Gas-Power Linkage and Dispatch Economics

Gas hubs and power prices are tightly linked where gas-fired generation is marginal, making heat rates and spark spreads central to monitoring.

Core Points

  • Power dispatch stack determines gas demand elasticity.
  • Carbon cost can shift relative competitiveness of fuel types.
  • Plant outages and renewables variability influence prompt burn.

Case Studies

Case: Low Wind, High Gas Burn

Weak wind output raised thermal dispatch needs, lifting gas burn and tightening near-term hub balances.

Case: Carbon Price Shift in Dispatch

A rise in carbon prices changed relative generation economics, altering gas-vs-coal dispatch and spread behavior.
