4.0 General Description of Pioneer

Project Pioneer was designed to retrofit CCS to an operating power plant, as opposed to incorporating it into the design and construction of a new power plant. TransAlta viewed that retrofitting power plants for CCS was of much greater importance and applicability than CCS for new units, given that the majority of GHG emissions from the power sector over the next 20 years will be from existing facilities.
