C/sells Autonomy Lab Leimen as blueprint for the amendment of §14a EnWG and §9 EEG

The C/sells demo cell Leimen demonstrates for the first time a practical solution for the implementation of current draft laws and amendments with regard to controllability at the digital grid connection point. With the design and concept implemented in Leimen, the grid operator is on the one hand empowered to monitor the current power at the grid connection point of a building and on the other hand – in case of a grid-critical situation – to temporarily limit this power. Starting from the grid control center, a power limitation, which can apply to both the supply and the demand, is transmitted to the building via a safe channel through the smart meter gateway. The signal is then transmitted via the FNN control box to the local energy management system. Latter controls again all connected devices in the building according to this maximum available power, e.g. by reducing the charging current of the wallbox. The implementation is based on the EEBUS standard as well as the new VDE application rule 2829-6. The C/sells partners Stadtwerke Schwäbisch Hall, VIVAVIS AG, Schleupen AG, Fraunhofer IEE and KEO GmbH as well as prosumer Andreas Kießling (energy design) were part of the technical success.

PEEEKS integrates EEBUS, for plug & play connectivity of smart energy devices inside buildings

The specialist for home energy management Peeeks integrates EEBUS, for plug&play ready connection and connectivity of smart energy devices in the building. Intelligent control of energy at home: Peeeks networks energy consumers and producers in the household and thus enables optimization of own consumption, intelligent charging management and integration into flexibility trading. With EEBUS, Peeeks’ Energy Management System (EMS) receives the standardized interface for communication with all energy-relevant device domains within the building and the grid. To begin with, Peeeks offers its customers full support of all EEBUS E-Mobility functionalities. Peeeks cooperates with KEO GmbH for the integration of EEBUS into their energy management solutions


KEO sees green!

Can small businesses also make their contribution to achieving climate targets? As a young software company with offices in two locations, we believe: Yes!

In order to reduce our consumption of resources to a minimum and at the same time strengthen our economic efficiency and authenticity, we are one of 13 motivated participants of the Ökoprofit Program NRW since autumn 2019.

In collaboration with FC Köln, Brauerei Heller, Stadtwerke Hürth and other committed companies and associations, we are working in regular workshops and individual consultation to develop, step by step, measures for the long-term reduction of our costs while simultaneously increasing our eco-efficiency.

The overarching objective is the sustainable economic and ecological strengthening of our company. Central topics are the reduction of water and energy consumption as well as waste reduction and the increase of material efficiency.

We will minimize our ecological footprint, resulting from electricity, heat and mobility requirements, to the maximum extent possible!

Furthermore, we want to focus on the topic of sustainable software: The creation, operation and benefit of the software should be sustainable.

More specifically, we have set ourselves a target of 2020 (cf. 2018):

  • Reduce the amount of waste by 25%.
  • Reduction of CO2 emissions by 50%.
  • Publication of our guidelines on resource use and sustainable software

Our goals for 2022 (cf. 2018) are:

  • CO2 neutrality
  • Reduction of the amount of waste by 50%.
  • Convince at least two other companies to participate in Ökoprofit or comparable certification

It becomes obvious: KEO not only sees red (during the next match of our famous local football team FC Köln) but also green.

The 13 participants in this year’s round are:


PPC implements e-mobility solution with EEBUS

In order to control charging processes of electric cars from the grid operator’s perspective, Power Plus Communications AG (PPC) has developed an interoperable solution together with KEO. For this purpose, the partners have extended the functional scope of the CLS Gateway from PPC to include EEBUS. The upgrade enables communication with a charging station via the CLS Gateway using the EEBUS protocol. This solution can be easily transferred to the Smart Meter Gateway architecture in other projects. PPC and KEO thus already enable the interoperable control of charging points today.
