Use cases

Industrial site Max Bögl

GERMANY
Lifetime 20 years
Export Use as a project template
An industrial site with an annual electricity consumption of 26 GWh and a peak load of 6.3 MW is aiming to increase its self-sufficiency rate and reduce its grid connection power by expanding pv, wind power and a battery. This is shown in four different scenarios.
  • 1. actual state
  • 2. S01 + PV
  • 3. S01 + PV + Wind
  • 4. S01 + PV + Wind + Battery

Electricity supply to community

GERMANY
Lifetime 20 years
Export Use as a project template
A community of 3,000 residents wants to determine how they can increase the self-sufficiency of their electricity supply. PV and wind as renewable sources are considered, and battery storage.
  • 1. DSO supply to community
    The current electricity supply of the community is analyzed as a reference case. The import electricity price is 0.16 €/kWh.
  • 2. DSO + PV supply to community
    The community investigates if investing in PV is a feasible option. The optimal capacity is determined.
  • 3. DSO + wind supply to community
    The community investigates if investing in wind is a feasible option. The optimal capacity is determined.
  • 4. DSO + PV + wind supply to community
    The community investigates the option of both PV and wind as renewable sources. The optimal capacities of each are determined.
  • 5. DSO + PV + wind + battery supply to community
    The goal is for the community to reach a 98 % minimum renewable share for their energy system. For this reason, a battery storage is included.

Heat supply to community

GERMANY
Lifetime 20 years
Export Use as a project template
A community of 3,000 residents wants to determine how they can increase the self-sufficiency and renewable share of their heat supply.
  • 1. Heat supply to community
    The current heat supply of the community is analyzed as a reference case. The import price for heat is 0.1 €/kWh.
  • 2. Biomass supply to community
    The full replacement of natural gas and boilers with biomass and biomass boilers is considered. The import price of biomass is 0.062 €/kWh.
  • 3. Heat supply + PV/heat pumps to community
    The community aims to have 70 % minimum of their heat supply from renewable sources. The optimal capacities for PV and air-source heat pumps are determined.
  • 4. Heat supply + PV/heat pumps + storage to community
    The community aims to have 70 % minimum of their heat supply from renewable sources. The optimal capacities for PV and air-source heat pumps are determined. The option for thermal storage is also included to see what effects, if any, this has on the system results.

Sector coupling for office building

GERMANY
Lifetime 20 years
Export Use as a project template
An office building aims to improve the sustainability, overall efficiency and flexibility of its energy system by introducing renewables and considering sector coupling for electricity and heat.
  • 1. Current energy suppy to building
    The energy supply of an office building is shown as a reference case.
  • 2. Rooftop PV and solar thermal
    The office building looks to invest in 100 kWp solar PV and 50 kW solar thermal on the rooftops.
  • 3. Heat pumps
    The required capacities to fully cover the heat supply with solar thermal + heat pumps is determined.

Hydrogen production for a technology park

GERMANY
Lifetime 20 years
Export Use as a project template
A technology park considers locally producing hydrogen from excess PV generation, either for using as a means of electricity storage or for external sales.
  • 1. Current energy suppy
    The current electricity supply of the technology park is evaluated, as a reference case. 150 kWp PV is already installed.
  • 2. Additional PV
    The technology park invests in an additional 150 kWp PV to see if this increases the renewable share of the energy system, and if it's financially beneficial.
  • 3. Additional PV + H2 for electricity storage (opt cap)
    The technology park invests in an additional 150 kWp PV, and the potential for H2 as electricity storage from excess PV production is considered. The electrolyzer and storage costs are in €/kgH2, and if the assets chosen to be installed in the system, the capacity is also in kg. Fuel cell costs are in €/kW (output power).
  • 4. Additional PV + H2 for sales (10 €/kgH2)
    The technology park invests in an additional 150 kWp PV, and the costs of supplying H2 for 10 €/kg is analysed. Note: the electrolyzer costs must be set in €/kgH2, and the output capacity will be in kgH2.
  • 5. Additional PV + H2 for sales (12 €/kgH2)
    The technology park invests in an additional 150 kWp PV, and the costs of supplying H2 for 12 €/kg is analysed. Note: the electrolyzer costs must be set in €/kgH2, and the output capacity will be in kgH2.
