TransAlta Corporation ("TransAlta" or the "Company") (TSX: TA) (NYSE: TAC) today reported its financial results for the fourth quarter and full year ended Dec. 31, 2020.

"2020 was a pivotal year for TransAlta. Despite the challenges of dealing with a pandemic, we delivered strong financial performance and continued to execute on our Clean Energy Investment Plan. We delivered our first gas conversion, Sundance 6, to market and are on track to close our coal mine in Alberta by end of 2021. Our greenhouse gas emissions (GHG) profile for 2020 reduced an additional 4.2 million tonnes compared to 2019, all told we have achieved a 60 per cent reduction in GHG emissions since 2005 -- well beyond the expectations under the Paris Agreement. We also deployed 77 MW of net wind and energy storage and we continued to build TransAlta Renewables through the dropdowns we executed at the end of the year.," said Dawn Farrell, President and Chief Executive Officer. "The leadership team under John Kousinioris is well-positioned to deliver an even stronger year in 2021."

"I am  pleased to announce that TransAlta has adopted the goal of achieving carbon neutrality by 2050. We are well into our emissions reduction journey as a company and we feel our clean electricity strategy is well aligned with a longer-term carbon neutral goal. Setting this goal provides a meaningful internal signal to our team as we execute our growth strategy but provides flexibility over the coming decades.  Adopting this goal also sends a signal to our external stakeholders, including governments, regarding our intention to contribute to broader national and global efforts to meet national emissions reduction goals for 2050," said John Kousinioris, Chief Operating Officer.

Below are additional highlights from the quarter on how TransAlta is advancing its Clean Energy Investment Plan, how the Company is managing COVID-19, as well as details regarding the Company's liquidity and financial position and its objectives for 2021.

Significant Events and Other Updates

Clean Energy Investment Plan

Conversion to Gas
TransAlta's Clean Energy Investment Plan includes converting three of our existing Alberta thermal units to gas during 2021 by replacing existing coal burners with natural gas burners. The cost to convert each of TransAlta's wholly-owned units is expected to be approximately $35 million per unit. On Feb. 1, 2021, we announced the completion of the conversion to gas of Sundance Unit 6. The Company continues to advance conversion of its Keephills Unit 2 and Keephills Unit 3 for completion later in 2021 and has issued Full Notice to Proceed for both units. In addition, on Apr. 4, 2020, the dual-fuel conversion of Sheerness Unit 2 was completed. The Sheerness Unit 1 conversion to gas is in progress with expected completion in the first quarter of 2021. The Sheerness facility will discontinue firing coal by the end of 2021. The elimination of coal as a fuel source will reduce future fuel costs and GHG costs at Sheerness.

Sundance 5 Repowering
During the fourth quarter of 2020, an equipment supply agreement was executed to repower Sundance Unit 5 into a highly efficient combined-cycle unit. Commercial operation date is anticipated in the fourth quarter of 2023. The Sundance 5 repowered combined-cycle unit will have capacity of approximately 730 MW and is expected to cost between $800 million to $825 million, well below a greenfield combined-cycle project. The project has a long-term PPA for capacity plus energy, including the passthrough of GHG costs, starting in late 2023 with Shell Energy North America (Canada), for a portion of the plant capacity. The Company continues to evaluate the prospect for repowering Keephills Unit 1 in 2021 and 2022 as a potential supply addition to the Alberta market in the 2026 to 2030 timeframe.

Windrise
Construction activities continue to advance with all the appropriate procedures in place to protect the construction team during COVID-19 pandemic. The commercial operation date is expected to occur during the second half of 2021. As at Dec. 31, 2020, the project was 78 per cent complete.

Skookumchuck
On Nov. 25, 2020, TransAlta completed the acquisition of a 49 per cent equity interest in the Skookumchuck wind project ("Skookumchuck") with Southern Power Company, a subsidiary of Southern Company. Skookumchuck is a 136.8 MW wind project located in Lewis and Thurston counties near Centralia in Washington state and consists of 38 Vestas V136 wind turbines. The project began commercial operation on Nov. 7, 2020, and has a 20-year power purchase agreement with Puget Sound Energy. TransAlta's total net capital investment was $86 million (US$66 million) in cash, with an additional $77 million (US$59 million) being funded with tax equity financing.

