Technology
TRL (formerly Transport Research Laboratory) lists three power delivery types for dynamic charging, or charging while the vehicle is in motion: overhead power lines, ground level power through in-road or on-road rail, and wireless inductive charging. Overhead power was most technologically mature solution which provided the highest levels of power at the time of the 2018 report, but the technology is unsuitable for non-commercial vehicles. Ground-level power is suitable for all vehicles, with rail being a mature solution with high transfer of power and easily accessible and inspected elements. Inductive charging delivers the least power and requires more roadside equipment than the alternatives.{{rp|at=Appendix D}} By the late 2010s, infrastructure costs of ground-level rail became lower than overhead lines.{{Rp|21–24}}

The first permanent electric road in Sweden was as of 2023 planned to be built on a section of the E20 route between Hallsberg and Örebro. The E20 project was funded at 500-600 million SEK, or about 24-29 million SEK per two lane-kilometers. The procurement process was cancelled as the submitted offers by Electreon and Elonroad exceeded the project's budget. The procurement process was expected to begin again by the end of 2025, but the project's final report submitted in December 2024 recommended against a national electric road network in Sweden as it would not be cost-effective, and the project was paused.
== Siemens ==
Overhead power lines were first tested through the program, using Siemens eHighway technology. The system was inaugurated in June 2016 in Sandviken municipality near Gävle in central Sweden. A 2-kilometre stretch of the E16 motorway was fitted with trolley wires 5.4 metres above its surface, which supply power at 750 volts DC. Trolleytrucks can connect the power pickups, mounted on mechanical arms or trolley poles, while driving under the wires. The trolley poles allow for a degree of lateral movement, but if the lorry is steered into the outside lane, the trolley poles are lowered automatically and the lorry switches to battery or diesel power.{{citation|url=https://www.trafikverket.se/en/startpage/about-us/news/2016/2016-06/first-electric-road-in-sweden-inaugurated/|title=First electric road in Sweden inaugurated|publisher=Swedish Transport Administration|date=June 22, 2016}} The system as tested is capable of delivering 500 kW of power and has an estimated maintenance period of 20 years.{{Rp|140–144}}

Travikverket estimated in 2020 that other-than-damage maintenance costs are highest for either of the two rail systems, second highest for overhead lines, and lowest for induction.{{citation |title=Vägunderhåll och kostnader för olika typer av Elvägar |publisher=Trafikverket |author=Krister Palo |date=September 15, 2020 |url=https://bransch.trafikverket.se/contentassets/e65ff31b80fd4d3bbfc37de7660896c3/vagunderhall-och-kostnader-for-olika-typer-av-elvagar---rapport.docx.pdf |page=5}} Total annual maintenance costs were estimated in 2021 by the technology providers to be, in terms of percentage per year of the initial capital costs, 0.5% for rail, up to 1% for induction, and 1%-2% for overhead lines.{{citation |url=https://www.youtube.com/watch?v=I5xdJMoz_WA |archive-url=https://ghostarchive.org/varchive/youtube/20211222/I5xdJMoz_WA |archive-date=2021-12-22 |url-status=live|title=Electric Road Systems - PIARC Online Discussion |author=PIARC |date=February 17, 2021 |at=34 minutes 34 seconds (standardization), 2 hours 36 minutes 51 seconds (standardization), 2 hours 35 minutes 25 seconds (maintenance)}}{{cbignore}} A 2022 paper estimated yearly repair and maintenance cost per kilometer at 16,000 USD for overhead lines, 11,000 USD for in-road rail, and 33,000 USD for inductive coils.{{Rp|12}}
==Annualized societal cost==
===2019 report===
A 2019 report by the Swedish Electromobility Centre estimates the annualized societal costs of the entire Swedish automotive fleet under each of the three power delivery systems. Each of the systems was found to result in net savings, with the rail system being the most beneficial.{{citation |url=http://emobilitycentre.se/wp-content/uploads/2019/09/Power-Conversion-Challenges-with-an-All-Electric-Land-Transport-System.pdf |title=Power conversion challenges with an all-electric land transport system |author=Francisco J.

