The scope of the project was to develop strategies to achieve the co-benefits of maintaining power systems reliability and protecting public health (from air pollution) during high electricity demand days (HEDDs). HEDDs are typically hot summer days when the demand for electricity is highest and the atmosphere is conductive to pollution formation such as ozone. Meeting high electricity demand during HEDDs requires dispatch of all generation resources, and demand response programs often lead to firing up of diesel backup generators.
