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
The process of creating electricity.
Heat derived from the Earth’s interior, which can be harnessed for electricity generation. It’s a renewable resource, as the Earth’s internal heat is continuously replenished.
The electrical grid is a vast, interconnected network comprising power plants, transmission lines, substations, and distribution lines. Its purpose is to generate, transmit, and deliver electricity from producers to consumers across a wide geographic area.
A variety of technologies that improve the capacity, efficiency, and reliability of existing power grids. They are often lower cost and faster to deploy than major grid infrastructure upgrades like building new transmission lines. These technologies optimize the flow of electricity across existing infrastructure.
Refers to the ability of an inverter to synchronize with frequency and voltage on the grid. These are more common than grid forming and refer to how this technology takes its cues from the grid, not the other way around.
Refers to the ability of an inverter to actively control frequency and voltage on the grid, helping to ensure grid stability. They can provide ancillary services, such as inertia, voltage regulation, and frequency response, essential for maintaining grid stability.
Refers to the many solutions that help the grid withstand major events, such as extreme weather, natural disasters, or cyber attacks, without disruption.

For electricity infrastructure, like power lines and generating facilities, these requirements involve a range of considerations, including safety, environmental impact, and community engagement. Specific regulations vary by location and project type, but generally include distance requirements from existing infrastructure, environmental assessments, and engagement with landowners and stakeholders.
The conversion of sunlight into electricity using photovoltaics (PV) or solar thermal technologies. It’s a renewable energy source that is becoming increasingly important in the global energy landscape due to its sustainability and decreasing costs.
Refers to the real-time wholesale cost of electricity that fluctuates based on supply, demand, weather, and grid conditions.
Southwest Power Pool
Generators with turbines rotating in sync with the grid frequency. They include large-scale thermal (coal and gas) and hydropower plants.
A type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy.
