Electricity Access in Primary Schools by Country (2026)

Access to electricity in primary schools is a fundamental indicator of educational infrastructure quality and a key component of SDG Target 4.a, which aims to build and upgrade education facilities that provide safe, inclusive, and effective learning environments. This indicator measures the proportion of primary schools with access to electricity, a core component of SDG Indicator 4.a.1, tracked by the UNESCO Institute for Statistics. This comprehensive analysis examines electricity access rates in primary schools across 178 countries, providing 2026 projections based on individual country assessments and historical development patterns from 2000 to 2025.

Global Electricity Access Patterns

Global electricity access in primary schools shows dramatic variation, from universal coverage in 111 countries to critical infrastructure gaps in low-income nations. As of 2026, an estimated 62% of countries have achieved or maintained 100% electricity access in their primary schools, while 13 countries still struggle with coverage below 40%. The data reveals that electricity infrastructure in schools has expanded significantly over the past two decades, driven by national electrification programs, international development initiatives, and recognition of electricity as essential for modern education delivery.

The highest-performing regions include Europe, North America, the Gulf states, and East Asia, where universal or near-universal electricity access has been maintained consistently. Countries like Germany, Japan, Australia, and the United Arab Emirates have sustained 100% coverage for over two decades. Meanwhile, rapidly developing nations such as Bangladesh (97.5%), India (98.0%), and Nepal (100.0%) have achieved remarkable progress, transforming their educational infrastructure through massive electrification campaigns between 2012 and 2026.

Regional Challenges and Success Stories

Sub-Saharan Africa presents the most significant challenges, with countries like Central African Republic (4.0%), South Sudan (10.0%), Burundi (10.0%), and DR Congo (11.0%) facing severe electricity access constraints. These low coverage rates are associated with broader infrastructure challenges, ongoing conflicts, limited public investment, and the difficulties of extending electrical grids to rural and remote areas where many primary schools are located. However, even within this region, success stories emerge: Rwanda has achieved 75.0% coverage through focused infrastructure development, while Ethiopia reached 48.0% despite starting from just 7.8% in 2013.

Middle-income countries demonstrate diverse trajectories. Latin American nations like Brazil (98.5%), Chile (99.5%), and Peru (99.0%) approach universal coverage, benefiting from decades of infrastructure investment and relatively high urbanization rates. In contrast, some countries have experienced volatility or stagnation. Colombia's coverage fluctuated between 85-96% from 2013 to 2022, while Haiti's infrastructure has deteriorated to an estimated 35.0% due to ongoing crises and natural disasters.

Island nations and small states show varied patterns. High-income territories like Aruba, Cayman Islands, and Cook Islands maintain 100% coverage, while lower-income Pacific islands face geographic challenges. Papua New Guinea reaches only 26.0% coverage due to its mountainous terrain and dispersed population, whereas Samoa and Tonga have achieved universal access despite similar geographic constraints, demonstrating the impact of targeted investment and smaller scale.

Methodology

This analysis provides 2026 electricity access projections for primary schools across 178 countries based on comprehensive manual assessment of historical data, development trajectories, and country-specific factors. The methodology prioritizes transparency, accountability to source data, and realistic projections grounded in individual country contexts.

Data Source and Coverage: The analysis uses UNESCO Institute for Statistics (UIS) data on the proportion of primary schools with access to electricity, covering the period 2000-2025 (Indicator SCHBSP.1.WELEC, part of SDG Indicator 4.a.1). This indicator measures the proportion of primary schools with access to electricity as a fundamental component of educational infrastructure quality. The dataset includes 178 countries with varying data availability: some countries have annual data from 2000-2025, while others have only one or two data points. Data recency varies significantly, with 89 countries having 2024 or 2025 data, while 89 countries have older data ranging from 2009 to 2023.

Manual Analysis Approach: Unlike automated projection methods, this analysis employed individual manual assessment for all 178 countries. Each country received dedicated analysis considering its unique historical pattern, baseline value, regional context, income level, conflict status, geographic challenges, and infrastructure development trajectory. This approach ensures projections reflect real-world constraints and opportunities rather than applying uniform growth assumptions across diverse contexts.

Baseline Value Respect: All projections respect the most recent available data as the baseline, with changes limited to ±2-3 percentage points from the latest value in most cases. This conservative approach acknowledges that electricity infrastructure changes gradually and that dramatic shifts require extraordinary circumstances. For example, Argentina's projection of 98.5% (2026) from 97.7% (2023) reflects a modest +0.8 point increase appropriate for near-saturation levels. Countries showing historical volatility (e.g., Botswana jumping from 44.1% in 2021 to 97.9% in 2022) were assessed for methodology changes, with projections based on post-adjustment data.

