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 whose power is proved by municipally-owned utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
Since 1996, when the energy market was opened up to competition, UK consumers have been able to switch energy suppliers to find a cheaper gas and electricity deal. Previously, Ofgem did set a maximum price for energy; but now Ofgem only regulates the market as a whole — that means creating a regulating schemes to support vulnerable households and more.
Technology that now allows smaller quantities of power to be generated closer to the end-users at prices not too much higher than grid-based power are undermining those economies of scale. More efficient turbines, for example, allow large power users like cement plants and petrochemical factories to come off the grid. Today the limiting factor for large companies to come off the grid often isn’t the efficiency of the power generation technology, but the lack of easy availability of fuel, such as gas or coal to power these turbines Even this problem is being solved by innovations like mini-liquefied natural gas projects.
