Specific changes will be made to: - the NERC / ranked ordering, - the addition of message for ICAP recall, - the exclusion of Federal contracts from ICAP transactions recalled, and - the inclusion of exports from LBMP reference bus as ICAP transactions. * Also, for a transaction with an external source, the decremental dollar will no longer be calculated. Please see Technical Bulletin #61 for more information regarding transaction curtailments. http://www.nyiso.com/services/documents/techbulletins/index.html * Changes will also be made to the MIS to remove the $20,000 bias from day ahead external transactions. * New data will be posted to the NYISO OASIS web site to enhance the presentation of real time data. The elements being added to the web site include zonal real time (5 minute) load values and zonal forecast load values. Consistent with a resolution passed by the Business Issues Committee (BIC), zones J & K will be combined. * The Shared Activation of Reserves (SAR) package on the real time system will be enhanced to accommodate support for Hydro Quebec (HQ) wheel-through transactions. * The NYISO Day-ahead Price Responsive Load Program will be implemented in both the MIS and the Billing and Accounting (BAS) systems. The Day-ahead Price Responsive Load program offers NYISO Customers the ability to supply a bid to the MIS indicating the cost at which it will reduce its demand by a specified number of MWs. The program will make use of the existing bidding and scheduling web pages and upload / download templates. However, you must register for this program. Contact your Customer Relations representative for details. Documents containing instructions with more details will be issued soon. * Other changes to the Billing & Accounting system (BAS) will incorporate changes to the Daily Advisory Statements that will provide additional columns of information on the Power Suppliers section of the advisory. Also, new CSV reports will be provided that give more detailed load information and static sub-zone definition. More information will be provided soon about a software tool to filter this new data. It will be provided for Market Participants whose automated data retrieval systems are not prepared to receive the revised Daily Advisory statement. Change #'s: SWHE-4WQLHZ; KKIR-4WQLHE; VLEE-4WQQGL; RDEY-4WTLS6; DCUK-4WRGYU If you notice any NYISO systems behave other than intended after the scheduled implementation date, please let us know immediately. It will be helpful if you refer to this notice if you communicate with us about these changes. Thank you, Customer Relations phone: 518-356-6060
