The ambitious German energy program predicts a rapid expansion of regenerative power generation. Caused by the fluctuating nature of regenerative forms of energy, the need for backup capacities in the form of similar-sized thermal power plants is clear. Consequently, components of gas and coal-fired power plants are exposed to sharp transients and a high number of cycles.

If German design regulations are observed, these operating requirements will lead to high levels of depletion of the integrated components. As a result, inspection and maintenance efforts will also increase. A reduction in the components’ life cycle can lead to a significant increase in costs.

To effectively deal with significantly higher requirements, the TÜV NORD Group has designed a strategy, COOP (Cycle Optimized Operation), that allows, on the one hand, a reduction of conservative assessments and, on the other hand, the development of new safety standards in the evaluation of the service life.
