Why Meridian Way?? Empire’s 2006 Integrated Resource Plan
(IRP) Results►Goal: 100 MW of Additional Wind Energy►Request For Proposals (RFP)
● Wind Energy Resources Post 2007● Cost Effective Pricing● Suitably Located
►What is “Suitably Located”?● Location Diversity From Existing Windfarm● Transmission Upgrades

Why Meridian Way?? (Cont’d)
RFP Evaluation►Most Economical►Ready for Construction by end of ‘08
Horizon’s Meridian Way Windfarm►“Suitable Location”
●Location Diversity: Yes●Transmission Upgrades: TBD

Can Empire Integrate More Wind into its System?
We Believe the Answer is Yes – But it Will Not Always be Easy
Empire Currently Has Two Aero-Derivative Gas Turbines Totaling 100MW►Quick Start Jet Engines►Can be Used as Backup Generation if Wind Drops
Unexpectedly All Wind PPA’s Were Evaluated in Conjunction
with another 50 MW Aero-Derivative Gas Turbine

Closing Thoughts Empire Believes in Having a Balanced Mix
of Generation Options (Don’t Put All of Your Eggs in One Basket)
Wind is an Integral Part of that Mix Additional Wind Benefits
►Hedge Against Volatile Natural Gas Prices►Future Renewable Portfolio Standard (RPS)►Carbon Regulation
