GE* Declared a “Last-Time-Buy” for Mark VI, But You Have Options to “Keep the Control” with GTC

Well, it’s official: General Electric has declared the “end-of-life” for the Mark VI platform by 2019. In their product life-cycle support notice for the control system, GE* announced a “last-time buy” for all Mark VI products through the OEM

At Gas Turbine Controls, however, we’re not increasing prices and we’re not limiting our Mark VI orders. We’re still supplying you with the same products and service we always have.

If you buy from GE*, though? Any orders for Mark VI products must be placed before December 31st, 2018 and can expect to be shipped by March 31st, 2019. These “last-time-buys,” as of January 2018, also now come with a 25% price increase for Mark VI modules due to the difficulty of sourcing those parts.

Is this surprising? Not really.

GE* had already ceased normal production of the Mark VI platform way back in 2009. Though they continued to receive orders to source Mark VI components, it was expected that this control system would eventually meet its end-of-life, like many other legacy systems before it.

Not ready to upgrade? GTC’s here to help.

Any plant operator knows that upgrades are expensive, even with migration efforts in place. When an OEM ends support for your system, though, it’s easy to feel pressured to upgrade earlier than necessary.
