California emissions rise on San Onofre shut down [View all]
Greenhouse gas emissions from power plants in California increased by 35% in 2012, partly due to the early closure of the San Onofre nuclear power plant.
According to figures from the California Air Resources Board, carbon dioxide emissions from the state's power generation facilities increased from 30.7 million tonnes in 2011 to 41.6 million tonnes in 2012. Data shows that such emissions had been steadily declining between 2008 and 2011.

The Air Resources Board said that the increase in emissions in 2012 was "primarily due to emission increases from California electricity generation using natural gas as a fuel." This was due to a decrease in available hydroelectric generation as well as the shut down of the San Onofre nuclear plant.

As well as increasing emissions, the plant's closure has also impacted California's wholesale electricity prices. Over the first half of 2013, the US Energy Information Administration reported a 59% increase in wholesale power prices in the state, which it ascribes largely to the extended outages at the two units.
