Summary of IRENA Report: Planning and Prospects for Renewable Power in North Africa

This report by the International Renewable Energy Agency (IRENA) examines the potential for renewable energy in North Africa, modeling scenarios for power system expansion through 2040. The goal is to evaluate pathways toward reducing reliance on fossil fuels while meeting increasing electricity demand.

Report Context

Authored by Sebastian Hendrik Sterl and others under IRENA guidance
Released in 2023
Focuses on North African countries: Algeria, Egypt, Libya, Mauritania, Morocco, Tunisia

Key Findings

Energy Dependency and Challenges

North Africa relies heavily on fossil fuels (primarily natural gas) for electricity generation
High vulnerability to global fossil fuel price fluctuations and import dependency
Many countries are subsidizing fossil fuel-based power generation

Renewable Expansion Potential

Solar and wind power are expanding with falling installation costs
Solar PV costs dropped from ~$2,000/kW in 2015 to ~$1,300/kW in 2019
Solar potential is abundant across the region, with particularly strong resources in Egypt and Algeria

Modeling Approaches

Uses IRENA's System Planning Test Model for North Africa (SPLAT-N)
Modeled four scenarios varying in fossil fuel investment, battery storage, and hydrogen production
Scenarios enabled analysis of system costs and emission reductions under different policy assumptions

Scenario Analysis

Planned Scenario

Meets current renewable energy targets
Reliance on fossil fuels remains high
Higher unit electricity costs compared to transition scenarios

Transition Scenarios

Three progressively more ambitious scenarios post-2025:

Transition: Higher renewables share, lower fossil fuel generation, significant job creation
Transition + Batteries: Incorporates large-scale battery storage to enable greater renewable integration
Transition + Batteries + H2: Includes hydrogen export potential as additional revenue stream

Policy Recommendations

Strengthen regional interconnections to leverage spatio-temporal complementarity
Develop supportive policies for hydrogen export
Prioritize renewable capacity expansion, especially solar across the region
Address necessary grid investments to handle higher renewable shares

Environmental Impact

A 75% reduction in power sector carbon emissions by 2040 relative to 2020 levels
Significant cumulative CO₂ emission reductions compared to business-as-usual scenarios

Socio-Economic Benefits

Job creation potential through renewable investments
Economic diversification beyond traditional fossil fuel exports
Increased revenue streams through hydrogen exports

The report highlights North Africa's substantial potential to reduce carbon emissions and energy costs while becoming a renewable energy hub, primarily through solar and wind power expansion coupled with strategic storage and hydrogen production.
