TIMES-Europe: An Integrated Energy System Model for Analyzing the Transition to a Low-Carbon Economy

Integrated energy system models are powerful tools for quantitatively exploring the future development of energy systems under various climate policy scenarios. TIMES-Europe, a novel multi-sectoral model based on the TIMES modeling environment, offers a detailed representation of Europe’s energy landscape—spanning all member states and neighboring countries—to analyze the continent’s shift to a low-carbon future.

Modeling Approaches

TIMES-Europe employs a linear optimization approach to minimize the discounted total energy system costs over its full time horizon. The model computes the energy system parameters that minimize this objective function, which includes annualized investment costs, operational and maintenance expenses, trade costs, and other relevant expenditures. User-specified constraints capture real-world boundaries, such as limits on technology deployment or policy measures like feed-in tariffs.

Model Components

The model contains a detailed representation of the upstream and power sectors, as well as all major energy demand segments, including end-use technologies and energy service demands, for each individual country in the EU-27 plus the UK. TIMES-Europe also includes electric interconnections and gas pipeline infrastructure between these nations, enabling the analysis of energy commodity trade.

On the supply side, the model encompasses fossil energy resources, renewable potentials, fuel production, and power/heat conversion facilities. The demand side covers residential, industrial, commercial, agricultural, and transportation sectors, with end-use technologies matching the energy service demands.

Applications of Integrated Energy System Models

Models like TIMES-Europe are invaluable for policymakers navigating Europe’s energy transition. They can generate strategic decarbonization insights, assess the impact of climate policies, and explore the role of various low-carbon options—from wind and solar to hydrogen and battery storage—in achieving a net-zero economy.

Crucially, TIMES-Europe’s broad geographical scope, encompassing both the EU and its neighboring regions, allows for analyzing the complex interactions between national and European energy and climate policies. This helps identify instances where they may reinforce or counteract each other, a critical consideration given the prominence of the EU Emissions Trading System (ETS) in driving industrial and power sector decarbonization.

Low-Carbon Energy Transition

The transition to a low-carbon economy is a strategic priority for Europe as it seeks to meet the goals of the Paris Agreement. Achieving net-zero emissions by 2050 and a 55% reduction by 2030 (relative to 1990 levels) are legally binding targets under the EU Climate Law.

Decarbonization Strategies

To reach these ambitious targets, Europe is pursuing a multifaceted approach. The EU’s Fit-for-55 legislative package proposes transforming the ETS, setting more stringent emissions reduction goals for non-ETS sectors, and establishing a 40% renewable energy target for 2030. The recently unveiled REPowerEU plan further aims to reduce dependency on Russian fossil fuels by accelerating the energy transition, with a new 45% renewable energy target for 2030.

Policy Considerations

Navigating this energy transformation requires carefully balancing various policy objectives, from energy security and affordability to industrial competitiveness and environmental sustainability. TIMES-Europe is well-equipped to explore these nuances, shedding light on how national and EU-level policies can reinforce or conflict with each other.

Technological Innovations

Realizing Europe’s green energy ambitions will rely on continuous advancements in renewable energy technologies, energy storage, power-to-X solutions, and other low-carbon innovations. TIMES-Europe’s detailed representation of these emerging technologies allows for in-depth assessments of their evolving role and impact on the future energy system.

TIMES Energy System Model

TIMES-Europe is built using the TIMES modeling environment, a widely adopted framework for developing technology-rich, linear optimization models of energy systems. The model’s reference energy system is configured using a collection of processes, commodities, and commodity flows, which together represent the various supply and demand sectors.

Model Structure

The model covers the entire European energy system, including all 27 EU member states and a broad set of neighboring countries. It encompasses the upstream, power, industrial, residential, commercial, agricultural, and transportation sectors, as well as the interconnections between them.

Data Requirements

TIMES-Europe’s extensive database describes the current European energy landscape, including the characteristics of installed supply technologies and present energy service demands. It also incorporates detailed projections of future supply and end-use technologies, drawing from sources like the JRC-IDEES, ENSPRESO, and Eurostat databases.

Scenario Analysis

By defining different scenario assumptions, TIMES-Europe can generate high-level strategic insights and detailed policy recommendations for both national and EU-level decarbonization efforts. These scenarios can explore the role of various factors, such as technology costs, resource potentials, policy instruments, and macroeconomic conditions, in shaping the energy transition.

Energy System Transformation

The transition to a low-carbon energy system in Europe will require substantial changes across all sectors, from power generation and industrial processes to transportation and building energy use.

Sector Coupling

TIMES-Europe’s integrated, multi-sectoral approach is crucial for analyzing the complex interactions between different energy end-uses and supply options. This enables the model to assess the synergies and trade-offs involved in the electrification of end-uses, the production and utilization of hydrogen, and the deployment of biofuels and other synthetic fuels.

Renewable Integration

The model’s detailed representation of renewable energy technologies, such as wind, solar, and hydropower, allows for in-depth studies on their evolving role in the future European energy mix. This is particularly important given the EU’s ambitious targets for renewable electricity generation and the need to ensure grid reliability and flexibility.

Emissions Reduction

TIMES-Europe comprehensively tracks the greenhouse gas emissions from various sectors, including not only energy-related emissions but also process emissions from industrial activities. This enables the model to explore diverse decarbonization pathways, including the deployment of carbon capture and storage (CCS) technologies, to achieve the EU’s net-zero goals.

Integrated energy system models like TIMES-Europe are invaluable tools for policymakers and stakeholders navigating Europe’s complex energy transition. By providing a detailed, technology-rich representation of the continent’s energy landscape, TIMES-Europe can generate strategic insights, assess policy impacts, and explore the role of various low-carbon innovations in achieving a sustainable, secure, and affordable energy future. As the EU continues to shape its long-term energy and climate policies, this model will be an essential resource for informing the difficult decisions ahead.
