Doug Barber

Xcel Energy was the first utility to commit to carbon-free operations by 2050, with an 80 percent reduction by 2030. To achieve this important goal, we recognized that we would have to think and act in innovative ways. This mindset is highlighted in our approach to plant maintenance. In 2019, Xcel created a unique unified learning organization. This approach has leveraged nuclear and nonnuclear expertise and training resources to improve craft skills, address long-term equipment reliability vulnerabilities, implement strategic initiatives, and improve sharing of resources—all of which has improved plant performance.

Xcel Energy’s unique approach has been proven successful in back-to-back Institute of Nuclear Power Operations Maintenance and Technical Training renewals at each of its plants with strengths directly attributed to our unified enterprise and nuclear learning approach, which ensures a focus on nuclear excellence, technician effectiveness, and business efficiency.

The Minnesota Public Utilities Commission (PUC) has approved Xcel Energy’s request for a certificate of need to expand spent fuel storage at the utility’s Monticello nuclear power plant.

The additional storage, according to the PUC, requires installation of a second concrete support pad and modular concrete storage system designed to hold 14 additional steel canisters.

Xcel had requested increased outdoor storage to accommodate its plan to extend Monticello’s operational life by 10 years, to 2040.

Monticello taken off line due to tritium leak

March 27, 2023, 12:01PMNuclear News

A recurring leak of water containing tritium has led to the temporary shutdown of Xcel Energy's Monticello nuclear power plant, in Minnesota.

“While the leak continues to pose no risk to the public or the environment, we determined the best course of action is to power down the plant and perform the permanent repairs immediately,” said Chris Clark, president of Xcel Energy–Minnesota, North Dakota, and South Dakota, in a March 23 news release. “We are continuing to work with and inform our state, federal, city, and county leaders in the process.”

Powering down the reactor to shutdown condition started last Friday.

An Xcel Energy news release issued last week regarding the leak of some 400,000 gallons of tritium-containing water at Minnesota’s Monticello nuclear power plant in 2022 has sparked a flood of news stories over the past few days—in large part because the general public had previously been unaware of the leak. (A low-level beta emitter, tritium is a common byproduct of nuclear reactor operation.)

Clean energy technology firm Bloom Energy has announced plans to install a 240-kW electrolyzer at Xcel Energy’s Prairie Island plant in Red Wing, Minn., to demonstrate the benefits of producing hydrogen with nuclear power. (One of Xcel’s two nuclear plants, Prairie Island houses twin 550-MWe pressurized water reactors.)

Clean hydrogen energy from nuclear power is having a good week

Using nuclear power technology to produce clean hydrogen is getting a visibility boost as the Department of Energy hosts a virtual three-day (June 6–8) Annual Merit Review and Peer Evaluation Meeting on the agency’s efforts to accelerate clean hydrogen production. On June 6, the DOE announced a notice of intent (NOI) to fund the Bipartisan Infrastructure Law’s $8 billion program to develop regional clean hydrogen hubs (H2Hubs) and the launch of a new Hydrogen Shot Incubator Prize that seeks “disruptive technologies” to reduce the cost of clean hydrogen production. That same day, Westinghouse Electric Company and Bloom Energy Corp. (a maker of solid oxide electrolyzer technology) announced a letter of intent to develop electrolyzers for use in the commercial nuclear power market and said they are “well positioned to support the U.S. Department of Energy’s developing hydrogen hubs.”

Hydrogen: The best shot for nuclear sustainability?

December 3, 2021, 3:00PMNuclear NewsSusan Gallier

Nuclear power plants are not quick to change. So when four utilities announce they will make room for shiny new electrolyzers and consider tweaking their business model, that’s news.

Nuclear power plants can leverage the energy stored in some of the world’s heaviest elements to generate the lightest: hydrogen. That is not news, but it casts an aura of alchemy over straightforward engineering. Amid the hype, and the hope of significant federal funding, it’s worth acknowledging that hydrogen has an industrial history over 100 years old. In the potential matchup of hydrogen and nuclear power, it’s nuclear that would be the newcomer.

Colorado county looking at SMRs to replace coal

October 21, 2021, 7:16AMNuclear News

The expected early retirement of a massive coal plant in Pueblo County, Colo., has the county commissioners mulling small modular reactors as a power source replacement.

The plant in question is Xcel Energy’s three-unit Comanche Generating Station, Colorado’s largest single source of greenhouse gas emissions. In 2018, Xcel received approval from the Colorado Public Utilities Commission (PUC) to retire Units 1 and 2 in 2023 and 2025, respectively. And earlier this year, the company filed a proposal to close the much newer Unit 3 in 2039—three decades earlier than expected. (Xcel also plans to run the unit at only 33 percent, beginning in 2030.) Meanwhile, environmental groups have been pushing for the closure of Unit 3 by the end of the decade.

Crapo

Intent on lowering that percentage, both the Senate and House earlier this week introduced bipartisan legislation to rapidly scale up and diversify emerging energy technologies. On July 27, Sens. Mike Crapo (R., Idaho), ranking member of the Senate Finance Committee, and committee member Sheldon Whitehouse (D., R.I.) introduced the Energy Sector Innovation Credit (ESIC) Act, or S. 2475. The credit, according to Crapo’s office, is a technology-inclusive, flexible investment tax credit (ITC) or production tax credit (PTC) designed to promote innovation across a range of clean energy technologies, including generation, energy storage, carbon capture, and hydrogen production.

Xcel Energy’s Prairie Island is the probable location for the nation’s first demonstration of high-temperature steam electrolysis at a nuclear power plant. Idaho National Laboratory, which plays a key role in a hydrogen demonstration project launched last year with Xcel Energy, Energy Harbor, and Arizona Public Service (APS), announced on November 9 that Prairie Island, which houses two 550-MWe pressurized water reactors, would likely be chosen over the one-unit boiling water reactor plant at Monticello.

Minneapolis-based Xcel Energy will work with INL to demonstrate a system that uses the plant’s steam and electricity to split water. The resulting hydrogen will be used at the power plant, but excess hydrogen could be sold to other industries. Hydrogen has applications in transportation and in industrial sectors, including steel and ammonia production.

More than $10 million in federal funding for the Xcel Energy demo was announced by the Department of Energy on October 8. It is just one phase of a project that showcases collaboration between the DOE’s Office of Nuclear Energy and Office of Energy Efficiency and Renewable Energy. Commercial hydrogen production via low-temperature electrolysis is being demonstrated at Energy Harbor’s Davis-Besse plant. APS, which operates the Palo Verde generating station, will build on the Xcel Energy demo to develop an initial design and feasibility assessment for plant modifications to integrate a reversible hydrogen electrolysis system with the plant’s secondary system and will include hydrogen storage infrastructure.
