An interesting fact seemed to go unnoticed in all the press around the Electric Reliability Council of Texas’s (ERCOT) Long Term System Assessment, a biennial report submitted to the Texas Legislature on “the need for increased transmission and generation capacity throughout the state of Texas.”

ERCOT found that if you use updated wind and solar power characteristics like cost and actual output to reflect real world conditions, rather than the previously used 2006 assumed characteristics, wind and solar are more competitive than natural gas over the next 20 years.

Finally, one ERCOT statement in particular stands out from this analysis, in direct contradiction to renewable energy opponents who say that renewable energy is too expensive: “the added renewable generation in this sensitivity results in lower market prices in many hours [of the year].” This means that when real-world assumptions are used for our various sources of power, wind and solar are highly competitive with natural gas. In turn, that competition from renewables results in lower power prices and lower water use for Texas.

As state leaders look for ways to encourage new capacity in the midst of a drought, it’s important to realize that renewable energy is now competitive over the long term with conventional resources. The fact that renewable energy resources can reduce our water dependency while hedging against higher long-term prices means that however state leaders decide to address the energy crunch, renewables need to be part of the plan.
