This dissertation studies the impact of energy policy on U.S. electricity markets and energy transition. The first chapter examines the impact of grid expansion on market power and emissions from fossil fuel firms in the short-run and the transition to wind energy in the long-run. For the empirical analysis, I use the rollout of a large-scale transmission expansion project in Texas that linked windy areas in the west to population centers in the east, costing $6.8 billion. Results show significant benefits due to declines in markups, emissions, and increases in wind investment. The payback periods range from 5 - 12 years and are much shorter than the previous estimates in the literature. In the second chapter, I study the effect of market structure on technology adoption in the U.S. solar and wind power industries. I compare adoption across two market types: restructured markets, which are designed to promote competition, and traditional markets, which are dominated by regulated monopolists. Solar projects in restructured markets are 24 percent less likely to adopt frontier technology, while the effect for wind projects is negative but statistically insignificant. I provide evidence that differences in financing costs across the two market types explain this negative relationship between competition and adoption. In the third chapter, I study the effect of transmission expansion on the cost of hedging risk in the wholesale electricity market. Market participants (generating firms, retailers, and financial traders) use forward contracts to hedge risk from price volatility in the market. I show that transmission integration in Texas significantly lowered the prices of these contracts, which translates to about $265 million worth of annual benefits in terms of lower cost of hedging risk. Further, I show evidence of greater market efficiency measured by the geographical convergence of prices across regions in Texas.
