How does wind, as a generation source, integrate into our electric grid?
Vermont is part of the New England electric power grid known as ISO New England (ISO-NE, more information at www.iso-ne.com), which is comprised of many types of generators: nuclear, coal, hydro, wind, biomass – and especially natural gas (+/- 40%). The grid is designed to handle varying electric loads and various types of generation facilities supplying the electricity. Operation forecasting monitors weather conditions, total expected generation, and projected actions required to maintain system reliability. Grid operators are aware of the changing generating sources whether it be a large nuclear plant, or a smaller wind facility and are prepared to interchange various “quick-start” generation sources, such as natural gas and hydro plants when needed. Wind is grouped with other on-demand sources of electricity, meaning when available it will be utilized.
