Vintage Turbine Reliability

How to improve an old asset

Restoring Reliability into Vintage Gas Turbines

Grid Transformation has opened a gap for vintage gas turbines

The U.S. Department of Energy’s Grid Modernization Initiative is motivated by the need to transform “today’s legacy grid” into one meeting the needs of the 21st century. The Initiative has identified the following five key trends driving this transformation:

  1. Changing mix of generation
  2. Need for improved reliability and resilience
  3. Growing opportunity for customers to actively participate in markets
  4. Aging infrastructure and workforce
  5. The emergence of new interconnected electricity information and control systems.

These trends are affecting operators to rethink many things regarding their assets and operations. For example, the “Changing mix of generation”, the “Need for improved reliability and resilience” and “Aging Infrastructure…” are creating new market requirements to improve an operator’s ability to respond quickly to these new grid demands with available and reliable assets.

Many operators have vintage assets inside the fence line that can be started quickly but are often not reliable enough to be part of the solution for supporting tomorrow’s grid demand curve. The good news is that in many cases, these vintage machines need relatively modest updating to be made reliable and begin contributing to supporting the grid transformation and the operator’s revenue.

  • Decreasing Reliability
  • Increased Failures and Trips
  • Deterioration of Wiring and/or Grounds
  • Spurious Signals
  • Device/Unit Obsolescence
  • Lack of OEM Support
  • Increased Failures
  • Oil/Air Quality Issues
  • Mystery Trips
  • Increased Start Failures
  • Functionality Limitations

So, the question is what to do to make vintage machines more reliable?

TTS has produced a simple cost-benefit review for improving vintage unit reliability that was presented at the EPRI meeting in Arizona this Spring. The table provides you Budgetary Costs, System Benefits, Pros and Cons Evaluations, and a description of the Typical Upgrade Scope so you can better understand what technologies or actions make the best-valued outcome for your operations based on your specific drivers.

TTS engineers are available for consultation and/or a site visit if you would like to conduct an introductory assessment at no cost or obligation.
