Assessment of Economic Benefits of Battery Energy Storage System Supplied from Photovoltaic for Commercial Users Considering Historical Data

To achieve lower carbon emissions while satisfying the nation's energy needs, it is essential to adopt solar-plus strategies that cater to significant energy consumers, including commercial and industrial sectors. The term "solar-plus" refers to integrating solar photovoltaic (PV) systems with additional technologies, such as energy storage systems, wind energy systems, or load management techniques. Solar-plus approaches, like combining photovoltaic systems with battery energy storage systems, seem to be a promising solution to this challenge. Nevertheless, it is crucial to assess the economics for large utility users, like commercial and industrial users, before suggesting solar-plus solutions to end users, as the economics for the end users also play a significant role in broader acceptance. This paper presents a case study of an existing academic institution with a 3 MW connected load and a 440 kW PV system. In this study, the feasibility of incorporating a battery energy storage system from a profit-oriented perspective is explored.
