This study evaluates the technical and economic feasibility of integrating Lithium Iron Phosphate (LFP) Battery Energy Storage Systems (BESS) into agrivoltaic photovoltaic (PV) arrays in the Vale do São Francisco.
Additionally, a recent project commissioned by a public sector client demonstrates the deployment of BESS frameworks designed to benefit local populations through energy credit compensation, specifically managing the injection schedule of stored energy into the local electrical distribution grid. The multi-objective dispatch strategy complies with ANEEL Resolution 1059/2023, leveraging Time-of-Use (TOU) tariff arbitrage while ensuring an uninterrupted power supply for drip irrigation pumping systems.
Energy modeling indicates that the proposed topology increases the self-consumption rate from 61% to 89%, mitigates daytime injection peaks by 34%, and guarantees 100% supply for nocturnal pump loads. Discounted cash flow analyses, incorporating tariff compensation benefits and water-use efficiency gains, demonstrate a simple payback period of 6 to 9 years and an Internal Rate of Return (IRR) of 14% to 19%. Ultimately, coupling BESS with agrivoltaic plants constitutes a robust solution for decarbonizing irrigated processes, optimizing distributed generation assets, and delivering socio-economic benefits to semi-arid regions.
