The Turkish electricity distribution and electricity supply businesses have been substantial affected by the transition from a vertically integrated public monopoly model to a model of regulated competition with privatized and unbundled firms. We analyze how select elements of sustainability have been and will be affected by this transition. Specifically, we consider transparency of the electricity market as a whole and implications for electricity supply and distribution, the financial soundness of the electricity distribution industry, the quality of electricity delivered by the distributors, and the competitiveness of the electricity supply business. The key finding is that little if any progress toward sustainability has been achieved. We conclude that there remains much for policymakers to do to establish a sustainable market structure.
