TransAlta has transformed itself from one of Canada's largest electric utilities into a global independent power producer with assets in Australia, Canada, and the US. The company has about about 8,950 MW of net operational generating capacity. It trades and markets electricity and gas in Canada and the US. Most of TransAlta's generating capacity is coal-fired; the rest comes from gas-fired, hydroelectric, and alternative-energy plants. TransAlta has sold its regulated distribution and transmission businesses to focus on power generation and marketing, primarily to industrial and wholesale customers. The company has power plants in Australia (5), Canada (55), and the US (17).
