AltaLink Continues Investment in Alberta's Transmission Grid During the Second Quarter of 2012

CALGARY, ALBERTA--(Marketwire - July 27, 2012) -

NOT FOR DISSEMINATION IN THE UNITED STATES

AltaLink has invested more than $420 million into Alberta's transmission system this year, including more than $220 million during the second quarter of 2012, to improve electric system reliability and provide access to low‐cost and renewable energy sources.

"An upgraded transmission system is critical to enabling Alberta's electricity generation market," says Scott Thon, President and Chief Executive Officer. "Earlier in July we saw Albertans set a new record in summer demand for electricity. As that demand for electricity continues to grow, new transmission and a variety of generation sources will be the foundation of our province's continued economic development."

Today, AltaLink, L.P. announced comprehensive income of $25.9 million for the three months ended June 30, 2012, compared with $17.1 million for the three months ended June 30, 2011. Revenue for the second quarter was $96.7 million, compared with $84.7 million in 2011. The growth is primarily due to the increase in our investments to expand and reinforce the reliability of the transmission system.

As a partnership, AltaLink, L.P. reports its net income before income taxes; therefore its results are not directly comparable with net income reported by corporations that recognize income taxes in their financial statements.

AltaLink's full financial results and management's discussion and analysis can be found on AltaLink's website at www.altalink.ca or on SEDAR at www.sedar.com.

Headquartered in Calgary, with offices in Edmonton, Red Deer and Lethbridge, AltaLink is Alberta's largest independent transmission provider. The company is actively working with stakeholders to build new transmission projects in response to the province's growth thus ensuring the transmission system will meet Albertans' energy needs today and in the future. These projects will provide Albertans with access to clean, renewable electric energy and the lowest‐priced electricity available in the province.
