Gas Study Phase II Update

12

Gas Study II Update

• Final Gas Study II report expected to be available by February 1st, 2002.– NEGA reviewing and comments outstanding.

• Study Results– New England’s gas pipeline (during coldest part of

the Winter) can not meet the coincidental demands from both LDC’s and the electric generator sector.

– On a peak day, approximately 1,350 MW of generation may be at risk.

• 3,100 MW next Winter (Ref. Case)• Possibly 3,900 MW by Winter of 2004/5 (High case)

13

Gas Study II Update, con’t.

• Study Results– During 60-day Winter average (12/15 - 2/15)

approximately 425 MW of generation may be at risk.• 1,300 MW next Winter (Ref Case)• Possibly 3,200 MW in 2004/5 (High Case)

– The loss of vaporization (Winter peak day - 2001/2002) capability of Distrigas LNG would not be expected to undermine electric grid security objectives.

• Margins are razor thin.

– ISO-NE has approximately 3 - 48 hours to respond to gas pipeline contingency events.

• Depends on location and nature of contingency.

14

Gas Study II Update, con’t.

• Recommendations– ISO New England should:

• Determine all gas-fired generator’s fuel transportation arrangements.

• Identify units that have on-site compression capability to supplement mainline pressure deviations during adverse operating events.

• Determine the back-up fuel capability of each generator including options on refill arrangements.

• Establish communication protocols directly with New England’s pipelines and LDC’s to monitor gas contingency events. This will strengthen the ISO’s ability to implement contingency plans for synchronization of replacement generation.

15

Gas Study II Update, con’t.

• Recommendations, con’t.• Participate in the Energy Industry Standard Board

(EISB) committees that will be developing electronic communications protocols, template agreements for transmissions and scheduling standards to eliminate seams issues in energy transactions between electric and gas market counterparts.

• Limit its dependency on gas-fired generation to provide operating reserve during Operational Flow Order events.

• Maintain the steady state and transient flow simulation models in order to stay abreast of rapidly changing gas market dynamics in the greater Northeast.

Summer 2002Capacity Assessment Summary

Week beginning June 22, 2002 - which has Least Operable Capacity Margin

MW

Projected Peak 24,200*

Operating Reserve Required 1,700

Total Operable Cap. Required 25,900

Projected Capacity 28,540

Assumed Outages 2,500

Total Capacity 26,040

Operable Capacity Margin 140

*Peak Loads from the preliminary 2002 CELT Report.

20

Summer 2002

June - September 2002

• Positive capacity margins are currently forecasted for the Summer Period, ranging from approximately 140 MWs to 5,070 MW.

• At this time, it is expected that there would be adequate capacity to meet expected demand. However delays in new generation expected to be online or extended heat wave could result in lower than expected positive margins.

• Total Operable Capacity Required 23,190

• Projected Capacity 28,670– Assumed Outages -2,600

• Total Capacity 26,070

• Operable Capacity Margin 2,880

• Margin (%) 33.4

Winter 2002

January - March 2002

• Positive capacity margins are forecasted for the entire Winter Period, ranging from approximately 2,820 MWs to 5,070 MW.

• Unless the region experiences an unusual event such as unexpected Fuel Supply Shortage, it is expected that there would be adequate capacity to meet expected demand.

Security Update

26

Security Update

• NERC– Security level at “Threat-level Low”– A tool, Reliability Authority, was designed for

the Control Room supervisor to send an email to all participants.

– ISO - NE utilizes a NERC web-based tool to send and receive priority messages.

– A direct “ring down” goes into effect when a message is received from the NERC hotline; messages are sent to all satellites and the New Brunswick Control Room.

27

• In development is a 3-way procedure to disseminate electric power grid, physical building and cyber threats.

• ISO NE developed a web-based tool that send messages to all master satellites, New Brunswick Control Room and Operations Manager, along with key ISO management.
