Floating and offshore renewable energy systems, which have a bright future and tremendous potential, have recently been installed worldwide. According to the potential study for artificial reservoirs in Türkiye, conducted at the beginning of the thesis preparation, covering 10% of the suitable reservoir surfaces with these floating PV systems could generate 125 TWh of electricity, meeting over one-third of the Türkiyes current electricity needs. Beyond inland artificial reservoirs, offshore areas hold even more potential. Hybrid systems, a relatively new concept, are techno-economically more feasible than conventional ones. One of the drawbacks is the impact of the offshore systems on the marine and underwater ecosystem. Artificial reefs have been proven to be beneficial in invoking the ecosystem underwater. In this thesis, an offshore trio-hybrid system consisting of solar and wind power plants along with artificial reefs was presented for a coastal region. A preliminary conceptual design, considering environmental loads for the hybrid offshore floating system and the electricity generation generated, was revealed. The mooring system, which is an essential part of floating designs, included artificial reef wires. For the hybrid system proposed in this study with an approximate total installed capacity of 1,056 kW, it can be demonstrated that an average annual generation of over 2,000 MWh can be achieved. The generation would have a payback period of 6.5 years when applied at 13.3 USD-cent tariff, as previously implemented in Türkiye. The interdisciplinary study also covers Türkiye electricity mix, road to offshore system and provides relevant recommendations for policy development drawn.
