-How did we implement DSM? Results etc. 
+Demand-side management (DSM) potentials are calculated in function :func:`dsm_cts_ind_processing<egon.data.datasets.DSM_cts_ind.dsm_cts_ind_processing>`. 
+Potentials relevant for the high and extra-high voltage grid are identified in the function :func:`dsm_cts_ind<egon.data.datasets.DSM_cts_ind.dsm_cts_ind>`, 
+potentials within the medium- and low-voltage grids are determined within the function :func:`dsm_cts_ind_individual<egon.data.datasets.DSM_cts_ind.dsm_cts_ind_individual>` 
+in a higher spatial resolution. All this is part of the dataset :py:class:`DsmPotential <egon.data.datasets.DsmPotential>`. 
+The implementation is documented in detail within the following student work (in German): [EsterlDentzien]_.
+
+Loads eligible to be shifted are assumed within industrial loads and loads from Commercial, Trade and Service (CTS). 
+Therefore, load time series from these sectors are used as input data (see section ref:`elec_demand-ref`).
+Shiftable shares of loads mainly derive from heating and cooling processes and selected energy-intensive 
+industrial processes (cement production, wood pulp, paper production, recycling paper). Technical and sociotechnical 
+constraints are considered using the parametrization elaborated in [Heitkoetter]_. An overview over the 
+resulting potentials for scenario ``eGon2035`` can be seen in figure :ref:`dsm_potential`. The table below summarizes the 
+aggregated potential for Germany per scenario. As the annual conventional electrical loads are assumed to be lower in the 
+scenario ``eGon100RE``, also the DSM potential decreases compared to the scenario ``eGon2035``.

+DSM is modelled following the approach of [Kleinhans]_. DSM components are created wherever 
+respective loads are seen. Minimum and maximum shiftable power per time step depict time-dependent 
+charging and discharging power of a storage-equivalent buffers. Time-dependent capacities 
+of those buffers account for the time frame of management bounding the period within which 
+the shifting can be conducted. Figure :ref:`dsm_shifted_p-example` shows the resulting potential at one exemplary bus.

+The target values for scenario *eGon2035* are taken from the German grid development plan from 2021 [NEP2021]_,
+whereas the distribution on NUTS3-levels corresponds to the data from the research project *DemandRegio* [demandregio]_.

+
+A further spatial and temporal distribution of the electricity demand is needed to fullfil all requirements of the 
+subsequent grid optimization. Therefore different, sector-specific distributions methods were developed and applied. 
+
+Residential electricity demand
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The annual electricity demands of households on NUTS3-level from *DemandRegio* are scaled to meet the national target 
+values for the respective scenario in dataset :py:class:`DemandRegio <egon.data.datasets.demandregio.DemandRegio>`.

+Commercial electricity demand
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The distribution of electricity demand from the commercial, trade and service (CTS) sector is also based on data from 
+*DemandRegio*, which provides annual electricity demands on NUTS3-level for Germany. In  dataset 
+:py:class:`CtsElectricityDemand <egon.data.datasets.electricity_demand.CtsElectricityDemand>` the annual electricity
+demands are further distributed to census cells (100x100m cells from [Census]_) based on the distribution of heat demands, 
+which is taken from the Pan-European Thermal Altlas version 5.0.1 [Peta]_. For further information refer to section 
+ref:`heat_demand`.
+The applied methods for a futher spatial and temporal distribution to buildings is described in [Buettner2022]_ and 
+performed in dataset :py:class:`CtsDemandBuildings <egon.data.datasets.electricity_demand_timeseries.CtsDemandBuildings>`
+
+Industrial electricity demand
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To distribute the annual industrial electricity demand OSM landuse data as well as information on industrial sites are 
+taken into account. 
+In a first step (:py:class:`CtsElectricityDemand <egon.data.datasets.electricity_demand.CtsElectricityDemand>`)
+different sources providing information about specific sites and further information on the  industry sector in which 
+the respective industrial site operates are combined. Here, the three data sources [Hotmaps]_, [sEEnergies]_ and 
+[Schmidt2018]_ are aligned and joined.  
+Based on the resulting list of industrial sites in Germany and information on industrial landuse areas from OSM [OSM]_
+which where extracted and processed in :py:class:`OsmLanduse <egon.data.datasets.loadarea.OsmLanduse>` the annual demands
+were distributed.
+The spatial and temporal distribution is performed in 
+:py:class:`IndustrialDemandCurves <egon.data.datasets.industry.IndustrialDemandCurves>`. 
+For the spatial distribution of annual electricity demands from *DemandRegio* [demandregio]_ which are available on 
+NUTS3-level are in a first step evenly split 50/50 between industrial sites and OSM-polygons tagged as industrial areas.
+Per NUTS-3 area the respective shares are then distributed linearily based on the area of the corresponding landuse polygons 
+and evenly to the identified industrial sites.
+In a next step the temporal disaggregation of the annual demands is carried out taking information about the industrial
+sectors and sector-specific standard load profiles from [demandregio]_ into account.
+Based on the resulting time series and their peak loads the corresponding grid level and grid connections point is 
+identified. 
+
+Electricity demand in neighbouring countries
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The neighbouring countries considered in the model are represented in a lower spatial resolution of one or two buses per
+country. The national demand timeseries in an hourly resolution of the respective countries is taken from the Ten-Year 
+Network Development Plan, Version 2020 [TYNDP]_. In case no data for the target year is available the data is is
+interpolated linearly.

+The following steps are conducted:

+#. The sites and capacities of exisitng PV parks are imported using MaStR data (see :ref:`mastr-ref`).
+
+#. Potential areas for PV ground mounted are assumed to be areas next to highways and railways as well as on agricultural land with a low degree of utilisation, as it can be seen in figure :ref:`pv_ground_mounted-example`. Those areas (provided through the data bundle, see :ref:`data-bundle-ref`) are imported while merging or disgarding small areas.
+
+#. The locations of existing parks and the potential areas are intersected with each other while considering a buffer around the locations of existing parks to find out where there already are parks at or close to potential areas. This results in a selection of potential areas.
+
+#. The capacities of the existing parks are considered and compared to the target values for the specific scenario per federal state (see :ref:`concept-and-scenarios-ref`). The required expansion capacity is derived.
+
+#. If expansion of PV ground mounted capacity is required, capacities are calculated depending on the area size of the formerly selected potential areas. The resulting parks are therefore located on the selected potential areas.
+
+#. The resulting capacities are compared to the target values for the specific scenario per federal state. If the target value is exceeded, a linear downscaling is conducted. If the target value is not reached yet, the remaining capacity is distributed linearly among the rest of the potential areas within the state.
