Hull Wind I

Brief overview of wind power in the U.S. Hull’s success Future projects Awards Questions 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. American Wind Energy Association

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

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 V MW machine selected. Installation could begin by end of summer. 2.7 X the output of Hull Wind I

Hull installed a 40 kW Enertech machine $78, Saved the town over $70, in electricity Decommissioned in 1996

Financials Turbine cost: $700, Over 20 years $35, Maintenance/Warranty $ 8, Insurance $ 8, Total Year Fixed price $51, $51, / 1,500,000 kWhs= $ 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, –1,500,000 kWhs X $0.014/kWh = $21, OVER $140, savings per year over 20 years or over $3,000, 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.

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
