PROVIDES ACCESS TO TIDEWATER STORAGE FACILITIES

Alberta Pipeline Strategy

NATURAL GAS PIPELINE REQUIREMENTS

 Sundance and Keephills can consume up

to 175 MMcf/d through fuel blending; up to 700 MMcf/d once converted

 Existing pipelines can provide only limited

amount of gas today

 Two or more pipelines will be secured in

  • rder to minimize the risk of any supply

disruptions and to provide diversified access to natural gas in Western Canada TIDEWATER NATURAL GAS PIPELINE

 Entered into Letter of Intent with

Tidewater to construct a 120 km pipeline from their Brazeau River Complex to TransAlta’s generating facilities

 Initial volumes of 130 MMcf/d with the

potential to expand to 340 MMcf/d

 Cost of ~$150 million, and expected COD

in early 2020

 TransAlta has the option to invest in up to

50% of the pipeline

 Aligns both companies interests;

provides low cost access to natural gas transportation and future flexibility

 Ownership builds on TransAlta’s
