Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - The integration of off-grid electricity provision into national electrification strategies is increasingly common in low-income countries, with a focus on decentralized markets for electricity, particularly through pay-as-you-go (PAYGo) solar home systems [6][11][19] - A significant subsidy implemented by the Togolese government in 2019 reduced usage costs for solar home systems by 17.8% to 41.7%, leading to a dramatic increase in adoption rates, especially for smaller systems [15][16][49] - The study highlights the importance of usage prices in the electrification decisions of low-income households, indicating that high intensive margin prices limit the adoption of solar home systems [6][16][22] Summary by Sections Introduction - Extending the electrical grid to rural areas is often fiscally unsustainable in low-income countries, prompting a shift towards decentralized electricity provision, particularly solar energy [11][12] Background and Context - In 2017, only 35% of Togo's population had access to electricity, with a stark contrast between urban (74%) and rural (5%) households [25] - The CIZO initiative aimed to increase rural electrification rates to 40% by 2022, targeting the electrification of 300,000 households [26][62] Empirical Strategy - The report utilizes administrative data from a major solar company in Togo to measure the impact of the subsidy on the adoption of solar home systems, employing event studies and two-way fixed effects specifications [39][49] Results - The subsidy led to an increase in overall adoption by approximately 122%, with small systems seeing a 240% increase and large systems a 66% increase in adoption rates [49][50] - The findings suggest that low adoption rates of solar home systems are primarily due to low benefits at market prices rather than credit constraints [16][22] Theoretical Framework - A theoretical model is developed to understand the conditions under which the effects of subsidies in Togo may generalize to other contexts, emphasizing the unique cost structures of decentralized solar electricity [17][73] Conclusion - The report concludes that while the subsidy significantly increased the adoption of solar home systems in Togo, the effects may not be replicable in other decentralized energy markets due to varying demand fundamentals and cost structures [91][92][93]
