Power Factor

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.

PUC

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.

Watts

Measure of the rate of energy transfer over a unit of time, with one watt equal to one joule (J) per second.

Wind power

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.

Winter peaking

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: 

  • Strained energy grid: The high demand can strain the energy grid, which can cause utilities to work harder to meet the need.
  • Seasonal rate adjustments: Many energy providers adjust rates based on seasonal demand.
  • Increased use of lighting: Shorter and darker winter days can lead to greater use of in-home lighting.
