• Economic benefit of 1,000 MW = $1.25 billion
5,530 construction jobs, 215 permanent jobs
• Average wages in component manufacturing industry = $40,709 - 15% higher than average state wage
• Strong correlation between Western OK counties that have lost population in recent decades with counties that have significant wind resources
• In many cases, land suited for wind development has lower per-acre returns for agricultural use
• Sooner Survey of 600 registered voters:
72% of Oklahomans willing to pay more for wind-generated electricity
91% approve of further development of wind farms

Why develop new markets?
• SPP conducts complex cost-benefit studies before beginning any new market development
Under Regional State Committee oversight
2005 Charles River and Associates (CRA) analysis of the EIS market:
Estimated benefit of $86 million for first year
Actual benefit of $103 million for first year
• New markets will bring estimated average additional benefits of $100 million
According to 2009 Ventyx analysis

What type of new markets is SPP implementing?
• Day Ahead: SPP determines what generating units should run the next day for maximum cost-effectiveness
• Ancillary Services: Market to buy and sell reserve energy that:
Meets emergency needs
Regulates instantaneous load and generation changes
Maintain electricity quality (keeping voltage up, etc.)
