Energy management

Protect the electricity grid and support renewables with Virta’s smart energy management services.

Electric vehicles are big batteries on wheels — they offer effective balancing and storage solutions to the developing energy sector. And the best thing is that these ultimate storers of battery capacity have the ability to move around.

Our energy management features enable charging to be controlled based on different signals. This is done to protect the electrical system of a building, optimize energy consumption, stabilize distribution and transmission grids, and support intermittent renewable energy production.

Virta's energy services are available for energy companies and businesses that work closely with local energy utilities. Virta is a forerunner in providing smart energy solutions to our customers. We have a full team of energy experts and multiple ongoing development projects to take our services even further.

Together with Nissan and E.ON, we have developed a commercial V2G solution for energy and fleet customers:

Smart energy management features

Dynamic Load Management

Charging electric vehicles brings a new load to the electricity infrastructure. Multiple charging devices installed within your premises may lead to changes in the electricity system. Dynamic Load Management (DLM) is a solution that eliminates the risk of overloading and helps to evenly distribute loads between charging points. The DLM feature is already available in all Virta Charging Devices.

DLM 2.0 can be connected to all electrical devices in the building. This means that charging electric cars will just be one part of the load management of a particular location. By constantly monitoring the grid connection power used on things such as lighting and AC, the EV charging power can be adjusted so that it doesn't overpower the grid. In the near future, consumers will be expected to participate in different demand response events and manage their energy generation, loads, and storage.

Vehicle-to-Grid solutions

Vehicle-to-Grid (V2G) means communication between vehicles and the energy grid. With V2G technology, electricity can be taken from the car battery and pushed back into the grid. This enables electric vehicles to be used as part of the energy system, side-by-side with stationary energy storages and renewable energy production.

Before V2G technology becomes a reality on a larger scale, both the EV charging hardware and the electric cars themselves need to be compatible in order for charging to happen in both directions. V2G is also something that enables consumers to get involved in demand response.

We are developing our V2G solutions together with our great partners. Our first public V2G charging station was installed in Helsinki in 2017.

Optimized charging

Optimized charging means controlling the charging event automatically based on chosen signals. For instance, charging will be able to stop and start based on changes in energy production.

Virta Home is an example of a product that uses this optimization feature. Controlled by Nordic Pool Spot electricity prices, charging events are scheduled to happen during the cheapest hours of the day. Customers will be provided with an economic incentive to take part in demand response, as charging is cheaper during low consumption hours. This service is currently only available in the Nordic countries.

Optimized charging can also be implemented with other signals, such as solar or wind power production.

Frequency Containment Reserves

The grid frequency contains information about the supply and demand balance. If the balance is not maintained, the grid can suffer from power disruptions. Virta’s system enables aggregators to use electric vehicles as reserves for demand response. For instance, when grids overload and frequencies drop, EV charging powers will be brought down. The need to adjust disturbances in Frequency Containment Reserves typically occurs a few times a day and only lasts a minute or two, so it has no practical effect on the charging experience of the end-users.
