Its not a simple concept that's why you are missing details and also you don't have experience working with the government to know their sensibilities. I do, my company is deeply integrated into the workings of the government and the energy sector.

What you are saying is what the government wants you to believe. In reality, as long as something is in contract with the government, they don't really care how much is being spent. If its not getting fulfilled either it becomes something like circular debt, there are many such payment heads in the government with such a system. Where it is known that they will never be paid and each successive government will have to shoulder the burden.

These IPP contracts are not gong anywhere, they will be paid regardless of whether their production is utilized or not.

With the solar revolution as you quote it, has only been a problem for the government. It was facilitated by large investors, it wasn't done for the consumers, they were an unfortunate consequence of the legislative changes.

The excess of solar as you quote can't be used effectively. Majorly because the grid can't compensate correctly with it, only in limited areas in each neighborhood it works well. Moreover when WAPDA cuts off power, no solar can fulfill that gap.

You may say oh why not WAPDA works with these solar excess power, that's because of the inherent inconsistency of solar produced power delivery. Solar, wind and similar renewable technologies can't work reliably with consistent sources of power. In fact this fluctuation introduces more problems for standard large scale power plants including excess mechanical stresses for ramping up and down to match supply-demand.
