Vogtle nuclear reactor 3

For the first time in almost seven years, a new nuclear reactor has started up in the United States.

On Monday, Georgia Power announced that the Vogtle nuclear reactor unit 3 has started a nuclear reaction inside the reactor.

Technically, this is called “initial criticality.” It’s when the nuclear fission process starts splitting atoms and generating heat, Georgia Power said in a written announcement.

The heat generated in the nuclear reactor causes water to boil. The steam spins a turbine that’s connected to a generator that creates electricity.

Vogtle’s Unit 3 reactor will be fully in service in May or June, Georgia Power said.

The last time a nuclear reactor reached the same milestone was almost seven years ago in May 2016 when the Tennessee Valley Authority started splitting atoms at the Watts Bar Unit 2 reactor in Tennessee, Scott Burnell, a spokesperson for the Nuclear Regulatory Commission told CNBC.

“This is a truly exciting time as we prepare to bring online a new nuclear unit that will serve our state with clean and emission-free energy for the next 60 to 80 years,” Chris Womack, CEO of Georgia Power, said in a written statement. 

Including the newly turned-on Vogtle Unit 3 reactor, there are currently 93 nuclear reactors operating in the United States and collectively, they generate 20 percent of the electricity in the United States.

Nuclear reactors, which help combat global warming, generate about half of the clean, carbon-free electricity generated in the U.S.

Most of the nuclear power reactors in the United States were constructed between 1970 and 1990, but construction slowed significantly after the accident at Three Mile Island near Middletown, Pa. on March 28, 1979. From 1979 through 1988, 67 nuclear reactor construction projects were canceled, according to the U.S. Energy Information Administration.

However, because nuclear energy is generated without releasing carbon dioxide emissions, which cause global warming, the current increased sense of urgency in responding to climate change has given nuclear energy a chance at a renaissance.

The cost associated with building nuclear reactors is a major barrier to a potential resurgence in nuclear energy, however. And the new builds at Vogtle have become a bit of an epitome of that charge: The construction of the two Vogtle reactors has been plagued by cost overruns and delays.

Massachusetts launches a two-year V2X pilot program

Massachusetts launches a two-year V2X pilot program

Massachusetts is launching a first-of-its-kind statewide vehicle-to-everything (V2X) pilot program. This two-year initiative, backed by the Massachusetts Clean Energy Center (MassCEC), aims to deploy 100 bidirectional chargers to homes, school buses, municipal, and commercial fleet participants across the state.

These bidirectional chargers will enable EVs to serve as mobile energy storage units, collectively providing an estimated 1.5 MW of new storage capacity. That means EVs won’t just be getting power – they’ll be giving it back to the grid, helping to balance demand and support renewable energy use. The program is also focused on ensuring that low-income and disadvantaged communities have access to this cutting-edge tech.

The Massachusetts pilot is one of the largest state-led V2X initiatives in the US and is designed to tackle key challenges in deploying bidirectional charging technology. By strategically placing these chargers in a variety of settings, the program aims to identify and resolve barriers to wider adoption of V2X technology.

Massachusetts EV owners and fleet operators enrolled in the program will get bidirectional chargers capable of both vehicle-to-grid (V2G) and backup power operations at no cost. Here’s what they stand to gain:

  • No-cost charging infrastructure: Bidirectional charging stations and installation are fully covered for participants.
  • Grid resilience: With an estimated 1.5 MW of new flexible and distributed storage assets, the program strengthens Massachusetts’ energy infrastructure.
  • Clean energy integration: V2G technology allows EVs to charge when renewable energy is available and discharge stored energy when it’s not, supporting the state’s clean energy goals.
  • Backup power: EV batteries can be used as backup power sources during outages.
  • Revenue opportunities: Some participants can earn money by sending stored energy back to the grid.

Clean energy solutions firm Resource Innovations and vehicle-grid integration tech company The Mobility House are leading the program’s implementation. “With the charging infrastructure provided through this program, we’re eliminating financial barriers and enabling school districts, homeowners, and fleets to access reliable backup power,” said Kelly Helfrich of Resource Innovations. “We aim to create a scalable blueprint for V2X programs nationwide.”

“Bidirectional charging benefits vehicle owners by providing backup power and revenue opportunities while strengthening the grid for the entire community,” added Russell Vare of The Mobility House North America.

The program is open for enrollment now through June 2025. For more details, visit the MassCEC V2X Program webpage. A list of eligible bidirectional vehicles can be found on that page.

Compton, California, just got its first 25 electric school buses

Compton, California, has unveiled 25 new electric school buses – the school district’s first – and 25 Tellus 180 kW DC fast chargers.

Compton Unified School District (CUSD) in southern Los Angeles County is putting 17 Thomas Built Type A and eight Thomas Built Type C electric school buses on the road this spring. In addition to working with Thomas Built, CUSD also collaborated with electrification-as-a-service provider Highland Electric Fleet, utility Southern California Edison, and school transportation provider Durham School Services.

Environmental Protection Agency’s (EPA) Clean School Bus Program awarded funds for the vehicles in the program’s first round. EPA also awarded CUSD funds for the third round of the program and anticipates introducing an additional 25 EV school buses in the future.

“I can’t stress enough how vital grants like these are and the need for continued support from our partners in government at the state and federal level to fund additional grants for school districts and their transportation partners that are ready to deliver and operate zero-emission buses,” said Tim Wertner, CEO of Durham School Services.

CUSD, which serves Compton and parts of the cities of Carson and Los Angeles, currently serves more than 17,000 students at 36 sites. The district has a high school graduation rate of 93% and an 88% college acceptance rate. One in 11 children in Los Angeles County have asthma, which makes the need for emissions-free school transportation that much more pressing.
