Wind Turbines How big are they?

Tower - 80 meters (about 25 stories) at the hub

Blades – 38 meters (about 100 feet) long

How are they put together Concrete footing poured Three tower pieces assembled in

place Three blades attached to the hub

and lifted into place How fast do they turn?

16 RPM (one rotation every four seconds)

Invenergy

Land Use Wind farms and agriculture are very compatible

Wind farms require from 50 – 100 acres per turbine, with a typical wind farm comprising of 100 turbines

When completed, each turbine only removes 0.25 acres from production

Hosting a wind farm greatly benefits the community Tax base increased by ~ $2.5 MM per turbine Affected landowners receive compensation through

easement and waiver agreements

Invenergy

Interconnection Agreement The interconnection agreement allows for the generator

to interconnect to the electric transmission system This process is one of the most time consuming steps of

the development process:

In recent experience, neither PJM nor MISO has been able to adhere to these timelines

Step MISO PJ M Feasibility Study 150 days 240 days System Impact Study 148 days 120 days Facility Study 175 days 120 days* Interconnection Agreement 210 days 30 days Commercial Operation 365 days* 365 days* Total Time (days) 1048 days 875 days * Timeline not limited in tariff

Marketing the Energy and RECs

How wind energy and RECs are sold varies by market In less actively traded markets, energy and RECs are

sold under long term contracts to load serving utilities Contracts typically 20 – 25 years long Pricing fixed for the term Common in CO and WI

In more actively traded markets, energy and RECs are often sold separately Energy sold into power pool Energy price risk managed through commodity risk

managers, typically for 10 years RECs sold to load serving entities Common in TX and PJM

Invenergy

Impact of HB 1871 On May 3rd, the IL House passed a bill providing for a

renewable portfolio standard (RPS) for IL Sets a requirement that 25% of IL’s energy requirements

are met by renewables by 2025, with implementation beginning in 2007

Requires in state generation through 2011 Protects ratepayers through caps on rate impacts

Clear ratemaking requirements will be critical to its implementation Provides for 20 year power purchase agreements Provides for the Commission to review and approve

solicitation processes

Summary Wind energy can contribute significantly to serving

Illinois’ energy supply needs going forward

HR 1871 sets a high, but attainable, goal for renewables in IL, and wind will play a leading role in meeting it

In order to meet that goal, developers, ISO’s, landowners, utilities, and those that oversee them will have to work together
