Hull Wind I

• How did it happen?

• Who will be next?

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 and 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. American Wind Energy Assoc.

Wind happens…

• In 2004, the American Wind Energy Association estimates that wind plants in the U.S. will generate 16 billion kilowatt-hours. If instead the average utility fuel mix were used to generate that much electricity, 21 billion pounds (10.6 million tons) of carbon dioxide, 56,000 tons of sulfur dioxide (150 tons per day), and 33,000 tons of nitrogen oxides (92 tons per day) would be released into the atmosphere.

Where is Hull…

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

1984-1996

• Hull installed a 40 kW Enertech machine

• $78,000.00

• Saved the town over $70,000.00 in electricity

• Decommissioned in 1996

CARE group started

• Small group of concerned citizens start Citizens for Alternative Renewable Energy in 1997 to study repowering wind turbine sited at Hull High School

• Help from UMA Renewable Energy Labs• Support of the Municipal Light Plant• Presented to Town Selectmen• Town voted in favor of the project

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 7, 2001

• 1234 days of generation

• 19837 hours

• 5,328,989 kWhs

• Capacity Factor 27.2%

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.

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.

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

Top 10 States for wind

• 1.  North Dakota 1,210 B kWh/yr• 2.  Texas 1,190 • 3. Kansas 1,070 • 4. South Dakota 1,030 • 5. Montana 1,020 • 6. Nebraska 868 • 7. Wyoming 747

• 8. Oklahoma 725 • 9. Minnesota 657 • 10. Iowa 551

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

Who will be next?

• Ipswich• Mattapoisett• Hingham• Scituate• Yarmouth• Orleans

• [Name of your town here]

• Marion• Arlington• Bourne• Marblehead• Provincetown• Quincy• Dorchester???

Hull Wind II will be next…sorry.

• The town of Hull has voted to install 1 more turbine on land.

• Sited at the town dump, a capped landfill. First of its kind in the US

• Vestas V80 1.8 MW machine selected.

• Installation could begin by end of summer.

• 3X the output of Hull Wind I

MIT Professor John Deutch

• Many experts believe that nonrenewable fuels, in particular oil and gas, will eventually become so scare 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.
