Powering Your Future

Missouri River Energy Services (MRES) is committed to providing members and communities with efficient, cost-effective, reliable and ever-increasing clean energy. We’ve built a diverse portfolio of generation resources to reduce risk, increase reliability and focus on environmental stewardship. We work hard every day to find balanced solutions that will meet the electrical needs of our members and the thousands of customers they serve across our four-state service area.

Energy Sources

Fifty-nine of our 61 members receive an allocation of hydropower from the dams on the Missouri River, and they purchase, on average, about 40% of their energy needs from the federal government’s Western Area Power Administration (WAPA). MRES meets their remaining power supply needs with our diverse and reliable energy sources below.

Creating a Cleaner Energy Future

Creating a cleaner energy future is a top priority for MRES and our members, and we are delivering affordable, reliable, and ever-increasing clean energy to our members and their customers.

Over the past 15 years, MRES has added renewable and carbon-free resources to our power supply mix, including nuclear, wind and solar resources. As part of its commitment to a cleaner energy future, MRES launched the Bright Energy Choices program on Jan. 1, 2020, which allows members and their customers to choose 100% renewable or 100% carbon-free energy. In addition, MRES built a new hydroelectric power plant — the Red Rock Hydroelectric Project — near the member community of Pella, Iowa, that began commercial operation in Spring 2021. In our decisions, we’ve focused on environmental stewardship, along with reducing risk and increasing reliability.

2020 — 84% Carbon Free

Greenhouse gasses, and specifically carbon dioxide (CO2), are a source of concern due to their association with global warming. That’s why MRES has been tracking our CO2 emissions and working to reduce our carbon footprint for the past 15 years.

In 2005, our baseline year for tracking CO2 emissions, the MRES member power supply resource mix was 50% carbon-free, largely due to members’ allocations of hydropower. In 2020, MRES members achieved an 84% carbon-free energy mix through the addition of renewable and carbon-free resources, along with the reduced operation of our coal-fired power plant.

Carbon Intensity Reduction

Since 2005, MRES reduced its carbon intensity — the amount of CO2 emissions per kWh — by 72% as the result of increased energy sales, increased use of clean energy resources, and decreased use of carbon-emitting resources.

Counting Environmental Attributes

MRES takes responsibility for all emissions produced on its behalf from fossil fuel resources, whether used for member load or sold as surplus into an energy market. MRES is also entitled to the Renewable Energy Certificates (RECs) for energy generated at the wind and solar farms that are under contract to MRES. This methodology is consistent with the way nitrogen oxides and sulfur dioxide emissions are currently treated under the Clean Air Act.

For this reason, market purchases are considered free from any environmental attributes (renewable or otherwise) because the resource owner is responsible for the emissions, or has taken credit for the renewable attributes, of energy sold into the market. Similarly, the purchasers of energy from the market have no way to mitigate emissions produced, nor do they have any right to the renewable attributes, for energy purchased from the market.
