14. Installed Renewables-Oct 2016
80 MW Intermittent Power addition in 2016
• 24 MW Wind Power in May 2016
• 36 MW Wind Power in June 2016
• 20 MW Solar Power in May 2016
Total
• Installed Hydro Capacity - 29.12 MW
• Installed Wind Capacity - 101.3 MW
• Installed Solar Capacity - 20 MW
• Roof Top Solar - 4MW (estimated 30MW)
15. The Renewable Energy Capacity Penetration
Total Capacity = 1,024 MW
Existing RE capacity =150MW or 14.6%
VRR (Wind + Solar) = 120MW or 11.8%
Projected RE Capacity = 17.7%
VRR (Wind + Solar ) = 14.5%
Research indicates that in most large scale grid systems, VRR < 10% of peak capacity has little impact on system
operation. Larger Shares will present challenges for System Operators.
