POTEnCIA (Policy Oriented Tool for Energy and Climate Change Impact Assessment) is a modelling tool that allows for a robust assessment of the impact of different policy futures on the EU energy system developed by the JRC.

It is designed to assess the impacts of alternative energy and climate policies on the energy sector, under different hypotheses about surrounding conditions within the energy markets. The model follows a hybrid partial equilibrium approach combining behavioural decisions with detailed techno-economic data, therefore allowing for an analysis of both technology-oriented policies and of those addressing behavioural change. Special mechanisms and features are implemented as to appropriately represent the transformation of today’s energy systems and capture the implications of the uptake of novel energy technologies and of changing market structures.

The output of the model consists of:

  • detailed energy balances and energy- and process- related CO2 emissions
  • energy system costs and prices
  • activity indicators
  • installed equipment capacities, characteristics and rate of use (both for the demand and the supply side)
  • dynamic technology improvements for the demand side

The model covers each EU Member State separately, while offering, in addition, the option of addressing the EU energy system as a whole. The typical projection period that can be analysed by POTEnCIA is up to year 2050 in annual steps.
