Implementation Background

​To help secure our energy future, the Public Utility Commission of Texas (PUCT) was charged with addressing the Competitive Renewable Energy Zones (CREZ) legislative mandate. As a result of the CREZ rule:

  • The Electric Reliability Council of Texas (ERCOT) provided a study of the wind energy production potential statewide, and of the transmission constraints most likely to limit the deliverability of wind energy resources.
  • The PUCT designated CREZs based on ERCOT’s study taking the following into consideration:
    • Whether renewable energy resources and suitable land areas were sufficient to develop generating capacity from renewable energy technologies.
    • The level of financial commitment by generators and developers.
    • Other factors considered appropriate, i.e. estimated cost of constructing necessary transmission capacity, estimated benefits of renewable energy produced in a zone.
    • The best and most cost-effective way to deliver these resources to customers.

To implement the directives of the new CREZ rule, a number of initiatives have been introduced (and completed) in various arenas.
