What is the process by which utilities rates are set in the US
The price of a utility's products and services will affect its consumption. As with most demand curves, a price increase decreases demand. Through a concept known as rate design or rate structure, regulators set the prices (known as "rates" in the case of utilities) and thereby affect the consumption. With declining block rates, the per-unit price of utility consumption decreases as the energy consumption increases. Typically a declining block rate is offered only to very large consumers. If conservation is the goal, regulators can promote conservation by letting prices rise. A third possible rate design is a flat rate which charges the same price for all consumption.
