Week 3 material

New Wind farm in Pennsylvania: Built basically on top of an old coal mining ridge.

Details on the Casselman Wind Farm project in PA:

• 23 turbines @1.5 MW each: 35 MW
• Located on an Appalachian Ridge Line
• 35 MW is about 10% of the power demand for Eugene
• Average employment was 100 workers during construction
• OPM Jobs = 3
• Construction began in May 2007 - Partially on line in Feb 2008 - fully on line in Oct 2008
• Total project cost = $61 million ($1750/KW) - current wind costs vary from $1500 to $2000 per KW.
• Project services 10,000 homes.
• Supposed you meter the product at 5 cents per KWH - what is the payback time to recover $61 million?
• @1/3 efficiency timescale = 21 years
• @ 7 cents per kwh and 40% efficiency time = 12 years
• Hence, this is a sound investment.

   For each site, designated by the coordinates:

    

   a) Measure the total length of a "leg"
   b) count how many turbines there are per "leg"
   c) estimate the total number of turbines in this general area
