High Quality Content by WIKIPEDIA articles! The Richard L. Hearn Generating Station (named after Richard Lankaster Hearn) is a decommissioned electrical generating station in Toronto. The plant was originally fired by coal, but later converted to burn natural gas. It is still owned by Ontario Power Generation, a publicly owned electrical generation company. The plant has been described as "Pharaonic in scale", and encompasses 650 thousand cubic metres of space—large enough to fit 12 Parthenons inside.
