Effects of grid expansion on market power in the fossil fuel industry

In “Wiring America,” EPIcenter affiliate Gaurav Doshi analyzes how Texas’s CREZ high-capacity transmission build-out curbed the market power of fossil-fuel generators. Using a two-stage empirical strategy, the study first shows that CREZ reduced wind curtailment, adding roughly 0.11 GWh of additional wind during peak hours and 0.22 GWh at the off-peak – and then demonstrates […]

Curtailment 101: Understanding the Basic Economic Trade-Offs

Listen to the Curtailment 101 podcast: EPIcenter affiliates Gaurav Doshi and Matthew Oliver’s article in The Energy Forum discusses the why grid operators occasionally curtail wind and solar output when transmission capacity is insufficient or demand is low, and the economic and environmental impacts of these decisions. Congestion-based curtailment arises when the transmission network cannot […]
