3. What Does CONVEX Do? Operate Transmission System Connecticut and Western Massachusetts ~220 substations ~198 generators ~34 345 kV lines, ~237 115 kV lines, ~12 69 kV lines, 1 138 kV cable, 1 150 kV DC cable. CONVEX is about 31% of New England load. Peak of 8,878 MW 8/2/2006 (New England peak 28,048 MW 8/3/06.) This is the short list. Briefly describe transmission system as the system between the generators and the distribution substations.This is the short list.

8. Why CONVEX? Power generation and transfer controlled by US Government Federal Energy Regulatory Commission (FERC)

They�re part of the Department of Energy. Independent Government Agency wording comes from FERC website. They�re part of the Department of Energy.

10. FERC Requirements Much Stricter Since 2003 Blackout (August) Required Formation of Electric Reliability Organization North American Electric Reliability Corporation (NERC) Here we�ll explain that the Blackout of August 2003, made the government take a closer look at how power is transferred across the United States. The Energy Policy Act of 2005 required creation of an Electric Reliability Organization.

11. NERC Self Regulatory Organization Develops and Enforces Reliability Standards They tell us how to operate. Assess Operations Can Impose Fines Largest to Date � Florida Power & Light - $25 Million NERC has been around for quite some time. They had guidelines they recommended following. With their appointment to Electric Reliability Organization, the �Shoulds� in the guidelines, became �Shalls� in their standards. This means they can fine us for non-compliance.NERC has been around for quite some time. They had guidelines they recommended following.

12. Why All The Regulations? Florida Blackout Tuesday, 2/26/2008 Relay Protection Removed From Equipment Equipment Faulted 3 Million Out of Power Give a brief explanation of the Florida event. Explain the video chart and show how the entire Eastern Interconnection is affected by the event. Link this to why Transmission is so heavily regulated by FERC and NERC.

13. NERC is broken down into interconnections. The importance being, power transfers between the interconnections is through DC lines. This is important because the DC line flows are not affected by system conditions in other areas.NERC is broken down into interconnections.
