Since 2006, New Zealand’s energy sector has grappled with the legal and consent process of developing the country’s first tidal energy generation project. Tidal energy utilizes the movement of ocean currents to spin underwater offshore turbines, thus generating electricity. While smaller demonstration tidal energy schemes have been developed off of New Zealand’s coastline, none have yet provided power plant-levels of electricity before, to help offset the country’s growing energy needs.

Now, Conservation Minister Kate Wilkinson’s has finally granted approval for a large-scale tidal energy generation project in New Zealand. The contract is being awarded to Crest Energy, who will oversee the installation of up to 200 tidal turbine generators in New Zealand’s Northland Kaipara Harbour. The total area to be covered is roughly 8km by 1 km, and will generate enough electricity when finished to power “everything above Auckland—from Albany to the Cape,” according to Crest Energy Director Anthony Hopkins.

Now that the project has the green light to develop, Crest Energy is seeking investment, and predicts the first turbines to be installed within the next two years. The project in its entirety is expected to cost upward of $600 million in the first 10 years.

Investors with an interest in New Zealand tidal energy generation include the country’s wealthiest family, the Todd family.

Rumors are circulating that Irish company OpenHydro will be supplying the tidal turbines for the project.

The installation process for the tidal turbines is to be phased gradually, as to allow for testing and monitoring throughout the project’s implementation to assure that environmental concerns are addressed. Three turbines will be installed first and monitored. “I am aware of concerns raised by submitters and believe the conditions set out would ensure any possible negative impacts can be properly monitored and accounted for,” said Conservation Minister Wilkinson. A public review process will be in place that could halt the project if environmental concerns are detected.

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.
