TransAlta Corporation (TransAlta or the Company) (TSX: TA) (NYSE: TAC) today reported its financial results for the quarter ended Sept. 30, 2020.

“TransAlta’s third quarter delivered excellent results from strategic, operational and financial perspectives. We continued to advance our climate leadership strategy and added Alberta’s first utility-scale battery storage project, WindCharger, to our sizable hydro and wind fleet” – said Dawn Farrell, President and Chief Executive Officer. “TransAlta has been a leader in emissions reductions in Alberta since 2005 and we will continue to use this expertise to serve customers with low-cost, reliable, green electricity.”

“In another major milestone, our Board approved closing the Highvale Mine by Dec. 31, 2021, four years ahead of our original off-coal schedule for this mine. This decision demonstrates how we continue to lead our industry in achieving ESG milestones on an accelerated basis. I would like to express my sincere gratitude to the front-line employees of SunHills Mining who have worked tirelessly to provide exceptional service since the 1950s.”

Below are additional highlights from the quarter regarding how TransAlta is advancing its Clean Energy Investment Plan, how it is working toward greater diversity and inclusion, how the Company is managing COVID-19, as well as more details regarding the Company’s liquidity and financial position.

Clean Energy Investment Plan

Conversion to Gas

The Company will discontinue all mining operations at Highvale Mine by Dec. 31, 2021. Effective Jan. 1, 2022, the Company will cease coal-fired generation in Canada. TransAlta’s Keephills Unit 1 and Sundance Unit 4 will discontinue firing with coal and will only operate on gas, resulting in the maximum capability of these units being reduced to 70 MW and 113 MW, respectively, effective Jan. 1, 2022. The Company continues to evaluate these units as candidates for boiler conversion or full repowering based on market fundamentals.

TransAlta’s conversion programs are underway. The Company commenced the conversion outage of Sundance Unit 6 during the quarter and is on-track to complete the project by mid-Nov. 2020. The Company continues to advance the conversions of its Keephills Unit 2 and Unit 3 planned for 2021 and has issued Full Notice to Proceed for both units. During the third quarter of 2020, the Sundance Unit 5 repowering project received Board approval and is on-track to reach commercial operation in the fourth quarter of 2023.

In furtherance of the Company’s natural gas fuel supply needs for the converted units, TransAlta has long-term natural gas delivery transportation agreements with NGTL, bringing the cumulative total of new and existing pipeline transportation service to the Company’s generating facilities up to 400 terajoules (TJ) per day by 2023. TransAlta’s current commitments, including its 139 TJ/day supply arrangement with Tidewater, will remain in place until the closing of the Pioneer Transaction. The Pioneer Transaction is subject to customary regulatory approvals, which are currently expected to be obtained in the second quarter of 2021.

WindCharger Battery Storage

TransAlta announced that its 10 MW/20 MWh WindCharger Battery Storage project began commercial operation on Oct. 15, 2020. This project has a total capital cost of approximately $14 million, with approximately 50 per cent being funded through the support of Emissions Reduction Alberta. TransAlta will pay TransAlta Renewables Inc. a fixed monthly capacity charge for the right to operate and dispatch the battery in the Alberta market.

Windrise Wind

Construction activities on the Windrise Wind project continues to advance with all appropriate procedures in place to protect the construction team during the COVID-19 pandemic. This project is approximately 45 per cent complete (as at Sept. 30, 2020) and the construction schedule has been modified to reflect a COVID-19-related delay in the delivery of the wind turbine components. The Company plans to complete construction and commissioning in the second half of 2021. This project began receiving wind turbine generators on site in mid-Oct. 2020.

Kaybob Cogeneration

The Company has advanced the Kaybob Cogeneration project, including the purchase of the reciprocating engine generator, generator step-up transformers, electrical building, and switchgear.

