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.
