In fiscal 2025, TransAlta delivered adjusted EBITDA of $349 million in Q2, up $33 million year over year, driven by strong hydro performance and disciplined hedging. Free cash flow held steady at $177 million ($0.60 per share), while average fleet availability reached 91.6%, underscoring operational reliability.
Hydro earnings surged to $126 million, a 52% increase, offsetting softness in gas and energy marketing due to lower Alberta power prices and subdued market volatility. The company reaffirmed full-year guidance for $1.15–$1.25 billion in adjusted EBITDA and $450–$550 million in free cash flow.
CEO John Kousinioris highlighted the company’s progress on several fronts: an expanding renewables footprint, a strategic investment in Nova Clean Energy, and the advancement of Alberta’s emerging data-center capacity strategy, which could be a new demand driver for the province’s power market. With a 19% YTD stock gain, TransAlta’s story in 2025 is one of operational discipline meeting strategic reinvention.

Financial Story
TransAlta’s second-quarter results illustrated how effective portfolio diversification can buffer market cyclicality. Alberta’s merchant power prices fell to $40/MWh, but strong hedge coverage (1,900 GWh at $70/MWh) protected margins. The hydro fleet was the clear standout, benefiting from exceptional water conditions and higher ancillary-service revenues. The gas portfolio faced mild-weather impacts and higher carbon-compliance costs, while the wind and solar segment held steady thanks to full-quarter contributions from White Rock and Horizon Hill.

| Free Cash Flow | $177 M ($0.60/share) | Flat | Higher taxes & sustaining capex |
| Fleet Availability | 91.6% | +150 bps | Reliability improvements |
| Hydro EBITDA | $126 M | +52% | Higher merchant & ancillary revenue |
| Wind & Solar EBITDA | $89 M | Flat | Strong volume, stable pricing |
| Gas EBITDA | $128 M | −10% | Lower Alberta spot & higher fuel cost |
| Energy Transition EBITDA | $19 M | +850% | Lower fuel & purchased power |
| Energy Marketing EBITDA | $26 M | −33% | Weaker market volatility |
| Alberta Spot Price | $40/MWh | −11% | Hedged at $70 → 75% premium |

Despite uneven segment performance, TransAlta’s overall cash generation remained robust. Higher sustaining capital and tax payments offset EBITDA gains, but balance-sheet strength was undiminished. The company ended the quarter with more than $1.5 billion in available liquidity and $238 million in cash, providing ample flexibility for capital returns, acquisitions, and project financing. The reaffirmation of 2025 guidance underscores confidence in its hedged position and expanding contracted earnings base.

Broader Market Context
Alberta’s electricity market is in transition. The province’s deregulated framework has encouraged new renewable capacity, creating short-term price pressure but long-term resilience. TransAlta remains a dominant player, operating roughly 25% of Alberta’s generation capacity across multiple fuel types. The company’s ability to hedge power at substantial premiums to spot, often 60–100% higher, highlights its trading acumen and market foresight.
Beyond Alberta, TransAlta is leaning into cross-border growth. Its investment in Nova Clean Energy grants access to over 4 GW of late-stage U.S. renewable projects, positioning the company for a decade of pipeline expansion. Management is also exploring mid-life natural gas acquisitions in the Pacific Northwest and Ontario, reflecting a pragmatic approach to decarbonization: secure baseload generation today while funding renewables for tomorrow.
1. Hydro Strength and Hedging Precision
Hydro was the star of Q2 2025, not only for operational performance but for price realization. The segment’s realized merchant price of $82/MWh represented a 105% premium to the provincial average. Strong water inflows, disciplined dispatch, and opportunistic hedging enabled TransAlta to capture value even in a weak pricing environment. With 126 million EBITDA, hydro’s contribution nearly doubled year-over-year, offsetting declines in gas and marketing.
These results highlight the company’s core competency in asset optimization. By actively managing generation schedules and leveraging real-time trading, TransAlta consistently monetizes volatility rather than succumbing to it. Its hedge book, 4,300 GWh contracted for the remainder of 2025 and 7,000 GWh for 2026 at $67/MWh, provides rare visibility in a deregulated market. This hedge discipline remains central to maintaining steady free cash flow and shareholder returns.
2. Gas and Energy Marketing: Navigating Headwinds
The gas segment’s $128 million in EBITDA declined 10% year over year, reflecting lower realized power prices and higher fuel and carbon costs. Heartland Generation, acquired in late 2024, added volume but also raised operating and maintenance expenses. Still, TransAlta’s gas fleet maintained strong reliability, with availability above 90%, and remains strategically vital as Alberta integrates intermittent renewables.
Energy marketing was the quarter’s weakest link, down $13 million year over year to $26 million. Reduced market volatility across North America’s gas and power markets limited trading opportunities. Management expects normalization in the back half of 2025, supported by growing cross-border trading and renewable-credit arbitrage. Even with short-term softness, the segment remains a valuable hedge against generation risk, helping stabilize earnings over the cycle.

3. Strategic Growth: Renewables, Data Centers, and M&A
Beyond quarterly results, TransAlta’s long-term strategy is taking shape. Its partnership with Nova Clean Energy gives it exclusive purchase rights to U.S. wind and solar projects, enabling scalable growth outside Alberta’s saturated market. Meanwhile, the company’s Alberta data-center initiative could become a transformative demand driver, the provincial ISO has already allocated 1,200 MW of capacity to potential participants, including TransAlta. As hyperscale demand rises, data centers could meaningfully lift baseload requirements and system reliability needs, areas where TransAlta’s hybrid portfolio excels.
On the M&A front, management signaled growing interest in mid-life natural-gas assets in the Pacific Northwest and Ontario, leveraging its operational and trading expertise to extract value where others see decline. Combined with a stable dividend and NCIB buybacks, the strategy reflects balanced capital allocation: fund growth through free cash flow while maintaining shareholder discipline. The result is a company built for both yield and upside.
The TIKR Takeaway
TransAlta’s steady climb from a legacy thermal producer to a diversified, renewables-leaning utility is one of the more underrated turnaround stories in Canadian energy. Strong hedging, disciplined execution, and exposure to emerging growth drivers like data centers are paying off. The stock’s 19% year-to-date rally reflects renewed investor confidence in its predictable cash flows and strategic optionality.
With energy transition policy tailwinds, a robust pipeline of growth projects, and best-in-class risk management, TransAlta is positioned to compound steadily. Short-term pricing headwinds remain, but the company’s diversified fleet and hedge profile continue to smooth volatility while funding the next leg of clean-power expansion.
