Technology
• Geothermal – reduction; heat exchange
• Solar PV – production; no fuel
• CHyP – biomass; focus on waste streams

What is a Geothermal System? The heat continuously flowing from the Earth’s interior, which travels primarily by conduction, is estimated to be equivalent to 42 million megawatts (MW) of power.
![Page 7: Snapshot of solar, horizontal geothermal & c hy p](https://reader034.vdocument.in/reader034/viewer/2022042602/55d5395ebb61eb251b8b46f6/html5/thumbnails/7.jpg)
Geothermal
• A geothermal system requires heat, permeability,
and water.
• Geothermal energy can be used for electricity
production, for commercial, industrial, and
residential direct heating purposes, and for
efficient home heating and cooling through
geothermal heat pumps.
![Page 8: Snapshot of solar, horizontal geothermal & c hy p](https://reader034.vdocument.in/reader034/viewer/2022042602/55d5395ebb61eb251b8b46f6/html5/thumbnails/8.jpg)
Geothermal
• What advantages do geothermal heat pump systems offer? – A 25 to 40 percent reduction in heating and cooling costs
– Standard, simple controls
– No need for a highly specialized chiller technician or boiler operator
– Highly durable piping (the life expectancy is between 30 and 50 years)
– No high-maintenance, freezing-prone cooling tower
– No boiler to clean or maintain
– No air conditioning equipment on roof to cause leaks
– No harmful chemicals
– No danger of fire, asphyxiation, or explosion from coal, gas, or oil
– Nothing outside to vandalize or steal
– No central system to fail or shut down the entire building.

What is a Solar System? A solar system uses the sun’s rays to produce
electricity that you sell to the electric company.

Recent historical cost
to install solar
Year Installed Cost Per Watt Installed (Av.)
2012 $3.00
2011 $3.25
2010 $4.00
2009 $6.50
2008 $10.00
The Lingo • Annual home typical usage
= 16,200 kWh
• Solar System size needed
= 11.41 kW
• Cost of system = $34,225
• Installed cost per watt =
$3.00
![Page 12: Snapshot of solar, horizontal geothermal & c hy p](https://reader034.vdocument.in/reader034/viewer/2022042602/55d5395ebb61eb251b8b46f6/html5/thumbnails/12.jpg)
More Math • Solar System size = 11.41 kW
• Annual power production =16,200 kWh
• Warranty life of the system = 25 years
• Total production over life of the system
– 25 years x 16,200 kWh = 259,200 kWh
• Total Cost of system = $34,225 (without tax incentives)
• Cost per kWh = $0.132

Power Purchase Agreements (PPA)
• TVA region works well for PPA
• A PPA is an agreement between
– Solar System owner
– Property owner
• Generally, the Solar System owner can use the
tax credit
• Property owner generally
– Lacks financing
– And/or cannot not use the tax credit

Readiness • TVA Green Power Providers program has reached the limit for
solar photovoltaic (PV) applications in 2013.
• TVA has added another 2.5 MW for 2013 and will start
accepting applications on August 1, 2013. We anticipate the
program will be exhausted that day.
• In 2012, TVA also reached the limit of applications being
accepted and approved.
