• Leverage corporate-wide knowledge base– Efficiencies
– Cost reduction
• Monitor critical parameters in real-time
• Uses advanced technology to detect and prevent failure
• Interface with system operators
FPL Energy uses a state-of-the-art central monitoring center to ensure reliable wind facility operations

• Nameplate capacity (MW): full power output
• Net capacity factor (NCF): ratio of electric energy generated in a given period to the maximum possible– Wind resource is the key component
– Kansas has excellent wind resource
– Current turbine technology produces 35-45% NCF in Kansas
Net capacity factor is an indicator of wind resource
Kansas has excellent wind resource

• Market structure
• Transmission system capability
• Ancillary services and cost allocation
• Wind forecasting
System balancing authorities are able to integrate wind, accommodate its variable nature and reduce costs
Average wind integration costs are below $10/MWh

Current SPP Market
SPP expects to transition to a nodal market by 2012
To grow wind investment in Kansas, SPP market rule reform is needed
*Source: SPP Strategic Plan; Oct 24, 2006
• Bilateral
• SPP ancillary service market needs reform to be wind-friendly
• Transmission infrastructure necessary
10
• Implement nodal market structure
• Ensure wind facilities can interconnect to system
• Provide transmission capability to transfer wind power from best wind resource areas to load
• Enable wind power grid integration through ancillary service reform
• Encourage SPP best practices wind forecasting capability
Substational new wind development in SPP requires market changes
New wind development is heavily dependent on the evolution of the SPP market and transmission system expansion
