Readiness

• Evaluate

• Reduce

• Produce

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.

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.

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

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.
