Multiple requests from the same IP address are counted as one view. This paper assesses the profitability of battery storage systems (BSS) by focusing on the internal rate of return (IRR) as a profitability measure which offers advantages over other frequently used measures, most notably the net present value (NPV).
What is internal rate of return (IRR)?
Internal Rate of Return (IRR) This paper is based on the IRR as a key economic metric for assessing the profitability of investment projects.
Should internal rate of return (IRR) be used to assess profitability?
We argue in favour of the internal rate of return (IRR) as a preferred method to assess profitability given the advantages over the popular net present value (NPV) and many other frequently used profitability measures.
