I think it is mainly that they change the price for exports less often than the price for imports. When the 15p/kWh for export was set, the price for import was quite a bit more expensive than today. So you could argue they benefitted us by not dropping it earlier. In the end obviously it's just a market, they take the price they can get. I doubt I really get much better from others.