Overhead power lines, despite being the most mature technology and, at the time of the 2019 report, having the least expensive infrastructure, are the most expensive overall because they only allow tall commercial vehicles such as trucks and buses to charge while driving, while non-commercial vehicles cannot use the wires to charge while driving, so they will have to use static charging that requires larger batteries with higher capacities than batteries required with the use of dynamic charging. Though overhead lines had the least expensive infrastructure costs when the initial report was written,{{rp|10–11}} soon afterward infrastructure costs of ground-level rail became lower than overhead lines.{{citation| author=Guerrieri, M. |title=Catenary-Free Tramway Systems: Functional and Cost–Benefit Analysis for a Metropolitan Area. |journal=Urban Rail Transit |issue=4 |pages=289–309 |year=2019 |volume=5 |doi=10.1007/s40864-019-00118-y|s2cid=208953068 |doi-access=free |hdl=11572/246245 |hdl-access=free }}{{Rp|21–24}}
Ground-level power supplies allow dynamic charging for all vehicles, which greatly reduces the required battery capacity and size since the battery is charged while it is being used. The reduced battery size and capacity reduces cost by about five billion euros annualized for the entire Swedish automotive fleet. The rail and inductive systems are estimated to have equal annualized costs for all components in aggregate other than infrastructure; the conductive rail infrastructure is estimated to cost about 1 billion euros annualized, while wireless inductive infrastructure is estimated to cost about 2.8 billion euros annualized.{{rp|10–11}}
The Swedish Transport Administration's regulations for state electric roads proposed in 2021 include estimates for different charging system costs for the customer driving different types of electric vehicles. Long-haul and regional haul trucks were found to incur the least costs with fast charging stations, though the conditions for such a fast-charging network are not currently met and it's not clear if they can ever be met,{{Citation | vauthors=Börjesson M, Johansson M, Kågeson P | year=2021 | title=The economics of electric roads | journal=Transportation Research Part C: Emerging Technologies | volume=125 | page=102990 | doi=10.1016/j.trc.2021.102990 | s2cid=214702482 | url=http://dx.doi.org/10.1016/j.trc.2021.102990| doi-access=free }} while passenger vehicles were found to incur the least costs with electric road charging.{{citation |title=Regler för statliga elvägar SOU 2021:73 |url=https://www.regeringen.se/4a5530/contentassets/37e1f87a819e48ff9c79d615ff8fd8ec/sou-2021_73.pdf |archive-url=https://web.archive.org/web/20210902072110/https://www.regeringen.se/4a5530/contentassets/37e1f87a819e48ff9c79d615ff8fd8ec/sou-2021_73.pdf |archive-date=September 2, 2021 |date=September 1, 2021 |publisher=Regeringskansliet (Government Offices of Sweden) |pages=291–297}}
===2024 report===
The project's final report submitted in December 2024 recommended against a national electric road network in Sweden as it would not be cost-effective. The annualized societal costs from 2040 to 2070 were found to be higher than the benefits, with a robust degree of certainty.{{Rp|52–58}} Subsequently, Trafikverket decided to pause the project.
Planning
The switch from the assessment phase to the planning phase was estimated to occur in 2022,{{rp|40}} but the Swedish government accelerated the program's schedule, and began the planning phase with the creation of the electrification commission in October 2020. The commission investigated the electrification of heavy transport vehicles, fast charging, and the standardization, construction, operation, maintenance and financing of electric roads in Sweden. A report on the chosen electric road infrastructure was expected by September 2021,{{citation|url=https://www.regeringen.se/regeringens-politik/transportsektorn-elektrifieras/planering-for-elvagar-och-snabbladdning/|title=Planering för elvägar och snabbladdning|date=October 15, 2020|author=Government Offices of Sweden}} but the choice was delayed until late 2022 or early 2023,{{citation |url=https://www.trafikverket.se/contentassets/f64614c766c34d59ae95747f90aeaf8a/elektrifiering-av-tunga-transporter_nathanaelsson.pdf |archive-url=https://web.archive.org/web/20220302080542/https://www.trafikverket.se/contentassets/f64614c766c34d59ae95747f90aeaf8a/elektrifiering-av-tunga-transporter_nathanaelsson.pdf |archive-date=March 2, 2022 |title=Elektrifiering av transportsystem |author=Kenneth Natanaelsson |publisher=Trafikverket |date=March 26, 2021}}{{citation |url=https://www.youtube.com/watch?v=bEdcdsLC88Y |title=Electric Road Systems - PIARC Online Discussion |date=November 4, 2021 |section=Rebecka Johansson, Ministry of Infrastructure - ERS Regulations, policies and strategies in Sweden |at=14 minutes 25 seconds into the video}} then delayed again to mid or late 2023, and eventually scheduled for December 2024.{{citation |author=Energimyndigheten (Swedish Energy Agency) |date=January 2023 |title=Delrapport inom uppdraget om handlingsprogram för laddinfrastruktur och tankinfrastruktur för vätgas |page=20 |url=https://www.energimyndigheten.se/remissvar-och-uppdrag/Download/?documentName=Delrapport%20inom%20uppdraget%20om%20handlingsprogram%20f%C3%B6r%20laddinfrastruktur%20och%20tankinfrastruktur%20f%C3%B6r%20v%C3%A4tgas.pdf&id=1877}} Regulations for electric roads, independent of the chosen technology, were proposed on September 1, 2021. The final report on the expansion of the Swedish electric road network was published in December 2024. It recommended against a national electric road network in Sweden as it would not be cost-effective unless it was part of a larger network with France and Germany. Following the report, the project was paused.
Construction and operation
= Legal aspects =
The Swedish Transport Administration anticipates that a national electric road network would require interfaces between several players: the electricity supplier, the power grid company, the vehicle manufacturer, the road owner, the electric road technology operator, the metering and billing provider, and the user of the electric road. The ownership model can vary: the power grid company may own the secondary roadside electrical substations that power the electric road infrastructure or they may be owned by other players, and the power reading and payment system may be owned by a player separate from the infrastructure operator.{{citation|url=https://www.entelios.se/globalassets/los-energy2/entelios-innhold/hasselgren-ers-systems-in-sweden-191010.pdf|title=Swedish ERS - program background, current analysis phase and plans ahead|date=October 9, 2019|author=Björn Hasselgren|publisher=Swedish Transport Administration}}{{Rp|10–11}} ABB formed a consortium that will handle the different aspects of the business model, such as energy metering and billing, for its ground-level power supply technology.{{citation |url=https://twitter.com/ABBNorge/status/1425355476817096705 |title=Vi er med på bygging av første permanente el-vei for #tungtrafikk, i Sverige: E20 mellom Hallsberg og Örebro, 21 km, klar i 2025Delivery truckHigh voltage signSmiling face.

