Google to bring shuttered nuclear power plant back from the dead

In a significant move towards sustainable energy, Google has announced its collaboration with NextEra Energy to reinstate the Duane Arnold Energy Center in Iowa, which ceased operations in 2020. This partnership comes after NextEra spent a year seeking a suitable ally to revive the reactor, aligning perfectly with Google's commitment to enhancing its zero-carbon energy portfolio for its expanding data center operations. The Duane Arnold plant was shut down following a severe derecho that compromised part of its secondary containment system, essential for preventing the release of radioactive materials. Originally, this facility had the capacity to produce 601 megawatts of electricity, and with the planned renovations, it aims to boost output by an additional 14 megawatts. NextEra has set a target to restart the facility by 2029, entering into a 25-year agreement with Google to purchase a majority of the generated power. The remaining electricity will be sold to the Central Iowa Power Cooperative, which currently owns a 20% stake in the plant. NextEra has indicated intentions to acquire the co-op's stake along with that of another minority owner. The revival of nuclear power is gaining traction as companies search for reliable energy sources to meet increasing electricity demands. This isn’t the first time a closed reactor has been brought back to life; Microsoft previously announced plans to collaborate with Constellation Energy to restart a reactor at Three Mile Island, which was shut down in 2019. This reactor is expected to become operational by 2028, with an estimated cost of $1.6 billion. Restarting existing reactors is seen as an efficient way to add nuclear capacity to the energy grid, potentially reducing the timeline significantly compared to constructing new plants. However, these projects still require several years to complete, positioning them against the backdrop of natural gas projects, which also have lengthy development periods. In the interim, companies like Google are exploring solar and battery solutions, which can be deployed much faster, thus significantly shortening the time required to power new data centers.
