Lets get this straight. We have two companies A and B. We give company A a production subsidy of $1 million and company B a production subsidy of $1. Next we say that we will end all subsidies to create a level playing field. A level playing field is only created when the benefit received as a result of the subsidies is equalized. As a result of the initial subsidy, company A was able to invest and acquire $10 million in assets whereas company B was not able to make capital investments. For a level playing field, company A should be required to repay half of the capital value gained as a consequence of the subsidy. The repaid amount can then be given to company B, which will then have a subsidy benefit equal to company A. The taxpayer does not need to put any more money on the table and a level playing field is created.
As the largest shareholder in a small company in the energy business, I do not favor subsidies in general because larger companies tend to be better at buying government officials that small companies. I do think that government should undo the market distortion that it caused by providing subsidies in the first place.
