Three-phase service: Service where the facility has three energized wires coming into it. Requires more sophisticated equipment and tends to be more expensive to install and maintain.
Time-of-use rate: Prices for electricity that vary depending on what time of day the customer uses electricity. Designed to reflect the different cost the utility incurs to provide electricity during on-peak and off-peak periods.
