As national benchmark spot prices in natural gas have risen modestly with temperatures increases and electricity demand ramping up, prices in California continue to face pressures and remain low.

With California’s mandate on renewables that 33% of its power sources must come from sources such as solar and wind energy by 2020 and 50% must be derived by 2030, natural gas prices will encounter more headwinds, said Bruce Bullock, director of the Maguire Energy Institute at Southern Methodist University's Cox School of Business in Dallas.