Diversity and Inclusion

The Board has adopted a Diversity and Inclusion Pledge that commits the Company to advancing diversity and inclusion in the workplace. By committing to this pledge, the Company will seek to remove systemic barriers that may prevent diverse employees from thriving, including visible minorities, Indigenous people, members of the LGBTQ+ community, persons with disabilities, and women. The persistent inequities around the world underscore the urgent need to address and alleviate racial, ethnic, and other tensions, to remove barriers that perpetuate these inequalities and to promote an inclusive working environment for all employees. TransAlta firmly believes that true diversity is good for the economy, it improves corporate performance, drives growth, and enhances employee engagement. The Diversity and Inclusion Pledge acknowledges these challenges and seeks to: (i) encourage conversations about diversity and inclusion within the workplace; (ii) expand education regarding diversity, equality and inclusion; (iii) create best practices that result in the establishment of programs and initiatives relating to diversity and inclusion within the workplace; and (iv) drive accountability by regularly reporting and evaluating the success of the Company’s programs and initiatives.

COVID-19 Response Update

The Company continued to implement its business continuity plan which ensured that: (i) employees who could work remotely did so; and (ii) employees who operate and maintain our facilities, and who were not able to work remotely, were able to work safely and in a manner that ensured they remained healthy. During the third quarter of 2020, the Company successfully brought employees who were working remotely back to the office without sacrificing health and safety standards. The Company’s facilities also remain fully operational and capable of meeting its customers needs. All of the Company’s offices and sites follow strict health screening and physical distancing protocols with personal protective equipment readily available. TransAlta maintains travel restrictions aligned to local jurisdictional guidance, enhanced cleaning procedures, revised work schedules, and other measures to protect staff and contractors. The Company continues to work and serve all of its customers and counterparties under the terms of the relevant contracts. TransAlta has not experienced interruptions to service requirements. Electricity and steam supply continue to remain a critical service requirement to all of the Company’s customers and have been deemed an essential service in all of the jurisdictions in which TransAlta operates.

Liquidity and Financial Position

The Company continues to maintain a strong financial position in part due to our long-term contracts and hedged positions. At the end of the third quarter 2020, TransAlta had access to $1.6 billion in liquidity, including $270 million of cash and cash equivalents. Subsequent to the quarter, the Company raised approximately $1.1 billion in additional liquidity to support its gas conversions and renewables construction. The Company is currently positioned with approximately $2.7 billion in liquidity.

In October, TransAlta completed an AU$800 million senior secured note offering, which is secured among other things, a first ranking charge over all assets of its South Hedland Power Station. The Company also received $400 million from the second tranche of financing from the Brookfield investment. In addition, TransAlta has access to additional capital through potential project financing of existing assets that are currently unencumbered. The Company expects to utilize existing cash and credit facilities for the debt maturing in 2020 and expects to refinance the debt maturing in 2022.

The Company also has approximately 90 per cent of its Alberta thermal baseload merchant generation hedged at approximately $53 per MWh for the remainder of 2020.

Financial Results

The Company reported its third quarter 2020 financial results with comparable EBITDA⁽²⁾ of $256 million compared to $249 million in the same period of 2019. Comparable EBITDA for the nine months ended Sept. 30, 2020 was $693 million, an increase of one per cent compared to 2019. Funds from operations (FFO)^(2,3) for the three and nine months ended Sept. 30, 2020 were $193 million for the quarter compared to $188 million in 2019 and $524 million year-to-date as compared to $512 million in 2019. All 2019 figures quoted exclude the impact of the one-time payment of $56 million received in the third quarter of 2019 for the early termination of the Sundance B and C power purchase arrangements (the “PPA Termination Payments”).

FCF⁽²⁾, one of the Company’s key financial metrics, totaled $106 million and $306 million for the three and nine months ended Sept. 30, 2020, respectively. FCF for the three and nine months ended Sept. 30, 2020 decreased by $8 million and increased by $48 million for the same periods, respectively, after adjusting for the PPA Termination Payments.

Comparable EBITDA, excluding the PPA Termination Payments, for the three and nine months ended Sept. 30, 2020 increased by $7 and $8 million, respectively, compared with the same periods in 2019 largely due to strong performance by TransAlta’s Energy Marketing, Centralia, and Wind and Solar segments, partially offset by lower performance at the Alberta Thermal and Hydro segments as well as higher corporate costs due to the impact of a total return swap that hedges share-based compensation.

