"Through the tremendous efforts of the CPV and ArcLight teams, CPV Wind has been built into one of the leading wind development companies in the country. The strong management team of CPV and the successful development of the portfolio was key to our attracting the attention of the world leader in renewable energies generation and helped to facilitate this transaction." said Dan Revers, Managing Partner of ArcLight Capital.

The sale of CPV Wind to Iberdrola pairs the project portfolio with a leading owner and operator of wind generation worldwide.
