While energy poverty is a particularly large problem in rural areas, rapid urbanization in developing countries is also raising concerns about energy access in urban areas. How can policymakers improve energy access for the urban poor? We address this question by investigating the use of solar power for improved lighting for urban street vendors. We conduct a field study of the centralized charging station model in Patna, Bihar, India. A solar panel is installed in a marketplace and vendors can rent and charge the batteries of the lights for a daily fee. Our findings reveal potential problems with the approach. Key issues include opposition by local strongmen who operate diesel generators, the difficulty of finding local entrepreneurs to operate the system, vendor misuse of the lights, and physical barriers such as land availability. Policy recommendations include considering the sales of standalone devices and relying on the urban electricity grid for connections.
