Are Demand Charges The Next Big Thing In Residential Electricity Rates? - CleanTechnica
Consumer technology is going to exist indefinitely, perhaps for as long as the human species exists. At CleanTechnica, we try to feature consumer technologies that help to reduce global warming pollution and other types of pollution. For example: electric cars, solar panels, bikes, energy efficient appliances and electronics, and green smartphone apps. Keep an eye on this category for all sorts of fun and cool, helpful consumer technology. Demand charges for commercial and industrial customers have long been a part of the electric industry. Since utilities need to build infrastructure to meet both instantaneous and long-term requirements, the utility bill contains both an energy charge, which measures the amount of electricity a customer uses over time, and a demand charge, which... However, residential customers are rarely subject to a bill with a demand charge. This is because, until recently, residential electricity loads were pretty much the same from one customer to the next. We all (more or less) woke up, took a shower, went to work, came home, turned on the lights, cooked dinner, watched TV, did a load of laundry, went to bed. With each customer in the residential class looking an awful lot like the next, utilities and regulators could lump energy and demand elements together into one $/kWh price. All residential customers are not the same. We now have access to LED lights, smart thermostats, plug-in electric vehicles, rooftop solar, demand-flexible water heaters, battery energy storage, and myriad other technologies that make our respective loads and our consumption patterns... Critically, it is now inexpensive to meter these differences, including time of use and the magnitude of the demand. Separating out demand charges may be a good way to promote more fairer cost allocation among ratepayers, while also motivating customers to reduce strain on the system. More than a dozen utility companies across the country have implemented or are currently considering residential demand charges. WHAT IS A DEMAND CHARGE. A demand charge is based on the maximum amount of energy a customer uses at any one instance over the course of a billing cycle.
