And the renewables get the highest price, which will always be higher than their production costs... It's designed to repay investment into non fossil fuel pow

  It is designed to extract credible bids from energy suppliers and minimize costs. The wider range of prices is the new thing, but the cheaper sources getting paid at the marginal price was always the intention. It stops people inflating their bid, which renewables could do if they wanted to queue jump, they'd just be risking that they are the most expensive renewable and they don't get picked, and get paid zero. It incentives the lowest cost producers (as long as it's regulated properly, see the Australian experience with gas cartels abusing the system).
