Driving electric lorries with Infratek

One of Norway’s most important environmental initiatives, ELinGO, is rolling forward, and Infratek, with its expertise, is playing an important part in this effort to achieve more environmentally friendly freight transport. 

Driving electric lorries with Infratek

In order to survey available expertise, get feedback from partners and take the development of ELinGO to the next level, Oluf Langhelle, Professor of Political Science at the University of Stavanger, is currently travelling around the Nordic region together with Runar Søråsen of Miles Ahead AS, a consultancy firm that specialises in identifying and exploiting new business opportunities for companies using agile innovation. The first ELinGO workshop was held on 18 October 2016, at Infratek’s offices in Alnabru in Oslo.
“Infratek is an important partner in this project and our first stop on this tour,” says Søråsen. “After this, we will visit Lyse, Volvo in Sweden and the Confederation of Norwegian Enterprise (NHO) in the coming days. I am leading the subproject ‘realisation and industrialisation’ and Oluf is heading up a subproject on relevant societal parameters. An important part of our work is to document different business models,” he continues.
Freight transport is vital for business, but it is a major contributor to greenhouse gas emissions. By 2050, freight transport by road is expected to increase in Norway by 65 per cent. However, the country is aiming to become carbon neutral during the same period, which is why it is so important to work for the electrification of freight transport. This is what the ELinGO project will be researching. If everything goes according to plan, maybe they will be able to rename the new E39 between Kristiansand and Trondheim the “EL39” when it is completed in 2035.
The ambition is to electrify the whole 1,100 km route, and there are several options on the table as potential solutions, such as inductive charging of vehicles on the road, overhead wires combined with pantographs mounted on the cabs of heavy goods vehicles and buses, or an electrified rail along the road (physical charging). All of these options would allow heavy goods vehicles to recharge as they drive. 
“Regardless of which option is selected in the end, Infratek will be an important partner, just as they are today. But it could also mean contracts for deliveries,” says Søråsen.
In Q1 2017, a report will present the results of the subprojects that are being led by Professor Langhelle, who adds: “Apart from freight transport, nearly all industries are managing to lower their emissions. That makes this project extremely important for the sector.”
Jarle Pettersen, Division Manager at Infra Solutions, believes it makes a lot of sense for Infratek to get involved in the project. “No one in the Nordic region is building more charging stations than we are. We have expertise in this field, and ELinGO can both lead to new contracts and provide us with insight into this massive future market – not immediately, but over the long term and into the bright future ahead of us,” he asserts.
The ELinGO project will be implemented in partnership with companies that are looking to get on board with the electrification of road freight transport. The Norwegian Public Roads Administration is the project owner, while SINTEF Building and Infrastructure is responsible for the day-to-day coordination of the project. The project is funded with grants from the Research Council of Norway.
Infratek is one of 11 partners (companies) involved in the project, which also includes Siemens, Volvo and the Norwegian University of Science and Technology.

Tunnel breakthrough for Infratek

Infratek will be responsible for electrotechnical installations in the new tunnel on the E16 road between Sandvika and Wøyen in Bærum municipality. This is Infratek’s first tunnel contract.

 Tunnel breakthrough for Infratek

“We won on price, which was the sole criterion, and the value of the contract with the Norwegian Public Roads Administration is NOK 20.59 million,” reports Jarle Pettersen, who is the company’s division manager. Infratek’s Infra Solutions division will be responsible for the work.

“This is a big day for us. We are entering a new market, a market that is in rapid growth. With this contract, we are showing that Infratek is now also competitive in this area. This project gives Infratek a new dimension. We can literally see the light at the end of the tunnel,” Pettersen says.

The contract concerns the supply and performance of electrical installations for the Bjørnegård tunnel and associated barriers in the daylight close to the tunnel portals. The tunnel consists of two bores, with two lanes in each bore. There are also three technical constructions.

The Bjørnegård tunnel is a 2.3 km two-bore tunnel that constitutes part of the new E16 in Sandvika. The traffic will be considerable, and so will the extent of the technical installations. The electrical job includes the supply and installation of 88 km of cabling, three main distribution boards and three UPS systems. (An Uninterruptible Power Supply, or UPS, is a backup system that ensures the vital functions in the tunnel continue to work in the event of main power failure.)

Infratek will also install and connect a total of 1,653 light fittings in the tunnel, along with 48 fans. The deadline for completion of both assignments has been set to 13 December 2019.

Grid owners can save NOK millions

Infratek are experts in live working. This working method means large savings for grid owners and more stable power supplies. “We could be looking at annual savings of up to NOK 10 million in costs of energy not supplied,” states Arild Borge, department manager for Norgesnett.

Grid owners can save NOK millions

 “Much of this cost is due to disconnections for scheduled work. Live working means a considerable reduction in power disconnections, which of course means more satisfied customers,” he continues.

On the island of Asmaløy in Hvaler municipality in southern Norway, a line disconnect switch has jammed in the 20 kV distribution network. Norgesnett faces the choice of disconnecting the power for thousands of homes and holiday cabins further out in the Hvaler archipelago, disconnecting extensive sections of the high-voltage grid, or using live working to correct the fault.

“Many people use their cabins out there as remote offices over the long weekends, with PCs and other equipment that need power,” explains Borge. “Both those customers and the permanent residents need to be notified in the event of a planned power outage. And even though we do provide a warning, individual customers can understandably become irritated. A lot of them phone up Customer Services, and it has a negative effect on our reputation. One important factor is that we also face increased costs for energy not supplied. Besides, live working methods are at least as efficient. At Norgesnett, we have now really put live working on the agenda, and we will definitely be using this expertise much more in the future,” he emphasises. Together with his team, Borge is able to observe the repair work on the switch on Asmaløy close-up, as Infratek’s engineers drive the four-wheel-drive truck with its cherry-picker along the rocky shore.

Engineers Erlend Teig and Lindulf Gaustad give a step-by-step explanation of the work to those present. The duo leave no doubt: safety first. “It’s all about controlling the risk factors,” explains Erlend Teig. 

The REN (“Rational Electricity Grid Operations”) organisation is holding workshops on live working on 20 and 21 September at Gardermoen. Infratek will be taking part to demonstrate the technique. Infratek is one of the few companies with extensive experience of the working method.

“The personnel we use for live working, such as Erlend and Lindulf, are highly experienced, and they have extensive training and a fundamentally sound level of technical expertise,” confirms Kjell Løvbakken, department manager for Infratek. “Without the right know-how, this is a challenging and hazardous job. We take on live working assignments whatever the accessibility or terrain. It’s vital to have all the right equipment and to be fully trained in how to use it. A lot of live working installers say that they actually feel safer when working live, as then all of the risk factors are under their control. Statistics from various countries where live working is more common than in the Nordic region also confirm that live working actually is a safer working method than working on disconnected equipment,” he states.
Another advantage of live working is that it ensures full redundancy in the power grid. 

Norgesnett AS is a wholly-owned subsidiary of Fredrikstad Energi AS, and, through its area concession, is responsible for the power grid in the municipalities of Fredrikstad (excluding Onsøy), Hvaler, Nesodden, Røyken, Enebakk, Ski and Askøy. Norgesnett has approximately 93,000 customers.
