Towards a common language for demand-side flexibility


What’s happening in the smart energy world in terms of interoperability?

Companies have created impressive technologies for home energy management, but which are not yet connected in a way that can empower consumers and maximize savings. If products and systems can’t talk to one another, the benefits they promise cannot be realized and consumers are left confused and frustrated. Therefore, interoperability is critical to driving consumer adoption of energy management solutions going forward.


Moreover, competing standards and device compatibility issues impede a singular view of data, Consumers cannot see the benefits of these technologies if they don’t see the immediate impact they have on energy costs or how external weather conditions can impact the energy required to heat or cool a home. This is why all the stakeholders in the smart energy ecosystem must work together to empower smart consumers for the market to flourish. 


What’s being done about it?

The European Commission (DG-CNECT) has issued a study concerning the interoperability for demand side flexibility (DSF). A consortium consisting of DNV GL, TNO and ESMIG are identifying gaps in standardization, based on which they will recommend on alignments needed to achieve DSF interoperability and demonstrate an integrated infrastructure. 

The implementation of demand side flexibility not only requires energy market players, such as grid operators (DSO’s) and energy service companies (ESCO’s) including their technical infrastructures to cooperate, but also the complete chain of devices from the smart meter via home energy management system until smart appliances need to be coupled. Interoperability is key especially where the DSO infrastructure provides information that is needed by demand side flexibility applications. 

We can show it works!

We are the first to show a seamless integration flow of information from one product to the other, across industries. We do this by integrating standards from the telecom industries (from ETSI / oneM2M) with standards from the energy utility industries and home appliances industries (from CEN/CENELEC). We have partnered with EEBUS and Energy@Home and worked with our member companies to show the applications of demand-side flexibility in practice and in an open and standards-based infrastructure. The objective is to have all DSF solutions technically and economically feasible and based on European or international communications standards.

The demonstration includes two main functions: 

1  collection of meter data through different interfaces corresponding to the two types of data to be collected: data for billing and real-time data for energy management

2  home energy management through an integrated infrastructure that can be used by multiple market parties


Companies involved:

B/S/H: Smart appliance

Chameleon: Consumer feedback device

Geo: Consumer feedback device

Kamstrup: Head-end system, smart meters

Sierra Wireless: IoT platform for energy management

Telit: IoT platform for meter data collection

Vaillant: Heat pump controller

Vodafone: Mobile network

Watt-IS: Consumer data analysis

Whirlpool: Smart appliance

ZIV:  charging station


So what’s the plan?

1.    We’re organizing demonstrations with solutions for DSF interoperability based on use cases selected, short-listed standards and alignments.

2.    We are finalizing the study

The study will identify gaps in standards, will identify necessary alignments and will issue recommendations on implementing these alignments.

3.    We are reaching out to utilities and regulators to implement it

We will disseminate this study to utilities and regulators across Europe and make a case for implementing our solutions for achieving interoperability of demand-side flexibility.
