Introduction

The potential impacts of climate change in the energy sector are varied across energy supply, transmission, and distribution infrastructure. For thermal fossil fuel–fired power plants and hydropower electricity projects, the effect of climate change on water resources is the critical issue. Climate change may also affect renewable energy, such as solar and wind. Increased temperatures can reduce the efficiency of solar photovoltaics and concentrated solar power requiring water cooling. Increased cloudiness in some areas with more frequent rainfall would reduce solar generation capacity. Extreme weather events, such as hail and heat waves, can damage and more quickly deteriorate solar materials. For wind power, changing weather patterns could change wind speeds and alter power outputs. Floods and coastal storm surge can physically damage all types of power generation assets. For electricity transmission and distribution infrastructure, increases in temperature can lead to greater electricity losses and reduce the capacity of lines.

This energy sector guidance note was prepared by the World Resources Institute (WRI) for the Islamic Development Bank (IsDB) to enable IsDB project teams to integrate information on climate risks into project design. It applies to energy sector projects involving physical assets, largely focusing on the electricity sector.

After a brief background on projected climate changes in regions and their projected impacts on the energy sector (Section 2), Section 3 explains the purpose of this note within a broader climate risk management process. It describes the steps involved in managing a project’s climate change risks—beginning with climate risk screening, followed by project impact and adaptation assessments, and ending with project implementation. Section 4 then describes the process of determining potential climate impacts on energy sector projects and identifying adaptation options to address those impacts. Section 5 presents an approach to evaluate adaptation options, and Section 6 concludes with case studies (Tajikistan and Bangladesh) that demonstrate a practical example of this approach.

Supporting Climate Risk Management Process in the Energy Sector

This guidance note will support the broader climate risk management process, which begins with climate risk screening and concludes with project implementation.

  1. The first phase of the process is climate risk screening.
    • IsDB plans to begin using Acclimatise Aware, a climate risk screening tool, for this phase. In addition to generating an overall climate risk ranking, Aware identifies key climate risk areas for the project, based on project category and location.
    • Project teams can use this information, along with expert judgment and other available climate data, to determine the climate hazards most likely to be relevant for a project. The World Bank’s Climate Change Knowledge Portal and The Nature Conservancy’s Climate Wizard are two examples of publicly available tools for identifying location-specific changes in climate conditions.
  2. If the initial climate risk screening using Aware indicates that a project has some level of climate risk, a project impact assessment follows. Climate risk screening and project impact assessment together establish the climate change vulnerability context of a project.
  3. That climate change vulnerability context informs the adaptation assessment that follows, which aims to identify those measures best suited to reduce climate vulnerability, thereby establishing a direct link between specific project activities and the overall objective of reducing climate vulnerability.

This guidance note is meant to support project impact and adaptation assessments of the climate risk management process.

Identifying Potential Impacts

The guidance, with decision trees, illustrates the process of identifying project vulnerabilities and adaptation options for projects involving:

  • thermal power
  • hydroelectric power
  • solar and wind power
  • transmission and distribution

Project teams must be aware of several important caveats in using the decision trees:

  • The trees provide a generalized overview of potential impacts, but climate change is likely to affect different types of projects across different regions in diverse and highly context-specific ways.
  • The different climate drivers cannot be viewed in isolation. Instead, project teams must consider how the various drivers interact with each other. At the same time, a variety of nonclimate factors, such as population growth, land-use change, economic development, and urbanization, could pose significant challenges to the energy sector.
  • The guidance primarily focuses on the potential direct and indirect physical impacts of climate change. Physical impacts could also lead to any number of nonphysical impacts, but these tend to be highly context- and project-specific.

Upon identifying potential physical project vulnerabilities, project teams should consider whether such vulnerabilities could have follow-on consequences for a particular project.

Adaptation Options

Identifying Adaptation Options

Once a project team determines potential project vulnerabilities, it can proceed to identifying possible adaptation solutions.

An important preliminary step is defining the objective of adaptation. In setting objectives, project teams should consider:

  • what vulnerabilities they seek to address
  • what their desired outcomes are

Once the team defines its adaptation objectives, it should strive to compile a wide range of measures to meet those objectives.

Building resilience often requires a combination of hard and soft adaptation measures, as well as engineered and naturebased infrastructure options, because the underlying causes of vulnerability are often diverse.

  • In identifying adaptation options, project teams should seek to develop a wide range of options.

Consulting with a variety of stakeholders (including community and nongovernmental organizations, environmental specialists, engineers, and others) can help to identify a comprehensive list of adaptation options.

  • Finally, in identifying adaptation options, project teams should remember that adaptation measures will ideally be aligned with existing country or sector resilience plans.

Appraising Adaptation Options

For evaluating and prioritizing among adaptation options, the guidance describes an approach combining:

  • Multi-criteria analysis:it allows for a qualitative and comparative assessment of different adaptation options. The project team would first identify the appropriate criteria for the given project, such as the following:
    • Functional effectiveness
    • Technical feasibility
    • Affordability
    • Stakeholder acceptability
    • Ease of implementation
    • Flexibility/robustness
    • Cobenefits
  • The remaining options can then be evaluated in greater detail using a quantitative economic assessment. Two possible techniques for economic assessment of adaptation options are:
    • cost-benefit analysis
    • cost-effectiveness analysis
  • Rather than using economic assessments to identify the optimal solution for a single, best-guess projection, decision making under uncertainty is focused on increasing the robustness of a project. For example, by:
    • Incorporating safety margins into adaptation planning
    • Stress testing the outcomes of economic assessments using sensitivity analysis
    • Identifying no-regret and low-regret measures to implement in the near term that will yield benefits regardless of the nature and extent of climate change

Case-studies

The guidance note was developed by the IsDB Climate Change Division (Dr. Ahmed Al Qabany, Olatunji Yusuf) under the general oversight of Dr. Mansur Muhtar, Vice President (Country Programs) and May Babiker, Acting Director, Resilience and Social Development Department. The guidance note was reviewed and received input from Mohammed Al Sayed (Manager, Economic Infrastructure Division, IsDB), Hussain Mogaibel (Economic Infrastructure Division, IsDB), Dr. Haruna Gujba (Climate Change Division, IsDB), Craig Davies (European Bank for Reconstruction and Development [EBRD]), and Falzon James (EBRD). The main author of this guidance note was the World Resources Institute (WRI), technical consultant to the Islamic Development Bank.
