Presentation on the first Urban sited, Industrial sized Wind Turbine in the United States

Why Wind?• Development of just 10% of the wind potential in the

10 windiest U.S. states would:• Provide more than enough energy to displace

emissions from the nation's coal-fired power plants.• Eliminate:

– the nation's major source of acid rain; – reduce total U.S. emissions of CO2 by almost a third; – and help contain the spread of asthma and other respiratory

diseases aggravated or caused by air pollution in this country.

Top 10 States for wind

1. North Dakota 1,210 Billion kWh/yr2. Texas 1,190 3. Kansas 1,070 4. South Dakota 1,030 5. Montana 1,020 6. Nebraska 868 7. Wyoming 7478. Oklahoma 725 9. Minnesota 657 10. Iowa 551

Wind power in Hull, MA• Wind used as far back as 1820 by Henry

Tudor who pumped seawater into wooden vats, allowed it to freeze and harvested the salt

Wind Works…• In 2004, the AWEA estimated that wind plants in

the U.S. generated 16 billion kilowatt-hours.

• If instead, the average utility fuel mix were used to generate that much electricity,

– 10.6 million tons of CO2– 56,000 tons of sulfur dioxide– 33,000 tons of nitrogen oxides would be released into the atmosphere.

American Wind Energy Association

How much energy can wind supply to the U.S.?

• Wind energy could supply about 20% of the nation's electricity.

• Wind energy resources useful for generating electricity can be found in nearly every state.

• North Dakota is theoretically capable (if there were enough transmission) of producing enough wind-generated power to meet more than one-third of U.S. electricity demand.

C.A.R.E. group started

• Small group of concerned citizens start Citizen Advocates for Renewable Energy in 1998

• A study of repowering wind turbine site at Hull High School

• Presented to Town Selectmen• Public forum in June 2000 added strong

support• Spring 2005 I-CARE formed in Ipswich after

public meeting there with CARE speakers

Vestas V-47 Turbine• Danish manufacturer Vestas was selected

• V-47 machine – 660 kW $700,000.00

• 50 m tower 75’ blades 28.5 rpm

Production to date• Commissioned on December 27, 2001

• 1293 days of generation 20710 hrs (net)

• 5,502,674 kWhs

It looks like this from the air

Where is Hull…

Hull Wind II comes next…

• The town of Hull voted (Oct 2004) to install 1 more turbine on land.

• Sited at the town dump, a capped landfill. First of this landfill siting in the U.S.

• Vestas V80 1.8 MW machine selected.

• Installation could begin by end of summer.

• 2.7 X the output of Hull Wind I

1984-1996

• Hull installed a 40 kW Enertech machine

• $78,000.00

• Saved the town over $70,000.00 in electricity

• Decommissioned in 1996

Hole for the foundation is dug

Financials

• Turbine cost: $700,000.00

• Over 20 years $35,000.00

• Maintenance/Warranty $ 8,000.00

• Insurance $ 8,000.00

• Total Year Fixed price $51,000.00

• $51,000.00 / 1,500,000 kWhs= $0.034

• 3.4 cents / kWh

Financials

• Credits– RECs $0.030/kWh– REPIs $0.018/kWh

• $0.048/kWh

Financials

• Hull generates revenue from the turbine:

• $0.048/kWh - $0.034/kWh = $ 0.014/kWh

• Annual Savings– 1,500,000 kWhs X $0.08/kWh = $120,000.00– 1,500,000 kWhs X $0.014/kWh = $21,000.00

OVER $140,000.00 savings per year over 20 years or over $3,000,000.00 for the town.

Additional incentives

• Federal Level:

PTC Production Tax Credit

or

REPI Renewable Energy Production Incentive

1.5 cents/kWh adjusted to 1.8 cents

Additional incentives

• Green Certificates or RECs price varies

• MassEnergy purchases RECs from Hull at 3 cents kWh or $30.00 MWh.

Awards

• EPA Environmental Merit

• DOE Award

Awards

• Clean Air Cool Planet 2003 Climate Champions Award 2003

• Mass Municipal Association 2003 Utility Leadership Award

MIT Professor John Deutch

• Many experts believe that nonrenewable fuels, in particular oil and gas, will eventually become so scarce and therefore so expensive that they will no longer be practical largescale energy sources. Moreover, the use of coal and other fossil fuels imposes major enevironmental burdens. Therefore it is prudent to develop energy techologies based on renewable energy sources and introduce them commercially if and when the become economically competitive.

Steps to your own wind turbine

• Local Champions

• Select a site, preferably on town owned land– Near transmission lines - clearings, ridges,

away from structures

• Commission a wind study, usually 1 year.

• Work with town officials

• Identify a utility load that can be offset
