European Directives on Renewables
Renewable Energy Directive 2009/28/EC is a European Union directive which
mandates levels of renewable energy use within the European Union.
The key objectives of the strategy are to reduce carbon dioxide emissions by
20%, to increase the share of renewable energy to 20%, and to achieve
energy savings of 20% or more

Modeling Framework
LEAP: Long-range Energy Alternatives Planning
≡ Energy and environmental simulation model: can reflect current situation
and develop forecasts under given assumptions
≡ Developed by Stockholm Environmental Institute (SEI) in the 1980s
≡ Consists of Modules: Demand, Transformation, Environment and
Evaluation
= In this work, the new capability of the LEAP software tool has been used to
calculate the optimal expansion and dispatch of power plants for German electric
system.
= A least cost system can optionally be calculated subject to a number of user
specified constraints including maximum annual levels of emissions for any given
pollutant (CO2, Sox, Nox, PM10, etc.) and minimum or maximum capacities for
certain plant types.
= We use LEAP’s model scenario capabilities to calculate explore different optimal
solutions under different sets of input assumptions.
= LEAP includes the capability to automatically calculate least cost capacity
expansion and dispatch of supply-side Transformation modules.

Modeling Framework
■ The objective function is to minimize the total discounted costs for each year and
for each technology
σyσtTotalDiscountedCostsy,t
■ Fuel production constraints:
Productiony,ts,f ≥ Demandy,ts,f + Consumptiony,ts,f
■ Capacity constraints:
Activityy,l,t ≤ TotalInstalledCapacityy,t ∗ CapacityFactory,t
■ Activity constraints:
σl(Activityy,l,t ∗ YearSplity,l) ≤ TotAnnCapy,t ∗ AvailFactory,t ∗ CapFactory,t
■ The calculations are based on linear programming. OSeMOSYS aims to calculate
the least-cost system

Concluding Remarks
Phase-out of nuclear power plants is feasible
DSM leads to minimised social costs
In Germany, there are already many existing Acts and Federal Governmental plan
towards heavy renewable energy implementation in the electricity mix and they are in
line with the European Union directives which is evident from the results.
The model result gives an indication towards renewable for long –term benefits.
Power-to-heat is theoretically not necessary
The results of the study suggest that implementation of renewable program at large
scale is possible technically as well as economically for Germany. The variation of
different renewable resources depends on the geographical situation.
