Nexans Climate Day 2022

Key stakeholders discussed offshore wind farms and U.S. energy independence

  • Nexans hosted its third annual Climate Day in New York City on September 21 as part of Climate Week NYC.
  • Executives from the energy sector debated the future of offshore wind in the U.S. and how to build a supply chain that can support the energy transition.
  • Actor and environmentalist Adrian Grenier opened the event with a fireside chat on ocean conservation.

Nexans hosted its third annual Climate Day in New York City this afternoon with executives from the energy space including Siemens Gamesa, the American Clean Power Association (ACP), Citizens for Responsible Energy Solutions (CRES), Equinor, the American Council on Renewable Energy (ACORE), Ørsted, Marmen, and the Business Network for Offshore Wind (BNOW).

In a world where energy has been at the center of the conversation, this event in which ideas could flow freely, was crucial to the development of actionable solutions to the energy crisis.

One key takeaway highlighted by Nexans CEO Christopher Guérin was that “The reserves for raw materials are not infinite. The consumption of copper in the world went from 9 million metric tons to 21 million metric tons in the last 25 years. With the world becoming more electrified than in the past and because of the addition of electric vehicles, in 10 to 15 years, the demand will increase to 35 million metric tons. The only way to support to support investments in sustainable energy is through the recycling of raw materials and to increase innovation.”

The event also featured a fireside chat about ocean conservation with actor and environmentalist Adrian Grenier and remarks from Congressman Andrew Garbarino (NY) and Senator Ed Markey (MA), as well as panels debating whether offshore wind can help solve the energy crisis and what the supply chain will look like in the United States for more sustainable sources of energy.

Some key takeaways from the day include:

  • We can only achieve our goals if companies, policymakers, and governmental agencies work together with one objective: to make change and move toward a more sustainable future, today. These are challenges we face together, and we must culminate our individual efforts to ensure change while keeping costs low.
  • Elected officials hope to localize the supply chain to meet their sustainability goals, create jobs and support the local economy while at the same time ensuring the security of the electrical grid. The Inflation Reduction Act empowers businesses to make decisions that are necessary to expand offshore wind operations in the United States.
  • Actor, filmmaker, and environmentalist Adrian Grenier noted that, “There’s an artificial timeline that has been imposed. We need to be reliant and take responsibility to make these positive changes. Let’s put more resources, more minds, and more energy into what we can build without the constrains of fear and time.”

Nexans strengthens its long-standing partnership with Eiffage for the energy transition and the electrification of the future
Partnership
06 July 2022
3 min

Nexans has signed a three-year partnership agreement with Eiffage. The Group has been approved to supply charging stations for electric vehicles at Eiffage’s 1,000 French sites, representing more than 4,000 charging points.

After 20 years of successful collaboration, Eiffage renews its trust in Nexans for the supply of charging stations.

Nexans’ AGICITY range, produced at its Donchery site in the Ardennes region of France, offers compact charging stations that can be customized for indoor and outdoor car parks, including numerous services and options for integrating high-performance digital solutions.

The AC and DC charging stations supplied by Nexans operate at between 22-50 kVA, allowing two cars to charge at the same time. A 45-minute charge gives up to 80% of the electric range, depending on the vehicles and the power of the station.

An initial project overseen by Nexans to equip the Eiffage head office in Vélizy Villacoublay with 200 charging points was successfully completed in 2021.

With these developments, Nexans is once again displaying its industrial agility and its capacity to support its customers in their energy transition.

We are very proud of the trust that Eiffage places in Nexans. This partnership enhances our collaboration even further, offering exciting development prospects in the rapidly expanding EVCI market. It also demonstrates the commitment of our two groups to the energy transition.

Jean-Louis Tisnes

France Sales Director for the Electric Vehicle Charging Infrastructure (EVCI) activity, Nexans

Nexans’ expertise, the quality and reliability of its French-manufactured products, and the quality of the long-term collaborative relationship were decisive factors in our decision to confirm Nexans as a supplier to equip our 1,000 sites with electric vehicle charging stations.

Patrick Harter

Purchasing Director, Eiffage

Since 2014, Nexans has been designing and manufacturing electric vehicle charging stations that integrate management and supervision services. It has already delivered more than 20,000 charging points in France, supporting the collective effort to reduce CO2 emissions.

