The low electricity prices enjoyed by most Texas consumers can’t last forever. To understand why, you need first to understand a bit about the pricing structure in the Texas electricity market.

Under the supervision of the Texas Public Utility Commission, a co-op called the Electricity Reliability Council of Texas (ERCOT) sets the structure for the Texas electricity market. For a long time, ERCOT has used a model under which companies that generate electricity are paid only for the electricity they generate.

When electricity is plentiful, competitive pressure dictates that the price a generator can charge will be little more than the cost of generation. Only during times of electricity shortage can producers charge enough to enable them to invest in new plants and equipment. When shortages are rare, as is currently the case, very little capital can be accumulated to provide the financing for future growth.

Every electricity market has its own challenges.  The situation in Texas came into stark relief when ERCOT’s independent market monitor, in its July 15, 2015, annual report on the state of the energy market in Texas, noted that electricity prices in 2014 could not have provided sufficient capital for any generating company to invest in current generating technology without losing money, or “incurring negative cash flow” in accounting terms. The report excluded any comment on wind generation, which has expanded rapidly due to federal subsidies but which faces additional costs of transmission and storage. That is, when they are needed most, wind resources are not reliably present.
