Energy production in the FrankfurtRheinMain region


Overview

Energy production in the area of the Regional Authority is not sufficient to cover consumption. Electricity, as a transportable energy form, must be imported from outside the region. In the region itself, energy is produced from renewable energies, waste incineration, fossil (heating) power plants, and fossil domestic fuel use.


Data source

In the following you will find detailed information on electricity and heat production in the region. The source is the municipal energy profile for the Regional Authority FrankfurtRheinMain. You can find the profile for the Regional Authority as well as the data for the individual member municipalities and districts under the municipal energy profiles and in the climate-energy atlas.


More than half of the consumed electricity in 2015 had to be imported; the majority of electricity consumption is based on fossil fuels

In 2015, about 58% of the electricity needed to cover electricity consumption in the Authority area had to be imported from outside the region. This corresponds to about 9.5 TWh/a. The largest remaining share of local electricity production in electricity consumption was covered by fossil power plants (about 34% or ≈5.5 TWh/a). Local electricity production from renewable energies had a share in electricity consumption of about 5% (≈0.8 TWh/a).

 

The share of imported electricity is calculated as the difference between local electricity consumption and local electricity production. Assuming the German electricity mix for the imported electricity (taking into account only fossil and renewable energies), the entire share of fossil electricity production in electricity consumption in the region was about 64%. The share of renewable energies was around 22%. The share of nuclear energy in the German electricity share has not been considered.

Most municipalities import the majority of electricity


2_Energieerzeugung_Strom_Import KommunenThe illustration shows how import-dependent many member municipalities are in order to cover their electricity consumption. Only in a few cases do the municipalities have local production capacities that cover the majority of overall electricity consumption. This includes the municipalities Frankfurt, Rüsselsheim, Offenbach, and Großkrotzenburg, in which fossil power plants are situated; as well as the municipalities Schöneck, Karben, Friedberg, Weilrod, Nidderau, and Florstadt, in which wind energy covers parts of their own electricity consumption. The municipality Flörsheim am Main is able to cover its own electricity consumption with the bio-mass power plant and the landfill and bio-gas plant Wicker.

Electricity production from renewable energies: Bio-mass most important energy source

In 2015, local electricity production from renewable energies covered about 5% of the electricity consumption in the region (≈840 GWh). The largest share of local electricity production from renewable energies was based on biomass with 40% (≈336 GWh/a). Following, photovoltaics had a share of 29% (≈244 GWh/a) and hydroelectric power roughly 12% (≈103 GWh/a). Wind energy generated about 10% (≈86 GWh/a) of the local electricity. Gas obtained from sewage and landfills had the lowest share of local electricity production from renewable energies with around 9% (≈71 GWh/a).

Renewable energies: Installed capacity (2001 to 2015)

In the period from 2001 to 2015, renewable energies experienced a solid development in the region. Over the last five years considered (2010 to 2015), installed capacity of renewable energies in the area of the Authority had increased by about 88% – from roughly 224 MWel. to about 422 MWel. This increase was especially driven by a growing number of photovoltaic plants, whose installed capacity increased by more than 130% (from about 116 MWel. to approximately 270 MWel.) between 2010 and 2015. Over the same period, wind energy also experienced an increase in installed capacity by about 116% (from nearly 25 MWel. to about 54 MWel.). The installed capacity of bio-mass increased by 17% between 2010 and 2015 (from about 52 MWel. to roughly 61 MWel.).

 

In total, installed capacity of photovoltaic plants in 2015 was about five times as high as the installed capacity of wind energy and made up about 64% of the total installed capacity of all renewable energies in the region.

Renewable energies: Electricity production (2001 to 2015)

As has been the case with installed capacity, electricity production from renewable energies also increased between 2001 and 2015. In comparison to 2010, electricity production from renewable sources increased by around 586 GWh/a (or about 43%) to 840 GWh in 2015. Especially photovoltaic electricity production increased significantly over this time span – by about 125% (from 108 GWh to 243 GWh). Electricity production from wind roughly doubled over the same period (from 42 GWh to 85 GWh).

 

However, as depicted above, most electricity is finally generated with biomass. 40% of the total local renewable electricity production in 2015 was based on this energy source. In the same year, electricity production from photovoltaic plants was about 29%.

One should bear in mind that electricity production with renewable energies is subject to weather-related fluctuations. These can influence annual comparisons.

Renewable electricity production in the municipalities

6_Energieerzeugung_Strom_Erneuerbare_KommunenWhile photovoltaic plants produce electricity in all municipalities within the area of the Authority (with Frankfurt at the top), the locations where wind energy is produced are concentrated in the east and north-east of the Regional Authority's area, particularly in the municipalities Schöneck and Weilrod. Wind energy is also produced in Karben, Friedberg, Nidderau and Florstadt.

 

Hydroelectric power is mainly produced with dams along the river Main. Dams are located in Maintal, Offenbach, Frankfurt and Hattersheim. 

 

The main contribution to electricity production from bio-mass, bio-gas, and landfill gas come from the bio-mass power plants Wicker and Fechenheim as well as the bio gas and landfill gas plant also located in Wicker.

Heat consumption is almost completely covered by non-renewable energy sources

Heat consumption in the region was about 33 TWh in 2015. For the local production of heat (without heat generated from electricity), non-renewable technologies clearly dominated – their share lay around 98% (≈32.2 TWh/a). Out of those, about 78% of the consumption was supplied by fossil fuels as domestic fuel in buildings (≈25,5 TWh/a), about 17% by combined heat and power plants as well as combustion plants (≈5.4 TWh/a), and roughly 4% from waste incineration (≈1.2 TWh/a).

 

Only about 2% (≈0.7 TWh/a) of the heat consumed, was generated with renewable energies.

Bio-mass plays the main role in heat production from renewable energies


Only about 2% of the heat consumption in 2015 was produced by renewable energies within the region. This corresponds to 735 GWh/a. Of this amount, about 59% (≈431 GWh/a) was produced from bio-mass and bio-gas (including wood and residuals for private households, such as pellets). Heat pumps and flat geothermal plants (up to 150 m deep, for instance with ground heat collectors, geothermal energy probes, or groundwater wells) produced about 20% (≈146 GWh/a) of the local renewable heat. Solar thermal energy produced around 8% (≈60 GWh/a). Sewage- and landfill gas generated nearly 13% (≈92 GWh/a) of the local renewable heat.

 

Bio-mass and bio-gas thus play the most important role for electricity- and heat production from renewable energies within the region.

Heat production from renewable energies (2001 to 2015)


Similar to electricity production from renewable energies, heat production from renewable energies continuously increased over the period from 2001 to 2015. Over the last five years (from 2010 to 2015) local heat production from renewable energies increased by about 16% (from 634 GWh/a to 735 GWh/a), of which the increases in production were the strongest for solar thermal with 20% (from 50 GWh/a to 60 GWh/a) and bio-mass plus bio-gas with about 18% (from 366 GWh/a to 431 GWh/a). The share of heat pumps and flat geothermal plants increased by nearly 17% (from 124 GWh/a to 145 GWh/a) from 2001 to 2015.

 

In 2015, roughly 59% of the total renewable heat production in the region was based on bio-mass and bio-gas. The entire regional heat production with renewable energies (735 GWh in 2015) is only about 14% lower than the entire electricity production from renewable energies (840 GWh in 2015) in the region.
