Power

The U.S. intends to triple its nuclear generating capacity by 2050 to meet the expected growth in electricity demand and expand carbon-free power production. In a recently related roadmap to achieving that goal, the outgoing Biden administration said the U.S. aimed to have 35 gigawatts (GW) of new nuclear capacity either in operation or under construction by 2035. It also outlined the key roles that restarting previously shut reactors, uprating some facilities to produce more power and the development of microreactors could play in the years ahead. In today’s RBN blog, we’ll discuss the report’s key findings and recommendations and what they tell us about the future of U.S. nuclear power. 

Texas is the fastest-growing state for electricity consumption in the nation and the Electric Reliability Council of Texas (ERCOT), which is responsible for about 90% of the state’s electricity service, said earlier this year that peak power demand could nearly double in just six years — from about 85 gigawatts (GW) currently to as much as 150 GW by 2030. The sudden increase is driven primarily by data centers and artificial intelligence (AI), cryptocurrency mining, the state's growing population and increasing temperatures. In today’s RBN blog, we’ll discuss how Texas intends to address its growing appetite for power. 

Soaring demand for around-the-clock electricity, tied to the development of large-scale data centers, has sparked a renewed interest in carbon-free nuclear power. Given that conventional nuclear plants can be very challenging to site and permit, there’s been a lot of talk about installing small modular reactors (SMRs) at the sites of coal-fired power plants that have been taken offline for environmental and economic reasons but still have critical connections to the power grid and other infrastructure. In today’s RBN blog, we examine the potential to replace coal with nuclear and preview our latest Drill Down Report on the growing enthusiasm for nuclear power in the U.S. 

If all goes to plan, Texas’s isolated power grid will one day be connected to a pair of neighboring states via a massive transmission line called Southern Spirit. The project is designed to increase grid reliability, reduce blackouts and drive down energy bills, but it could be years before it becomes a reality. And while the transmission line will connect Texas with Louisiana and Mississippi, it is more akin to a drawbridge that can be raised or lowered as needed without subjecting the Electric Reliability Council of Texas (ERCOT) grid to federal oversight. In today’s RBN blog, we’ll discuss what the Southern Spirit transmission line would mean for Texas. 

The prospect of a massive buildout of data centers across the U.S. has utilities preparing for a surge in power demand. And while access to an uninterrupted power supply is a critical factor for companies deciding where to build a data center, it’s not the only variable — power prices and proximity to customers also play a major role. In today’s RBN blog, we’ll look at where data centers are deployed across the U.S., the major factors that determine where a facility gets built, and how the sudden expansion is playing out in the major U.S. technology hubs. 

The growing number of energy-intensive data centers coming online across the U.S. is spurring utilities to ramp up plans to add new sources of power generation but also complicating efforts to decarbonize. One of the hottest topics in energy today is how plans to restart shuttered nuclear plants and build new small modular reactors (SMRs) could help accomplish both goals. In today’s RBN blog, we’ll look at why data centers and nuclear power seem like a natural fit, examine which shuttered plants might be brought back to life, and outline plans by a pair of U.S. economic titans to bring new advanced reactors online. 

There is a lot of talk about the best way to meet the expected increases in U.S. power demand, driven by manufacturing growth and the rapid development of large-scale data centers, which has sparked renewed interest in nuclear power. The most recent reactors to come online were Units 3 and 4 at Georgia’s Vogtle nuclear power station, but they came in well over budget and far behind schedule. Still, the startup of those units is a significant milestone as they are the first new reactors to come online in the U.S. since 2016. In today’s RBN blog, we’ll discuss the lessons learned from the Vogtle project and what they might mean for future nuclear development. 

Storms that form in the Gulf of Mexico (GOM) during hurricane season don’t just dissipate once they make landfall and can inflict havoc on onshore assets. Storm damage and flooding can delay plant restarts, but so can power outages, as we saw when Hurricane Beryl hit the Texas/Louisiana region in July. And while there were no major refining or production assets in the path of Hurricane Helene, which slammed into the Florida Panhandle on September 26, widespread damage illustrated the potential risk to onshore infrastructure. In today’s RBN blog, we will examine how hurricanes have disrupted onshore assets and explain why power restoration is often the Achilles’ heel in plans to resume normal operations.

The Nuclear Regulatory Commission (NRC) is preparing to oversee a restart of a shuttered nuclear power plant for the first time — the Palisades Nuclear Plant in Michigan. Other reactors have successfully restarted after stretches of inactivity but Palisades was in the process of being decommissioned and no longer has its operating license, so it faces a complicated — and unprecedented — path forward, helped in large part by a $1.52 billion conditional loan guarantee from the U.S. Department of Energy (DOE). In today’s RBN blog, we’ll discuss what it will take to restart the Palisades plant, which could provide carbon-free electricity for 800,000 homes. 

In Texas, rising power demand, increasing dependence on variable-output renewables, and declining availability of dispatchable fossil-fired plants to back up wind and solar have left the Electric Reliability Council of Texas (ERCOT) power grid in a pickle. As part of its response, the Public Utility Commission of Texas (PUCT) adopted a tool called the Performance Credit Mechanism (PCM) to help ensure the grid will be able to meet a yet-to-be-defined reliability standard. But while key metrics for the PCM have been identified, the details will determine which dispatchable resources will be supported with additional revenue, how much the whole approach will cost, and how effective it might be. In today’s RBN blog, we explore the debate ahead of the PUCT’s August 29 meeting — where it is expected to finalize rules around the PCM — and explore the difficulty of compensating generators annually so that they are also there for those once-in-10-year events. 

There’s been a lot of discussion lately about the best way to meet the expected increases in U.S. power demand, driven in part by manufacturing growth and the rapid development of large-scale data centers. That has spurred a renewed interest among regulators, industry leaders and the general public in nuclear power. But while traditional reactors are known for their cost overruns and construction delays as much as the massive amounts of carbon-free power they produce, some see a better way forward in the form of small modular reactors (SMRs). Advocates with “uranium fever” say they can be built without many of the problems that accompany their larger cousins and offer a number of potential advantages, including siting flexibility, price and efficiency. In today’s RBN blog, we’ll look at the state of nuclear power in the U.S., examine the potential for SMRs, and discuss the hurdles they face to obtaining the necessary permits and ultimately beginning operation. 

Texas and California are opposites in many ways, including their expectations for power prices in the summer ahead. Texas set single-day demand records several times last year and is anticipating more sizzling temperatures — and higher power prices — this year with demand expected to be near available supply. It’s the opposite for California, where the state’s extensive renewable buildout and higher-than-normal hydropower resources are helping keep a lid on power costs. In today’s RBN blog, we’ll examine the factors impacting Texas and California that are causing these polarizing power conditions.
