Texas both produces and consumes more energy than any state in the U.S. It controls one-quarter of U.S. proven oil reserves. Energy companies looking to grow or to establish a U.S. presence set up operations in Texas. The primary electricity transmission system in Texas is independent of the rest of the country (a long-time source of pride). The Electric Reliability Company of Texas, or ERCOT, is responsible for regulating the generation and supply of power to 85% of the state, except the extreme eastern and western portions.
The fundamental challenge of a closed system is that it must meet its own needs, and that has not happened. There are increasing concerns about rolling blackouts in America’s “energy capital”. NRG Energy reported that by 2016, Texas could experience four rolling blackouts a year, and strongly recommended that the state build more power generation reserves to improve grid reliability.
Old and inefficient power plants are being fired back up to meet demand peaks, which is an inefficient use of inefficient technology and is unreliable. The transmission system is outdated. Financial obstacles like the bankruptcy of Energy Future Holdings (and all the associated fallout) - which controls the largest retail utility and the largest power generation fleet in the state – overhang any possible solution. All these challenges combined with growing electricity demand amount to a potentially serious problem.
