The customer is convinced after implementation of
SPPA-T3000 Unit Master Control
….
Our Operators which come from other CSP Plants
… confirmed that the automation level in all of them …
was very poor …
None of them had a Unit Master Control to drive the plant
(Load controller, pressure controller) neither Plant start-up/
shut down sequence.
… My level of satisfaction is very high with the works of
Siemens AG …. The people ... did it with a very high level of implication and
very high level of quality. It was incredible the change in the Plant after the
Siemens AG support. …
