Map 08.02 Predominant Heating Types

Map 08.02.1 - Supply Shares of Individual Energy Carriers

As the predominant heating types represented on this map demonstrate, the heating structures within the two city halves still differ greatly. In the west, particularly the areas outside of the inner City-Rail Circle Line, fuel oil has a long tradition of being the dominant fuel type for building heating.

In the inner city, district heating is generally the primary heating source. Natural gas is a dominating source only in parts of Kreuzberg, Neukölln and Wedding; however, as mentioned above (cf. 08.01.2 Gas Heating Supply Areas), its use has become wide-spread throughout Berlin.

In the eastern parts of the city, the dominating role of coal heating that could still be noted for large areas in 1994 has diminished almost completely. It has been replaced foremostly with natural gas and district heating. The dramatic increase in gas heating recorded since 1994 - almost 70 percent - is caused primarily by increased usage in the eastern boroughs. Thanks to the established supply networks, district heat has also been a primary source for heating in these areas, even before 1989. In the modern development projects of Marzahn and Hellersdorf, district heat in fact has a supply share of 100 percent.

In some outskirt areas such as Biesdorf, Mahlsdorf and Rahnsdorf, mixed supply types dominate, e.g., gas plus fuel oil. As with another frequently encountered mixed supply type - district heat plus fuel oil - this is largely a result of replacing coal as an energy source. In the western part, mixed supply with gas and oil is dominant in areas with contiguous block development, for instance Schöneberg, Tiergarten, Wedding, as well as Spandau and Reinickendorf.

With regard to future developments in the use of heating energy, it is the mixed supply areas of Berlin that are of particular interest - as are those where different supply structures are directly adjacent. Due to the spatial proximities in these areas, there are great opportunities to further develop the use of district heat and gas.

Map 08.02.2 - Fuel Use of Major Heating Plants and Heating Power Plants

Map 08.02.2 Fuel Use of Major Heating Plants and Heating Power Plants demonstrates that even in Berlin's power plants, fuel use varies greatly. The predominant energy sources used in the city's 35 certified plants are anthracite and lignite (about 40 percent each) as well as natural gas (20 percent). Fuel use ranges from 100 percent natural gas (e.g., the Charlottenburg and Mitte heating plants) to 90 percent lignite (e.g., Klingenberg heating power plant) (cf. also fig. 7).
