Georgia Power recently announced the successful placement of the basemat structural concrete for the nuclear island at the Vogtle Unit 4 nuclear expansion site near Waynesboro, Ga. Unit 4 is the second of two units currently under construction at Plant Vogtle.

This latest milestone marks a significant accomplishment in the construction of the project, among the first new nuclear units to be built in the United States in three decades. When complete, Plant Vogtle will be the only four unit nuclear facility in the country. 

The basemat concrete placement was completed in just under 41 hours. The efficiency of this placement matches the best time achieved worldwide. The Unit 4 placement encompassed approximately 7,000 cubic yards of concrete, which will serve as the foundation for all of the nuclear island structures, including the containment vessel and the shield building. It covered an area approximately 250 feet long and 160 feet wide at its widest point, and the concrete measured six feet in thickness.

Approximately 600 workers, including 500 craft workers representing the building and construction trades, participated in this milestone as part of a coordinated effort between Georgia Power, Southern Nuclear, Westinghouse and CB&I. 

The Unit 4 nuclear island has been fully formed and backfilled to grade elevation. The containment vessel bottom head and supporting CR10 cradle are completed and will be placed on the Unit 4 nuclear island following concrete curing. In parallel, the Unit 4 turbine building foundation has been completed and wall sections are currently being placed that also will take the turbine building to grade elevation.

“As we reach the midpoint in the historic construction of units 3 and 4, the visible progress at the site is setting the stage for a secure energy future for Georgia and the rest of the country,” said Buzz Miller, Georgia Power Nuclear Development executive vice president and president of Southern Nuclear Development.

The Vogtle 3 and 4 project is part of Georgia Power's long-term, strategic vision for providing energy for Georgians for decades to come.  It is the largest job-producing project in the state, employing approximately 5,000 people during peak construction and creating 800 permanent jobs when the plant begins operating.

Southern Nuclear, a subsidiary of Southern Company, is overseeing construction and will operate the two new 1,100-megawatt AP1000 units for Georgia Power and co-owners Oglethorpe Power Corp, the Municipal Electric Authority of Georgia and Dalton Utilities. Georgia Power owns 45.7 percent of the new units.

UK Nissan fleet owners receive commercial charging service

V2G technology developed by DREEV can recharge an EV battery when electricity is at its cheapest, and discharge excess energy to sell back into the grid

UK fleet owners of Nissan Leaf and e-NV200 models can avail of a new commercial charging service using vehicle-to-grid (V2G) technology.

The service, designed to support the grid through low carbon energy consumption, is being provided by EDF, through Group subsidiary DREEV, in partnership with Nissan.

The V2G technology developed by DREEV, which is a joint venture between EDF and Nuvve, which specialises in V2G technology, allows for two-way energy flow; both recharging an EV’s battery when electricity is at its cheapest, and discharging excess energy to sell back into the grid. 

Fleet customers will save around £350 savings per charger each year, which equates to approximately 9,000 miles of driving charge per year.

EDF’s V2G business solution includes:

  • The supply and installation of a two-way connected compact 11kW charger capable of fully charging a Nissan LEAF, depending on the battery model, in 3 hours and 30 minutes - 50 per cent faster than a standard charger - with integrated DREEV technology.

  • A dedicated DREEV smart phone app, to define the vehicles’ driving energy requirements, track their state of charge in real time, and control charging at any time

Philip Valarino, Interim Head of EV Projects at EDF, said today’s announcement marks an important step on the UK’s journey towards electric mobility. "By combining the expertise and capabilities of EDF, Nissan and Dreev we have produced a solution that could transform the EV market as we look to help the UK in its journey to achieve Net Zero," he said. “Our hope is that forward-thinking businesses across the country will be persuaded to convert their traditional fleets to electric, providing them with both an environmental and economic advantage in an increasingly crowded market.”

Andrew Humberstone, Managing Director, NMGB, said Nissan has been a pioneer in 100% electric mobility since 2010, and the integration of electric vehicles into the company is at the heart of Nissan's vision for intelligent mobility.

He added the Nissan LEAF, with more than half a million units already sold worldwide - is the only model today to allow V2G two-way charging and offers economic opportunities for businesses "that no other electric vehicle does today". Click here for more information. 

US updates

FirstEnergy Corp, which aims to electrify 30% of its approximately 3,400 light duty and aerial fleet vehicles by 2030, has joined the Electric Highway Coalition. The group of electric companies, which has grown to 14 members, is committed to enabling long-distance EV travel through a network of EV fast-charging stations connecting major highway systems.  

The Edison Electric Institute estimates 18 million EVs will be on US roads by 2030. While many drivers recognize the benefits of driving an EV, some are concerned with the availability of charging stations during long road trips. Through their unified efforts, the members of the EHC are addressing this "range anxiety" and demonstrating to customers that EVs are a smart choice for traveling long distances as well as driving around town.

Volta Industries has installed new charging stations at Safeway in Upper Marlboro, Maryland, and Renton, Washington.
