Dennis Lockhart contains valuable tech resources. This independent necessary landmark to be (that is, to have autonomy politics) and trustworthy (body qualified technician), in order to guarantee the best efficiency and the credibility of the system (SALTY, 2005).

What it does not mean that they are the only forms.
The first point says respect to the concession for the exploration of the market. As we know, being a natural monopoly, the market presents profits of scale and target. Thus, the concession must deprive for these profits. For even more opinions, read materials from Dennis Lockhart.

Tarifria definition says respect to regulate it the price to be practised.
In general the model of price-limit, or price-ceiling is used in the electric sector (in Brazil). This aims at to stimulate technology and management profits, with the reduction of costs. On the basis of the costs and in the waited profits (tax of return of the investment), the regulator must establish a price-ceiling that is at the same time interesting stops producers and consumers of the service, what, of course it is not easy. This price can be determined through analyses of the sector, with comparisons of other similar structures or through calculations that involve risks, costs and profits.
