The vans, supplied through local Nissan dealer Wessex Garages, have replaced a fleet of aging Citroen diesels.
Together, they will help the council save around £8,000 per year on fuel and make a contribution towards the borough's carbon reduction targets.
The council also expects to make maintenance savings, with the e-NV200's all-electric drivetrain making burnt out clutches and malfunctioning starter motors – commonplace with diesel multidrop delivery vans – a thing of the past.
"These vans offer a win-win situation for the council," comments councillor Anthony Hunt, deputy leader of Torfaen County Borough Council.
"Firstly, we expect to make fuel savings of around £8,000 per vehicle, per year, which is a major benefit for the residents of Torfaen at a time when budgets are tight.
"Secondly, the vehicles will have a significant impact as we look to reduce our carbon emissions and improve air quality in the county."
Launched last year, the Nissan e-NV200 combines the NV200 – a former International Van of the Year – with technology from the Nissan LEAF electric car.
Nissan claims that it costs two pence per mile to run while cost of ownership is £2,500 lower than a conventional diesel over three years.
Additionally, this model, which is priced from £13,568 in panel van form (incorporating Government Plug-In Van Grant), offers 4.2m3 capacity and a 703kg payload.
