1800 SE 14 th Street - Newton, Kansas Dale Jones

Enertech History  Incorporated in 1975 in Vermont  Quickly became the premier manufacturer of home systems (1.5kw to 4 kw) Enertech 1500 tested atop Mt. Washington in mid 1970’s

 Increased size to 40kw  Installation in many California wind farms in the 1980’s  Kansas installations included St. Mary’s Of The Plains in Dodge City, and at Lake Wilson for Corps of Engineers

There are still 200 Enertech 44 series turbines operating in California wind farms over 25 years later

Who’s the young guy? Dale Jones with turbine blades in 1982

Today’s Situation  Privately-held corporation (Kansas HQ)  We produce new wind turbines from 5kw to 600kw  Dealers in USA, Canada, Mexico, England, Turkey, Vietnam, Chile, Italy, Egypt, Jordan,

Markets  Shopping Centers  Hospitals  Schools & Universities  Factories  Governmental Facilities including Military  Office Buildings  Irrigation Wells  Oil Refineries  Chemical Plants  Agri-Business including livestock feeding operations  Ethanol and Bio-Diesel plants  Dairies  Packing Plants  Community Wind Projects, including Municipal Utilities  Wind farms under 30mW in size

Refurbished Turbines Remanufactured turbine near Liberal, KS We offer remanufactured turbines from 40kw to 250kw on a limited basis

New Enertech Turbines:  E6 (5kw) –6.4m rotor diameter (21 ft) –Single phase output  E10 (25kw) –10m rotor diameter (34 ft) –Single phase output  E12 (40kw) –12m rotor diameter (40 ft) –Three phase output Above: experimental blade spoiler developed in partnership with Wichita area aircraft companies.

Small Turbine Keys to Success (100kw or less)  Good wind resource  Relaxed zoning requirements  Rising electrical rates (or even gas/propane)  Equitable net-metering  Tax incentives (Federal and/or State levels)

New E10 Wind Turbine  25kw rated output  10 meter rotor diameter  Single phase output  Motorized upwind yaw  Ideal for large residential, or farm use

Enertech ® Cyclodial Drive™ Technology Used on smaller Enertech models Patented epicycloidal design Only 3 moving parts Gearless transmission Exceptional life Low maintenance Extremely quiet operation All contact points operate in compression rather than shear

Blades built using Resin Transfer Molding Process

Enertech E48  600kw rating –Same size as Gray Co. wind farm  Technology developed in Europe  In operation for ten years  Approx units installed  Large 48 meter diameter rotor for production

E48 Component Layout

The E48 features full blade pitch control for optimum performance and safety Controls are contained inside the lower tower section

Escalating Costs 2007: $ 800, : $1,200,000 Steel/Copper Prices Freight Costs Vendor Backlog Dollar vs. Euro exchange

New E50 Turbine  Total Enertech design  50 meter rotor diameter  Dual 200kw/750kw rating  Assembled in USA  No market limitation: Large export market

Blades built here….. Eliminates ocean freight cost Lowers overall cost of turbine Eliminates import duties Enertech has more control on delivery Creates Kansas jobs

E50 Development Steps

The new E50 will have full GL certification when development is complete

The E50 is ideal for small, Community Wind Projects Markets

Future Expansion & Growth  Present facility is not large enough. Choices include: –Expand present building –Use multiple locations –Use more outside vendors –Relocate everything to another location

Need for talented people  Enertech’s growth will require additional staff & jobs: –Engineers –Technicians –Assemblers –Manufacturing –Administration –Marketing/Sales

Everyone loves wind…..  Aggressive recruitment from other states –Wind manufacturing sought out for economic development  Turbines  Towers  Blades  Castings  Machine Shops  Electronics  Many state incentives for wind manufacturers  Tax incentives  Worker training  Incentives, taxes, location and people are key

Summary  Enertech name associated with wind energy for 30 years  Enertech is focused on a specific size range, with specific target markets  Presently refurbishing 250kw turbines in Newton, KS  Introducing new 5kw, 25kw and 40kw turbines  Plan to replace current 600kw turbine with new 750kw turbine in 2009  Large global demand for sub-mW turbines in Community Wind projects  Growth will require expanded, additional or other new facilities  Growth will require expansion of labor including assembly, blade fabrication, technical support, engineering and administration
