The Sioux Valley Energy Board of Directors approved an overall average rate adjustment of 9.1% as of January 1, 2026.

Members will see the rate change on February billing statements, which reflect January energy usage. Rate adjustment percentages will vary depending on members’ specific energy (kWh) usage.

Why is an increase needed? The primary reason why a rate increase is needed is to cover higher power supply costs. Power supply costs are a driving factor of SVE member electric rates because over 60% of Sioux Valley Energy’s costs go towards paying for power. Sioux Valley Energy’s power supply costs will increase by approximately 11% in 2026. On the local level, Sioux Valley Energy was able to get the rate increase down to an overall average of 9.1%.

Why are my rates going up?
Main rate classifications 2026

Sioux Valley Energy’s cost of power will increase by 11% in 2026. Any power supply increase is passed directly through to the member. The reason power supply rates are so impactful is because over 60% of SVE’s costs are attributable to power supply. SVE members will likely see increases in the future.

If a single-phase Farm & Rural Residential member or Urban Residential members uses 1,000 kWh a month, their monthly electric bill will increase $15.60 a month or $187.20 a year.

Basic Service Charge:

This fee helps pay for the electrical infrastructure (poles, wires, transformers, substations, etc.) that is required to get power to your home or business. It also helps pay for the maintenance of that equipment. There is a fixed cost for the infrastructure regardless of how much electricity you use (even if you use 0 kWh there is a fixed cost to have the service at your location). The average investment per account is approximately $12,500 plus ongoing maintenance costs.

Energy Charge:

This fee pays for the actual electricity (including power supply) that members use to power their homes and businesses. The energy charge is measured in kilo-watt hours (kWh). 

Demand Charge:

Currently only large power users have a demand charge on their power bill. This fee pays for the rate at which you are using electricity during a 15- or 30-minute period of highest power use throughout the month. Demand is measured in kilowatts (kW). In other words, it’s the amount of power required in an instant to satisfy the needs of all your connected equipment, lighting, etc. and anything else in your business requiring electricity at the exact same time. Residential and Rural Residential members have demand listed on their electric bills to help them monitor their individual demand impact on the electric system.

In other words, it’s the amount of power required in an instant to satisfy the needs of all your connected equipment, lighting, etc. and anything else in your business requiring electricity at the exact same time. Residential and Rural Residential members have demand listed on their electric bills to help them monitor their individual demand impact on the electric system. Demand may be charged in the future for Residential, Rural Residential, and General Service members to more accurately reflect power supply costs.

An easy way to think of energy and demand is through a water bucket analogy (see below). In this example, demand represents the speed of the water flow at any single moment in time and energy corresponds to the total amount of water that ends up in the bucket.

Understanding rates

Sioux Valley Energy studies and reviews its rates thoroughly each year through a multi-step process, based on revenue requirements. This work includes a cost-of-service study conducted by an outside engineering firm, a review/ analysis by an internal SVE rate committee, and review by the cooperative’s Strategic Leadership Team. The rate development process looks like this:

SVE Rate Design Process

 

No. The needed rate increase from our power suppliers does not factor in any generation or transmission for hyperscale data centers. Basin Electric Power Cooperative has a separate Large Load Program that is designed specifically to address the generation and transmission needs of data/AI centers ensuring they pay their own way without harming the cooperative’s “legacy” (Rural and Urban Residential, Commercial, etc.) members.

Each utility has its own method of recovering the cost of providing electricity to its customers. According to the US Energy Information Administration (EIA) the 2025 year to date average cost for electricity in the U.S. was 17.10 cents/kWh. With the increase, SVE’s average Residential rate (including Basic Service Charge) is 12.81 cents/kWh. Electric Power Monthly - U.S. Energy Information Administration (EIA). Many area utilities are increasing rates in 2026.

Sioux Valley Energy increased rates in 2024, 2025, 2026, and will likely increase rates in 2027.

The Cooperative is a not-for-profit electric utility. Our business model focuses on setting rates based on actual costs – profit is not the focus. In fact, any margin that is realized by the Cooperative is given back to the members in the form of capital credits. We are, however, required by lenders to maintain minimum financial benchmarks.

To minimize the need for a rate increase, we reviewed all expenses. The Cooperative decreased direct expenses in 2025 and are budgeting a decrease again in 2026. The result is a total reduction in direct expenses of approximately $300,000 since 2025.

However, because direct expenses only make up 6% of the budget, the impact of that is minimal. The driving force behind the rate adjustment is power supply costs (over 60% of the budget), which are not controllable expenses. Direct expenses include day-to-day activities such as cable locating, right-of-way clearing, pole testing, member billing and postage, member meetings, community development, software, director expenses, building expenses, dues, and outside services.

The answer to this question is “probably”. Our power wholesale power supplier, Basin Electric has indicated they will need to increase their rates in 2027 and likely future years as well.

ITG: Reasons for Basin Electric's Rate Increase

Utilities across the country (including electric cooperatives like Sioux Valley Energy) are working to build new electrical generation to keep up with increasing demand, which is putting pressure on your electric rates. On this Inside the Grid podcast, we visit with Sioux Valley Energy's General Manager and CEO, Tim McCarthy and Board President Dan Leuthold regarding the reasons for Basin Electric's upcoming rate increase.