BHP Nickel West Contract Extension
Effective Dec. 1, 2020, Southern Cross Energy ("SCE"), a subsidiary of the Company, and BHP replaced and extended its current PPA, set to expire Dec. 31, 2023, to Dec. 31, 2038. The PPA provides SCE with the exclusive right to supply thermal and electrical energy for BHP's mining operations located in the Goldfields region of Western Australia. The extension will provide SCE a return on new capital investments, which will be required to support BHP's future power requirements and recently announced emission reduction targets. The amendments within the PPA also provide BHP participation rights in integrating renewable electricity generation, including solar and wind, with energy storage technologies, subject to the satisfaction of certain conditions. Evaluation of renewable energy supply and carbon emissions reduction initiatives under the extended PPA with SCE are underway, including an 18.5 MW solar photovoltaic facility supported by a battery energy storage system and a waste heat steam turbine system.

Liquidity and Financial Position
The Company presently has access to $2.1 billion in liquidity, including $703 million in cash. During 2020, we closed an AU$800 million TEC Offering and also received the second and final tranche of the $750 million of strategic financing from Brookfield. We repaid a $400 million medium-term note due on Nov. 25, 2020. Following the closings of the recently announced drop-down transaction to TransAlta Renewables, the Company will have achieved its target of $1.2 billion of senior corporate debt.

Achieved A- Score from CDP
In 2020, TransAlta improved its scoring on the CDP Climate Change investor request. Our overall score was an A-, indicating that we are implementing current best practices. This ranks the Corporation among industry leaders on climate change management and places us as ahead of most companies in North America. The average CDP score for our peers was a B and the average score for reporting companies in North America was a D.

COVID-19
In November 2020, as a result of rising COVID-19 case counts in the Province of Alberta and in light of office attendance restrictions eventually imposed by the Government of Alberta, staff at TransAlta's head office returned to remote work protocols. All of TransAlta's offices and sites follow strict health screening and social distancing protocols with personal protective equipment readily available and in use. Further, TransAlta maintains travel bans aligned to local jurisdictional guidance, enhanced cleaning procedures, revised work schedules, contingent work teams and the reorganization of processes and procedures to limit contact with other employees and contractors on-site.

While our 2020 results have been impacted by price and demand weakness as a result of COVID-19, all of our facilities continue to remain fully operational and capable of meeting our customers' needs. The Company continues to work and serve all of our customers and counterparties under the terms of their contracts. We have not experienced interruptions to service requirements. Electricity and steam supply continue to remain a critical service requirement to all of our customers and have been deemed an essential service in our jurisdictions.

Full-Year 2020 Financial Results Summary

Comparable EBITDA^(1,3) for the full year ended Dec. 31, 2020, was $927 million, a decrease of  $57 million compared to 2019. After adjusting for the one-time PPA Termination Payment of $56 million that was received in 2019 from the Balancing Pool, and the AESO line loss adjustment of $8 million, comparable EBITDA increased by $7 million compared to 2019. Comparable EBITDA increases were driven by the Wind and Solar segment with the addition of the Big Level, Antrim and Skookumchuck wind facilities and strong wind resource across all regions, the Centralia segment due to increased benefits from dispatch optimization and recovery from a significant loss that was incurred in March 2019 from an isolated and extreme pricing event due to an unplanned forced outage, and a consecutive year of exceptional performance from the Energy Marketing segment in both power and natural gas markets. These gains were offset by a significant comparable EBITDA decline in the Alberta Thermal segment. Alberta Thermal production declines were the key contributor due to higher curtailments and dispatch optimization as a consequence of reduced industrial demand in the province and the impact of COVID-19 on demand generally.

Funds from operations ("FFO")^(1,3) decreased two per cent to $685 million for the full year compared to $701 million in 2019 excluding PPA Termination Payments. Higher interest expense from the additional tranche of Brookfield financing and the TEC Offering financing was partially offset by realized foreign exchange gains and reduced decommissioning activities resulting from COVID-19.

