Alliant Energy Begins Process To Sell Alliant Energy New Zealand Limited

Alliant Energy Corp. announced it has commenced a process to sell its interest in Alliant Energy New Zealand Limited (AENZ). AENZ, an indirectly wholly owned subsidiary of Alliant Energy Corp., holds interests in two publicly traded New Zealand companies. AENZ owns a 23.77 percent interest in TrustPower Limited, (TrustPower) New Zealand's fourth largest electricity retailer, and a 5.07 percent interest in Infratil Limited, an investor in infrastructure and utility assets.

"As we have previously stated, an international presence is no longer consistent with Alliant Energy's long-term business strategy," said John Peterson, President of Alliant International. "TrustPower has been a great investment for the company and we look forward to working constructively with TrustPower and our partners at Infratil over the course of our sale process."

Alliant Energy has appointed First New Zealand Capital, in affiliation with Credit Suisse, to manage the sale by soliciting trade buyers. ABN Amro has been given the right to investigate capital market participation in the trade sale process.
