Corporate compliance program overview
The ISO Corporate Compliance department helps the ISO exercise sound judgment, make the right choices and take the right actions. They assess, monitor and investigate ISO compliance with the NERC compliance monitoring and enforcement program, internal investigations and ISO policies, procedures and tariff.
The Compliance Committee reports directly to executive management and works independently of other business units to ensure compliance activities are free from undue influence by those with responsibilities for adherence to reliability standards and other regulatory requirements. Our board appointed Chief Compliance Officer has direct access to the CEO and Board of Governors to ensure appropriate communication of compliance concerns to the highest levels within the ISO.
As required by the Federal Power Act of 1935, the ISO operates under the terms and conditions of its FERC approved tariff, which contains the rates, terms and conditions governing all areas of the ISO business, including:
- Requirements for participating in the ISO’s energy and ancillary services markets
- Rules for determining the prices paid to providers of electricity and ancillary services and how these charges are allocated
- Transmission access charges
- The ISO’s grid management charge
- Processes for generation interconnection and transmission planning.
The ISO FERC-approved tariff is modified, amended, supplemented or restated as needed. If a provision of an existing ISO contract, business practice manual or operating procedure conflicts with it, the tariff will prevail to the extent of the inconsistency.

NERC reliability standards and registration
The Energy Policy Act of 2005 requires that FERC approve and enforce standards to protect and improve the reliability of the nation’s bulk power system. The North American Electric Reliability Corporation (NERC) develops, revises and implements standards under this statutory framework and delegates compliance monitoring and enforcement authority to various regional councils, such as the Western Electricity Coordinating Council (WECC). NERC also develops and approves regional reliability standards, which are more stringent than a continent-wide reliability standard and may address a regional difference in the bulk power system.
