In many developing countries, theft remains a significant obstacle to ensuring proper public service provision and access. We argue that social acceptability of theft constitutes an understudied barrier to curbing power theft. Using a conjoint experiment, we study perceptions of theft in the form of using illegal wires, katiya, among rural and urban households in Uttar Pradesh, India (n = 1800). Social acceptability of theft is influenced by the income and electricity supply quality contexts of offenders. For a 1000-rupee (approx. 15 USD) income difference between hypothetical vignette agents, the odds of choosing a higher acceptability rating for an offender increases by 11%. One fewer hour of electricity supply received by the vignette person would increase the acceptability of their theft activity by 4%. The majority of respondents chose a warning as the appropriate punishment severity; income and supply quality distinguish the odds of choosing higher punishment categories. While there exists a sense of social reprimand for stealing power, desired punishment is nuanced and context-dependent.
