Thermal Energy Storage
Our Thermal Energy Storage (TES) rebate program is designed to help commercial and industrial customers reduce cooling costs by shifting designated load from on-peak to non-peak hours. Both new and existing construction projects qualify for this rebate.
How the program works
To qualify for the rebate, customers must shift all or part of their designated HVAC load from on-peak during the summer hours between 3 p.m. to 7 p.m. to non-peak hours, Monday through Friday. The TES system must achieve at least 100-kilowatt (kW) of demand reduction during Tampa Electric's designated peak summer hours.
Tampa Electric will require access to your facility to install an interval data recording meter, or sub meter on individual equipment for a period of twelve months or longer. Our metering devices are used to record and monitor on- and off-peak energy use.
Equipment must be new and meet or exceed the Florida Energy Efficiency Building Code. Refurbished and preexisting equipment does not qualify. Customers seeking eligibility for this program cannot be participating in any Tampa Electric peak shaving programs such as Standby Generator, Demand Response and Load Management.
Earn a rebate of $200 per kW when you install an off-peak air conditioning system that shifts (or transfers) load during Tampa Electric's peak hour of 5 p.m., Monday through Friday.
Qualifying systems will receive 50 percent of the eligible rebate upon successful installation and completion of a field verification. The remaining portion of the rebate will be paid once the TES system has demonstrated at least 90 days of successful summer operation. The total rebate paid will be based upon eligibility and the performance of the TES system.
Pre-approval is required
An approved proposal must be submitted to Tampa Electric prior to installing a TES at your facility. The proposal must contain a professionally sealed engineering analysis with demand and energy calculations, and cooling and heating load calculations.
Acquiring your rebate
