The study uses a qualitative Available online 29 November 2018 methodology where primary data is collected through 30 semi-structured interviews with experts representing Keywords: the main electricity sector's stakeholders from public institutions, research institutions, private investors, civil fi Barrier analysis society organizations, development partners, and nancial institutions. A stakeholder-based approach which Renewable energy emphasizes the different perceptions of the stakeholder's groups is used to identify the barriers. Institutional Qualitative research barriers for the diffusion of large-scale solar power technologies are found to be predominant, and they often Stakeholder-based approach trigger financial and technological barriers. The study consolidates the view that foreign investment and Sub-Saharan Africa aid directed to expand electrification in Sub-Saharan Africa need to be reshaped in order to be a driving Tanzania force towards sustainable energy transition in the region. The study argues for the possibility to work on the compatible interests between the pro-renewables development partners and the Tanzanian government (which considers expanding electrification as a political priority) through introducing large-scale solar power projects that help in expanding electrification while being technically and financially supported by the development partners. © 2018 European Commission, Joint Research Centre (JRC).
