Operations Highlights

• Boston & Hartford Weather Pattern: – The first half of December was very cold and snowy; the rest of the

month was above normal without snow.• Peak load of 20,698 MW at 18:00 hours on December 15.• During December:

– OP #4 declared on December 5 – system wide. Loss of multiple units within a 1-hour timeframe of the peak hour.

– M/S2 declared on December 2 (computer virus), December 5 (capacity deficiency), December 24 (System wide – ICCP link failure).

– Minimum Generation declared on December 10, 23, 24 and 25.– NPCC Shared Activation of Reserves Events on December 4,

December 5 (2) and December 7.

This analysis is a tabulation of weekly assessments shown in one single table. The information shows the operable capacity situation under assumed conditions for each week. It is not expected that the system peak will occur every week during June, July and August.

ISO-NE WINTER 2004 OPERABLE CAPACITY ANALYSISJanuary 5, 2004 - WITH KNOWN EXTERNAL CONTRACTS - 50/50 FORECAST

Notes: Please note that the information contained within the Capacity Analysis is a deterministic projection of system conditions which could materialize during any given week of the year.1. Installed Capability per January 1, 2004 SCC Report. The Installed Capability does not reflect possible transmission constraints within the NEPOOL system.2. New Generation information includes 1) generation recently commercial but not yet reflected in the NEPOOL SCC Report totals used in the Installed Capability Column, and

2) future generation as assumed by ISO-NE Planning Department. This value is rounded to the nearest hundred.3. De-listed ICAP quantities are only known with certainty in the current month.4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, the SCC, Interchange and De-listed ICAP values are rounded to

the nearest ten and New Generation is rounded to the nearest hundred.5. Peak Load Exposure per the April 2003 CELT Report. 6. Operating Reserve Requirement based on the first contingency (Generator at 1160 MW) plus 1/2 the second contingency (Generator at 1145 MW).7. Highgate maintenance scheduled.8. Allowance for Unplanned Outages includes: forced outages and maintenance outages scheduled less than 14 days in advance.9. Relief from certain OP 4 Actions varies, depending on system conditions.

1. Installed Capability per January 1, 2004 SCC Report. The Installed Capability does not reflect possible transmission constraints within the NEPOOL system.2. New Generation information includes 1) generation recently commercial but not yet reflected in the NEPOOL SCC Report totals used in the Installed Capability Column,

and 2) future generation as assumed by ISO-NE Planning Department. This value is rounded to the nearest hundred.3. De-listed ICAP quantities are only known with certainty in the current month.4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, the SCC, Interchange and De-listed ICAP values are rounded

to the nearest ten and New Generation is rounded to the nearest hundred.5. Peak Load Exposure per the April 2003 CELT Report. 6. Operating Reserve Requirement based on the first contingency (Generator at 1160 MW) plus 1/2 the second contingency (Generator at 1145 MW).7. Highgate maintenance scheduled.8. Allowance for Unplanned Outages includes: forced outages and maintenance outages scheduled less than 14 days in advance.9. Relief from certain OP 4 Actions varies, depending on system conditions.

This analysis is a tabulation of weekly assessments shown in one single table. The information shows the operable capacity situation under assumed conditions for each week. It is not expected that the system peak will occur every week during June, July and August.
