FAQs & Helpful Resources
What electric rate applies to large industrial customers?
Businesses with peak demand of 500 kW or greater typically qualify for Power & Light Large or specific Time-of-Use rates depending on load profile and eligibility.
What is the difference between Power & Light and Time-of-Use rates?
Power & Light Large is primarily demand-based with tiered energy pricing. Time-of-Use rates vary pricing by time of day and may reward businesses that can shift energy use outside peak summer hours.
How is billing demand calculated for large commercial customers?
Billing demand is based on the highest 30-minute kW measurement during the billing month, and may include seasonal ratchet provisions depending on the tariff.
What is a demand ratchet?
A demand ratchet uses your highest historical peak demand to establish a minimum billing demand for future months, particularly during seasonal periods.
What is load factor and why does it matter?
Load factor measures how consistently electricity is used compared to peak demand. A higher load factor indicates more efficient use of energy and may qualify customers for specific rate plans such as Time of Use - High Load Factor.
How long is the contract for large commercial or industrial business rates?
Contract terms vary by rate plan. Power & Light Large requires a five-year term, while Time of Use rates requires a one-year initial term.
