because prices at the borders between them are expected to come together more closely

• Greater reliability because a broader pool of resources is available
