Including Installed capacity for H2488,Kalivac based on data from: http://webcache.googleusercontent.com/search?q=cache:uHRkSGwARQMJ:https://www.ayen.com.tr/eng/Yatirimdetay.aspx?yatirim%3D31&client=safari&hl=en&gl=ch&strip=1&vwsrc=0 However, it seems that the plant is not active yet. Shouldn't the record mention this in some way?

Yes, the dataset shouldn't include plants not yet commissioned. This item was a sort of placeholder, waiting for the actual plant to be connected to the grid. I think the only solution would be delete this item and add it in the future.
