The value of transmission in electricity markets: Evidence from a nuclear power plant closure
Lucas W. Davis, Catherine Hausman 16 June 2014
Estimating the economic value of energy transmission is difficult because investments in transmission capacity are endogenous to market conditions. This column presents recent research that takes advantage of a natural experiment to generate a credible counterfactual. The unexpected closure of the San Onofre Nuclear Generating Station in California increased generation costs by $350 million per year; it also led to increased carbon emissions worth $320 million annually.
Just as free trade in goods offers opportunities for efficiency gains, electricity transmission infrastructure facilitates exchange in electricity markets. The first-order effects of geographic integration in electricity markets are straightforward – allocation of production across firms is improved, so lower cost generating resources can be used to meet demand.

Nuclear expansion or phase-out? Costs and opportunities
Enrica De Cian, Samuel Carrara, Massimo Tavoni 22 December 2013
After the Fukushima incident in 2011, many countries decided to shrink their nuclear power programmes. This article presents recent research on the optimal role of nuclear power in reducing carbon emissions. Phasing out nuclear power would be costly, since it is currently the cheapest low-carbon alternative to fossil fuels. However, these costs would be largely offset by the implicit subsidy to R&D in renewables, which suffers from innovation externalities. Still, carbon pricing and explicit R&D subsidies would be a more efficient way of determining the future of nuclear power.
"We learned from Fukushima that we have to deal differently with risks… We believe we as a country can be a trailblazer for a new age of renewable energy sources… We can be the first major industrialized country that achieves the transition to renewable energy with all the opportunities – for exports, development, technology, jobs – it carries with it.” Angela Merkel (distinct quotes).
