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, 2005 SCC Report, less recent retirements or deactivations that have not yet been reflected in the SCC Report. The Operable 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. For the month of January, a total of 2,950 MW have been delisted with 950 MW sold outside New England. It is assumed that 950 MW will be delisted through March. 4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, values for SCC, Interchange and De-listed ICAP sold are rounded to the nearest ten

and New Generation is rounded to the nearest hundred.5. Peak Load Exposure per the April 2004 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. Allowance for Unplanned Outages includes forced outages and maintenance outages scheduled less than 14 days in advance.8. Relief from certain OP 4 Actions varies, depending on system conditions. 9. Highgate maintenance scheduled.

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.

Transmission Siting Update• SWCT

– Phase I• Received conditional approval from Connecticut Siting Council 2/11/04.• ISO in receipt of “preliminary” schedule 12C application.

– Phase II• ISO, NU and UI submitted the third and final Reliability and Operating

Committee (ROC) harmonics/overvoltage report on December 20. Recommendation was for 24 miles of UG XLPE cable.

• Next hearing dates are scheduled for 1/11 and 1/13. Main topic is the ROC Report; HVdc will also be discussed.

• BOSTON– New Boston 1 needed until NSTAR completes 345 kV Reliability Project from

Stoughton to Hyde Park and K Street (2006 earliest)• Received RC recommendation for 18.4 (conditional) and 12C approval on

7/29/04.• Additional analysis of harmonics/transient overvoltage completed.• Conditions removed at 12/13/04 RC Meeting.• EFSB/DTE approval on 12/23/04.

– Salem Harbor needed at least until NGRID North Shore upgrades (2006 earliest)– These units provide operating reserves for the current system as well as insurance

for delays in transmission projects.– Long-term solution is functioning Resource Adequacy market to incent generation

to locate in the most appropriate areas, with the ability to do gap RFP’s to address timing issues.

• NWVT– State hearing process continues

• Surrebuttal hearings held late September• Decision expected by January 24
