Donna Soble Kaufman, Chair of the Board of Directors said, "The dividend is an important component of how TransAlta returns value to shareholders. This policy reflects the Board's intention to maintain a balanced approach to capital allocation and to continue to increase the dividend along with the Company's earnings growth. We believe our low to moderate risk business strategy and commitment to financial strength and flexibility will continue to provide our shareholders with sustainable returns through commodity market and credit cycles."

On Feb. 1, 2008, following a record year in 2007 in terms of comparable earnings per share and cash flow, the Company announced an 8 per cent increase to the annual dividend to $1.08 from $1.00 per share.
