Today, Moody`s Investors Service announced that it upgraded Oncor Electric
Delivery Company LLC`s senior secured debt ratings two notches to Baa1 from
Baa3.

"We`re extremely pleased with Moody`s action today, as it reflects nearly two
years` worth of demonstrating Oncor`s independent governance and financial

this rating, as it should enhance our access to the financial markets, which
should ultimately benefit the consumers we serve."

investor, Energy Future Holdings Corp., in October 2007 at the time of the
merger with EFH.
