Program basics

Three easy steps to receive a rebate

1. Purchase and install qualifying new natural gas equipment at a location with natural gas service from CenterPoint Energy in Oklahoma. Account number must be activated for installation address in order for rebate to be processed.

2. Complete the rebate form with your contactor or installer.

3. Submit the rebate form with a copy of the invoice to:
