For three years, Charlotte Blou Sand and True Energy have made it possible for owners of electric cars to charge their vehicles using a smart, green method, while, at the same time, being able to use many thousands of car batteries to stabilize the power grid.
It is a recurring mantra in the modern world of electricity that the key factor is when power is used. Sometimes it is even more important than how much power you use, even if the latter notion might still make some energy savers perish at the thought.
For Charlotte Blou Sand, timing has become a way of life. When she leased her first electric car, a Renault Zoe, in 2016, the then 42-year-old digital aficionado and mother of three quickly found out that it was both expensive to charge the car and nigh impossible to do it in a green and smart way.
In 2018, Charlotte founded True Energy as an electricity trader with an ambition to create an app allowing electric car drivers to define their individual preferences themselves. This might be, for instance, how much power the battery should have at 8 am and whether the car should be charged when the power is cheap or green, two factors which often, but don't always coincide.
