What is Demand Response? Owners Can defer construction of new power plants to meet peak demand. Customers Lower consumption when grid reliability is jeopardized, or energy prices spike.

Why Demand Response? Electricity providers can save money by reducing peak demand and deferring construction of new power plants. Electric system planners and operators can balance supply and demand. Customers can play an active role in the efficient utilization of the electric grid.

Types of Demand Response Incentive-based demand response Pay customers to reduce loads in response to grid reliability issues or high electricity prices. Price-based demand response Provides customers with rates that reflect the cost of electricity in different time periods. Real-time pricing (RTP) Critical-peak pricing (CPP) Time-of-use (TOU) tariffs Others
