CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Project-level coal details
- Coal source(s): Highvale coal mine
Background
The station consists of the following units:
- Units 1 and 2 are each 403 MW units operated and owned by TransAlta. They were commissioned in 1983.[11]
- Unit 3 is a 495 MW supercritical unit, built as a joint venture between TransAlta and Capital Power Corporation. Construction on the plant began in February 2007.[12] It came onstream in 2011. The unit cost about US$1.98 billion to build.[13][14]
In April 2017, TransAlta said it planned to convert the power station's Units 1-2 from coal-fired generation to gas-fired generation in the 2021 to 2023 timeframe, for use until the mid-2030s.[15]
In May 2019, the Pioneer Gas Pipeline, which will connect the plant to the Tidewater Midstream’s Brazeau River natural gas complex, was completed four months ahead of schedule, enabling TransAlta to begin converting Keephill's units to gas in 2020.[16] In May 2020, TransAlta's CEO Dawn Farrell confirmed on a quarterly earnings call with investors that Keephills would be converted to gas in 2021.[17]
In November 2020, TransAlta announced that the Highvale Coal Mine, which supplies coal for Keephills, would be retired in 2021. Units 1-3 would all be converted to run on gas in 2021.[18] Once converted to gas, the units are anticipated to be able to run from 2031 to 2039.[19] Unit 2 was converted to gas in July 2021.[20] The conversion of the other two units was completed in Dec. 2021.[21]
Ownership
TransAlta and Capital Power (formerly EPCOR) are equal partners in the ownership of Keephills 3, with Capital Power responsible for construction. TransAlta operates the facility.[22]
In August 2019 it was reported that Capital Power sold the 50% stake in the Keephills 3 unit to TransAlta Corporation in exchange for TransAlta's 50% share in Genesee 3 unit.[23]
Coal supply
TransAlta's Highvale coal mine supplied Keephills with coal.[24]
TransAlta pays for pro-coal research by University of Alberta
In July 2018 it was reported that TransAlta paid the University of Alberta $54,000 in 2015 to hand-pick a professor to generate pro-coal research and talking points to be used in lobbying government officials.[25]
