2007 Summer "Watch List" Issues-~ t - -
0 Southernimportedlines thatoperation
California - relies on significant amounts ofpower, transported across transmissionare heavily loaded during normal
* Greateradditionmeasure
Connecticut - tight capacity margins;of 200 megawatts of demand-reduction

Reliability Improvements Since 2006
* Southeast - more than $1.21 billion invested in transmission in2006.
* Boston - import capability boosted by 1,000 MW due to two new345 kV transmission lines from Stoughton, MA into Boston;operational in October 2006 and May 2007, respectively.
* Southwestern Connecticut - can import345 kV transmission line from Bethel toservice in October 2006.
230 MWNorwalk
more since awas put into
* Texas - reduced its transmission congestion, allowing it toreduce the number of less-efficient generating units that mustrun in tight reliability situations from seven to one.

Fuels
o.Critical to electric supply reliability. Almost 50% is natural gas-fired
• Growing gas dependence in Texas,Florida . Midwest, Northeast, & West
e Gas supply can be interrupted infavor of home heating needs
* Mid-west coal delivery improving
