Tonga Electricity Access
Access to electricity as % of population EG.ELC.ACCS.ZS
Tonga's electricity access was 100.98% in 2025, ranked 9th globally. This represents a 1.0% increase from 2024. Data from World Bank, covering 1994–2025.
Overview
Tonga's electricity access stood at 100.98% in 2025, a rise of +0.98pp from 2023. Based on recent trends, this figure is projected to reach 100.98% by 2025. Tonga ranked 9th globally.
Tonga’s electricity‑access rate has risen from 80.00 % in 1994 to 100.98 % in 2025, marking a 31‑year expansion that culminates in the highest recorded level for the country and places it ninth globally. The all‑time peak coincides with the most recent data point, indicating that universal coverage has been achieved without a subsequent decline. By comparison, peer nations such as Mongolia record a slightly lower access rate of 100.76 % and the Marshall Islands marginally higher at 102.22 %, suggesting that Tonga is performing at the upper end of the regional spectrum. The sustained upward trajectory reflects continued investment in grid extension and renewable generation, which have mitigated earlier gaps in remote islands. Maintaining this momentum will depend on reinforcing infrastructure resilience, especially against climate‑related disruptions, to ensure that the near‑universal access level remains stable or improves in the coming decade.
