Climate Vulnerability Assessments in Albania's Energy Sector

Core Content

This document presents a Climate Vulnerability Assessment for Albania's energy sector, highlighting the country's exposure to climate change and the need for adaptation strategies. The assessment is part of the Country Energy Sector Vulnerability Assessments Program (CESVAP), led by the Energy Sector Management Assistance Program (ESMAP), which aims to support countries in preparing for climate impacts in the energy sector.

Main Points

• Climate Vulnerability: Albania's energy sector is highly vulnerable to climate change due to its reliance on hydropower, which is sensitive to rainfall variability and droughts. Climate change is expected to exacerbate these issues, leading to reduced electricity generation and increased energy import dependency.

• Key Risks:

  • Fluctuations in rainfall impact hydropower production, causing electricity shortages and load shedding.
  • Transmission and distribution inefficiencies (33% losses in 2008) further reduce energy availability.
  • Agricultural water use competes with hydropower, especially during summer months.
  • Higher temperatures increase summer cooling demand while reducing hydropower output.

• Adaptation Framework: The Climate Vulnerability Assessment Framework is used to identify and prioritize climate risks, adaptation options, and conduct cost-benefit analysis. This approach involves stakeholders and is based on qualitative/semi-quantitative methods.

• National Energy Strategy (NES): Albania's draft NES outlines an "active scenario" to improve energy security through diversification of energy sources (solar, wind, biomass, and thermal) and regional interconnections. However, it does not account for climate change impacts on new energy assets.

• Climate Impacts by 2050:

  • Large hydropower plants (LHPPs) could see a 15% reduction in output.
  • Small hydropower plants (SHPPs) may face a 20% reduction.
  • Thermal power plants (TPPs) may experience 1% efficiency loss due to rising temperatures.
  • Solar power may see a 5% increase in output due to decreased cloudiness.

• Adaptation Measures:

  • Improved weather forecasting and real-time monitoring of river levels to optimize hydropower operations.
  • Redimensioning SHPPs to better manage seasonal water flows.
  • Enhanced energy efficiency through reducing system losses and promoting energy-saving technologies.
  • Upgraded emergency contingency plans (ECPs) to address increased precipitation intensity and flood risks.

• Intersectoral Synergies:

  • Water management is a key area for adaptation, with 640 dams and 0.6 billion m³ of storage capacity.
  • Sediment management through quarrying and dredging can support river basin management.
  • Integration of energy, agriculture, and water sectors is essential to ensure efficient resource use and climate resilience.

• Cost-Benefit Analysis (CBA):

  • The CBA identifies upgrading existing LHPPs and SHPPs as the most economical options for the medium term.
  • New SHPPs and CCGTs (combined cycle gas turbines) are also considered viable options.
  • The Net Present Value (NPV) of these options is presented in Figure 4, showing the financial and environmental sustainability of different adaptation strategies.

Key Information

• Energy Mix: Albania's energy production is dominated by hydropower (90% of domestic electricity), with thermal power and renewables playing a growing role.
• Energy Shortfall: By 2030, a 350 GWh per year supply-demand gap is expected, equivalent to 50 MW of power. By 2050, this could increase to 740 GWh or 3% of total demand.
• Adaptation Needs: The document emphasizes the importance of early consideration of climate risks in energy planning to ensure long-term resilience and sustainable development.
• Supporting Organizations: The assessment was supported by ESMAP, TFESSD (Trust Fund for Environmentally & Socially Sustainable Development), and The World Bank.

Conclusion

Albania's energy sector faces significant climate-related risks, particularly from droughts, seasonal variability, and increased cooling demand. The Climate Vulnerability Assessment provides a framework for adaptation, highlighting the need for improved forecasting, efficiency upgrades, and intersectoral coordination. These efforts are crucial for ensuring energy security, economic development, and resilience to climate change.
