Meshcrafts has installed Norways first vehicle to grid (V2G) installation with Statsbygg, demonstrating how electric vehicle batteries can become valuable resources for the power grid and building owners. The EV battery is a distributed energy resource that can be used as an asset in the smart grid. At Statsbyggs site the EV battery stores electricity which can either be used as flexible resources in the power grid or reduce power peaks for the buildings/grid operator, as well as propulsion for the EV.
The minister of Environment and Climate, Ola Elvestuen, was invited to the first official charge and discharge of the system at Meshcrafts, which will help transform energy operations and mobility for Norway.
"This is great news and opens exciting possibilities for the future. Electric cars will be of use also when parked as an integrated part of smart energy systems" says the Minister
Meshcrafts has been part of the future Smart Grid solutions within an ongoing research and development project at Campus Evenstad under the auspices of Statsbygg.
Reducing Co2 footprint
With the objective of reducing the Co2 footprint for public buildings, Statsbygg has been researching on innovative energy technologies in collaboration with Multiconsult, how to integrate electric vehicle car batteries into the power grid. Nissan Europe delivered the two-way charging system for the project and Meshcrafts the software solution.
During a test in October, for the first time in Norway, it was demonstrated that we can transfer electricity from an electric car to the power grid.
A Nissan Leaf was connected to a 2-way charger and supplied the electric plant at Campus Evenstad with 9.5 kW of power. Meshcrafts has developed and delivered the remote control system, SmartCharge.
"With this equipment and the remote control system, SmartCharge, has demonstrated that in the long term the batteries of electric cars can be used actively as a flexible resource of the power grid. With SmartCharge the operator of the charging station can control the energy flow and peak optimize the EV charging, providing better services to the whole ecosystem" says Åsmund Møll Frengstad, founder and lead business development at Meshcrafts.
The solution installed at Statsbygg site could, for example, be used for, peak shaving during the day where the capacity of the EV power bank is utilized in cooperation with local production and the consumption of energy from EV’s and the buildings, or as an uninterruptable power supply for the buildings in case of a power outages.
The locally produced power from solar cells can charge the car during the day, while the battery in the car can supply power at night. The surplus energy from solar cells can be stored in the batteries and be used when needed to reduce baseloads and peaks, says Åsmund Møll Frengstad.
This technology has created a foundation to build upon for E-mobility to become a part of the energy vertical. This means that in the future the EV vertical can be utilized for:
- Flexible energy resources in the grid by connecting electric vehicles that will be an integrated and important asset in the power supply in the national and regional grid and energy systems. The resources can optimize operation of power grids, and postpone costly investment regarding max peak in the grid.
- Capitalizing investments for the owners of EVs and charging stations that can enable a revenue stream from existing investments by utilizing the car battery and the chargers. Changing the commodity from energy (kWh) to effect (kW) and becoming an integrated part of the power industry vertical.
