San Diego Gas and Electric, a subsidiary of Sempra Energy, is one of California’s three big shareholder-owned utilities, along with Pacific Gas and Electric and Southern California Edison. Together they serve about 70 percent of California’s electricity customers and have been raising concerns about the impact of government-run utility programs on their businesses.
Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
Variable Rate: With a variable rate, you stand closer to the fire. Rather than keep your costs separate from market conditions, you experience the rise and fall of price alongside your provider. You profit when supply exceeds demand, but could pay through the nose if the electricity grid becomes overtaxed. That usually means a higher bill in the summer and winter (when demand is at its highest) and a lower one in the fall and spring. A variable rate plan is best for people interested in staying on top of market changes – when prices get too exorbitant, there’s no contract and no cancellation fee if you want to try a new provider.
An additional bill was passed in 1999 that helped further establish a competitive electricity market by creating a price floor to prevent established energy providers from underselling emerging providers. In 2002, Texas finalized deregulation when the Public Utility Commission gave ERCOT the responsibility of managing and monitoring the Texas electricity market. The market opened up to around 6 million Texas power customers.
