What it stands on, and what could break it
What the business leans on
- 1Nuclear plants need uranium fuel and specialist conversion, enrichment and fuel-fabrication services; some supply chains involve international suppliers, including Russia.
- 2Gas-fired plants and natural-gas customers depend on gas purchases, pipelines and storage, as well as fuel prices.
- 3Revenue and costs depend on electricity prices, customer demand and market rules in the regional power markets where the company generates and sells electricity.
- 4Nuclear plants depend on operating licenses, regulatory approvals, safe plant operation and arrangements for storing and disposing of nuclear waste.
What could go wrong
- 1Changes in wholesale electricity prices, fuel costs, customer demand or market rules can affect the revenue from generation and the cost of buying power to meet customer contracts.
- 2Nuclear plant outages, safety incidents, fuel-supply disruptions or regulatory decisions could interrupt generation, raise costs or limit the operation of plants.
- 3Integrating Calpine and completing required asset sales involve execution and regulatory steps; delays or problems could disrupt operations or prevent the company from achieving the intended benefits of the acquisition.
