Scalable Energy Management Infrastructure for Aggregation of Households

The research project SEMIAH, conducted by Develco Products together with 11 other European members of the consortium, is developing a novel Information and Communication Technology (ICT) infrastructure for aggregation of households. Through the implementation of Demand Response in private households, this infrastructure enables scheduling of high energy-consuming domestic loads’ operation to off-peak demand periods for reducing the peak demand on networks.

By being deeply involved in the development of the wireless platform, Develco Products promotes an environment for the deployment and innovation of smart grid services in households for load management with this project.

Benefits of SEMIAH

The SEMIAH concept enables aggregation of all the households connected to the system and acts through direct load control to shift or curtail electrical loads considering user’s flexibilities and utility demand limits. In this sense, SEMIAH provides an innovative solution to cutting down the energy consumption of household appliances without impeding their functionality.


The solution i.a. consists of Develco Products’ motion and temperature sensors, smart plugs and smart relays controlled via home area network through the Gateway. In addition, Develco Products has developed a ZigBee sensor that can be attached to boilers in order to collect temperature data. With these intelligent devices, SEMIAH is able to make the grid smarter by using load shifting mechanisms to relieve grid constraint during peak hours.


The deployment of SEMIAH in 200,000 households would allow the shifting of 90 GWh/year of electrical consumption from fossil fuels to RES, thereby reducing the gap between RES produced and consumed. Furthermore, SEMIAH is expected to reduce peak loads by 120 GWh/year.


SEMIAH contributes to the benefit of residential customers, energy utilities, and the society in general through lowering electricity bills, and higher stability of the electricity grid. In addition, SEMIAH enables savings in CO2 emissions and fuel costs, as well as reducing investments in electricity network expansions and electricity peak generation plants.


Unique Demand Response project

The SEMIAH project differentiates from other demand response studies by means of the aggregation of private households and by addressing a large number prosumers from three angles:

1.      Technical

2.      Business

3.      Security


On the technical side, the ICT infrastructure must be scalable and low-cost. Furthermore, new business models are needed to provide incentives to prosumers. Lastly, security and privacy aspects must be properly addressed to circumvent any concerns prosumers may have when considering to sign up with a residential demand response programme.


Status of SEMIAH

SEMIAH is a 3-year project that started in March 2014 and has a funding of more than 28 million DKK. At this point, the ICT infrastructure has been specified and development is ongoing. Moreover, the pilots and the recruitment of residential households in Norway and Switzerland are running.


With the SEMIAH technology, electricity utilisation is optimized without causing the prosumers any discomfort. This premise is supported by the pilots.
