2025 Rate Change

Due to higher power supply costs, the Sioux Valley Energy Board approved an overall average increase of 4.9% as of January 1, 2025. Members will see the rate change on their February billing, which reflects January energy usage. Rate adjustment percentages will vary depending on members' specific energy (kWh) usage. Click HERE to see the 2025 Rates.

Power supply costs account for more than 60% of Sioux Valley Energy’s expenses. Sioux Valley Energy’s wholesale power supplier, Basin Electric Power Cooperative, has announced an approximate 7% increase for the coming year. Additionally, the Western Area Power Administration (WAPA) has announced a nearly 14% rate increase over two years.

Sioux Valley Energy’s power supply costs will increase by 7.6% in 2025. Any power supply increase is passed directly through to the member. The reason power supply rates are so impactful is because approximately 60% of SVE’s costs come from power supply. Last year most of the rate increase stemmed from higher distribution costs – things like costs of materials, equipment, services, billing, labor, financing, etc.

Reasons driving rate increase

 

Basin Electric Power Cooperative's increase is driven by the following factors:

1. Load Growth and Investments in Reliability: Basin Electric is making significant investments in new generation and transmission facilities to support member load growth across its entire system, and it’s critical to invest in existing facilities to maintain reliability. To accommodate this growth, Basin Electric is investing approximately $8 billion over the next 10 years in transmission and generation assets to ensure reliable electricity for our members.

2. Decreased Surplus Sales in Western Markets: Market dynamics have been impacted by changes in the generating fleet in the western part of the United States. Increasing amounts of hydro and renewable energy generated in the western market are often lower priced than what our wholesale power supplier (Basin Electric) can produce it for. This limits Basin Electric’s ability to sell excess generation to the western markets.

3. Impacts of Inflation: There have been cost increases for internal labor, contracted labor, materials, and maintenance, in addition to higher costs of borrowing money (higher interest rates) and increased insurance premiums.

4. Volatility of Power Markets: Power markets have become more volatile, resulting in dramatic price movements. Increasing intermittent generation such as wind and solar, swings in natural gas prices, and increasing electricity demand are primary contributors to volatility. While this is managed through generation and hedging, the cost of this is increasing.

Here at home, Sioux Valley Energy has also been facing upward pressure on the cost of materials, equipment, labor, and financing.

The Western Area Power Administration (WAPA) increase is driven by the following factors:

5. Increasing Hydropower Costs: As for the Western Area Power Administration (WAPA), the top reason for the rate increase is drought. Dams and hydropower facilities did not generate enough power due to drought, which forced WAPA to purchase power to meet its obligations. It is also dealing with increased operation and maintenance costs for things like material and labor.

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. 

If a single-phase farm and rural residential member uses 1,500 kWh a month, their monthly electric bill will increase $10.50 a month or $126 a year.

If a residential member uses 1,200 kWh a month, their monthly electric bill will increase $8.40 a month or $100.80 a year.

Sioux Valley Energy raised its rates in 2024, prior to that the last increase occurred in 2020. Sioux Valley Energy is having to increase rates in 2025 due to higher power supply costs which are passed directly back to the member. The Cooperative was able to reduce its direct expenses. These costs 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.

Each utility has its own method of recovering the cost of providing electricity to its customers. According to the US Energy Information Administration (EIA) as of July 2024 the average cost for electricity in the U.S. was 16.63 cents/kWh. The average cost for Minnesota residents was 16.33 cents/kWh and the average for South Dakota residents was 13.85 cents/kWh. With the increase, SVE’s average residential rate (including basic service charge) is 13.59 cents/kWh. This analysis shows that Sioux Valley Energy is less than the average rate in South Dakota and significantly lower than the average rate in Minnesota. https://www.eia.gov/state/data.php?sid=SD

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 and were able to decrease direct expenses in 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 (61% 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.

There is a cost to the Brandon building. However, the rate impact is minimal because this is a capitalized expense and is spread out over a time period of 50 years, so both existing and future members pay for it. This expansion is necessary to prepare the Cooperative to serve its members well into the future. The capitalized expense of the Brandon building expansion did not impact the decision to increase rates in 2025 because that increase is attributable to power supply costs.

On an average $120 electric bill, approximately 91 cents will go towards the Brandon building expansion. That is three-quarters of one percent (0.76%) of your electric bill.

The answer to this question is “probably”. Our power wholesale power supplier, Basin Electric has indicated they will need to increase their rates in 2026 as well. In addition, the Western Area Power Administration (WAPA) will have at least one more year of rate increases in 2026.
