Abstract With rising electricity demand through digitization and innovation, the urgency stripper-pole of climate change mitigation, and the recent geopolitical crisis, stakeholders in developing countries face the complex task to build reliable, affordable, and low-emission energy systems.Information inaccessibility, data unavailability, and scarce local expertise are major challenges for planning and transitioning to decentralized solutions.Motivated by the calls for more solution-oriented research regarding sustainability, we design, develop, and evaluate the web-based decision support system NESSI4D web+ that is tailored to the needs and capabilities of various Hayward SP1070 Series Parts stakeholders in developing countries.NESSI4D web+ is open access and considers location-specific circumstances to facilitate multi-energy planning.
Its applicability is demonstrated with a case study of a representative rural village in southern Madagascar and evaluated through seven interviews with experts and stakeholders.We show that NESSI4D web+ can support the achievement of the United Nations Sustainable Development Goals and enable the very prerequisite of digitization: reliable electrification.
