Ok I get your drift now - overtly that would be unfair unless proper compensation was agreed for the disposal or use of assets.
This has been done before and I cite the deregulation of British Gas with the hiving off of Transco to provide a common service with tariffs based on quantity, load and time of consumption, and a number of other factors. British Gas marketing and supply services into the system competed in an increasingl;y open market, albeit with one of their hands tied behind their backs for the first two years in each market segment in that they had to reduce market share.
I would think that a system could be devised for the RM to ensure the arrival of competition and allowing RM to compete.
What surprises me though is that there isnt a push to increase their business by opening up their services to other businesses overseas. If they are truly good at what they do, their consultancy business should be worth a bundle. For example on this, Shell took its internal refining and products tech services to the open market, not only in oil but now they cover mining, car building, racing, power plants and a host of other industries and in doing so I gather have generated revenues of over a billion a year and 20 million to their profit pile.
