If you currently use ETS (Electric Thermal Storage) heating, and plan to switch partially or fully to heat pump heating, you will want to choose among the following electric panel configuration/electric rate options:

• If you wish to continue using ETS heating on the ETS rate, you must ensure that the breaker for your new heat pump system is not installed in the electric panel that feeds your ETS equipment.
• You can place the heat pump breaker in your ETS electric panel and continue using your ETS heating system, but it will no longer qualify for the ETS rate. CMLP will remove the ETS switch, and update the meter serving that panel to the appropriate Time-of-Day or Opt-Out residential electricity rate, which will apply to both your ETS system and your heat pump. You must notify Customer Service (concordutilities@concordma.gov), so that the ETS switch can be removed, and the meter re-programmed to bill electricity usage at the appropriate residential rate.
• If you plan to stop using ETS heating altogether, you may repurpose the electric panel feeding your ETS equipment to supply electricity to your heat pump system instead. However, you must notify Customer Service (concordutilities@concordma.gov), so that the ETS switch can be removed and the meter reprogrammed. 

You are not required to choose one of these options in order to be eligible for a rebate. The information above is provided so that you may make an informed choice among your electric panel configuration and electric rate options.
