An emergency order issued by the United States Department of Energy (DOE) under Section 202(c) of the Federal Power Act. It allows the Secretary of Energy to temporarily order connections of facilities and the generation, delivery, or transmission of electricity to best meet an emergency caused by war, a sudden increase in demand, or a shortage of energy or facilities. These temporary orders can also exempt power plants from federal, state, or local environmental rules and have historically been used to prevent outages during severe weather events or supply shortfalls.
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.
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.
The maximum amount of electrical power that can be reliably moved from one geographic region of the power grid to another, essentially indicating the ability of the transmission lines connecting those regions to transport electricity between them without causing instability or exceeding safety limits. It’s a crucial concept for ensuring the safe and efficient operation of the power system, particularly in the context of electricity markets and grid planning.
Equipment used to increase and decrease voltages at grid interfaces.
The process (and infrastructure) of moving large amounts of electrical power over long distances from where it is generated, like a power plant, to substations closer to consumers.
Measure of the rate of energy transfer over a unit of time, with one watt equal to one joule (J) per second.
A form of renewable energy that uses the kinetic energy of wind to generate electricity. It involves capturing the wind’s energy through turbines, which then convert this mechanical energy into electricity. Modern wind power generation primarily relies on wind turbines, often grouped into wind farms, connected to the electrical grid.
The increase in energy demand during the winter months, usually due to heating needs. This can lead to higher energy prices and bills for a number of reasons, including:
