Increased costs are blowin’ in the wind

10-03toddpdf_thumb Wind energy on the Pacific Northwest’s electricity grid has increased substantially. Often overlooked are the impacts of increasing wind generation on the reliability and affordability of electricity that very well might outweigh any of the promised environmental benefits. Todd Wynn and Eric Lowe explain how in Oregon wind power simply replaces a clean, reliable and affordable source of energy: hydroelectricity while inviting increased price volatility, increased rates, and the prospect of more greenhouse gas-emitting facilities.

Northwest Wind Integration Action Plan

Northwest_wind_integration_action_plan_thumb 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.