Nexans hence confirms its broader goal of creating the electricity of tomorrow and being a player in the construction of a low-carbon Europe.

This ambition follows on from actions already undertaken with Eiffage, in particular in the development of solar energy – an area that has seen continual growth since the inauguration of the Cestas photovoltaic power plant in 2015, the largest in Europe at the time (300 MWc of installed power producing the equivalent annual consumption of 150,000 households).

Given that 40% of global energy-related CO2 emissions come from the electricity sector, primary energy sources must move towards renewable energy. Solar power, for example, currently accounts for around 2% of the French energy mix. However, this sector is expected to see exponential growth, and is now a priority investment for the planet.

Nexans is also working to bolster the competitiveness, reliability and sustainability of solar power – one of the key solutions for the electrification of the future, as well as the use of electric vehicles.

Eiffage and Nexans have a long-standing partnership working closely together in the energy transition markets through the sale of LV/MV cables and accessories for public energy networks and renewable energy projects, particularly solar.

A world-first in France at Montparnasse train station: Nexans installs superconducting cables to strengthen and secure the power supply
Project
09 June 2022
5 min
Paris Montparnasse train station
  • An unprecedented partnership with France’s State-Owned Railway Company (SNCF Réseau): these will be the first superconducting cables in France, and the first of their kind to be integrated into a rail supply network anywhere in the world.
  • Nexans’ superconducting cables will help secure the electricity supply to the Paris Montparnasse sector.
  • Drawing on their unrivalled experience in this field, the Nexans teams will design the cable that will be tested in the SNCF Réseau laboratory in Vitry-sur-Seine before installation at Montparnasse next year.

Together with its partners, Nexans won a project from Bpifrance (French Public Investment Bank) under the “Investissements d’Avenir” (Investments for the Future) initiative coordinated by SNCF Réseau for the installation of two superconducting DC cables near Montparnasse station in Paris. This is the first time that cables of this type will be integrated into a rail network and is set to be the first permanent installation in France on any network. With their revolutionary technology, these power cables will help secure the network at a time when rail traffic is constantly growing in mega-cities.

Built in 1840 in Paris, Montparnasse is France’s fourth-largest train station, with more than 50 million passengers annually and more than 90 million expected in 2030. SNCF Réseau will thus need more power to run an ever-increasing number of trains. And superconductor cable technology will help provide the increased electrical power required to meet the needs of this growing rail traffic.

In this key project for SNCF Réseau, superconducting cables will make use of Montparnasse station’s infrastructure by installing the cables in existing conduits. Only a superconducting cable can combine a reduced diameter and exceptional power to deliver the performance required by SNCF Réseau: 5.3 MW per conduit, or 3,500 A to 1,500 VDC. This also enables our customer to save on substantial implementation costs related to infrastructure modification, avoid potential disruptions to rail and road traffic, and limit risks in terms of execution time and the commissioning date.

Superconducting power cables offer unparalleled advantages. As they have zero resistance, they transport electricity with minimal power loss and thus contribute to making the world more sustainable. This project illustrates perfectly how their compact nature enables them to transport very high power through a limited space. A single superconducting cable can replace multiple copper cables. Also, it has a minimal footprint, making high-capacity 1,500 V connections possible, which in turn improves the safety of the stations’ power supply.

This is a world-first that we are proud of and happy to be bringing to life with the SNCF Réseau following a productive partnership. Superconducting cables offer commercial solutions to strengthen high power electrical networks in all urban areas around the world. They are part of a technology of the future developed by Nexans and offer an extremely efficient solution benefiting companies and the general public.

Christopher Guérin
Christopher Guérin

CEO, Nexans

SNCF Réseau is delighted to be able to innovate and benefit from Nexans’ expertise to modernise and strengthen the electricity supply to the major train stations, allowing us to secure and improve the service provided to our customers. Developing this superconducting cable technology should enable us to achieve cost and deadline reductions. Likewise, it is proof of our teams’ know-how. We also thank Bpifrance for its financial support!

Frédéric Michaud

Deputy General Manager of Industrial Projects & Engineering, SNCF Réseau

Two cables connecting the Vouillé substation to the overhead lines of the tracks serving Montparnasse will be commissioned in 2023.
