How less became more: Wind, power and unintended consequences in the Colorado energy market

This new report from Colorado's natural gas industry says increased use of wind energy indirectly results in raised pollution levels produced by some coal-fired power plants along the Front Range. The report recommends curbing the use of wind energy during the next one or two years to levels that match power output at existing natural gas-fired power plants -- and building more natural gas plants in the long term. The introductory sections of the report are provided below. To access the full document click on the link at the bottom of this page.

Colorado's renewable energy standard: Its impact on the future electric capacity needs of the state

Cef_renewable_white_paper_thumb This paper investigates the impact of the passage of Colorado's expanded Renewable Energy Standard (RES) on the state's energy and generation capacity needs. In September 2006, the Colorado Energy Forum (CEF) issued a report which found that, in order to reliably meet Colorado's anticipated customer electricity needs, 4,900 MW of new electric capacity is required by 2025.

Grid Impacts of Wind Power Variability: Recent Assessments from a Variety of Utilities in the United States

Ewec06gridpaper_thumb In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. [4].
