Major step on wind energy

Xcel says wind power will mostly supply intermittent and peak power - energy demands that fluctuate day to day or even hour to hour. Unfortunately, that means it still must rely on coal, the most polluting fossil fuel, supplemented by natural gas, the most expensive fossil fuel, for its base load (the kind of electricity that's always on).

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].
