据油气新闻9月17日消息称，TransAlta公司推出了清洁能源投资计划，其中包括将其现有的阿尔伯塔省煤炭资产转换为天然气，并提升其在可再生能源领域的领先地位。该计划的总费用预计约为20亿美元，其中包括已在建可再生能源项目的约8亿美元。
TransAlta的计划包括在2020年和2021年将其现有的阿尔伯塔省的3个热力装置转换为使用天然气，用天然气燃烧器取代现有的燃煤燃烧器。该公司还将在2023年后期至2024年后期将其两套机组转换为高效联合循环天然气机组。
清洁能源投资计划将通过今年早些时候与布鲁克菲尔德可再生能源合作伙伴子公司的战略投资、运营产生的现金以及TransAlta可再生能源公司的战略投资筹集资金。除了为该计划提供资金，该公司还承诺在未来三年通过股票回购向股东返还至多2.5亿美元，并在2020年将公司债务削减4亿美元。

$2 billion TransAlta energy investment move to include natural gas over coal
TransAlta Corporation has introduced its Clean Energy Investment Plan, which includes converting its existing Alberta coal assets to natural gas and advancing its leadership position in renewable energy. The total cost of the plan is expected to be approximately $2 billion which includes approximately $800 million of renewable energy projects already under construction.
TransAlta's plan includes converting three of its existing Alberta thermal units to gas in 2020 and 2021 by replacing existing coal burners with natural gas burners. The Company will also convert two of its units to highly efficient combined cycle natural gas units in the late 2023 to late 2024 period.
The Clean Energy Investment Plan will be funded from the cash raised earlier this year through the strategic investment with an affiliate of Brookfield Renewable Partners, cash generated from operations, and through TransAlta Renewables Inc. In addition to funding the plan, the Company remains committed to returning up to $250 million to shareholders over the next three years through share repurchases and reducing its corporate level debt by $400 million in 2020.
