plans, these changes can be either more or less accommodating to the natural characteristics of wind power plants.
•Wind forecasting tools and other technologies that are commercially available can be employed to reduce system operating costs associated with wind variability.
• Since wind is primarily an energy, not a capacity, source, no additional generation needs to be added to provide back-up capability provided that wind capacity is properly discounted when determining generation capacity adequacy. However, wind generation penetration may affect the mix and dispatch of other generation on the system over time, since non-wind generation is needed to maintain system reliability when winds are low.
• Wind generation will also provide some additional load carrying capability to meet forecasted increases in system demand. This contribution is likely to be up to 40 percent of a typical project’s nameplate rating, depending on local wind characteristics and coincidence with the system load profile. Wind generation may require system operators to carry additional operating reserves. Given the existing uncertainties in load forecasts, studies indicate that the requirement for additional reserves will likely be modest for broadly distributed wind plants. The actual impact of adding wind generation in different balancing areas can vary depending on local factors. For instance, dealing with large wind output variations and steep ramps over a short period of time could be challenging for smaller balancing areas, depending on the specific situation.
Wind energy use has grown significantly across the United States and globally in recent years in response to increasing recognition of its environmental, economic and energy security benefits. Although many regions have already successfully integrated large amounts of wind energy with their electric grids, there is still a great deal of misunderstanding about wind and grid integration. Variability, similar to that introduced by wind energy, is nothing new for system operators, who have always accommodated random variations in load and the sudden loss of conventional generating units while maintaining reliability. Moreover, greater use of wind forecasting tools and the increasing geographic diversity of wind energy facilities continue to reduce the impact of wind’s variability on the grid. With reasonable changes, grid operators can tap the flexibility of different components of the electric grid to reliably integrate large amounts of wind energy at low cost.
