Puget Holdings completes acquisition of Puget Energy and Puget Sound Energy
Washington utility customers see immediate benefits; Alaska Air’s Bill Ayer becomes chairman

          BELLEVUE, Wash. – Puget Holdings LLC, a group of long-term infrastructure investors, today announced the completion of its $7.4 billion merger transaction with Puget Energy and its wholly-owned utility subsidiary, Puget Sound Energy, acquiring all of the issued and outstanding common shares of Puget Energy for $30 a share.

          “Our merger with Puget Holdings is already providing benefits to our 1 million electric and nearly 750,000 natural gas customers in Western Washington,” said Stephen P. Reynolds, president and CEO of Puget Energy and PSE. “During this time of economic instability, PSE has been able to improve its credit rating and secure long-term credit facilities to improve and expand our energy delivery system, providing local jobs and meeting local needs.”

          On Jan. 16, after both Puget Holdings and Puget Sound Energy accepted the Washington Utilities and Transportation Commission merger approval order, Standard & Poor’s increased PSE’s corporate credit rating to BBB from BBB- and its secured bond rating to A- from BBB+. The ratings upgrade is expected to result in meaningful savings for PSE customers for years to come due to reduced borrowing costs.

          “At a time when most companies are only able to secure one-year bank loans, the merger also enabled PSE to enter into new credit facilities with 5-year terms,” explained Reynolds. “This is on top of the $100 million in rate credits and other savings over the next decade customers will begin receiving as early as this month and the committed access to long-term, stable capital – $1 billion a year for the next 5 years – provided by our new owners.”

          Effective with today’s completed transaction, William (Bill) S. Ayer, chairman and chief executive of Alaska Air Group, became the chairman of the boards of directors for Puget Energy

and PSE. Reynolds, who today relinquished his three-year title as chairman, remains as PSE president and CEO, continuing to serve on the Puget Energy and PSE boards. The PSE board also includes Herbert B. Simon, a member of Simon Johnson LLC, a real estate and venture capital investment company in Tacoma.

          Today’s transaction will enable PSE to continue to make significant investments in renewable resources to meet evolving green energy requirements and investments in its distribution system for natural gas and electricity customers to improve security and reliability. The transaction also includes a $5 million contribution to the Puget Sound Energy Foundation to support local community services and programs.

Rate credits:

	§		Every PSE bill over the next 10 years will include a rate credit, cumulatively totaling up to $10 million per year.
	§		The credits are expected to begin appearing on customer bills on Feb. 13, 2009.

Investments in renewable resources; expanded commitment to energy efficiency:

	§		Continued commitment to renewable resources, such as wind power, with a goal of securing 10 percent of PSE’s power supply from renewable resources by 2013.
	§		Boosted recruitment for enrollment in PSE’s voluntary Green Power Program, which is targeted to include 5 percent of electric customers by 2014.
	§		A study will identify ways to obtain energy efficiency improvements in the generation, transmission and distribution of energy.

Strengthen reliability and customer service:

	§		Planned investment of nearly $600 million in 2009 to upgrade aging natural gas pipes and electric wire and extend the utility system to new developments.
	§		Management of accurate billing to be included among the customer service performance measurements reviewed by the UTC.

Increase funding of Puget Sound Energy Foundation:

§

A $5 million contribution to the Puget Sound Energy Foundation to extend support of programs and services in the communities where PSE operates.

          On Friday, Feb. 6, Puget Energy‘s common stock traded for the last time on the NYSE and will be delisted from the exchange prior to trading hours on Monday, Feb. 9, 2009.
