WABAMUN, ALTA. — TransAlta Corporation recently announced work has finished on the first of three planned coal-to-gas (CTG) boiler conversions at its Sundance and Keephills power generation facilities near Wabamun, Alta.
“The full conversion of Sundance Unit 6 from thermal coal to natural gas is a significant landmark for TransAlta on its journey to transition off coal towards 100 per cent clean electricity,” said Dawn Farrell, president and CEO of TransAlta, in a press release. “Converting to natural gas from coal reduces our CO2 emissions by half from approximately 1.05 tonnes CO2e per MWh to approximately 0.52 tonnes CO2e per MWh in 2021, and highlights TransAlta’s commitment to meet our own, and our customers’, E2SG needs.”
TransAlta has spent $35 million on the Sundance Unit 6 boiler conversion and another $50 million for upgrades to the unit’s Distributed Control System and scheduled major maintenance.
By June this year the company intends to wrap up its second and third CTG conversions with Keephills, followed by Keephills Unit 3 by mid-December. TransAlta also plans to make significant progress on repowering its Sundance 5 unit into a highly efficient combined-cycle facility. Early next year, TransAlta aims to have its Alberta thermal fleet fuelled completely by natural gas. Once converted to gas, the units are anticipated to be able to run through to 2031 to 2039.
TransAlta projects it is on track to reduce its emissions by more than 70 per cent from 2005 levels by the end of 2022.
