California is in the process of implementing a broad portfolio of policies and regulations aimed at reducing greenhouse gas emissions. This paper summarizes the initiatives likely to impact the electricity generating sector. We present calculations showing that there is a substantial risk that two of the most prominent policies could simply result in a reshuffling, on paper, of the electricity generating resources within the West that are dedicated to serving California. This reshuffling is different from the conventional leakage problem as it involves no physical changes to the way electricity is generated across regulated and unregulated regions, but is instead driven by a contractual reshuffling of who buys power from whom. The problem is similar to an ineffective consumer boycott. The problem is still present but less severe if more Western states adopt carbon limitations. We also show that some of the least market-based initiatives, the renewable portfolio standards (RPS), are likely to have the biggest near-term impact on the carbon-intensity of electricity generation in the West. Thus the scale of RPS programs may be limiting the potential role of non-renewable options in reducing carbon emissions from the electricity sector.

Almost a fifth of the electricity produced annually in Denmark is generated by wind, yet only about 6% of the country’s electricity demand is satisfied directly from this source. Possibly two-thirds of its wind power output cannot be used to satisfy domestic needs at the moment of generation, and has to be exported (often at reduced prices) to preserve the integrity of the grid. Savings in carbon emissions are minimal. Public opposition and reduced subsidies have halted the deployment of on-shore wind turbines for the time being, but political and commercial interests are pressing to integrate much larger amounts of wind power into radically altered domestic and international transmission systems.

The Role of Wind Energy in a Power Supply Portfolio

....Wind is primarily an energy resource that makes relatively little contribution to meeting system peak loads. Even with large amounts of wind, the Northwest will still need to build other generating resources to meet growing peak load requirements.......But wind energy cannot provide reliable electric service on its own.
When wind energy is added to a utility system, its natural variability and uncertainty is combined with the natural variability and uncertainty of loads. This increases the need for flexible resources such as hydro, gas-fired power plants, or dispatchable loads to maintain utility system balance and reliability across several different timescales. The demand for this flexibility increases with the amount of wind in the system.

For those who think developers' feverish promotion of wind energy is about saving the planet, think again. The old adage follow the money explains their zeal much more than do its purported benefits. Worse, the enormous investment returns available to wind developers for an unreliable energy source that offers negligible emissions benefits stem largely from federal and state subsidies paid for by taxpayers and rate payers. Go figure.

Why did you petition to become an intervenor in this matter before the NH SEC?

With New Hampshire’s recent reinstatement of PILOT agreements and legislative efforts to a Renewable Portfolio Standard, the regulatory groundwork is being laid for more wind facilities to enter the state. Yet, New Hampshire, like many states, has no consistent regulatory process in place for reviewing these projects to ensure our environmental, societal, and economic interests are protected. The work the NH SEC has agreed to undertake in reviewing this application is precedent setting. How the committee approaches its review and the weight it places on arguments presented by all sides will impact other developments in the State as pertains to renewable energy projects.

There are a multitude of conflicting issues at play when considering any wind project. My commitment to this process is to help provide, to the best of my ability, valuable and timely information that will assist the Committee in making an informed decision on this application.

The objective of this study is to assess the costs that could be incurred by Idaho Power in modifying its operations at the Hells Canyon Complex for “integrating” or incorporating wind energy onto its system.

The intermittent and unpredictable nature of wind generation requires a utility to have generating resources available which can increase or decrease generation on short notice in order to keep the interconnected power system balanced. While hydroelectric power plants are well suited for performing this function, there are operational impacts and costs associated with operating Idaho Power hydroelectric plants in a manner that maintains reliability and facilitates integration of energy from wind generation facilities.

The issues surrounding the integration of wind generation on interconnected power systems are numerous and complex. This study provides a first step toward understanding those issues.

The latest annual energy forecast issued by the US Energy Information Administration (EIA) indicates that, by the year 2030, wind energy would supply less than 1% of US electric generation and about 4/10 of 1% of total US energy consumption.
This forecast, which likely overstates the potential contribution of wind energy, helps show that officials of the wind industry and US Department of Energy are misleading the public, media and government officials with their claims that wind might supply 20% of US electricity.

Last December some electrical power generation information for the Wonthaggi wind farm came my way. The information provides the power produced, or used, each hour for each of the 6 turbines between 1 June 06 and 22 June 06. Although it is for a limited period it illustrates, particularly when graphed, where the problem lies with wind power. That is, because it is dependent on wind availability and strength, the power produced is variable and unpredictable, requiring that some other electric power source be available at short notice to supplement what a wind farm produces.
