Small General Service (SGS)

Peak Demand

If your small business can avoid using a lot of energy at any one time during on-peak hours, our Small General Service Peak Demand pricing plan might be right for you.

How does SGS Peak Demand work?

This plan combines a lower usage-based rate with a "demand" charge based on your business' highest hourly usage during on-peak time-of-use hours. If that hourly peak greatly exceeds your average use, this plan could increase your costs. But if your business' usage is relatively steady and you can space out energy-intensive tasks, you may enjoy lower energy costs on this plan.

For example, avoiding the simultaneous use of large appliances and equipment such as air conditioning, lighting, computers, copiers and printers during on-peak hours will reduce your demand and increase your savings. Combine this with a lower usage-based rate, and you have the power to reduce your monthly bill.

What are the potential advantages of this plan?

Demand rates empower customers to lower their energy costs by making smart choices about how they use energy. TEP's service costs are driven by the need to satisfy customers’ highest demand, even if it only occurs once each month. When that maximum usage level goes down, so does the cost of providing all of our customers with safe, reliable service.

Our SGS Peak Demand plan is designed to reward customers who do their part to reduce demand on the electric grid during peak usage periods. Reducing the peak energy demand promotes more efficient use of our energy resources and can help limit future rate increases.

What are the potential disadvantages of this plan?

If your business uses a lot of power during on-peak hours, your energy costs could increase under our SGS Peak Demand plan. That’s true even if your hourly usage reaches a high level only once during a billing cycle. The Demand Charge reflects the cost of resources and facilities TEP must build and maintain to satisfy even occasional needs.

Also, please be aware that customers who leave this plan cannot return to SGS Peak Demand for at least 12 months.
