ISO-NE Load Forecast Methodology

This presentation indicates that for New England the increasing demand for summer-time electricity is greater and increasing faster than winter-time demand. The fast-rising need for power in summer will likely result in construction of new power plants to keep ahead of demand - although inland industrial wind plants will not be able to contribute much to this demand period due to their very low capacity factor during summer months.

2004 Vermont Comprehensive Energy And Electric Plan

2004_final_draft_elec_energy_plan_thumb "The biggest blackout in history on August 14, 2003 brought all economic activity in the northeastern United States to a halt. At 4:11pm EST, the sudden plunge into darkness was a reminder of just how much we depend on energy for much of our activities. Thirty years earlier, another energy shock – the 1973 OPEC oil embargo – provided a more protracted lesson in the importance of energy to our overall well-being. The recommendations in this Plan all stem from the fundamental importance of energy to the State’s economy and the well-being of its citizens. Because energy – especially electricity – remains a fundamental driver of the VT economy, competitively priced energy continues to be vital, since differentials in energy costs can be a determinant in relative competitiveness of one region over another. The disparity between the average electric rates Vermont’s residential and business customers pay, and the average rates paid by customers in the U.S. as a whole, has steadily increased. In 1990, Vermont’s residential electric rates were about 15 percent higher than the U.S. average, commercial rates were about 20 percent higher, and industrial rates were some 35 percent higher than the U.S. average. Today, that disparity has grown to about 50 percent for all three classes"....

Comments pertaining to the accuracy and completeness of the Kittitas Valley Wind farm Project DEIS

Efsecdeis-robertsontestimony_thumb This document [DEIS] has not provided any demonstrable public need for the insignificant amount of power this facility is capable of producing. No valid, compelling local (or even statewide) economic reasons were offered to potentially offset the overwhelming negative impacts that will result if built. This DEIS is abundant in quantity, but extremely lacking in quality of scientific analysis and entirely deficient in analysis in certain areas. Various mitigations offered are unacceptable or unworkable. The following are areas of analysis that were either deficient or not performed at all:............

Windfarms- an ecological and human disaster in the making

A CASE IN POINT: THE VALENCIAN WINDPOWER PLAN "The Valencian windpower plan ("Plan Eólico") was approved July 26th, 2001. It calls for the implantation of 2700 wind turbines in the Comunidad Valenciana, many of them in the mountains of the Costa Blanca. After two years of negotiations behind closed doors, the pieces of the subsidized pie have been allocated. Soon the bulldozers will start destroying the ultimate asset of this region: its unspoiled interior. See the narrow valleys, smell the orange blossom, marvel at the olive groves: they will never be the same. Neither will the craggy mountains, warm shades of amber in the winter sun. All of this will go, marred by industrial structures. The almond trees will bloom under ugly pylons, and we´ll view the cherry blossoms against a backdrop of rotors and power lines."

Best Practices - Wind Energy Siting Guidelines

This letter, written by Tom Hewson, responds to a New York State resident who had inquired about the impact of industrial wind turbines on property values. The letter specifically critiques the REPP study. It provides as well an overview of other studies that existed as of Fall 2003. "The issue simply comes down to nuisance and aesthetics. If the project creates a nuisance (noise, shadow flicker, TV/cell phone interference, radar interference), it can cause lower property values to adversely affected areas. People can simply apply their own personal evaluation criteria to determine the extent of the property change. What would it be worth to you? Generally, the bigger the nuisance, the larger the devaluation. Localities can minimize nuisances from wind projects by setting minimum setbacks, proper location siting and noise limits. My concern with the REPP study is that it doesn't try to examine the nuisance effect by selecting a large 5 mile area."

correspondence on Bat Kill re. Meyersdale Windplant

Gannon_usfws_letters_1__thumb Dear Mr. Boone: I am in receipt of the information you sent regarding the Meyersdale wind project and the risk to bats, specifically Indiana bats in that area and your request for my opinion on this project. I have also done some research on my own concerning wind turbines and its affects on bats, to determine what data are available in the scientific literature in this area. I base this opinion on data and scientific literature, and my 16 years experience studying bat biology and bat ecology.

Blowing in the Wind: Offshore Wind and the Cape Cod Economy

Written by Jonathan Haughton, Douglas Giuffre and John Barrett, this report addresses the prospective impact on the Cape Cod economy of 130 wind turbines in Nantucket Sound. The study includes the responses of tourists and residents to the aesthetics of the proposed project as well as the result of a survey among tourists on the degree to which the project would influence their desire to visit the area. The authors conclude that 'caution' is in order. A follow-up study entitled "Free but Costly" An Economic Analysis of a Wind Farm in Nantucket Sound" was published in March 2004.

California ISO Five Year Assessment (2004-2008)

An excerot of the report discussing the limitations of wind is provided below. The full report can be accessed by clicking the links on the page.

Inquiry Into The Practicalities of Developing Renewable Energy

Practicalities_of_developing_renewable_energy_thumb The random intermittency of electrical power supplied from many renewable sources, most notably wind, requires a high level of conventional back-up generating capacity to ensure security of supply. As the penetration of intermittent generators increases and becomes a significant proportion of the total, the extra system requirements and costs could pose serious problems. Although the causes of recent well-publicised blackouts have been due to other reasons, intermittency will exacerbate the potential for cascade failure. Editor's Note This paper complements the Irish Grid and Eon Netz reports that address the low capacity credit of wind power.

Effects of the wind profile at night on wind turbine sound

Gpvandenberg_thumb This significant research by van den Berg explains why turbine noise as far away as 1900 meters (more than 6,000 feet) is resulting in complaints by residents particularly at night. The paper concludes that noise immission predictions are not accurate and result in the understating of turbine noise levels, particularly during nighttime conditions.

Effects of the wind profile at night on wind turbine sound

Effects_of_wind_profile_at_night_on_wind_turbine_sound_thumb Journal of Sound and Vibration "Since the start of the operation of a 30MW, 17 turbine wind park, residents living 500m and more from the park have reacted strongly to the noise; residents up to 1900m distance expressed annoyance. To assess actual sound immission, long term measurements (a total of over 400 night hours in 4 months) have been performed at 400 and 1500m from the park. In the original sound assessment a fixed relation between wind speed at reference height (10 m) and hub height (98 m) had been used. However, measurements show that the wind speed at hub height at night is up to 2.6 times higher than expected, causing a higher rotational speed of the wind turbines and consequentially up to 15 dB higher sound levels, relative to the same reference wind speed in daytime. Moreover, especially at high rotational speeds the turbines produce a ‘thumping’, impulsive sound, increasing annoyance further. It is concluded that prediction of noise immission at night from (tall) wind turbines is underestimated when measurement data are used (implicitly) assuming a wind profile valid in daytime."
