Load flexibility, also known as demand flexibility, is defined as the ability of customers to optimize the timing and utilization of electricity to benefit both them and the electric grid. Customers use load flexibility to shift electricity usage (or load) from peak periods to off-peak periods, to reduce utility bills (demand charges, time-of-use, or real-time pricing), gain financial benefits from participating in load flexibility programs, or meet interconnection requirements (or other contractual agreements regarding available grid capacity). Load flexibility is a promising yet under-leveraged solution to maintain grid reliability, energy security, and affordability. It can be achieved through process equipment controls and changes or the installation of onsite energy generation and/or storage systems.
