Standardisation Process
EEBUS is the central process driver for generating the best solution with inputs from three areas: our working groups (WG’s), funded projects as well as standardisation and regulatory bodies. Process starting point are market ideas and requirements coming from our member companies or funded projects in which EEBUS interacts with other organisations. These market requirements are translated into use case specifications ready for standardisation.
The EEBUS specification experts team ensures consistency and interoperability among the various use cases and organises cross-industry ‘’Plugfests’’ for system verification of new use cases to be released. Our standardisation experts then transfer the use cases into the relevant standardisation bodies and committees. Being an open standard, released use cases are publicly available on our homepage to be download.
Release of the UC by:
- Review incl. risk analysis (e.g. FMEA)
- Plugfest
- Field testing of individual manufacturers
- Standardisation bodies
Translating market requirements into new standards
WORKING GROUPS
The working groups are an essential part of our EEBUS organisation: participating member companies actively shape the design of new use cases according to their market requirements. Experts from the companies meet with EEBUS specification engineers on a regular basis to jointly work out the use case specifications and enhance the underlying data model where required. Meeting agendas and minutes as well as the latest use case versions are available on a SharePoint where members can access.
The philosophy of EEBUS is that all energy relevant devices from cross sector domains need to be able to interact and the interaction with the low-voltage grid needs to be properly managed. This cross-domain useability is well reflected in our working group structure. The following groups are working on the standard-based integration of domains into a broader and holistic eco system:

Solutions
The holistic application approach with its increasing number of use cases has led us to the definition of compact solutions. In this way, use cases are clustered usefully to reduce complexity, that would otherwise arise. The following standard-based solutions are already available today:
Use Cases are available for:
Power Limitation:
Enables Distribution System Operators (DSO) to monitor power consumption on building or device level and to limit power consumption via temporary power limitations.
Tariff Management:
Enables DSO to optimise local grid load via dynamic grid fees or ESP to optimise cost-effective operation of energy devices based on electricity market prices. Customers benefit from cost optimised operation of own devices.
Preventive Capacity Allocation:
Enables DSO or ESP to adjust power curve of buildings or devices beforehand to avoid grid congestion or to participate in flexibility and balancing markets.
Increase of Self Consumption:
Enables customers to benefit from local PV production over the day and using stationary battery system or bi-directional EV-charging after sun set.
Additional Use Cases for Monitoring & Control:
Enables an increased flow of information for the EMS to optimise its operation and comfort functions for the customer.
All use cases may be used free of charge. A short high-level description of the EEBUS use cases, the phase model and the specification process can be found in the download area.
EEBUS
Use cases
EEBUS enables holistic application by its use case specifications employing the domain unspecific data model SPINE: irrespective of device type or stakeholder role, it is the generic data model allowing for a broad range of use cases. The use cases are clustered along the working groups in which they have been developed. Finally, a transport protocol is required for transmission of the EEBUS SPINE data: EEBUS members have deliberately chosen an IP approach and developed the Smart Home IP (SHIP) transport protocol to be best-in-class with respect to cyber security and energy networking inside buildings.
Spezifications are available for:
E-Mobility Use Case Collection
Grid Connection Point Use Case
Inverter Use Cases
HVAC Use Cases
The EEBUS specifications are openly available, free of charge and can be used without any license costs: you will find the following specifications in the current version in the download area. Please note that we can provide so-called snapshot versions only to our members.
EEBUS
technical backbone
Clean system architecture – EEBUS Use Cases all rely on the data model SPINE, which can be transmitted via a large variety of transport protocols.
EEBUS recommends widely applied IP communication technologies: Standard based security mechanism such as TLS 1.2, commonly used cipher suites, several elliptic curves together with the certificate update mechanism guarantee maximum security – now and in the future.

