SUBSCRIBER NOTE: Into Entergy index unaffected by MISO expansion

In North American electricity, Platts will continue to publish the Into Entergy bilateral day-ahead electricity index based on the existing location description following the expansion of the Midcontinent Independent System Operator to include the Entergy utility footprint in Arkansas, Louisiana, Mississippi and Texas. The existing Into Entergy bilateral day-ahead index comprises bilateral transactions that result in power delivered to an interface with or a delivery point within the Entergy utility footprint, which spans portions of Arkansas, Mississippi, Louisiana and Texas; the index does not include power delivered into any other entity's system for which Entergy acts as a balancing authority. The Entergy utility footprint will be integrated into MISO effective trade date December 18 for flow date December 19. Other entities that will become part of MISO at that time are Cleco, Lafayette (Louisiana) Utilities System, Louisiana Energy and Power Authority, Louisiana Generating and South Mississippi Electric Power Association. MISO has defined three locational marginal price (LMP) hubs--MISO Texas, MISO Arkansas and MISO Louisiana--that will go into effect with the MISO expansion. The existing Into Entergy index includes those areas, and day-ahead bilateral transactions that occur at those MISO LMP hubs beginning trade date December 18 will be included in the Into Entergy Index. The LMP prices for MISO Texas, MISO Arkansas and MISO Louisiana will be added in a table on page 5 of Megawatt Daily beginning December 19, and will be also be added to Platts Market Data category IK. Related marginal heat rate data will be added to Platts Market Data category IL. For questions, please contact Mike Wilczek at mike.wilczek@platts.com.
