I work in this field too and know this first hand. Chinese power plants are known to be cheap & quick delivery but of unreliable quality. Most of the IPPs who buy them are in for short term and want quick return on their investment and sourcing from China meets their purpose. Now the operators have realised that buying chinese stuff is not going to work-out even on short terms.
Now here is my question to you: why is Reliance industries spending 8 BILLION on this? As we all know, 8 billion isn't a small sum. You don't piss away 8 billion dollars for unreliable stuff, because if it breaks, that's 8 billion flushed down the toilet. This isn't some Indian roti shop that can cut down on chicken and add more flour.
Why is Electricite de France taking the risk of Chinese equipment if it did not meet French standards?
