TVA Electricity Label, May 2001

 

 

This electricity label is intended to provide you with information about the energy resources and selected environmental impacts of generating and using electricity. Like food nutrition labels, electricity labels can help you choose between electricity supply options, as with our renewable energy Green Power Switch. Green Power Switch is a TVA electricity product accredited by the Center for Resource Solutions. The distribution of the electricity label is a requirement of accreditation.

 

You have a choice when you buy electricity. You can choose to buy blocks of power from Green Power Switch or use electricity generated by the traditional methods listed below. The following labels compare the power content and air emissions of each of these products.

 

 

 

Standard Power Content

In 2000, TVA used the following resources to generate standard electricity:

SYSTEM RESOURCES

PERCENT SUPPLY

Fossil fuels

63%

Nuclear

31%

Hydro

6%

TOTAL

100%

 

 

Standard Air Emissions

Electricity provided to you in 2000 created the following emissions:

EMISSIONS

AMOUNT

Sulfur Dioxide (SO2)

9.5 lbs/MWh

Nitrogen Oxides (NOX)

3.7 lbs/MWh

Carbon Dioxide (CO2)

1414 lbs/MWh

MWh = megawatt-hour, or 1,000 kilowatt-hours.

Green Power Switch Power Content

In 2000, solar and wind generating facilities began operation as part of Green Power Switch.  Landfill gas energy that was expected to begin generating was delayed and will become operational in May 2001.  As of May 2001, each block of Green Power Switch will represent the following resources*: 

ENERGY RESOURCES

AMOUNT

Renewable Resources

150 kWh/month

- Landfill Gas**

116 kWh

- Wind

32 kWh

- Solar

2 kWh

 

*People living in our area use an average of 1250 kWh of electricity per month. You may buy as many blocks of Green Power Switch as you want. The remainder comes from standard system power shown at left.

 

**In addition to adding landfill gas energy, TVA plans to  expand the proportion of wind in the Green Power Switch power content  in 2003 or 2004.

 

Green Power Switch

 Air Emissions

With the addition of landfill gas energy to Green Power Switch’s resources, as of May 2001 electricity from a block of Green Power Switch will create the following emissions*:

EMISSIONS

AMOUNT

Sulfur Dioxide (SO2)

0.1 lbs/MWh

Nitrogen Oxides (NOX)

3.0 lbs/MWh

Carbon Dioxide (CO2)

0 lbs/MWh

MWh = megawatt-hour, or 1,000 kilowatt-hours.

 

*These emissions are from landfill gas, which would have had CO2 emissions and some NOx emissions even if the gas had been burned without generating electricity.

 

The remainder of your electricity created the same emissions as standard system power shown at left.