The Company’s operations, maintenance and administration (OM&A) expenses for the three months ended Sept. 30, 2020 were consistent with the same period in 2019. OM&A for the nine months ended Sept. 30, 2020 increased by $6 million compared to the same period in 2019 as variability caused by the total return swap resulted in an increase of expense of $16 million for the period. In addition, OM&A costs increased by $6 million due to the addition of Ada cogeneration facility, Big Level and Antrim Wind projects and the renegotiation of the Fort Saskatchewan maintenance agreement. Excluding the impact of the total return swap and additional facilities, OM&A decreased by $16 million due to tighter cost controls, units remaining on reserve shutdown during the second quarter of 2020 at Centralia, lower labour costs across multiple segments and lower legal fees.

FCF for the nine months ended Sept. 30, 2020, excluding PPA Termination Payments that were received in third quarter of 2019, was driven primarily by higher segmented cash flows, lower sustaining and productivity capital expenditures and lower distributions paid to subsidiaries non-controlling interests. Segmented cash flows⁽¹⁾ for the three months ended Sept. 30, 2020 were $4 million lower compared to the same period in 2019 due to lower performance in the Alberta Thermal segment, mostly offset by higher performance in the Company’s Centralia, Australian Gas, Wind and Solar and Energy Marketing segments. Segmented cash flows for the nine months ended Sept. 30, 2020, were $43 million higher compared to the same period in 2019. This increase was primarily due to higher performance in the Company’s Centralia, North American Gas, Wind and Solar, and Energy Marketing segments, which was partially offset by lower performance in the Company’s Alberta Thermal and Hydro segments and impacts of the total return swap in the Corporate segment.

Total Comparable EBITDA(2)	256	305	693	741
Comparable EBITDA (1) (2) excluding the PPA Termination Payments	256	249	693	685

• Alberta Thermal: Comparable EBITDA, excluding the PPA Termination Payments, for the three and nine months ended Sept. 30, 2020, decreased $32 million and $87 million, respectively, compared to the same periods in 2019. This largely reflects the weaker power demand conditions driving lower Alberta wholesale power prices resulting in lower merchant production and lower margins.
• Centralia: Comparable EBITDA returned to normalized levels for the nine months ended Sept. 30, 2020. For the three months ended Sept. 30, 2020, increased by $14 million compared to the same period in 2019, primarily due to purchased power at a lower cost. For the nine months ended Sept. 30, 2020, comparable EBITDA increased by $65 million compared to the same period in 2019, primarily due to the impacts of an isolated and extreme pricing event in Mar. 2019 during which Centralia was unable to commit one of its units to physical production for day-ahead supply due to an unplanned forced outage repair. In addition, comparable EBITDA in 2020 benefited from dispatch optimization and the strengthening of the US dollar relative to the Canadian dollar.
• North American Gas: Comparable EBITDA for the three months ended Sept. 30, 2020 remained consistent compared to the same period in 2019 and for the nine months ended Sept. 30, 2020 decreased by $6 million compared with the same periods in 2019, primarily due to higher OM&A resulting from a change in passthrough provisions of a customer contract.
• Australian Gas: Comparable EBITDA for the three and nine months ended Sept. 30, 2020 increased by $5 million and $3 million, respectively, compared with the same periods in 2019 mainly due to timing of legal fees and the strengthening of the Australian dollar against the Canadian dollar.
• Wind and Solar: Comparable EBITDA for the three months ended Sept. 30, 2020 was consistent with the same period in 2019. Comparable EBITDA for the nine months ended Sept. 30, 2020 increased by $20 million compared with the same period in 2019 primarily due to the addition of the Big Level and Antrim wind facilities and higher production, partially offset by insurance proceeds received in 2019, lower Alberta pricing and the planned expiry of certain Wind power production incentives in 2019.
• Hydro: Comparable EBITDA for the three months ended Sept. 30, 2020 was consistent with the same period in 2019. Comparable EBITDA for the nine months ended Sept. 30, 2020 decreased by $9 million, compared with the same period in 2019, as lower energy and ancillary services revenues resulted from lower Alberta pricing and prior year’s true-up to Alberta Electric System Operator (AESO) transmission line losses, which were partially offset by higher production.
• Energy Marketing: Comparable EBITDA for the three and nine months ended Sept. 30, 2020 increased by $18 million and $27 million, respectively, compared to the same periods in 2019. Results were primarily attained from market volatility arising from extreme weather events in California during the quarter as well as continued strong performance from short-term strategies across various geographic regions in both the power and natural gas markets.
• Corporate: Corporate overhead costs for the three months ended Sept. 30, 2020 were consistent with the same period in 2019. Corporate overhead costs for the nine months ended Sept. 30, 2020 increased by $5 million compared to the same period in 2019. These changes were 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.

