Performance and Siting Advantages

Conventional Turbines FloDesign TurbinesFloDesign TurbinesConventional Turbines

Cost/Performance: ≥50% increase in capacity factor ≈50% lower lifetime O&M costs Less turbulent = closer spacing = smaller

overall project land footprint Continuing access to 30% federal ITC

Siting and Environmental: Quiet operation Visible to wildlife Much lower hub height (< FAA 200’ limit) Modular – simpler delivery logistics

The Benefits

And Lower LCOE

5 CONFIDENTIAL |

• Repowering of aging legacy California wind turbine fields

• Wholesale Distributed Wind (WDW) – organic, medium-voltage “infill” projects that do not require major grid upgrades

• Siting-sensitive areas where conventional turbines face hurdles

• Retail self-generation: a very large future market opportunity

Targeted Applications

Wind Energy and Tomorrow’s Distributed, Clean Grid

80% CO2 reduction by 2050 will require decades of rapid RE development

There’s no “magic bullet” / single solution – a highly reliable, renewables-based grid will require diverse technologies at well-distributed locations!

Wind, solar are complements not competitors, both diurnally and seasonally. Both are needed – and the more we add one of one, the more we can add of the other – taking RE from a niche role to the “tipping point” and beyond

But conventional wind energy approaches (e.g., ever-larger turbine rotors) are hitting limits of logistics, transmission capacity, siting and public acceptance

FDWT’s high performance, low profile and cost-competitive economics offer a new solution – enabling RE development much closer to customer load and maximizing wind energy’s contribution to the clean energy future we need!
