The growing complexity of energy systems has increased the need for frameworks that can assess performance beyond traditional national indicators. While research on the Energy Trilemma is expanding, most studies focus on national and cross-country analyses and pay little attention to provincial and local energy systems. This study fills that gap by creating a Provincial Energy Trilemma Index (PETI) framework. This framework allows for a localized assessment of energy security, energy equity, and environmental sustainability. Using the PRISMA systematic literature review approach, the study analyzed 67 peer-reviewed articles from the Scopus database related to Energy Trilemma assessments, sustainability transitions, composite energy indices, and decentralized energy systems. The review used thematic synthesis and indicator frequency analysis to identify common indicators and assessment methods relevant for provincial use. The findings highlighted the electrification rate, electricity affordability, renewable energy share, supply reliability, carbon emissions, and energy efficiency as the most common and applicable indicators for provinces. The review also showed that existing Energy Trilemma studies are methodologically disjointed and not well-localized. In response, the study suggests PETI as a flexible framework that combines well-founded and measurable indicators across the three main dimensions of the Energy Trilemma. The framework offers a basis for provincial benchmarking, sustainability monitoring, and informed energy planning within decentralized and diverse energy systems.
