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.

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.
A measure of how efficiently electrical power is being used. It shows how much of the total power flowing in a circuit is actually doing useful work (active power) versus being ”wasted” as reactive power. A power factor closer to 1 means higher efficiency and fewer losses.
Sometimes also called a Public Service Commission (PSC), is a state-level governmental agency that regulates utilities like electricity, gas, and water. PUCs ensure that these essential services are provided fairly, reliably, and at reasonable prices, often by overseeing monopolies and protecting consumers.
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.

Generators with turbines rotating in sync with the grid frequency. They include large-scale thermal (coal and gas) and hydropower plants.
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:
