Summary of Event
• The Day-Ahead (DA) Energy Market for Monday, April 19 incorrectly modeled two transmission outages in the VT/NH area leading to incorrect results affecting NH, VT and West Central MA.
• The DA Market team detected unusual results and delayed the closing to investigate: DA Market and System Operations outage scheduling
personnel did not detect the problem in the allotted timeframe.
• Data Problems were identified the following day: Database included two specific outages modeled to
occursimultaneously due to delay in completing one of them: and,
Incorrect breaker numbers for scheduled outage at a substation.

and 2) future generation as as sum ed by ISO-NE Planning D epartm ent. Th is value is rounded to the nearest hundred.3. De-lis ted ICAP quantities are on ly known w ith c er ta inty in the c urrent m onth. This num ber is ad justed when a de listed generator is out on maintenanc e to avoid double counting.4. Net Capacity = (SC C) + (In terc hange) + (New Generation) - (D e- listed IC AP R esourc es ). In this equation, the SCC , Interchange and De- listed IC AP values are rounded to
the nearest ten and New Generation is rounded to the nearest hundred.5. Peak Load Expos ure reflec ts va lues published in the April 2004 C ELT R eport. 6. Operating Reserve Requirem ent based on the firs t contingenc y (Generator at 1160 MW ) plus 1/2 the second contingenc y (Generator at 1145 MW ).7. Allow ance for Unplanned O utages inc ludes: forced outages and m aintenance outages s cheduled less than 14 days in advance.8.
