Yah, ok. Enough with the pep talk.
Lets see some data.
In fact, let’s check every ten seconds.
So, how about Indiana?
How about this fella with the typical house?
Now here’s a bigger home.
Proposing A Common Sense Solution
Utility Owned Thermal Grids: Grow Base Load 15% per home Proven business model with highest NPV 0% Capital is available to utilities Easements are simple Asset performs for over 100 years Utility uses On-Bill “Financing” for high ROI & recurring revenue Renewable Energy tariffs may be added to rate base in many cases Homeowner savings exceed payback for 7 year payoff Establishes long term fuel certainty for all stakeholders
Benefits of Electrification
What is Electrification?
Electrification Technologies at Duke Energy:C&I:Fork trucks, refrigeration standby units, airport ground terminal equipment, EVs, LEDs, SmartSaver, Outdoor lighting, Agricultural, Cooking, and more!
Residential:EVs, Home Energy Assessment, PowerManager, SmartSaver, LEDs, Outdoor lighting and others!
Barriers to Adoption:Infrastructure, Awareness and Cost

Electric Thermal Storage (ETS)
Electric Thermal Storage
Electricity is stored as heat in a well insulated brick core.
All heating is accomplished by using off-peak or renewable energy
Internal blower system delivers the heat to the conditioned space as needed to maintain comfort 24/7.
(Open View)
Storage occurs based on availability of renewable or off-peak energy or as signaled by the utility.
On-board Microprocessor based control system regulates charging and discharging.
