Historically, the US power grid has primarily treated electricity demand as a (mostly) unalterable requirement that must be met by ramping dispatchable generation up or down to adjust the electricity supply. This system creates several drawbacks, including i) challenges associated with integrating intermittent renewable energy sources (such as solar and wind) that cannot be dispatched; and ii) inefficient use of resources, since the transmission, distribution, and generation systems must be built to meet the peak demand even though the peak occurs only a few hours during each year. Demand-side management (DSM) approaches can alter the net electricity required from the… [more]
