Bill questions

Frequently asked by customers

Why is my electric bill higher than usual?
When trying to determine why your bill is high, first compare the energy usage charts on this year's electric service statements with those on last year's statements. Are you using more electricity?

Check the section of your bill that explains the relative impact of outside temperatures. If temperatures were colder than last year your electric bill will be higher as well. To make a more thorough analysis, you may want to consider conducting an online energy audit of your home using Bill Analyzer and read this overview of some factors that contribute to high bills. If you still have questions contact us.

What should I do if I don't have enough money to pay my bill?
If you're unable to pay your electric bill, contact us as soon as you can. If the problem is temporary, the more quickly you contact us, the more likely we can reach a suitable agreement. You may want to consider using our Even Monthly Payment plan, which makes budgeting easier. If the problem is likely to last for some time, you may want to contact your local energy assistance agency or Community Action Council for help.

Do I have to pay a security deposit when I order new electric service?
New Otter Tail Power Company customers or previous customers who have a good credit history with us do not have to pay a security deposit. Previous customers have a good credit history if they've had fewer than three disconnect notices and haven't had service disconnected for not paying an electric bill within the last 12 months. If we collect a deposit, it will be based on two months' average bill.

If I have to pay a deposit, will I receive interest on it?
Yes, your deposit draws interest. The interest rate is 0.3 percent in Minnesota, which is based on the average yield of one-year United States Treasury securities adjusted for constant maturity for the last full week in November. The interest rate is 7.0 percent in South Dakota. The interest rate is 0.85 percent in North Dakota, which is determined by the rate paid by the Bank of North Dakota on a six-month certificate of deposit as of the first business day of each year.

Why do you estimate some electric bills? How do you determine the amount of an estimated bill?
We estimate bills when we are unable to read the meter. This may happen for a variety of reasons, including inclement weather or inaccessible meters. Estimating bills helps keep our costs down and our rates affordable.

To estimate a bill, we evaluate a customer's prior energy use patterns and adjust for the effect of temperatures during the billing period.

What is the Resource Adjustment/Energy Adjustment cost on my bill?

In Minnesota the Resource Adjustment reflects four costs:

  • The cost of fuel we use to generate electricity to serve our retail customers, transportation costs for that fuel, and costs we incur to buy energy to supplement our own power plants, minus a base cost for energy that already is part of the per-kilowatt-hour rate you pay.

  • The Conservation Improvement Program surcharge. The CIP surcharge represents our investment in energy-efficiency programs that help our customers save energy.

  • The Renewable Resource Adjustment. The Renewable Resource Adjustment allows our company to recover costs associated with renewable energy facilities that we own. Those costs include operating and maintenance expenses, depreciation, income and property taxes, and a return on our investment.

  • The Transmission Cost Recovery Rider. The Transmission Cost Recovery Rider allows our company to recover costs associated with transmission additions designed to meet our customers' growing energy needs, accommodate the delivery of additional renewable energy, and enhance transmission system reliability. At this time, we do not have a Transmission Rider in North Dakota or South Dakota. If we have not implemented a Transmission Rider prior to filing our next rate cases in those states, we will propose cost recovery in our rate cases.

In North Dakota the Energy and Renewable Adjustment reflects:

  • The Energy Adjustment, which includes the cost of fuel we use to generate electricity to serve our retail customers, transportation costs for that fuel, and costs we incur to buy energy to supplement our own power plants, minus a base cost for energy that already is part of the per-kilowatt-hour rate you pay. Asset-based sales margins also are included as a credit to the energy adjustment calculation.
  • The Renewable Resource Adjustment, which allows our company to recover costs associated with renewable energy facilities that we own. Those costs include operating and maintenance expenses, depreciation, income and property taxes, and the cost of capital invested. The energy generated by these facilities reduces the amount of fossil fuel and purchased energy necessary to meet our customers' needs. That reduces the amount of purchased-energy and/or fuel costs in the Energy Adjustment.

In South Dakota the Energy Adjustment reflects the cost of fuel we use to generate e lectricity to serve our retail customers, transportation costs for that fuel, and costs we incur to buy energy to supplement our own power plants, minus a base cost for energy that is already part of the per-kilowatt-hour rate you pay.

How is the cost-of-energy adjustment applied to my bill?
 The cost-of-energy component of the Resource Adjustment in Minnesota, or Energy Adjustment in North Dakota and South Dakota, reflects changes in the cost for fuel we use to generate electricity, transportation costs for that fuel, and the costs we incur to buy energy to supplement our own power plants minus the base amount included in the per-kilowatt-hour rate you pay.

If Otter Tail Power Company purchases fuel and energy at less than the amount included in our base rate we pass the savings on to our customers in the form of a credit on their bills. If the cost is more than our base rate, the incremental difference is passed on to customers through the Resource (Energy) Adjustment.

Why has the cost-of-energy adjustment been increasing? 
Several things contribute to the increase:

  • Higher fuel and transportation costs.
  • Higher natural gas and other fossil fuel prices impacting the cost of power purchased on the wholesale market and the cost of running peaking units that use natural gas and fossil fuel.
  • Increased demand for energy on the wholesale market.
  • Prolonged periods of extreme weather conditions.

Where do you see cost-of-energy adjustments going in the future?
We expect to see a continued upward trend in the cost-of-energy adjustment charges.

If I switch to natural gas, will I avoid this cost-of-energy adjustment?
 No, natural gas prices include a purchased gas adjustment, much like the cost-of-energy adjustment, that is passed directly to customers. Usually these fluctuations are greater than with electricity. Because the natural gas industry in the United States is largely deregulated, the wholesale price of gas fluctuates with supply and demand. At this time supply sources are tight and demand is high, resulting in higher prices for natural gas. Natural gas utilities, which transmit and distribute gas to consumers, pass price changes directly to consumers. In average years, the cost of gas accounts for about one-third of consumers' bills, with distribution costs and transmission costs accounting for the remaining portion. Holding consumption constant, a 10 percent change in the wholesale price of natural gas results in a 3.3 percent change in charges on consumers' bills.

Why do controlled-service customers have a cost-of-energy adjustment?
 The cost-of-energy adjustment covers normal month-to-month variations in our own fuel costs for producing or purchasing energy to serve retail load. Because the actual control period for controlled-service customers is typically less than 10 percent of the time, controlled-service customers must help pay for the variations in fuel costs for the remainder of that time.

The costs to serve retail load, whether purchased energy or otherwise, is part of all rates. The change in the cost of fuel and purchased energy is passed on to customers on all rates.
