And besides that, we still have — and on Page 7, some steps are being taken now, the first has been discussed, auction A minus 0 to bring part of the supply that did not appear to the concession renewal, the option of a contract of 2 years for 2,000 megawatts. Besides that, the adoption in experimental so-called tariff flags, this will allow us to have a greater number of consumers, especially the low-voltage consumers to be able to determine that consumption time where the tariffs will be lower, and we will be able to consume energy where the system has more expensive price, but we will have further so-called tariff flags, which will be applied as from 2014. But in 2013, we will already have this. And most of the companies, this will already be on the lightbulbs and we’ll use the most real generation costs as we can and applying these to the consumers.
And there was this exposure, involuntary exposure to the stock price. And naturally, this is involuntary exposure because the utility, it has contracted 100% that’s created if generators had offered 100% of credits. Since a few did not come clean, the quarter volume fell short of the estimate so this is why we have this BRL 37 million costs that is beyond the contracted volume below utility sales on [indiscernible] or equivalent to the stock price amounted to BRL 27 million. So you may perhaps demand perfect answers, this is important also made to generate [indiscernible] completely the hydro versatile rate is the plant always to generate what it has to, what was estimated. This is — it’s passed on to consumers. And this the hydrological risk, the so-called hydrological risk.
So we will start by Page 3, and in a very transparent world, give you some of the news that somehow or other have been prevented regarding this moment and recent events of the sector. Obviously, you know about the drop of the shares, generally speaking, of these companies which were affected by Provisionary [indiscernible] 679 [ph] and companies like ours which were not but the behavior of the stock market is the same.
So the expected 100 units of power and only 97 units of power is produced. So this, too, is the hydrology risk and those generators, you decided to run more plants at 32. We are certain that has its [indiscernible]. So this is the past transmissions. Now 3, now this is just the BRL 36 million, and it’s important to point out, out of the 4 items mentioned here is exactly, you use those on the interactions among the groups, and the governments and we are [indiscernible] under the association. It’s important to say that, [indiscernible] that. Well, we’re not [indiscernible] on this exposure. What happened has happened for the first time, but it will occur again for sure, or either the hydrology risks, which was not a built-on item, but had started to be as we converted that product volume integrated. Or the dispatch of thermal plants out of merit. So the 3 items which are a result of Decree 7,945 and in this quarter, we had the Decree, this would have — it would have been passed on to utilities. This would be [indiscernible] by city. Around BRL 100 million of this [indiscernible] to 260 will be shouldered by CVU.
Good morning. We have here our presentation of the fourth quarter and the close of 2012. I think this presentation is important to refer starting on Page 3. I assume that before we start the results, give you a quick review of the environment. I’ll give you an overview because I feel that sometimes, investors and analysts might have some questions about the last events of the sector and as we are the largest agent in this sector, I feel that we should clarify it from doubts, so that we can make more firm projections and positions and have a better idea of prospects.
As a result, the bottom chart summarizes the company growth. So we have the EBITDA — consolidated EBITDA growing at 7.5% a year, and we closed the year as the largest distribution company, market share [indiscernible] strength, and now we are the commercialization leader, 10% and we closed the year as the second biggest private generator, with 2.3% of market share.
