The transaction values the equity of Horizon at USD 2,150 million. Horizon´s net financial debt as of December 31, 2006 was USD 180 million. The total cash consideration to be paid at the closing of the transaction will be adjusted for capital expenditures, which are currently estimated to amount to an additional USD 600 million.

The acquisition will be funded by debt raised at EDP and proceeds from a tax equity partner, which are both fully underwritten.

The transaction is subject to customary closing conditions, including certain federal and state regulatory approvals and clearance. The transaction is targeted to close by the end of the 2nd quarter 2007.

The acquisition of Horizon is a natural fit with EDP´s strategy, as it:

(i) Accelerates the implementation of the strategic guidelines defined in the 2007-2010 plan;
(ii) Enhances EDP´s global leadership in renewable generation;
(iii) Provides entry into the high growth US market with a leading position; and
(iv) Diversifies EDP´s income sources, reducing portfolio risk.

The combined entity resulting from the acquisition will be a leading global renewables player, with over 3,800 gross megawatts ("MW") of wind power generation in operation by the end of 2007.

Since it was founded in 1999, Horizon has been one of the most successful wind developers in the United States, largely because of its highly experienced management team. The company currently owns 559 gross MW of operating wind projects and has 997 MW of projects under construction, for expected operational capacity by the end of 2007 of 1,556 gross MW (1,324 net MW). Horizon also has a strong pipeline of projects in several stages of development in 15 different states across the country, with combined aggregate generating capacity of over 9,000 MW.

The assets of Horizon represent a high quality portfolio, namely through a presence in highly liquid and diversified energy markets, a strong footprint in the main Renewable Portfolio Standards ("RPS") states, and high wind resource sites (the average load factor for the projects in operation and under construction is 37,5%). The portfolio has been carefully reviewed by highly experienced external consultants, such as Garrad Hassan for wind and engineering, AMEC for environmental and ICF International for energy outlook.