==Proposed framework==
The Swedish Transport Agency has been tasked with proposing a technical, financial, and legal framework for the electric road toll system by November 1, 2022.{{citation |url=https://www.regeringen.se/pressmeddelanden/2022/03/uppdrag-till-transportstyrelsen-att-foresla-ett-avgiftssystem-for-statliga-elvagar/ |date=March 24, 2022 |author=Swedish Ministry of Infrastructure |title=Uppdrag till Transportstyrelsen att föreslå ett avgiftssystem för statliga elvägar |access-date=March 24, 2022}} The agency proposes expanding the legal framework of the Stockholm congestion tax for electric road permits, and rolling out the technical framework in stages. For the first permanent electric road the Agency will offer fixed-fee permits for use of the electric road system. As the system gains more users, it will transition to usage-based billing. The infrastructure, along with equipment installed on registered vehicles, will verify the permit and the standing of the permit holder's debts and payments, then allow or disallow drawing power from the electric road system and bill the permit holder appropriately.{{citation |url=https://www.transportochlogistik.se/20221109/15899/forenklat-avgiftssystem-statliga-elvagar |title=Förenklat avgiftssystem för statliga elvägar |author=Peter Höök |date=November 9, 2022|website=transportochlogistik.se}}{{citation |url=https://www.transportstyrelsen.se/sv/Press/Pressmeddelanden/2022/nytt-avgiftssystem-for-att-ladda-fordon-pa-statliga-elvagar/ |title=Nytt avgiftssystem för att ladda fordon på statliga elvägar |last1=Geidne |first1=Jonny |publisher=Transportstyrelsen|date=November 2022}}

The Swedish Transport Administration announced on July 1, 2021, that a section of the E20 route was chosen to be the first permanent electric road in Sweden.{{citation |url=https://www.trafikverket.se/nara-dig/projekt-i-flera-lan/elvag-nynashamn-eller-orebro/nyheter-for-pilotprojekt-elvagar/sveriges-forsta-elvag-byggs-mellan-orebro-och-hallsberg/ |author=Swedish Transport Administration |date=July 1, 2021 |title=Sveriges första elväg byggs mellan Örebro och Hallsberg}} The road was expected to begin operation by 2027. Before the project was paused in 2024, an expansion of further 3000 kilometers of electric roads was expected by 2045.{{citation| url=https://www.nyteknik.se/fordon/sverige-pa-vag-att-bli-forst-med-elvagar-rullar-ut-ganska-snabbt-7020044 |title=Sverige på väg att bli först med elvägar – Rullar ut ganska snabbt |author=Jonas Grönvik |website=Ny Teknik |date=September 1, 2021}}
The first permanent electric road in Sweden was as of 2023 planned to be built on a section of the E20 route between Hallsberg and Örebro.{{citation |url=https://www.malardalsradet.se/steg-for-steg-i-elektrifieringen-av-transporterna/ |author=Kenneth Natanaelsson |title=Elväg Örebro-Hallsberg, Infradagen 2023 |date=March 17, 2023 |website=Mälardalsrådet}} An analysis by the logistics firm Novoleap concluded that the electric road on the E20 section between Hallsberg and Örebro will result, for logistics companies, in reduced capital costs for electric fleets, reduced operating costs, and reduced {{CO2}} emissions. Novoleap notes that the total cost of the electric road may be positive or negative depending on its capital costs for infrastructure, its annual maintenance costs, and its delivered power per vehicle; 200 kW of power per truck is adequate, but higher levels of power such as 400 kW and 800 kW are more beneficial and might be required in the long term.{{citation |url=https://utveckling.regionorebrolan.se/globalassets/media/dokument/regional-utveckling/samhallsplanering-och-infrastruktur/electric-road-pilot-e20-hallsberg-orebro.pdf |archive-url=https://web.archive.org/web/20220111095114/https://utveckling.regionorebrolan.se/globalassets/media/dokument/regional-utveckling/samhallsplanering-och-infrastruktur/electric-road-pilot-e20-hallsberg-orebro.pdf |title=Report electric road Region Örebro County |author=Henrik Wallström |date=June 5, 2020 |archive-date=January 11, 2022 |accessdate=January 11, 2022 |pages=17–19, 49, 61}} The VTI similarly recommends a system capable of delivering 300 kW per truck. The Swedish Transport Agency has proposed in late 2022 the billing framework for the first permanent electric road, which will initially rely on a permit for a fixed fee. As the system gains more users, it will transition to usage-based billing.
