Information with respect to how we operate the fuel cells in our Energy Servers is generally not publicly available, and given that, we want to provide some insight on the operating life cycle of our fuel cells. To that end, we have prepared this report to describe how we continuously track the performance of our fleet of solid oxide fuel cell (“SOFC”) power modules (“PMs”), how we define the economic life in the field of our PM’s through a median time to replacement (“MTTR”) metric and how we apply this framework to publicly available data.
