• Electricity generation from hydro, wind, gas and thermal assets
• Wholesale power sales and merchant market exposure
• Contracted power supply and capacity availability
• Environmental and tax attribute sales
• Hedging and power marketing activities

- **Power generation** (70%) — Electricity produced from the company's hydro, wind, gas and thermal generation fleet.
- **Wholesale energy marketing** (15%) — Merchant power sales and market-based electricity trading and settlement.
- **Contracted capacity and supply** (10%) — Longer-term contracted generation, capacity and tolling-style arrangements.
- **Environmental attributes** (5%) — Sales of emission credits, renewable attributes and related environmental products.

- Electricity generation from hydro, wind, gas and thermal assets
- Wholesale power sales and merchant market exposure
- Contracted power supply and capacity availability
- Environmental and tax attribute sales
- Hedging and power marketing activities

## Customers

TransAlta sells electricity and capacity to utilities, commercial and industrial customers, and counterparties in wholesale power markets. A portion of output is sold under contracts, while the rest is exposed to spot prices and ancillary-services markets, so customer mix varies by asset and region. Environmental attributes and emission credits are typically sold to buyers seeking compliance or sustainability instruments.

- **Utilities and regulated buyers** (primary) — Purchase contracted electricity and capacity for reliable supply and grid support.
- **Commercial and industrial customers** (primary) — Buy power under bilateral contracts for price stability and energy procurement.
- **Wholesale power markets** (primary) — Buy and sell electricity, ancillary services and merchant volumes in market pools.
- **Environmental attribute buyers** (secondary) — Purchase emission credits and related attributes for compliance or carbon goals.

- Utilities buying contracted electricity and capacity
- Industrial and commercial users seeking power supply
- Wholesale market counterparties in Alberta and other regions
- Buyers of renewable and emission-credit attributes
- Counterparties to hedge and settlement transactions

## Geography

TransAlta operates across Canada, the United States and Western Australia, with exposure to regional power prices, weather patterns and grid conditions. The Alberta market is especially important because merchant power, ancillary services and hedge settlements are tied to local pricing, while Eastern Canada affects hydro and wind availability. Its asset base and customer exposure are geographically diversified, but performance can still be shaped by local resource conditions and contract renewals.

- Canada is the core operating base and pricing reference
- Alberta market affects merchant power and ancillary services
- United States assets add cross-border generation exposure
- Western Australia extends the portfolio beyond North America
- Weather and resource variability affect hydro and wind output

## Strategy

TransAlta's strategy centers on operating a diversified fleet, managing commodity and merchant exposure, and using contracts and hedges to support cash-flow visibility. The company also focuses on selective asset additions and portfolio optimization to strengthen its position in power markets and extend the life of its generation base. Its operating model emphasizes dependable dispatch, market access and disciplined capital allocation across regions.

- **Diversify generation and contract exposure** (medium-term) — A mixed fleet and contract base help reduce dependence on any one fuel, market or weather pattern.
- **Use hedging and market positioning** (short-term) — Hedging and structured market participation help manage price volatility and settlement risk.
- **Optimize the asset portfolio** (medium-term) — Acquisitions, retirements and portfolio changes can improve operating fit and market exposure.

- Maintain a diversified generation mix across hydro, wind, gas and thermal
- Balance merchant exposure with contracts and hedging
- Optimize asset portfolio through acquisitions and retirements
- Develop opportunities in existing and adjacent power markets
- Support dependable operations across multiple jurisdictions

## Risks

TransAlta is exposed to volatile power prices, weather-driven generation variability and operational outages because much of its revenue depends on dispatch, spot markets and resource availability. The business also faces contract renewal risk, regulatory and carbon-compliance exposure, and derivative-accounting complexity from its hedging program. Asset retirements, maintenance needs and market-specific pricing dynamics can materially affect reported results and cash generation.

- **Merchant power price volatility** [high] — A meaningful share of generation is sold into spot and ancillary-services markets, creating price sensitivity.
- **Weather and resource variability** [high] — Hydro flows, wind conditions and availability directly affect output and revenue.
- **Contract renewal and facility retirement risk** [medium] — Renewals at lower prices or retired assets can reduce revenue from contracted generation.
- **Regulatory and carbon compliance exposure** [medium] — Electric generators face emissions rules, compliance obligations and attribute-market changes.

- Power price volatility affects merchant revenue and hedge settlements
- Weather and resource variability change hydro and wind output
- Contract renewals can reset prices lower on key facilities
- Operational outages reduce generation and revenue
- Carbon and environmental compliance affect costs and attribute sales

## Accounting

TransAlta's results are sensitive to hedge accounting, derivative valuation and fair-value movements because it uses financial contracts to manage electricity price exposure. Revenue and earnings can also be affected by mark-to-market gains or losses, the timing of hedge settlement, and changes in environmental attribute sales. Management judgment is important in estimating asset lives, impairment, and the recoverability of generation assets and contractual positions.

- **IFRS 9 hedge accounting for VPPAs** — Effective hedge gains go to OCI; ineffective portions affect net earnings.
- **Derivative fair-value measurements** — Affects reported revenue, other income and earnings volatility.
- **Environmental attribute recognition** — Affects energy revenue and period-to-period comparability.
- **Asset impairment and depreciation** — Affects depreciation expense and potential impairment charges.

- Hedge accounting changes OCI vs net earnings timing
- Mark-to-market gains and losses affect reported revenue and earnings
- Environmental attribute revenue can vary with market sales volume
- Asset lives and impairments affect depreciation and carrying values
- Acquisition accounting can add integration and fair-value estimates
