These incentivize customers to reduce, increase, or shift their electricity consumption in response to price spikes or grid reliability signals. Most programs encourage utility customers primarily through price incentives to shift electricity consumption from hours of high demand (relative to energy supply) to hours when energy supply is plentiful (relative to demand).
These encompass strategies and programs designed to influence electricity consumption patterns on the customer side of the meter. These initiatives aim to moderate electricity demand through methods such as financial incentives for energy conservation and energy efficiency measures, like improved insulation or the adoption of energy-efficient appliances.
Refers to electricity generation resources that power grid operators can control and adjust on demand to meet changing electricity needs. These include nuclear, hydropower, battery storage, and thermal power plants.
Small-scale energy generation and storage technologies located near the point where the energy is used, rather than at a centralized power plant. These resources–such as solar microgrids, rooftop solar, and battery storage–can be used to enhance or replace traditional energy sources and can operate independently or be connected to the main grid.
Refers to any unwanted or unplanned electrical event that interferes with the normal operation of the electrical grid. These can manifest in power outages, surges, and other events, and can originate from various sources within the electrical grid, such as loss of a large generating unit or another grid asset, such as a transmission line or transformer.
The ability of a piece of electrical equipment to stay connected to the grid through a short-term disturbance, thus helping keep the grid stable through the event. Inverter-based resources, such as photovoltaic solar arrays, wind turbines, and battery storage, can provide disturbance ride-through services, but require specific design of their control system to do so.
In energy regulation, it is a formal proceeding or official record initiated by a regulatory body (such as a Public Utilities Commission or the Federal Energy Regulatory Commission (FERC)) to address a specific issue or project. It serves as a repository for all submitted documents, evidence, and public comments.
A visual representation of how solar power generation impacts the daily electricity demand curve, particularly in regions with high solar adoption like California. It depicts a dip in net electricity demand during midday due to solar generation, followed by a steep increase in the evening as solar output decreases and demand peaks.
An independent agency that regulates the interstate transmission of natural gas, oil, and electricity. FERC also regulates natural gas and hydropower projects.
A United States law primarily regulating the interstate transmission and sale of electricity and the development of hydroelectric power. It was responsible for creating the body now known as FERC. It was created in 1920 and has been amended several times since.
Measures taken to ensure backup power, particularly of renewable energy, such as solar and wind generators. These requirements may require battery storage, ancillary services, or backup generation, such as an added gas plant to produce energy when a solar or wind plant does not.
Electricity is supplied to homes and businesses in the United States in the form of alternating current, and frequency is the rate at which an alternating current changes direction, as measured in hertz (Hz). Across the power grid there is a consistent frequency which in the United States is 60 Hz.
The ability of the grid to react to a change in
the frequency to bring it back to the normal operating frequency, which is 60 Hz in the United States
Midcontinent Independent System Operator, serves northern Midwest, southeast, and parts of Canada
The brief periods when electricity consumption is at its highest, often driven by factors like extreme weather or heat events. This is the highest amount of electricity demand for which a grid operator needs to plan.
A power plant that is designed to quickly ramp up and provide electricity during periods of high energy demand, such as during hot summer afternoons or cold winter evenings, to meet the increased needs of households and businesses. These plants generally only run during these peak events to supplement regular power generation.
A regulatory tool that ties a portion of utilities’ earnings to the utilities’ performance on desired regulatory outcomes, offering utilities opportunities to create the programs and services needed to advance emerging priorities.
The conversion of light into electricity at the junction of two substances exposed to light. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power.
Pennsylvania-New Jersey-Maryland Interconnection- services 13 states in Midatlantic and Midwest region
The rate of transfer of energy. It’s essentially how quickly energy is being used or converted from one form to another in an electrical circuit. Power is measured in watts (W), which represents one joule (J) of energy per second.
