  Flexibility is a key enabler for the smart grid, required to facilitate
Demand Side Management (DSM) programs, managing electrical consumption to
reduce peaks, balance renewable generation and provide ancillary services to
the grid. Flexibility analysis is required to identify and quantify the
available electrical load of a site or building which can be shed or increased
in response to a DSM signal. A methodology for assessing flexibility is
developed, based on flexibility formulations and optimization requirements. The
methodology characterizes the loads, storage and on-site generation,
incorporates site assessment using the ISO 50002:2014 energy audit standard and
benchmarks performance against documented studies. An example application of
the methodology is detailed using a pilot site demonstrator.
