Compliance Services

The Compliance Services Department supports MISO’s commitment to maintain reliable, compliant, efficient operations.  We collaborate with stakeholders and regulators to ensure a compliance framework that provides recognizable value to our stakeholders.  MISO employees participate in annual compliance education and every contracted party is provided a copy of the “Contractor Handbook” which explains MISO’s expectation of compliance with all applicable laws, rules and regulations and describes the procedure for reporting possible compliance violations.

At MISO, we strive to positively influence the industry on compliance and standards and improve compliance culture both inside and outside of our organization.
