The new tariff, trademarked as Juice-E, is likely to mirror offerings from utilities companies in other territories by giving customers preferable rates if they recharge their vehicles at home and discounts for plugging in their cars at off-peak times.
Npower will launch the new tariff at the “Grand Build sponsored by VELUX” section of the Grand Designs Live exhibition that takes place from
30 April at London’s Excel.
The utilities company is likely to showcase some of the Tesla Roadster electric cars owned by Npower’s parent company RWE at the event. It is in talks with other “major motoring manufacturers” about partnerships, according to sources close to the matter. However, Tesla says it is not forming a marketing partnership with Npower in the UK.
Tesla communications manager Roberto Toro says: “We support RWE Npower as a customer and would like to see every energy company launching similar tariffs, but we will not hold preferences in terms of marketing with Npower or any other energy provider.”
The British government is offering 25% off the cost of a new electric car with its plug-in car grant but this does not currently include Tesla Roadster vehicles.
Npower markets itself online as “Britain’s greenest energy company” and already offers a home tariff, Juice, which offers customers bonuses for saving energy and supports community-based renewable projects.
A spokesman from Npower declined to comment.
