Intro

Reliable electricity is an expectation. Every yearour economy becomes more efficient and

productive. Electricity is the fundamental building

block for those efficiencies.

August 10, 1996 blackout in the Western US States: power was interrupted to approximately 7.5 million customers,

durations ranged from a few minutes to about nine hours.

costs to the regions economy ~ $2 b i l l ion .

August 14, 2003 blackout, Midwest/Northeast US & Ontario

50 million people Up to 4 days in the US

Cost estimates range between $4 b i l l ion and $10 b i l l ion

Technical feasibility Siting- Estes Park Anemometer Results

CSU Senior Researcher Michael Kostrzewa inconjunction with the Governors Energy Office(GEO) provided data collection & analysis.

Estes Park is a number 2 wind class at60 FEET. The worst is 1. Kostrzewa/GEO results for EstesPark.

Larimer County has a 40 foot height limit! Wind power classes 3 and higher are generally

considered suitable for wind power development.

Thats not good. PRPA will deliver renewable energyfrom Duke energys Silver Sage site having 40% net

Energy storage is the enabling technology for small scalerenewable energy.

Boring but RICH ! Today, 99 percent of batteries for hybrids are made in Japan Aug 2009, the US gave out $2.4 billion in grants for advanced battery

manufacturing & research the largest battery investment in world history

Economic feasibility Revenue expectations

Colorados Net Metering legislation requires electric

utilities to rollover excess energy generated eachmonth. Great customer SAVINGS, not revenue

At the end of one year, the excess renewable energy

generated is paid to the owner IN A MANNER DEEMEDAPPROPRIATE BY THE ELECTRIC ASSOCIATION Estes Park Light & Power pays customers an Avoided

cost ~ $0.02 per kWh. Most utilities deem zero to bethe appropriate amount.
