Summary of JRC Science for Policy Report: The POTEnCIA Central Scenario

Core Content

This report outlines the evolution of the EU energy system up to 2050 under the Central scenario, which assumes no new policies or measures are introduced after the end of 2017. It uses the POTEnCIA model, a comprehensive energy system model developed by the European Commission's Joint Research Centre (JRC), to simulate the energy demand and supply trends across all EU Member States.

Main Findings

• Energy Intensity and CO₂ Emissions:
  The EU's gross inland energy consumption is expected to decrease by 13% between 2015 and 2050, despite a 68% increase in GDP. This indicates a significant decoupling of energy use from economic activity.
  CO₂ emissions are projected to fall by 24% in 2020, 30% in 2030, and 53% in 2050 compared to 1990 levels, but the 40% reduction target for 2030 will not be met under the Central scenario.

• Power Generation:
  By 2050, 83% of electricity generation in the EU will be CO₂-free, with 72% coming from renewable sources. This transformation is driven by renewable energy cost reductions and the EU Emissions Trading System (ETS).
  Conventional thermal power plants will operate significantly less, mainly as back-up power unless equipped with carbon capture and storage (CCS). CCS-equipped plants will account for 8% of net electricity generation by 2050.

• Sectoral Trends:

  • Residential and Services:
    Electricity demand in these sectors will grow by 4.2% by 2050. Electric heat pumps and air conditioning will almost double consumption, while conventional heating will decline.
    Efficiency gains in lighting and appliances will offset rising usage.

  • Transport:
    Energy use in transport is expected to stabilise, with electric vehicles (EVs) and efficiency improvements in internal combustion engines reducing energy demand.
    Freight energy demand is projected to increase by 17%, but passenger transport savings will more than offset this.

  • Industry:
    Despite a 60% increase in economic activity, industrial energy consumption will only grow by 6%.
    CO₂ emissions will continue to decline due to electrification, distributed heating, and less carbon-intensive energy carriers.
    From the 2030s, CCS adoption will accelerate the emission reduction pace.

• Costs and Investment:
  Energy-related operating and maintenance (O&M) costs will increase by 34% per unit of energy consumed, but relative to GDP, these costs will decrease from 12.2% in 2015 to 9.8% in 2050.
  Total investment expenditure over the period 2016–2050 is expected to reach 72.5 trillion €, representing 11.5% of cumulative GDP.
  Most investment is in non-energy-related equipment such as vehicles and appliances.

Key Assumptions and Policies

• The scenario assumes no new policies after 2017, but includes the existing policies and technological progress in place.
• EU Emissions Trading System (ETS) price developments and fossil fuel prices are key drivers of the energy system evolution.
• The Energy Performance of Buildings Directive and efficiency improvements in energy-consuming technologies are central to reducing energy and emissions demand.

Technology Dynamics

• Renewables will dominate the power sector, with solar and wind becoming increasingly cost-competitive.
• Flexible storage (e.g., batteries and pump storage) and load following capabilities (e.g., EV charging and hydrogen production) will support the integration of intermittent renewables.
• Electrification of end-use sectors is a major driver of decarbonisation, enabling sector coupling and reduced carbon intensity.

Policy Context and Purpose

• The Central scenario serves as a reference point for comparing alternative policy scenarios.
• It reflects the ongoing impact of existing policies and technological trends, but does not account for the 2030 climate and energy framework or the 2050 climate neutrality objective.
• The POTEnCIA model was developed in collaboration with national experts and is based on the JRC-IDEES database, which provides detailed historical and current energy system data.

Structure and Approach

• POTEnCIA uses a hybrid partial equilibrium approach, combining behavioural decisions with optimisation.
• It incorporates techno-economic data, non-linear relationships, and dynamic market interactions.
• The model uses representative agents to simulate the energy system, capturing investment decisions through discrete choice modelling.
• Capital stock vintages are tracked dynamically using a perpetual inventory model, allowing for accurate representation of energy system structures over time.

Conclusion

• The Central scenario confirms that the EU is on a declining path for both energy use and CO₂ emissions, but will miss mid-century climate neutrality targets.
• Additional policies and measures are needed to align with the Paris Agreement and the EU's 2050 climate neutrality objective.
• Sector coupling and electrification are key enablers for reducing carbon intensity in various sectors.
• The POTEnCIA model provides a transparent and detailed analysis of the EU energy system, supporting policy assessment and scenario development.
