Economic Assessment of Wind-Battery Hybrid Systems in Türkiye's Electricity Market
This study evaluates the economic feasibility of wind-battery hybrid energy systems in Türkiye's electricity market, focusing on a 30 MW wind power plant and a 30 MWh lithium-ion battery storage system in Istanbul. The analysis covers four scenarios: participation in the day-ahead market only, battery dispatch based on state of charge, market price signal-controlled operation, and combined participation in both the day-ahead and ancillary services markets.
Key metrics including annual energy production, revenue projections, capital expenditures (CAPEX), operational expenditures (OPEX), net present value (NPV), internal rate of return (IRR), and payback period (PP) were calculated. The standalone wind power plant has a payback period of 6 years and an IRR of 17.62%.
When integrated with battery storage without ancillary services, the payback period extends to 8 years. Including ancillary services reduces the payback period back to 6 years with an IRR of 17.8%, indicating the necessity of ancillary services for BESS investment viability.
