Solar Resource Screening Analysis
All Solar Resources
Locations Suitable forDevelopment
Start with direct normal solar resource estimates derived from 10 km satellite data.
Eliminate locations with less than 6.0 kWh/m2/day.
Exclude environmentally sensitive lands, major urban areas, and water features.
Remove land areas with greater than 1% (and 3%) average land slope.
Eliminate areas with a minimum contiguous area of less than 1 square kilometers.

Hydroelectric Power: Where It Comes From
• Flowing water has energy that can be
captured for some useful purpose
• When this energy is captured and used to
generate electricity, it is called
hydroelectric power or hydropower
• Hydropower plants use the energy of
flowing water to turn a turbine that rotates
a generator to produce electricity
• Hydrologic cycle: sun causes evaporation
from lakes and oceans, forms clouds, falls
as rain or snow, then flows back down to
the ocean, and the cycle repeats
• Hydropower is renewable because the
water cycle is an endless, constantly
recharging system
• Hydropower uses a fuel (water) that is not
consumed in the process of generating
electricity
The water (hydrologic) cycle

Hydroelectricity Physics
Power (kW) = 10 x Flow (m3/s) x Head (m) x
Power (kW) = Head (ft) x Flow (cfs) x /11.8
= turbine-generator efficiency ~80%

Potential Resources
New Conventional Hydro (low power to large hydro) = 62,300 MW
Hydrokinetic = 12,800 MW (tidal only assessed for 5 states, ocean current not assessed)
Hydro Green Energy delivered the first of two hydrokinetic turbines to Hastings, Minnesota, in early December. The barge-mounted power plant will be parked in the output of Mississippi Lock and Dam No. 2, which is visible in the background. (12/15/08)
