Regulatory Filings

By law, we must publish rate changes and formal cases made to agencies to inform customers. These pricing changes must be approved by your state’s energy agency (Public Utilities Commission of Texas) before they take effect.

You'll find rate case filings in Regulatory Filings, resource plans in Resource Plans and transmission filings in Transmission.

Our products and services differ based on state. Please select your state (or the state you're interested in) from the list to the left.

Why do our products and services differ based on state? Because our business is regulated by state. We have regulated operations in eight Western and Midwestern states. The different regulatory body for each state we serve determines what products and services we deliver in that state.
