Vistra Corp (VST)
NYSE
Nuclear Energy
Power Generation
Investment Thesis
Vistra is the largest competitive power generator in the US — a mix of nuclear, natural gas, and rapidly growing battery storage. Their Illinois nuclear fleet benefits from the same hyperscaler demand driving Constellation. Vistra is cheaper on a per-MWh basis and has a more diversified generation mix, making it the value play in the nuclear power trade.
Key Drivers
- Illinois Nuclear Fleet: 6 nuclear units providing reliable baseload — all in areas of high data centre demand.
- Battery Storage Leader: 6+ GWh of battery storage capacity — the largest in the US.
- Power Price Leverage: In competitive electricity markets, rising power prices flow directly to earnings.
Risk Factors
- Market Power Prices: Earnings are sensitive to regional electricity market prices (ERCOT, PJM).
- Concentrated Generation Mix: Nuclear concentration means any plant issue has outsized impact.
