TransAlta Reports Third Quarter 2013 Results

CALGARY, ALBERTA--(Marketwired - Oct. 31, 2013) - TransAlta Corporation ("TransAlta") (TSX:TA) (NYSE:TAC) today reported third quarter 2013 Comparable EBITDA⁽¹⁾ of $266 million compared to $255 million during the same period last year. For the nine month period ending September 30, 2013, Comparable EBITDA is higher by $79 million. We also declared a quarterly dividend of $0.29 per share.

Operating highlights include increased comparable gross margins compared to the same period last year, largely driven by the performance of the Gas, Renewables and Trading business lines as well as contributions from new growth projects. In addition, we made substantial advances on our growth and recontracting strategies. Since the second quarter, we secured a total of 369 megawatts ("MW") in long-term contracts in Eastern Canada, Australia and the U.S which brings the total for the year to approximately 835 MW. We also created TransAlta Renewables, establishing a vehicle for pursuing growth opportunities and generating proceeds to pay down debt, which was the primary driver of debt balances declining by $343 million in the quarter. Furthermore, we added 213 MW of long-term contracted wind assets to the portfolio, and are capturing a full year of the Solomon acquisition in 2013.

"We set out this year to add long term contracts, advance our growth strategy, improve our marketing business and run a strong operation," said Dawn Farrell, President and CEO. "Results in the third quarter reflect a solid performance by our team on all of these fronts."

Q3 2013 compared to Q3 2012

• Comparable EBITDA of $266 million up from $255 million for the same period last year
• FFO⁽¹⁾ of $174 million down from $233 million for the same period last year
• Availability of 85.9% as compared to our annual target of 89-90%. Lower availability is primarily attributed to the force majeure at Keephills Unit 1

YTD 2013 compared to YTD 2012

• Comparable EBITDA of $780 million up from $701 million for the same period last year
• FFO of $550 million down from $572 million for the same period last year
• Adjusted availability⁽²⁾ of 86.4% as compared to our annual target of 89-90% Lower availability is primarily attributed to the force majeure at Keephills Unit 1

Third Quarter Business Line Review

• Coal: Comparable gross margins, adjusted for mining depreciation and coal inventory write-downs were $182 million, a decrease of $37 million compared to the same period last year. The decrease is primarily due to lower contract pricing at Centralia Thermal and unfavorable coal pricing at the Alberta coal facilities.

• Gas: Comparable gross margins, including finance lease income were $102 million, an increase of $14 million compared to same period last year. The increase is due to the addition of Solomon and favorable gas input costs in Eastern Canada.

• Renewables: Comparable gross margins were $91 million, an increase of $3 million compared to the same period last year. The increase is primarily due to favorable pricing, partially offset by lower hydro and wind volumes in Western Canada and lower hydro volumes in Eastern Canada.

• Energy Trading: Comparable gross margins were $22 million, an increase of $38 million compared to the same period last year. The increase is primarily due to strong performance across all markets and prudent management of risk.

Third Quarter Consolidated Financial Review

Comparable EBITDA was $266 million up from $255 million for the same period last year, reflecting the higher gross margins in Gas, Renewables and Trading, which more than offset lower contract pricing at Centralia Thermal, higher rolling average power prices during certain planned outages in Alberta, and higher coal costs associated with mining coal in advance of the start-up of Sundance Units 1 and 2. On a year to date basis, Comparable EBITDA was $780 million, an increase of $79 million from the same period last year.

Despite higher EBITDA, FFO for the quarter was $174 million down from $233 million for the same period last year. The decrease in FFO is primarily due to differences in timing of cash proceeds associated with power hedges and coal inventories.

Comparable earnings for the quarter were $39 million ($0.15 per share) down from $41 million ($0.18 per share) in the same period last year. The per share decrease was largely driven by higher shares outstanding compared to the same period last year.

(2) Adjusted for economic dispatching at Centralia.

A net loss $9 million ($(0.03) per share) was recorded for the third quarter down from $56 million ($0.24 per share) in the same period last year. This decrease is largely due to a $40 million deferred tax asset write off at Centralia Thermal.

