Production

• Each Turbine will produce 150,000 KWH per year on average.

• Shallowater High School uses 1.2 million KWH per year.

• Three Turbines will produce 450,000 KWH.• Approximately 30-40% of our usage can be

covered with three turbines @ 9 cents per KWH. (a potential savings of 450,000KWH * .09 = $40,500)

Revenue

• Green Credit Production is an added benefit (possible additional revenue on sale of Green Credits) Some companies pay more for clean energy. (Whole Foods, Microsoft, Starbucks, etc.)

• On five wind turbines, we project $70,000 in savings on our energy costs and a possible Green Credit sale of $25,000

District Cost Benefit

• Using EDA money from state makes SISD’s share of the cost at 30%.

• Total cost for the project was $700,000• SISD’s share of the cost was $210,000• With $70,000 a year savings, the district will

pay our share in 3 years on a turbine that has a 30 year life. Over the span of 27 years, the district will save $1,890,000 in electrical costs.

Wind is “Good Business”

• Net metering – Gaining credit for production at the meter.

• The produced electricity is taking the place of energy at retail cost

• Excess production is stored in the local grid and used over a period of a month

• Production of the electricity is for your own use and not for wholesale production

• Wholesale production on this scale would not be cost effective

• These machines are about 1/12 to 1/24 the size of the 600KWH and 1.2 MWH machines.

Challenges

• Community Awareness

• Noise

• Distance to Residential Areas
