u/Dismal-Risk-9608

evaluating whether to replace aging transformer infrastructure that is still functional but older. trying to build the business case around efficiency improvements and trying to find realistic numbers rather than optimistic manufacturer claims, someone at qxg electrical mentioned that the efficiency gains alone rarely close the business case on their own, it is usually the combination with reduced maintenance and failure risk that actually gets replacement approved

curious whether engineers who have done replacement programmes have seen efficiency improvements that were meaningful enough to justify replacement on efficiency grounds alone or whether the business case typically needs to include reliability and maintenance costs as well
