Electricity Access
Roughly 770 million people lack electricity access — down from 1.4 billion in 2010. Sub-Saharan Africa now accounts for ~75% of those without access; in some African countries less than 30% of the population is connected. Solutions are diverging: grid extension remains primary in densely-populated areas; mini-grids and solar home systems (SHS) increasingly serve remote populations.
Key insights
India's electrification was the largest success story
India added electricity access for ~700 million people between 2000 and 2024 — perhaps the largest such gain in history. Saubhagya scheme (2017-2019) achieved near-universal connections. Reliability remains uneven — many connected households still face frequent outages. The achievement is access; quality is the next frontier. Distribution losses, billing issues, and informal connections complicate the picture.
Sub-Saharan Africa is the remaining frontier
Despite gains, ~580 million sub-Saharan Africans lack electricity. Rapid population growth means absolute number of unserved hasn't fallen as fast as access rates have risen. Solutions: grid extension in higher-density areas, mini-grids in rural clusters, solar home systems (SHS) at household level. Pay-as-you-go solar (M-KOPA, BBOXX, Bboxx, Greenlight Planet/Sun King) has reached 50+ million households across Africa with mobile-money-enabled financing.
Off-grid solar is reshaping access economics
Solar PV costs have collapsed; LED lighting is highly efficient. SHS providing 50-200W of capacity can power lights, phone charging, fans, TV, small fridge — meaningful service for $5-30/month under PAYG models. Estimates: 200+ million Africans served by off-grid solar products. Grid extension to remote areas often costs more per household than equivalent SHS service. Hybrid grid+SHS futures emerging.

Methodology & caveats
Defining 'access'
SDG 7.1 defines access as ability to use electricity for basic needs. Multi-Tier Framework (MTF) by World Bank distinguishes tiers from 0 (none) to 5 (high reliable use). Most access statistics use Tier 1+ (basic lighting and phone charging) — a low bar. Many 'connected' households experience load shedding or low capacity that wouldn't meet higher tiers.
Mini-grid economics
Mini-grids serve clusters of households/businesses with local generation (often solar+battery+sometimes diesel backup). Capital costs $500-1500 per connection. Tariffs often 2-3× grid tariffs but with reliable service. PAYG and pre-paid metering keep collection efficiency high. The economics work best for medium-density rural areas not served well by central grid or individual SHS.
Why some countries lag
Conflict-affected states (South Sudan, Yemen, Afghanistan, DRC conflict zones) have lowest access rates. Beyond conflict: weak utilities, low electrification investment, dispersed rural populations. Reform packages (commercialize utilities, attract private investment, rural electrification agencies) have worked in some contexts. Political-economy obstacles (tariff levels, vested interests) often dominate.