FCF⁽¹⁾ for the full year ended Dec. 31, 2020, was $358 million, a decrease of $77 million compared to $435 million for 2019. After adjusting for the one-time PPA Termination Payment of $56 million that was received in 2019 from the Balancing Pool, FCF decreased by $21 million from $379 million or five per cent compared to 2019. This was mostly driven by the FFO changes noted above along with higher sustaining capital expenditures from planned outages and final lease payments made on our mining equipment, along with lower distributions to non-controlling interests.

Net loss attributable to common shareholders for 2020 was $336 million compared to earnings of $52 million in 2019. Net loss attributable to common shareholders has been impacted by higher interest expense associated with the TEC Offering and the second tranche of the Brookfield Investment, higher depreciation from acceleration of the conversion to gas, gains recognized on the Keephills 3 and Genesee 3 asset swap that occurred in 2019, the one-time PPA Termination Payment of $56 million in 2019 and further impacts related to our decisions to accelerate our transition to gas, including:

• Higher depreciation as we accelerate the closure of the Highvale mine;
• Writedown of $37 million of coal inventory;
• Onerous provision of $29 million on the coal supply contract for Sheerness; and
• Impairment of $70 million associated with the retirement of Sundance 3.

Fourth Quarter Financial Results Summary

Comparable EBITDA⁽¹⁾ for the three months ended Dec. 31, 2020 was $234 million, a decrease of $9 million compared to the same period in 2019. Comparable EBITDA decrease was mainly driven by non-recurring items mostly impacting the Wind and Solar segment which include the additional AESO line loss provisions recognized in 2020 and insurance recoveries relating to tower fires received in 2019. The declines were also contributed by the Alberta Thermal segment mainly due to lower production driven by higher planned and unplanned outages and increased fuel cost resulting from the acceleration of the Highvale mine closing. These declines were offset by growth in the Wind & Solar with the additions of Big Level, Antrim and Skookumchuck wind facilities, and strong resource production in all regions along with growth in the North American Gas segments with the addition of the Ada cogeneration facility.

FFO⁽¹⁾ for the three months ended Dec. 31, 2020, decreased by 15 per cent to $161 million. Higher interest expense from the additional tranche of Brookfield and the TEC Offering financings, and higher non-cash items were partially offset by reduced decommissioning activities resulting from COVID-19.

FCF⁽¹⁾ for the three months ended Dec. 31, 2020, was $52 million compared to $121 million for 2019. In addition to the reductions in FFO noted above, the remaining changes in FCF was driven by higher sustaining capital in quarter from the Sundance 6 planned outage, final settlement of lease payments at Highvale mine and timing of distributions to non-controlling interest partners.

Net loss attributable to common shareholders in the fourth quarter of 2020 was $167 million compared to net earnings of $66 million in the same period of 2019, a decrease of $233 million. The net loss in 2020 was impacted by lower availability, which reduced revenues, the additional coal inventory writedowns of $15 million from an increased cost of coal and higher depreciation from the acceleration of the Highvale mine closure of $8 million, the onerous contract provision recognized on the coal contract for Sheerness for $29 million and higher interest expense associated with the TEC Offering and the second tranche of the Brookfield Investment, partially offset by lower asset impairments. The prior year benefited from the gain on the termination of the Keephills 3 coal rights contract of $88 million and the gain on the sale of Genesee 3 of $77 million.

2021 Outlook

The Company announced its 2021 outlook with comparable EBITDA estimated to be between $960 to $1,080 million. The midpoint of the range represents a 10 per cent increase over 2020 results. The Company expects comparable EBITDA to increase due to a number of factors.

• We expect power to be offered, dispatched and optimized in a more commercial manner in Alberta with power prices more in line with longer-term historical averages with the expiry of the remaining Alberta power purchase arrangements (the "Alberta PPAs") at certain thermal facilities and transfer of dispatch control away from the Balancing Pool and to the asset owners. Power prices are also expected to be influenced by higher carbon compliance costs and expected demand recovery relative to the economy-wide closures from COVID-19 during most of 2020.
• Expiry of the Alberta PPAs at our Hydro facilities will step-up comparable EBITDA driven by the removal of previous PPA obligation payments (net of capacity payments).
• Full year contribution of the Skookumchuck wind facility and Ada cogeneration facility.
• Windrise reaches commercial operations during the second half of 2021.

