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.
Fuel cell that carries energy generated from another source. It can be used in fuel cells to generate electricity with water as the only byproduct, or it can be burned for heat. Hydrogen can be produced from a variety of sources–renewable energy such as solar or wind, or gas plants, nuclear, and other energy sources–which dictate whether it can be considered “clean” or not.
Midcontinent Independent System Operator, serves northern Midwest, southeast, and parts of Canada
A non-profit organization that represents state public service commissions, which regulate essential utility services like energy, telecommunications, and water. Its stated aim is to improve the quality and effectiveness of public utility regulation. It has eight committees:
It also has a task force focused on Innovation.
Non-profit organization that operates to assure the effective and efficient reduction of risks to the reliability and security of the grid. It oversees six regional reliability entities and encompasses all of the interconnected power systems of Canada and the contiguous United States, as well as a portion of the Mexican state of Baja California. Its responsibilities include working with all stakeholders to develop standards for power system operation, monitoring and enforcing compliance with those standards, assessing resource adequacy, and providing educational and training resources as part of an accreditation program. NERC also investigates and analyzes the causes of significant power system disturbances in order to help prevent future events and produces reports about the near and long-term reliability forecast.
A document used by government agencies to announce a potential new rule or amendment to an existing one. This is an official part of the law-making process, allowing public comment before the rule is finalized. The acronym is frequently used by the Federal Energy Regulatory Commission (FERC).
A government-owned, contractor-operated facility, funded and overseen by the United States Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE). It specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation.
New York ISO
Wind turbines erected in bodies of water that harness the power of wind, converting it into electricity that is then transmitted to the mainland to power homes and businesses. Offshore wind farms are considered a renewable energy source.
