The FORECAST model is part of a larger energy systems model family operated by Fraunhofer ISI29 is designed as a tool that can be used to support strategic decision making. Its main objective is to support the scenario design and analysis for the long-term development of energy demand and greenhouse gas emissions for the industry, residential and tertiary sectors on EU MS level. FORECAST considers a broad range of mitigation options to reduce CO2 emissions (e.g. incremental energy efficiency improvements, fuel switch to RES, innovative process technologies, CCS), combined with a high level of technological detail (e.g. FORECAST Industry models more than 200 saving options for more than 70 industrial processes). It is based on a bottom-up modelling approach considering the dynamics of technologies and socio-economic drivers. Technology diffusion and stock turnover are explicitly considered to allow insights into transition pathways. The model further aims to integrate different energy efficiency and decarbonisation policy options. The model allows to address research questions related to energy demand including the analysis of scenarios for the future demand of individual energy carriers like electricity or natural gas, calculating energy saving potentials and the impact on greenhouse gas (GHG) emissions as well as abatement cost curves, ex-ante policy impact assessments and the investigation of long-term sustainable energy transition scenarios (www.forecast- model.eu, Jakob et al. 2013, Fleiter et al. 2018, Herbst et al. 2017).
Recent projects carried out with the FORECAST model are, amongst others:
- Industrial Innovation: Pathways to deep decarbonisation of industry [DG CLIMATE ACTION] (Fleiter et al. 2019)
- Set-NAV Navigating the Roadmap for Clean, Secure and Efficient Energy Innovation [H2020] (Herbst et al. 2018, Hartner et al. 2019)
- REFLEX – Analysis of the European energy system under the aspects of flexibility and technological progress [H2020] (www.reflex-project.eu)
- Service contract on market testing for low-carbon innovation support to energy intensive industry and to power generation [DG CLIMATE ACTION] (Eichhammer et al. 2018)
Within the project the FORECAST model will be used in WP3, WP5, WP6 and WP7 to calculate the decarbonisation pathways for the tertiary and the industrial sector, as well as for electric appliances considering new trends in prosumaging, digitalization and circular economy.
Invert/EE-Lab is a dynamic bottom-up techno-socio-economic discrete choice simulation tool that evaluates the effects of different policy packages on the total energy demand, energy carrier mix, CO2 reductions and costs for space heating, cooling, hot water preparation and lighting in buildings. The model is based on highly disaggregated data of the building stock. Each building segment is described by geometry data, U-values of building components, construction period, age and type of installed heating and hot water system etc.
The core of the tool is a nested logit approach, which optimizes objectives of agents under imperfect information conditions and by that represents the decisions maker concerning building related decisions.
In over 40 projects and studies for more than 30 countries, the model has been extended and applied to different regions within Europe, see e.g. (Kranzl et al., 2012), (Kranzl et al., 2013), (Biermayr et al., 2007), (Haas et al., 2009), (Kranzl et al., 2006), (Kranzl et al., 2007), (Nast et al., 2006), (Müller, 2010), (Müller, 2015).
Relevant recent projects carried out with the INVERT model are, amongst others:
- SET-Nav (Navigating the Roadmap for Clean, Secure and Efficient Energy Innovation), completed 2019, [H2020]
- Mapping and analysis of the current and future (2020 – 2030) heating/cooling fuel deployment (fossil/renewables), completed 2015, [Service contract for the European Commision (DG ENER)]
- progRESsHEAT (Fostering the use of renewable energy for heating and cooling), completed 2017, [H2020]
- ENTRANZE (Policies to ENforce the TRAnsition to Nearly Zero Energy Buildings in the EU-27), completed 2014, [IEE]
Within the project, the Invert/EE-Lab model will be used in WP3 and WP5 to analyse decarbonisation pathways for the building sector, considering new trends in prosumaging.
The PRIMES (Price-Induced Market Equilibrium System) is a large-scale applied energy system model providing detailed projections of energy demand, supply, prices and investment to the future, covering the entire energy system including emissions. The distinctive feature of PRIMES is the combination of behavioural modelling (following a micro-economic foundation) with engineering aspects, covering all energy sectors and markets. The model has a detailed representation of policy instruments related to energy markets and climate, including market drivers, standards, and targets by sector or overall (over the entire system). It handles multiple policy objectives, such as GHG emission reductions, energy efficiency and renewable energy targets, and also provides a pan-European simulation of internal markets for electricity and gas.
PRIMES offers the possibility of handling market distortions, barriers to rational decisions, behaviours,
as well as and market coordination issues and includes a complete accounting of costs (CAPEX and OPEX) and investment expenditure on infrastructure needs. PRIMES is designed to analyse complex interactions within the energy system in a multiple agent – multiple markets framework. Decisions by agents are formulated based on a microeconomic foundation (utility maximization, cost minimization and market equilibrium) embedding engineering constraints, behavioural elements and an explicit representation of technologies and vintages and optionally perfect or imperfect foresight for the modelling of investments in all sectors. PRIMES is well-placed to simulate medium and long- term transformations of the energy system (rather than short-term ones) and includes non-linear formulation of potentials by type (resources, sites, acceptability etc.) and technology learning.
The PRIMES model runs in 5-year time steps from 2020 to 2070; the years 1990 to 2015 are calibrated to statistics. Yearly resolution can be made available upon request. The PRIMES model covers all 28 EU Member States individually with country specific models; the model is further available for 10 other European countries.
Specifically, the following parts of the model30 will be improved in the course of the planned project notably in WP3, WP5 and WP7:
- PRIMES-TREMOVE transport model: recently enhanced to include linkage to synthetic fuels and hydrogen and to detailed spatial projections of transport activity and route assignment by the forthcoming TRIMODE model31 (used notably in WP7); recent publications include (Siskos et al. 201932, Siskos et al. 201833)
- PRIMES BuiMo residential and services model: new model with high resolution representation of the housing and office building stock, embedded in an economic-engineering model of multi-agent choice of building renovation, heating system and equipment/appliances by energy use (used in WP5); recent publications include (Fotiou et al. 201934)
- PRIMES Electricity and Heat/Steam supply and market model: fully new model version which includes the hourly unit commitment model – with a pan-European market simulation over the grid constraints and detailed technical operation restrictions – the long-term power system expansion model, the costing and pricing electricity and grid model, the integration of heat supply and industrial steam supply with synchronised hourly operation. This part of the PRIMES model allows analysing impacts of Prosumagers on the supply sector in WP5.
Recent projects carried out with the PRIMES model are, amongst others:
- EU Reference scenario 2016, Energy, Transport and GHG Emission Trends to 2050 (last version published in 2016; presently ongoing)
- INNOPATHS: Innovation Pathways, Strategies and Policies for the Low-Carbon Transition in Europe, ongoing, [H2020]
- ASSET: Sectoral integration – long-term perspective in the EU Energy System, ongoing: several studies completed, [DG ENERGY]

A new modelling feature that allows households to endogenously decide upon the optimal schooling-education years is introduced. Skills representation is extended to five skill levels based on the GTAP classification and linked to decisions of households regarding education, which then influenced the labour productivity of skills.
