What can I choose in the calculator?

The calculator lets you choose the share of total decentralised heat demand covered by Direct Electric Heating in Switzerland in the selected year (2035 or 2050).

IMPACT – What are the impacts of Direct Electric Heating?

In Switzerland, increasing the share of Direct Electric Heating will have the following impacts:

Energy system

image Increase primary energy demand.

image Increase total electricity consumption.

image May increase total fossil fuel consumption if gas fired power plants are added to the grid.

image May decrease the share of renewable energy sources in the energy mix.

image Likely to raise pressure on the grid by increasing peak electricity demand.

Environment & Climate

image Likely to increase global CO2 emissions.

image Avoid emissions of combustion pollutants at the place of use (built area), but not necessarily where the electricity is generated.

Society & Economy

image Unclear impact on the cost of the energy transition: low cost of heating systems may be outweighed by need for additional grid and power plant capacity.

imageMay worsen balance of payments by increasing fossil imports.

GLOBAL MARKET – What is the global market for Direct Electric Heating?

In 2010, 12% of the heat supply to residential and service sector buildings was provided by direct electric heating.[1]


DEFINITION - What is Direct Electric Heating?

Direct electric heating is the use of resistive elements that convert electricity into heat. This can be in radiators or in under-floor heating.

The use of this technology has been actively incentivised by the Swiss Authorities after the oil crises of 1973 and 1979 in order to increase energy security. The situation is now reversed as policy makers make efforts to try and ban this technology.

CONSTRAINTS - What are the key barriers facing Decentralised Cogeneration deployment?

• The primary constraint on the deployment of direct electric heating is a matter of efficiency of energy use, as with the same amount of energy input it is possible to provide more heat with a heat pump or other energy sources. It is quite likely that direct electric heating will be banned in many European markets in the mid-term.

ASSUMPTIONS – What are the assumptions considered in the calculator?

Next tables contain the assumptions that have been introduced in the Centralized direct electric heating model of the calculator.

Efficiency [%]
CO2-eq. emissions [kgCO2-eq./kWhth] They depend on the electricity production.
Deposited waste [UBP/kWhth]
Specific investment [CHF2010/kWe] 240
