THE SEMIAH MOTIVATION
Residential electricity consumption
breakdown in the EU-27
Demand response potentials

The operation of wet appliances can be
shifted in time without affecting user comfort.
Up to 40% of household
electricity
Postponing
the operation of a heat pump for
a small amount of time (up to 30 min.) does
consumption cannotbe

affect
the comfort but creates a

considerable amount of flexibility.

The operation of a micro CHP plant can be
shifted in the same manner as the heat pump
(shifting operation in time; operate at partial
output e.g., 70%; or full power).
An aggregated demand response
Hot water boilers
represents an energy buffer,
need many small contributions

SUMMARY & OUTLOOK

There is a need to adapt the electricity consumption side to cope with the fluctuations in
generation from renewable energy sources (wind and PV).

ICT can be utilized as a cost-effective way to exploit flexibilities in consumption through
Demand Response programs:

The European research FP7 project SEMIAH investigates scalable demand response in
residential households;

The ForskEL project VPP4SGR looks at the integration of building automation using a
combination of direct and in-direct electricity load control;

Key challenges in demand response research: user involvement, scalability, quality of
a demand response, new business models – trading flexibility.
