Energy Market Analyst

The completion of TransAlta's 300 MW White Rock wind project is a testament to the company's strategic expansion within the renewable energy sector. The significance of a full contracting to Amazon aligns with broader market trends where major corporations are increasingly seeking sustainable energy solutions. Notably, the 820 MW in net operating capacity that TransAlta now holds in the US is a considerable increase, positioning the company as a more substantial player in the renewables market. The operational wind facilities and the secured pricing agreement for 80% of the production tax credits (PTCs) bolster TransAlta's revenue predictability. The PTCs are a key financial mechanism in the US that encourages investment in renewable energy by providing a per-kilowatt-hour tax credit. It's fair to expect that the guaranteed cash flow from such contracts will positively influence TransAlta's financial stability and provide a buffer against market volatility. From an investment standpoint, the expected annual adjusted EBITDA range of US$53 to US$57 million, which includes PTCs sale, is a strong indicator for potential investors regarding the project's profitability.

Renewable Energy Technologist

The deployment of Vestas wind turbines in the White Rock project illustrates TransAlta's commitment to leveraging advanced technology for efficient energy production. The chosen models, Vestas V162 and V136, are part of the newer generation of high-capacity turbines designed for optimal energy capture. The technical specifications, including impressive rotor diameters and turbine heights, suggest high energy yield potential. This technology not only improves the output but may also lower maintenance costs over time due to the reliability of newer turbine models. For investors, the adoption of such technology could signify a long-term strategy to maximize returns on investment through operational efficiency and potentially lower operating costs.

Financial Analyst

The long-term contracted revenues and increased weighted-average contract life of TransAlta's renewables portfolio to 12 years is a significant metric in assessing the company's future revenue streams. A longer contract life generally correlates to stable and predictable cash flows, enhancing the attractiveness of the company to conservative investors seeking longevity in their investments. The 10-year transfer agreement for the PTCs with an AA- rated customer further solidifies the company's financial position by locking in a reliable revenue stream. This move also demonstrates prudent risk management by securing a substantial portion of PTCs with a creditworthy counterpart while leaving room for potential upside through spot transactions or future contracts for the remaining PTCs.

CALGARY, Alberta, April 24, 2024 (GLOBE NEWSWIRE) -- TransAlta Corporation (“TransAlta” or the “Company”) (TSX: TA) (NYSE: TAC) announced today that the combined 300 MW White Rock East and White Rock West wind facilities (“White Rock”), located in Caddo County, Oklahoma, have achieved commercial operation. The White Rock wind facilities are fully contracted to Amazon Energy LLC (“Amazon”) and are currently supplying clean and affordable electricity to our customer. TransAlta’s portfolio in the US now totals 820 MW in net operating renewable energy capacity.

“We are pleased to bring into service our first clean electricity project in Oklahoma, White Rock, which is our largest wind project completed to date. White Rock was made possible through our long-term customer relationship with Amazon and its commitment to power its operations with 100 per cent renewable energy. Amazon is a global leader in procurement of renewable energy to achieve sustainability and carbon reduction objectives, and we are excited to be a trusted supplier to provide clean and affordable electricity as part of Amazon’s decarbonization pledge,” said Mr. John Kousinioris, President and Chief Executive Officer of TransAlta.

“In addition, we are also pleased to announce our first long-term contract to supply production tax credits (“PTCs”) to a taxable counterparty in the US. We have secured favourable pricing on approximately 80% of the expected generation of PTCs, which will provide another stream of contracted revenue that secures long-term cash flows from White Rock and further diversifies the contracted cash flows from our renewable portfolio. We look forward to operating this facility and delivering on our commitments to our customers. As I look ahead, we are nearing completion of our other Oklahoma wind project which will add another 200 MW facility, increasing our US portfolio to more than 1 GW, another key milestone for our company,” added Mr. Kousinioris.

White Rock comprises a total of 51 Vestas wind turbines and is the first of the Company’s two wind projects in Oklahoma to achieve commercial operations. On Feb. 22, 2024, the Company entered into a 10-year transfer agreement with an AA- rated customer for the sale of approximately 80 per cent of the expected PTCs to be generated from the White Rock wind facilities. The remaining PTCs are expected to be sold through spot transactions or contracted at a later date.
