The residential Battery-Powered Electric Vehicle (BEV) market is growing at an exponential pace in Europe, with Germany, France and the UK leading the way. This whitepaper from Delta-EE's New Energy Business Model Service describes how the booming uptake of BEV is creating significant opportunities for energy actors. It also assesses the current state of the EV tariff-based proposition market and finds that, even though the scale of the opportunity is widely recognised, the level of innovation to date has been limited and there remains plenty of room for disrupters to enter the market.
