Project Fundamentals: 

Project Fundamentals Ridge Installations: What’s different?* * As compared to baseline Stakeholders All adjacent landowners (difficult to go around) Balance of Plant (~10% premium) Roads & Crane Paths Foundations Collection Grids and substations Laydown Areas Other (premium = moving target) Logistics Turbine Erections Decommissioning (bond requirements)

Evolving Solutions: 

Evolving Solutions Some cranes < 15’ wide May not require improved crane pad (outriggers)

Evolving Solutions: 

Evolving Solutions …still need a long, straight space to build the crane

Foundations: 

14 Foundations Guyed Tower Tilt-Up Tower Self-Supporting Tower Concrete = 10x (compared to P&H)