Consolidated Financial Highlights

Net loss attributable to common shareholders for the three months ended Sept. 30, 2020 was $136 million compared to earnings of $51 million in the same period in 2019. The decrease is largely due to lower revenues, coal inventory write-down, higher depreciation, increase in asset impairments and the PPA Termination Payments, which were partially offset by foreign exchange gains and income tax recoveries. Net loss attributable to common shareholders for the nine months ended Sept. 30, 2020 was $169 million compared to $14 million in the same period in 2019. The decrease is largely due to lower revenues, coal inventory write-down, higher depreciation, increase in asset impairments and the final PPA termination payment, which were partially offset by lower fuel, carbon compliance, purchased power costs, and foreign exchange gains.

Total sustaining capital expenditures⁽³⁾ of $99 million were $12 million lower compared to 2019 primarily due to higher planned major maintenance in our Alberta Thermal segment in 2019.

TransAlta Corporation (TransAlta or the Company) (TSX: TA) (NYSE: TAC) today reported its second quarter 2020 financial results, with comparable EBITDA⁽¹⁾ of $217 million compared to $215 million in the same period of 2019. EBITDA for the six months ended June, 30, 2020, was $437 million, in line with the same period last year. Funds from operations (FFO)^(1,2) for the three and six months ended June 30, 2020, increased approximately 3% and 2% to $159 million for the quarter compared to $155 million in 2019 and $331 million year-to-date as compared to $324 million in 2019.

FCF⁽¹⁾, one of the Company’s key financial metrics, totaled $91 million and $200 million for the three and six months ended June 30, 2020, an increase of $42 million and $56 million respectively. Year-to-date, the Company has generated FCF of $0.72 per share, a 41% increase compared to 2019.

“Second quarter results are in line with our expectations and continue to show strong EBITDA and free cash flow generation from our diversified fleet. With the support of our back-to-office protocols, we continue to deliver the essential power to meet the demands of our communities and our customers,”- said Dawn Farrell, President and Chief Executive Officer. “These results demonstrate the strength of our operations, hedging and energy marketing capabilities, as well as our people.”

“We also expanded our cogeneration fleet with the acquisition of our Ada cogeneration facility into our portfolio and welcomed Consumers Energy and Amway as new customers. We are excited to mark our first cogeneration facility in the United States and we look forward to building on this U.S. toehold as we further progress our on-site generation strategy into the region.”

“I’d like to thank all of our front-line employees, contractors and their families whose exceptional efforts keep up the strong operational performance of the Company in the face of these challenging times,” added Mrs. Farrell.

Comparable EBITDA for the three and six months ended June 30, 2020, were consistent with the same periods in 2019. This was driven by full period operations of the Big Level and Antrim facilities in the Company’s Wind and Solar segment, superior performance from the Energy Marketing segment, favourable gross margins from the U.S. Coal segment, and favourable gains resulting from equity hedge settlements and lower expenses in the Corporate segment. This favourable performance was offset by anticipated weaker margins in the Canadian Coal, Hydro and North American Gas segments resulting from weaker prices in both the Alberta market and the Ontario power markets due to lower market demand and the impact of COVID-19. The Canadian Coal comparable EBITDA in the quarter and year-to-date also declined due to recognition of a $7 million provision adjustment for out-of-period line losses relating to the Alberta Electric System Operator (AESO) Line Loss Rule proceeding.

Operations, maintenance and administration (OM&A) expense for the three and six months ended June 30, 2020, decreased by $18 million and increased by $6 million, respectively, compared to the same periods in 2019. Variability caused by the total return swap resulted in a decrease of $7 million and an increase of $17 million for the three month and six months ended June 30, 2020, respectively. Excluding the impact of the total return swap, OM&A decreased by $11 million in both periods, due to tighter cost controls, lower labour costs across multiple segments and lower legal fees.

