UC5: Adaptation to Landslide and Flood Impact on Power and Gas Network Reliability in Slovenia

Objective

UC5 focuses on analyzing the impact of landslides and climate change-driven flooding on the reliability of Slovenia’s power and gas networks. Slovenia faces increasingly frequent extreme weather events, such as droughts and floods, due to climate change, which poses significant risks to its energy systems.

Background

In Slovenia, one-third of electricity is generated by hydropower plants, and the largest power plant – the Krško nuclear power plant – is located near the Sava River, the country’s largest river. Flooding can disrupt the operation of energy systems, compromising the reliability of energy supply. The UC5 project aims to deepen understanding of how landslides and floods impact Slovenia’s power system while providing recommendations for adaptive measures to mitigate these risks.

Methodology

Within UC5, real network data will be used to model the transmission and distribution network and to simulate the impact of limited adaptation measures on Slovenia’s energy supply reliability. The analysis will include calculating network reliability indices, focusing on potential consequences if adaptation efforts are insufficient. The main stakeholders in this use case will include the European Union Agency for the Cooperation of Energy Regulators (ACER), ENTSO-E, and ELES, Slovenia’s electricity network operator.

Key Outputs for UC5

1. Reliability Impact Assessment Report

A comprehensive report detailing the impact of landslides and floods on the reliability of Slovenia’s power and gas networks. This assessment will use network reliability indices to quantify potential disruptions and highlight vulnerable areas within the transmission and distribution networks.

2. Adaptation Strategies and Recommendations

A set of tailored adaptation strategies to improve resilience in Slovenia’s energy systems. These recommendations will focus on measures to mitigate risks posed by landslides and floods, considering both technical and operational adjustments in collaboration with key stakeholders.

3. Simulation Model of Climate Impact on Energy Networks

A simulation model using real network data that demonstrates the projected impact of extreme weather events on Slovenia’s energy supply reliability. This model will serve as a decision-making tool for analyzing and planning future adaptation actions.

4. Data-Driven Insights and Decision Support

Data-driven insights into network vulnerabilities to climate-induced events, which will support decision-makers in assessing critical areas and prioritizing investments in infrastructure resilience.

These outputs will contribute to bolstering Slovenia’s energy infrastructure against climate risks, ensuring continuity and reliability in power and gas supply under changing climate conditions.