The Company expects sustaining capital to be in the elevated range of $175 million to $210 million, an increase to 2020 levels. This is driven by a considerable number of planned outages in 2021, namely the three outages in the Alberta Thermal fleet ($65 million to $75 million) to undertake the conversions to gas and other turnaround maintenance. The Company presently has Sheerness 1 on outage (carried out by our partner), and Keephills 2 outage is scheduled for an outage in mid-March, and the Keephills 3 outage is planned for mid-September. Both Keephills 2 and Keephills 3 outages are each estimated to take approximately 56 days.

FCF is expected to be between $340 million and $440 million. The midpoint of the range represents a 9 per cent increase over 2020 results.

Total Comparable EBITDA^(1,3)	234	243	927	928

• Hydro: Comparable EBITDA for the year ended Dec. 31, 2020 decreased by $5 million compared to 2019 driven by lower revenues driven by lower realized energy and ancillary prices in the Alberta market which were partially offset by higher water resources and a favourable out-of-period transmission line loss recovery.
• Wind and Solar: Comparable EBITDA for the year ended Dec. 31, 2020, increased by $17 million compared to 2019, primarily due to the full-year addition of the Big Level and Antrim wind facilities and higher production from strong wind resource across all regions, in particular Alberta. This was partially offset by an unfavourable out-of-period transmission line loss settlement of $8 million from the AESO in our Alberta fleet, insurance proceeds that were received in 2019 of $10 million for tower fires, and planned expiry of certain government power production incentives.
• North American Gas: Comparable EBITDA for the year ended Dec. 31, 2020 decreased by $3 million compared to 2019 mainly due to lower earnings at Fort Saskatchewan as the new commercial agreement was negatively impacted by lower merchant pricing in Alberta partially offset by the addition of the Ada cogeneration facility.
• Australian Gas: Comparable EBITDA for the year ended Dec. 31, 2020 increased by $6 million compared to 2019, due to the deferral of legal costs associated with a contract dispute, reduced staffing due to cost controls and the strengthening of the Australian dollar against the Canadian dollar.
• Alberta Thermal: Excluding the PPA Termination Payments, comparable EBITDA for the year ended Dec. 31, 2020 decreased $101 million compared to 2019. This largely reflects declines in gross margin from reduced production due to curtailments and dispatch optimization resulting from reduced industrial demand in the province and the impact of COVID-19 on demand generally.
• Centralia: Comparable EBITDA for the year ended Dec. 31, 2020, increased by $66 million compared to 2019, primarily due to increased benefits from dispatch optimization and a strengthened US dollar relative to the Canadian dollar and as a result from an isolated and extreme pricing event in March 2019 when Centralia was unable to commit one of its units to physical production for day-ahead supply due to an unplanned forced outage repair.
• Energy Marketing: Comparable EBITDA for the year ended Dec. 31, 2020 increased by $24 million compared to 2019 results. Results were primarily from continued strong performance in both power and natural gas markets. Gains were realized from short-term strategies across various geographic regions aided by market and price volatility. The Energy Marketing team was able to capitalize on short-term arbitrage opportunities in the markets in which we trade without materially changing the risk profile of the business unit. OM&A spending for 2020 and 2019 was similar.
• Corporate: Our Corporate overhead costs for the year ended 2020 were $81 million, compared to $76 million in 2019, with the increase primarily due to realized gains and losses from the total return swap. A portion of the settlement cost of our employee share-based payment plans is fixed by entering into total return swaps, which are cash settled every quarter. Excluding the impact of the total return swap, Corporate overhead costs for 2020 decreased by $10 million compared to 2019, mainly due to lower legal fees and lower labour and reduced travel costs, partially offset by additional costs to support growth and development projects, centralization of shared services to the Corporate segment and additional costs incurred to support COVID-19 protocols.
