What can I choose in the calculator?

The calculator lets you choose the share of total heat demand (in Industry) 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.

DEFINITION / CONSTRAINTS

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.

In 2010, 25 % of the heat supply to the industry was provided by direct electric heating.[1]

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.

ASSUMPTIONS – What are the assumptions considered in the calculator?

Next tables contain the assumptions that have been introduced in the Direct electric heating (Industry) model of the calculator.

Efficiency [%]
2011-2050
100
Emissions
2011-2050
CO2-eq. emissions [kgCO2-eq./kWhth] They depend on the electricity production.
Deposited waste [UBP/kWhth]
Cost
2011-2050
Specific investment [CHF2010/kWe] 284
