Sulphur Dioxide From Sundance, Keephills and Genesee vs Sheerness and Battle River

Tonnes of sulphur dioxide (SO2). Sundance released 30,113 t in 2014, 1,084 t in 2021 and 1.2 t in 2024; Keephills 14,729 t in 2014, 5,475 t in 2021 and 3.5 t in 2024. Genesee stayed near 15,000 t a year until 2023 (14,677 t) and released 2,654 t in 2024. Sheerness and Battle River last reported SO2 in 2021 (1,919 t and 403 t). Releases to air reported each year to Environment and Climate Change Canada's National Pollutant Release Inventory (every air category summed), 2005 on, for the three power plants around Wabamun Lake (Sundance and Keephills in Parkland County; Genesee just across the North Saskatchewan in Leduc County; the Wabamun plant until it closed in 2010) and for Alberta's two other large coal plants that switched to natural gas, Sheerness near Hanna and Battle River near Forestburg. A year with no line is a year the plant reported none (below NPRI's threshold or no longer released), not a measured zero. Figures are what each operator reports.
