When EV sales continue to rise and the overall targets for carbon emissions become more ambitious, energy system stakeholders will have to consider flexibility alternatives from, among others, EV charging. A large distribution system operator in the UK is now investigating the options for rewarding customers to customize the EV charging pattern to load profiles in the network. If successful, the exercise can help reduce the cost of network infrastructure expansion.
The increasing number of electric vehicles on roads had once been called a serious concern for network operators, which charging for certain hours could easily overstress the network. Quickly, a win-win solution was found for the EV and Renewable Charging industry, which enables instant charging of cars.
The UK-based power producer UK Power Networks has launched a trial to handle smart charging patterns via a market-driven approach for the first time in the country. In a lawsuit called Shift, the company offers financial incentives to 1,000 electric vehicle owners to charge their cars without working hours.
In an announcement, the UK Power Networks said the "options are either to spend their customers' money on building new infrastructure to meet this growing demand or to smarter in order to avoid it. "
For this trial, energy technology provider Octopus Energy, intelligent energy platform Kaluza, from the OVO Group, and charging point operator Pod Point will work to develop business models and market mechanisms to enable smart charging, ultimately rolling out a solution across the country.
In the beginning, the companies involved will recruit 1,000 members of the public who own an electric vehicle and charge it at home in the business areas of the UK Power Networks, the London area and the South and East of England.
“We are very happy to work with our customers and industry on a nationally significant tri all this can revolutionize the electric automotive industry,” says Ian Cameron, United Kingdom's Power Networks Innovation Manager. "There has been a lot of talk about how smart charging can save customers money and help manage the network, but this is the first time we actually plan to discover how."
The project may be directly needed, UK network operator National Grid recently published its Future Energy Scenario report. In the network, the network operator claimed that in order for a net zero carbon economy to be possible by 2050, significant capacities in smart charging must be unlocked. According to the authors, an 80% CO2 reduction target requires a baseline from 1990, a similar amount of renewable energy and electrification. For the last 20% of the reduction, legislators and network operators must make use of flexibility alternatives in response to the demand side, smart charging and vehicles on the net – on a scale. National Grid expects 65% of EVs on Britain's roads to use smart charging.
Aside from the benefits to the web, the Institute for Energy Economics and Financial Analysis (IEEFA) investigated what other benefits could arise for customers from the exercise in their Electric Vehicles and Batteries May Lead to Solar Plant Growth in May . In the UK, with the current low VAT rate regime for solar products, the payback time for a stand-alone solar system is estimated at 19 years, with an annual return on investment of -2.7%.
According to this study, the combination of EVs and solar systems could reduce the expected repayment period to nine years, with a return on investment of 0.9%. The combination of EV battery storage and a sunroof creates an even stronger financial case for the UK, which calls for a payback period of just four years.
