ISTANBUL — A recent overhaul of Türkiye’s electricity market settlement mechanism has prompted manufacturers to reassess planned investments in renewable energy projects, with industry representatives warning that the new system could significantly alter the economics of self-generation investments.

The changes relate to the Day-Ahead Electricity Market (GÖP) and the hourly netting (mahsuplaşma) mechanism applied under the Renewable Energy Resource Guarantee (YEK-G) and distributed generation framework. Previously, many industrial companies were able to offset electricity generated by their solar power plants against consumption over a broader settlement period, improving project returns.

Under the revised rules, electricity generation and consumption will now be reconciled on an hourly basis, reducing the financial benefits for facilities whose production and consumption profiles do not align within the same hour. As a result, companies with rooftop and on-site solar installations may receive lower compensation for excess generation exported to the grid while purchasing electricity at different prices when their production falls short.

Industry executives told Patronlar Dünyası that the shift has upended investment calculations for many planned renewable energy projects. According to market participants, feasibility studies prepared under the previous settlement model may no longer deliver the expected payback periods, forcing companies to revisit investment decisions or delay projects until the financial impact becomes clearer.

Business groups have called for authorities to reassess the implementation of the hourly settlement system or introduce transitional measures, arguing that maintaining investment incentives is essential for accelerating industrial decarbonization and expanding renewable energy capacity.
