CERTIFIED TURBINE POWER - CTP

Gas turbines play an increasingly important role in electric grid operations across the globe.  Providing grid support for increased solar and wind generation drives a growing need for small gas turbines. Refurbished gray-market units typically cost considerably less than a new gas turbine package but currently face a number of issues, including the lack of OEM warranty and questions regarding infringement of manufacturer’s intellectual property.

To address these issues, WattStock works hand-in-hand with a major gas turbine OEM to provide refurbished turbine generator packages with the same warranty and guarantees as a new unit, while preserving the cost advantages of refurbished units. 

The WattStock CTP program offers significant advantages over gray-market refurbished machines:

Lower project cost, increased output, lower heat rate, and improved reliability – delivered in six months or less and fully covered by a major manufacturers warranty and performance guarantees.  That’s the profile of a WattStock CTP aero-derivative gas turbine generator set refurbished leveraging state-of-the art OEM technology.
 

As the only packager approved by the partner OEM to refurbish their gas turbine generator sets, WattStock offers access to the full suite of OEM-engineered components, upgrades, digital solutions, and intellectual property that maximize payback and optimize life cycle value.  The solution may also improve project financing options and lower business interruption insurance premiums.

 
 


CTP – HOW IT WORKS

  • OEM provides WattStock a customer-selected refurbished gas turbine that is tailored for the intended operating application,
  • WattStock refurbishes the package in accordance with OEM guidelines and QC procedures using the latest OEM-engineered package components, modifications, and upgrades, 
  • OEM certifies each CTP; WattStock performs installation and commissioning under OEM supervision,
  • WattStock tests package to ensure performance guarantees, and OEM manages the warranty, and WattStock performs the warranty work.
