Planned replacement of Cinergy Hub

In the North American electricity market, Platts is planning to replace, effective January 1, 2012, the Cinergy Hub with the Indiana Hub. Platts' planned replacement reflects the decision by the Midwest Independent Transmission System Operator to replace the existing Cinergy Hub with a new Indiana Hub on that date.

MISO is making the change because a portion of the area within the existing Cinergy Hub in MISO will become part of the PJM Interconnection when Duke Energy Ohio and Duke Energy Kentucky move from MISO to PJM effective January 1, 2012.

The existing Cinergy Hub comprises 336 nodes in the portion of the MISO electric grid covering parts of southwestern Ohio, northern Kentucky, and Indiana. MISO's new Indiana Hub comprises 186 nodes in the Duke Energy Indiana footprint that are part of the current Cinergy Hub, plus one additional node in Indiana.

MISO defined the new Indiana Hub so the pricing would be as similar as possible to the existing Cinergy Hub. Additional information and MISO studies regarding the new Indiana Hub are available at https://www.midwestiso.org/Library/MeetingMaterials/Pages/THTF.aspx. (Click on "2010" and then on "20101008" to see the price comparison study and other materials.)

PJM has decided against designating as a trading hub the portion of the existing Cinergy Hub that will move from MISO to PJM.

The Cinergy assessment is published in Megawatt Daily and Energy Trader, and on Platts Electricity Alert pages 502 and 503. It is also available with other electricity assessments via Platts Market Data services under category ES. The final assessment for the existing Cinergy Hub will be for trade date December 30, 2011, and flow date December 31, 2011.