FCF totaled $91 million and $200 million for the three and six months ended June 30, 2020, respectively. FCF for the three and six months ended June 30, 2020 increased by $42 million and $56 million, respectively, compared to the same periods in 2019. The increase was driven primarily by strong segmented cash flows, realized foreign exchange gains, lower sustaining capital expenditures and lower distributions paid to subsidiaries non-controlling interests. Segmented cash flows generated by the business are $47 million and $48 million dollars higher for the second quarter and year-to-date periods in 2020, respectively, compared with 2019, due to higher performance in our U.S. Coal, North American Gas, Wind and Solar and Energy Marketing segments that more than offset lower results in the Canadian Coal and Hydro segments.

Clean Energy Investment Program

Coal-to-Gas

TransAlta’s growth construction programs are underway and progressing forward under its business continuity health measures. The Company is on-track to complete the conversion of Sundance Unit 6 during the second half of 2020. The Company continues to advance conversion of its Keephills Unit 2 and Unit 3 planned for 2021 and has issued full notice to proceed for both units. We are on-track to issue full notice to proceed in 2021 for Sundance Unit 5, with an expected commercial operation date in 2023.

In furtherance of the coal-to-gas fuel supply needs, TransAlta entered into long-term natural gas delivery transportation agreements with NGTL, bringing the cumulative total of new and existing pipeline transportation service to the Company’s generating facilities up to 400 terajoules (TJ) per day by 2023. TransAlta’s current commitments, including its 139 TJ/day supply arrangement with Tidewater Midstream and Infrastructure Ltd., will remain in place until the closing of the Pioneer Transaction. The Pioneer Transaction is subject to customary regulatory approvals, which are currently expected in the second half of 2021.

Sundance 3

On July 22, 2020, the Company announced that it gave notice to the AESO of its intention to retire the currently mothballed coal-fired Sundance Unit 3 effective July 31, 2020. The retirement decision was largely driven by TransAlta’s assessment of future market conditions, the age and condition of the unit and the ability to supply energy and capacity from our generation portfolio in Alberta. This decision advances our transition to 100 per cent clean electricity by 2025. An asset impairment of approximately $69 million ($52 million after-tax) will be recorded in the third quarter of 2020.

Windcharger Battery Storage

Construction for Windcharger, Alberta’s first battery storage project, is in its final stages and will achieve its commercial operations date in August 2020.

Windrise Wind

Construction activities on the Windrise Wind Project continues to advance with all appropriate procedures in place to protect the construction team during the COVID-19 pandemic. The construction schedule has been modified to reflect a COVID-19-related delay in the delivery of the wind turbine components and the Company plans to complete construction and commissioning in second half of 2021.

Kaybob Cogeneration

The Company continues to advance the Kaybob Cogeneration Project with commercial operations scheduled to commence in the second half of 2021; however, the Company continues to monitor COVID-19 and market conditions to determine if any adjustments to plans are necessary. During the first half of 2020, TransAlta executed agreements for the purchase of the reciprocating engine generator, generator step up transformers, electrical building and switchgear. The project secured a municipal development permit in March 2020 and Alberta Energy Regulator permit approval in early April 2020.

Board of Director Changes

On July 30, 2020, Mr. Robert Flexon delivered his resignation from the Board, which is to be effective August 1, 2020. Mr. Flexon recently assumed the role of Chair of the Board of Directors of PG&E Corporation (PG&E) and is resigning from the Board due only to the potential for perceived conflicts of interests between PG&E and the Company. Mr. Flexon has provided valuable insight during his time on the Board, which included acting as the inaugural chair of the Investment Performance Committee of the Board.

COVID-19 Response Update

The Company formally implemented its business continuity plan on March 9, 2020, which focused on ensuring that: (i) employees that could work remotely did so; and (ii) employees that operate and maintain our facilities, and who were not able to work remotely, were able to work safely and in a manner that ensured they remained healthy. During the second quarter of 2020, the Company began a staggered approach to bring employees that were working remotely back to the office. All of TransAlta’s offices and sites follow strict health screening and social distancing protocols with personal protective equipment readily available. 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 the Company’s results have been impacted by price and demand as a result of COVID-19, all of the Company’s facilities remain fully operational and capable of meeting its customers needs. The Company has modified its operating procedures and implemented safety protocols that are allowing all office employees to now return to sites across the fleet by end of July.  The Company continues to work and serve all of its customers and counterparties under the terms of the relevant contracts. TransAlta has not experienced interruptions to service requirements. Electricity and steam supply continue to remain a critical service requirement to all of the Company’s customers and have been deemed an essential service in all of the jurisdictions in which TransAlta operates.

