TransAlta says it will buy two natural gas power plants in Colorado from existing owners in a deal valued at about US$1 billion. The acquisition is presented as part of TransAlta’s efforts to expand its generation portfolio in the United States. Separate from the plant purchase agreement, TransAlta also announces a capital raise linked to the transaction, describing a bought deal offering with total proceeds of about US$350 million (as characterized in one report). The companies involved have not been described in detail in the provided source excerpts, and the summaries do not specify financing terms beyond the approximate offering amount, nor do they lay out timelines or regulatory steps. Overall, both reports focus on the same core points: a US$1 billion purchase of two Colorado gas assets and a roughly US$350 million bought-deal equity offering to help fund the transaction. As more details are released in full coverage, items such as expected closing dates, purchase conditions, and the plants’ capacities and operating characteristics would typically be clarified.
