Three of California's largest utilities are collectively seeking about $ 1 billion in public funding that would be used to aggressively expand the electric-vehicle charging infrastructure throughout the most populous US state. Southern California Edison is looking to make the largest impact, having asked the state for more than $570 million — in the form of additional billings from customers — to fund charging programs and infrastructure. The utilities' funding requests are part of a broader effort for California to meet its recently updated goal to cut greenhouse-gas emissions by 40 percent between 1990 and 2030 as a way to address global warming.With transportation accounting for about 40 percent of the Golden State's greenhouse-gas emissions, the utilities are each making a case that the large sums are warranted. For Pacific Gas and Electric Co. (PG&E), that means a request to the California Public Utilities Commission (CPUC) for $253 million over five years. Meanwhile, San Diego Gas & Electric is seeking $246 million.The overall goal is to facilitate the addition of tens of thousands of plug-in vehicle chargers at homes and businesses across the state, while further spurring the adoption of electric vehicles , particularly as a replacement to gas- or diesel-powered delivery trucks or buses. As it is, California accounts for almost 12,000 of the approximately 40,000 publicly accessible plug-in charging outlets in the country, according to the US Department of Energy .

Regardless, the California government has indicated that it will operate by a set of green-transportation standards that will continue to exceed the EPA's , making it one of many areas in which state officials say they may buck the federal government's regulations.