The Company continues to maintain a strong financial position in part due to its long-term contracts and hedged positions. The Company is scheduled to receive $400 million from the second tranche of financing from the Brookfield investment in the fourth quarter of 2020 and has access to additional capital through potential project financing of existing assets that are currently unencumbered. The Company currently has access to $1.6 billion in liquidity including $257 million in cash and has sufficient liquidity to meet the upcoming debt maturity due November 2020 and growth construction requirements. The next major debt repayment is scheduled for November 2022.

In addition, the Company has approximately 75 per cent of its Alberta thermal baseload merchant generation hedged at approximately $53 per MWh for the remainder of 2020.

Total Comparable EBITDA(2)	217	215	437	436

• Canadian Coal: Comparable EBITDA for the three and six months ended June 30, 2020, decreased $36 million and $55 million, respectively, compared to the same periods in 2019. This largely reflects the weaker power demand conditions driving lower Alberta wholesale power prices and resulting in lower merchant production as well as the increase to the transmission line loss provision.
• U.S. Coal: Comparable EBITDA returned to normalized levels in 2020 and for the three months ended June 30, 2020, increased by $8 million compared to the same period in 2019, primarily due to low priced power purchases and favourable foreign exchange rates. For the six months ended June 30, 2020, comparable EBITDA increased by $51 million compared to the same period in 2019, primarily due to the impacts of an isolated and extreme pricing event in March 2019 during which Centralia was unable to commit one of its units to physical production for day-ahead supply due to an unplanned forced outage repair. In addition, comparable EBITDA in the first half of 2020 benefited from low-priced power purchases and the strengthening of the U.S. dollar relative to the Canadian dollar.
• North American Gas: Comparable EBITDA for the three and six months ended June 30, 2020, decreased by $4 million and $5 million, respectively, compared with the same periods in 2019, due to lower power prices in Alberta and Ontario.
• Australian Gas: Comparable EBITDA for the three and six months ended June 30, 2020, decreased by $2 million for both periods compared with the same periods in 2019, mainly due to the weakening of the Australian dollar relative to the Canadian dollar.
• Wind and Solar: Comparable EBITDA for the three and six months ended June 30, 2020, increased by $14 million and $19 million, respectively, compared with the same periods in 2019, primarily due to higher production related to the Big Level and Antrim wind facilities, which were commissioned in December of 2019, partially offset by insurance proceeds received in 2019.
• Hydro: Comparable EBITDA for the three and six months ended June 30, 2020, decreased by $8 million and $9 million, respectively, compared with the same periods in 2019, as lower energy and ancillary services revenues were impacted by lower Alberta pricing, which was partially offset by higher production.
• Energy Marketing: Comparable EBITDA for the three and six months ended June 30, 2020, increased by $15 million and $9 million, respectively, compared to the same periods in 2019. Results were primarily attained from short-term strategies across various geographic regions in both the power and natural gas markets.
• Corporate: Corporate overhead costs for the three months ended June 30, 2020, decreased by $15 million and for the six months ended June 30, 2020, increased by $7 million compared to the same periods in 2019. These changes were primarily due to realized gains and losses from the total return swap. A portion of the settlement cost of our share-based payment plans is fixed by entering into total return swaps, which are cash settled every quarter.

Consolidated Financial Highlights

Net loss attributable to common shareholders for the three months ended June 30, 2020, was $60 million compared to nil in the same period in the prior year. The decrease is largely due to lower revenues, higher depreciation, asset impairment and lower income tax recoveries partially offset by lower OM&A and foreign exchange gains. Net loss attributable to common shareholders for the six months ended June 30, 2020, was $33 million, compared to a loss of $65 million in the same period in 2019, an improvement of $32 million. Stronger earnings from our U.S. Coal and Wind and Solar segments, foreign exchange gains and a reduction in the Centralia mine decommissioning provision due to changes in discount rates resulting in an asset impairment reversal were partially offset by higher depreciation, higher interest expense and lower income tax recoveries.

Total sustaining capital expenditures ⁽²⁾ of $55 million were $31 million lower compared to 2019 primarily due to higher planned major maintenance in our coal segments in 2019.
