The Groton MEO issue is a technical issue that is unique to Groton.

This particular technology is not present at the other FCE plants, thus the issue doesn't exist anywhere else... according to Jason Few.

The nameplate for this Groton plant is 7.4MW of power. FCE is proposing going operational by September 30th with 6MW of reduced power and are confident their engineers can bring operations up to 7.4MW with upgrades over the next year.*

*Hmmm. So it is likely when FCE announced earlier 1 of the 2 Groton systems was operational it may have had out-put of 3.7MW and upon the 2nd system coming online and the introduction of the MEO component is when the power issues started. The MEO is a high temperature component.
**************
Groton is a SOFC system and the FCE patent below for MEO refers to MCFC.

"0009] A mixer/eductor/oxidizer (MEO) system has been introduced into molten carbonate fuel cells to address both the gas mixing and the pressure differential problems."

"0011] In particular, reduction in the fuel utilization negatively affects the overall system efficiency (power produced/fuel consumed)

Note: Yaphank 7.4MW plant became operational without any problems and now we know why Groton has been experiencing delays.