EEBUS De Jure Standards
Today’s accelerating energy transition demands eco-systems to reach a critical mass. These eco-systems consists of a complex compilation of multiple energy relevant and controllable devices from numerous buildings. For the applied communication interface a de facto standard is not sufficient to ensure the necessary investment security. EEBUS therefore focuses on creating a de jure standard that allows for a secure investment in the development of mass market suitable serial products. EEBUS contributes with the experience and results from joint development of standards in important standardisation bodies and plays a key role in shaping future standards. Further domains for standardisation are being consistently promoted.

„Standardisation is less about what is right and what is wrong but about balancing all interests and domains involved.“
EEBUS is active in the following important standardisation bodies:
EEBUS COOPERATIONS
EEBUS is partnering with leading alliances and consortiums in Europe and the US: the common goal is to push forward the international harmonisation of the energy landscape for interoperable solutions. The integration of EEBUS, therefore, stands for reduced development costs and investment security for manufacturers.
Our partners:
OpenADR
For a standardised interface solution from smart grid to grid connection point
ESMIG
For a standardised interface solution from smart grid to smart meter
CharIn
For a standardised interface solution from grid connection point to electrical vehicle supply equipment
Cross Industry Network –
more than just a technical standard
The cross-industry network plays a central role in the energy transition and thus within EEBUS. Through the constant exchange of individual information, a common understanding is developed, creating the basis for new use cases and business models. Solutions around capacity and tariff management involve multiple players and a wide variety of industry partners. An efficient solution can only come about if companies either define a solution bilaterally with the most important partners, which is usually very time-consuming, or follow an established standard that considers cross-industrial application, such as EEBUS. In this cross-industry network manufacturers can very easily enter the solution business.
„Since our founding in 2012, EEBUS members have come from a variety of industries: I am convinced that this cross-industry approach is the main reason for our success as the communication interface standard for the low-voltage grid – it is impossible to imagine sector coupling in the context of energy transition if the interests of all sectors involved are not well aligned! “
Industrial Research Projects
One of EEBUS’ main activities is its active contribution to research and development: the initiative participates in various national as well as international funded projects devoted to developing the energy landscape of the future. Requirements and results deriving from these projects are important sources of input for the development of the EEBUS standard and vice versa.
Unit-e
How electromobility can be optimally integrated into the power grid is being investigated by the research project "unIT-e² - Reallabor für verNETZte E-Mobilität" in four field tests across Germany. To approach the complex topic from all sides at the same time, 29 partners from the automotive and energy industries, IT and charging infrastructure as well as science are participating in the joint project. The focus is on the user-friendly, large-scale implementation of bidirectional charging concepts. The three-year project is funded by the Federal Ministry for Economic Affairs And Climate Action (BMWK). Holistic solutions are being developed in the project for the further ramp-up of electromobility.
Main Achievement:
Grid Integration of electromobility
Test locations/sites:
Urban areas of Munich and Düsseldorf as well as rural based field tests in Eastern Bavaria, Lower Saxony, and Northern Hesse.
Working groups:
E-Mobility, HVAC, Inverter, Grid
Our Partners:
Fit4echange
The project focus lies on the increase of grid stability with a simultaneous ramp-up of e-mobility. Within Fit4echange, sensor and visualisation tools, allowing for increasing transparency in the current and prospected grid status, are to be developed as well as processes to inform the grid operator about an imminence grid congestion in advance. This information is necessary for the grid operator to react upon, i.e. by setting power limitations at the respective grid connection points via EEBUS communication.
Main Achievement:
Digitalisation and controllability of the low-voltage grid

RESIGENT
In the near future, several market participants with correlating interests and control demands will reach the smart building and it’s devices. A grid operator could send a power limitation to reduce the total power consumption, while an aggregator sends a price incentive to increase the power consumption. In RESIGENT a coordinating entity that prioritise the signals from all market participants before reaching the building is to be developed. Furthermore failsafe and blackstart mechanisms are to be tested to power up devices and systems after a power or communication blackout.
Main Achievement:
Coordination of grid interaction
