Why Tempus is smart charging electric vehicles in Europe
Industrial processes are going electric. This is great because with electrification comes the ability to choose your energy mix - and why not choose renewables? We’re not talking about ‘green tariffs’ which offset usage with purchases of renewable energy - we’re talking about real time data that can optimise your use of renewable energy when it’s available.
A big challenge for renewable energy is intermittency - this means that when there’s no wind or sunshine they don’t produce electricity, causing fossil fuel power stations to ramp up and meet demand to keep the grid balanced. Therefore the carbon intensity on the grid varies throughout the day. Carbon intensity is a measure of how much CO2 emissions are produced per kilowatt hour of electricity consumed.
Most people have been unaware of this fact for a long time as there was no viable alternative. But, as new technologies are developed and data collected, we now have the ability to forecast carbon intensity as we do the weather.
Not only can we now understand the carbon intensity of our grid mix, but we can control and automate when energy is used; aligning energy demand to match these times of low carbon intensity - when the wind blows and the sun shines. We call this demand flexibility.
Demand flexibility releases us from our reliance on fossil fuel as a back-up to peak demand.
One simple, but highly effective use of this technology is to align electric vehicle (EV) charging with these low carbon periods. An EV may only need 4 hours for a full charge, but is plugged in for 12 hours. You can ensure your charging time has the lowest carbon intensity available.
Due to low operating costs renewable energy is also the cheapest energy to generate - once you take intermittency out of the equation they are the perfect energy source of a future clean grid.
Tempus has been working with large business customers in Australia to fully automate this process, demonstrating that a ‘behind the scenes’ model can have no impact to operations while reducing carbon and saving money. We have achieved carbon and price savings of over 25%.
After demonstrating exceedingly positive results from this trial we are now partnering with Alelion in Europe who will use our demand flexibility technology to create smart charging forklift trucks and reduce the carbon footprint of their customers.
