Power included – calculable costs
Our sister company Ventus Energy GmbH supplies our customers with electricity from our own wind and solar farms. This means prices can be calculated in the long term and enables climate-neutral operation of the e-buses.
Renewable energies must be stored so that they are available at all times. eMIS makes the batteries of the e-buses usable for this task. As soon as a bus is at the charging point, it can feed the remaining capacity of its battery into the power grid. This bidirectionality (aka Vehicle2Grid) supports the grid and enables the operator to participate in the energy market.
The eMIS charging management also prevents batteries from being charged during peak load periods. It charges the buses one after another, depending on the re-use schedule, as soon as the electricity is cheaper. The system learns how each bus is used. It never fully charges the batteries, which increases their lifespan.
As one of the first companies in Germany, eMIS does not supply system modules, but complete bidirectional solutions. Only with eMIS public transport bus operators are able to benefit from the full economic potential of this technology.

Partners of eMIS
eMIS Deutschland GmbH has taken the leading role in managing and structuring the project ‘Developing and implementing a sustainable, innovative system integration project for sector coupling of transport and electricity’. Their work on this joint project is being complemented by cooperation or collaboration with experienced partners:
Enercon GmbH is one of the leading manufacturers of wind energy systems. Headquartered in Aurich, East Frisia, the company can draw on more than 30 years’ experience in the renewable energy industry. In addition to their core business field of wind power systems, Enercon is also a system provider for the supply of renewable energy, promotes solutions for integrating them internationally, and is involved in forward-looking technologies such as energy storage, electromobility and smart grids.
The Ludwigslust-Parchim Transport Company GmbH (VLP) operates the public passenger bus network in the Ludwigslust-Parchim district and in Amt Neuhaus, in the district of Lüneburg. At present VLP operates a regular service with around 200 buses on 172 routes. VLP covers the entire value chain from transport planning, control and provision to maintenance, repair, cleaning and refuelling of the buses.
Based in Schwerin, Mecklenburg-Vorpommern, Wemag AG is a nationally active supplier of eco-friendly energy with regional roots in Mecklenburg-Vorpommern and Brandenburg. Besides electricity, natural gas and grid services, the energy company provides its customers with a range of services that includes planning and constructing photovoltaic and storage facilities, and electromobility. Wemag AG is involved in the project through its technical innovation/storage technology and energy procurement/marketing departments.
As operator of the regional grid in western areas of Mecklenburg-Vorpommern and parts of Brandenburg and Lower Saxony, Wemag Netz GmbH provides the necessary infrastructure for receiving, transmitting and distributing electricity. It is a subsidiary of Wemag AG. The grid serves an area of around 8,000 km2, and the total length of the power lines is around 15,000 kilometres. The Wega network also inputs large quantities of renewable energies from water power, wind power, biomass and photovoltaic sources into the grid.
The Institute for Climate Protection, Energy and Mobility e.V. (IKEM) is an independent institute and charitable organisation with sites in Berlin and Greifswald, and has been researching some of the most important questions of the energy and mobility transition since 2009. The focus of its research is on the reciprocal interactions between climate protection, law, economics and politics and the level of acceptance for energy and climate protection projects.
Deutsche WindGuard GmbH, based in Varel, Lower Saxony, is one of the leading independent service providers in the wind energy sector. The consortium has been active in the fields of acceptance testing and business management, location analysis, measurement, consulting and certification since 2000. Deutsche WindGuard sees its mission as independent, manufacturer-neutral consulting.
