Hydropower Program Near Future Challenges
• Sustaining an aging infrastructure reliably with constrained budgets; Average age – 48 years • Implementation of a sound asset management strategy • Maintaining an adequate technical workforce • Meeting new NERC electric reliability compliance standards • Declining performance metrics
- Forced outages twice industry standards - Peak unit availability 8 to 10 percent below industry standards