Third Quarter Operating Review

• Fleet availability was 85.9% compared to 90.9% over the same period last year, largely due to the force majeure declared during the first quarter of 2013 at Keephills Unit 1. We expect our full year availability to be 87-89%, adjusted for economic dispatching at Centralia Thermal.

• Excluding the force majeure at Keephills Unit 1, availability in the quarter was approximately 91% and full year adjusted availability would be within our target range of 89-90%.

• We have completed three of four major outages scheduled for 2013.

• Total sustaining expenditures were $93 million for the quarter and $245 million year-to-date. We are tracking to our target range of $295-$345 million for 2013.

Recent Events

Western Australia Contract Extension

On Oct. 30, 2013, we announced a long-term contract extension to supply power to the BHP Billiton Nickel West operations in Western Australia from our Southern Cross Energy facilities ("Southern Cross"). The extension is effective immediately and replaces the previous contract which was set to expire at the beginning of 2014.

Operating since 1996, Southern Cross has a total installed capacity of 245 MW from the Kambalda, Mt. Keith, Leinster, and Kalgoorlie power stations.

Acquisition by TransAlta Renewables

On Oct. 21, 2013, TransAlta Renewables announced the acquisition, through one of our wholly owned subsidiaries, of an economic interest in a 144 MW wind farm in Wyoming for approximately U.S. $102 million from a wholly owned subsidiary of NextEra Energy Resources, LLC. The wind farm is fully operational and contracted under a long-term PPA until 2028 with an investment grade counterparty. At closing, the economic interest in the wind farm will be acquired by TransAlta Renewables from the Corporation in consideration for a payment equal to the original purchase price of the acquisition. We will fund the acquisition through a U.S.$102 million loan to TransAlta Renewables. TransAlta Renewables expects to repay the loan with free cash flow from operations over the first 36 months and through a long-term debt refinancing that is expected to be completed in conjunction with other financing needs of TransAlta Renewables. The acquisition is subject to regulatory approvals and is expected to close by the end of December 2013. The acquisition is expected to be accretive to cash flow per share for both the Corporation and TransAlta Renewables.

TransAlta Renewables Inc. ("TransAlta Renewables")

On August 9, 2013, we transferred 28 indirectly owned wind and hydroelectric generating assets to TransAlta Renewables through the sale of all the issued and outstanding shares of two subsidiaries: Canadian Hydro Developers, Inc. and Western Sustainable Power Inc. The initial public offering resulted in an aggregate of 22.1 million common shares being issued for gross proceeds to Renewables of $221 million. TransAlta, directly and indirectly, holds 92.6 million common shares, representing approximately 80.7% of the common shares in Renewables.

Ontario Power Authority

On August 30, 2013, we announced the execution of an agreement for a 20-year power supply term with the Ontario Power Authority for our Ottawa gas facility, effective January, 2014. Under the new deal, the plant will become dispatchable. This will assist in reducing the incidents of surplus baseload generation in the market, while maintaining the ability of the system to reliably produce energy when it is needed.

This new contract will benefit our shareholders by providing long-term stable earnings from this facility and will benefit ratepayers of Ontario by securing attractively priced capacity from this existing facility, reducing the need for new capacity to be built in the future and allowing hospitals in the area to continue to be served with the steam they need for heat and other energy processes, in an environmentally friendly manner.

Salt River Project

On September 17, 2013, we announced that CalEnergy, LLC, a joint venture between TransAlta and MidAmerican Energy Holdings Company, executed a 50 MW long-term contract for renewable geothermal power with Salt River Project, an Arizona utility, which runs from 2016 to 2039.

Sundance Units 1 and 2 Return to Service

In December 2010, Units 1 and 2 of our Sundance facility were shut down due to conditions observed in the boilers at both units. On July 20, 2012, an arbitration panel concluded that Unit 1 and Unit 2 were not economically destroyed. Unit 1 was returned to service on September 2, 2013 and Unit 2 was returned to service on October 4, 2013.
