Market Rules
Balanced market rules are a basic element in Texas competition. Clear, predictable and well-designed rules help foster a stable electricity market. Electric Reliability Council of Texas (ERCOT) market rules are developed by participants from all aspects of the electricity industry. The rules and amendments are reviewed by the Public Utility Commission of Texas to ensure that they satisfy the public interest.
In this section, you will find the ERCOT protocols, guides, policies and procedures that help steer the Texas market participants.