Saturation Effects: Countries with coverage above 90% receive minimal growth projections, typically +0.3 to +1.5 percentage points, recognizing that reaching the final 5-10% of schools involves the most remote, costly installations. For example, Chile (99.2% to 99.5%), Mexico (98.0% to 98.5%), and India (97.3% to 98.0%) all show modest gains reflecting saturation dynamics. Conversely, countries in the 40-70% range often show larger absolute gains (e.g., Kenya 79.9% to 82.0%, Nigeria 67.0% to 69.0%) as mid-range expansion is typically more cost-effective than final-mile coverage.

Old Data Assessment: For the 89 countries with data older than 2024, projections incorporated development trajectory analysis rather than ignoring the time gap. This involved assessing: (1) the country's income level and typical infrastructure development pace, (2) regional benchmarking against similar countries with recent data, (3) conflict or crisis impacts that might have halted or reversed progress, and (4) sector-specific factors like national electrification programs or education infrastructure initiatives. For example, Angola's projection of 28.0% from 22.4% (2016) reflects 10 years of oil-revenue-supported infrastructure development, while Haiti's projection of 35.0% from 38.0% (2016) reflects infrastructure deterioration due to ongoing crises.

Regional Benchmarking: Countries were assessed within their regional contexts to ensure projections align with comparable nations. For instance, Central American countries (Guatemala 97.0%, Honduras 95.0%, Nicaragua 98.0%) show convergence toward near-universal coverage, while West African nations (Benin 35.0%, Burkina Faso 30.0%, Mali 53.0%) reflect the region's persistent infrastructure challenges. This approach prevents unrealistic outliers while respecting individual country circumstances.

Conflict and Crisis Impacts: Countries experiencing ongoing conflicts or major crises received conservative projections reflecting infrastructure constraints. Afghanistan (16.1% to 18.0%) shows minimal growth due to deteriorating security since 2019. Syria (89.0% to 90.0%) maintains relatively high coverage as urban infrastructure remains functional despite conflict. Yemen's slow growth from 42.0% to 43.0% illustrates how prolonged conflict is associated with constraints on even basic infrastructure maintenance and expansion. Haiti (38.0% to 35.0%) is projected to decline due to ongoing political and security crises.

Income Level and Development Capacity: Projections incorporated countries' economic capacity to fund infrastructure. High-income countries maintaining 100% coverage (e.g., Germany, Japan, Singapore) are projected to sustain universal access. Upper-middle-income countries approaching universal coverage (Brazil 98.5%, Mexico 98.5%, South Africa 94.5%) show continued progress. Lower-middle-income countries demonstrate varied trajectories based on governance and priorities: Vietnam maintains 100%, while Pakistan reaches only 70.0%. Low-income countries face the slowest progress: Niger (21.0% to 23.0%), Madagascar (27.9% to 30.0%), reflecting severe resource constraints.

Geographic and Infrastructure Factors: Island nations and countries with challenging terrain received projections accounting for higher infrastructure costs. Papua New Guinea (23.9% to 26.0%) faces mountainous terrain and dispersed populations. Small island developing states show varied outcomes: high-income territories (Aruba, Cayman Islands) maintain 100%, while lower-income islands (Comoros 51.0%, Vanuatu 64.0%) progress more slowly. Countries with extensive rural populations where grid extension is costly (e.g., Ethiopia 48.0%, Tanzania 47.0%) show moderate gains reflecting the challenge of reaching remote schools.

Electricity Infrastructure Development Context (2000-2026): The 26-year period covered by the data witnessed significant global electricity infrastructure expansion. National electrification rates increased substantially in developing countries, driven by falling costs of grid extension and off-grid solar solutions, international development financing (World Bank, regional development banks), and recognition of electricity as essential for education, health, and economic development. Many countries implemented specific school electrification programs, often supported by international partners. However, progress has been uneven: while Asia and Latin America made dramatic gains, Sub-Saharan Africa continues to face major deficits, and conflict-affected regions saw stagnation or decline.

Projection Validation: All 178 projections were cross-checked for internal consistency, regional alignment, and plausibility given historical trends. Countries projected to reach 100% had demonstrated clear trajectories toward universal coverage (e.g., Nepal, Egypt, Morocco, Paraguay). Countries with modest gains had recent data showing stabilization or slow growth (e.g., Benin, Cameroon, Mozambique). Countries with larger gains had historical patterns supporting accelerated progress (e.g., Bangladesh, Ethiopia, Rwanda). No country was projected to exceed 100% or fall below 0%, and all changes from baseline were justified by specific country circumstances documented in the manual analysis.

Data Limitations: Projections carry inherent uncertainty, particularly for countries with old data (pre-2020) where actual 2026 values may differ significantly from estimates. Methodology changes in data collection can cause apparent jumps or drops unrelated to real infrastructure changes (e.g., Botswana 2021-2022). Conflict, natural disasters, economic crises, or major policy shifts occurring between the latest data and 2026 could substantially alter outcomes. The analysis assumes continued gradual progress for most countries, but disruptions could accelerate or reverse trends. Countries approaching 100% may achieve universal coverage faster or slower than projected depending on political prioritization and financing availability.
