The highlights for this quarter in Slide 4 show the energy market when we compare it to the Q1 of 2020. In addition to negative impact in this quarter, it is important to remind you that preventive measures were announced only in March 2020. In this regard, in most of the Q3 last year, we still did not have the severe effects associated to the pandemic. Energy consumption until then grew at high rates because of the economic activity during this period. In the Southeast, it was going up under the impact of strong rains.
In the beginning of this year, different cities implemented restrictive measures as a result of the worsening of the conditions of the pandemic. In the Q1 of 2021, we carry over the COVID effect, which is being compared to a period of strong growth in most of the group's distributors. Under these effects, as indicated in the graph, the consumption in the commercial segment was the main problem in the quarter due to the limitation of operations of restaurants, business centers and also on-site classes in schools and universities and therefore the weak results in this class is not exclusive to the group Energies. It is also observed in the consolidated energy consumption in Brazil. In both cases, this class has recorded a decrease in all of the different regions, especially in the North and Center West.
The segments with highlights in the quarter were the industrial, especially in the construction related chain, residential because of the high temperatures and also the low basis in 2020 in the Southeast. Finally, a brief comment regarding the market according to the different distributors. The highest increases were observed in the Southeast Minas Gerais and Fribourgou. They were leveraged by residential with a combination of low basis in 2020 and high temperatures in 2021 and also in industry, especially mining, cement production, metal and paper in these regions. On the other hand, Rondonia and Acre decreased consumption in the quarter as a result of the strictening of the restrictions associated to the pandemic.
We also had strong rains, which led to a state of public calamity in different cities. In Slide 6, I present the overall losses of the group. In the 12 month curve, we saw 13.77%. Basically, it was stable when compared to the December indicator. There was a trend towards improvement in the loss curves when we look at the month of September, which was 13.82%.
The accrued performance in the months of July September was strongly affected by the first wave of the pandemic. The months of March and I'm sorry, of December March still carry these effects, but with improvements in the loss curves as a result of continued action to fight losses with investments in new technologies for the detection of fraud, inspection methods and protection of the measurement network among others. I would like to highlight that the Rundonia and Acre concession remain with an increasing trajectory of losses. This is consistent. And then in Slide 7, I highlight that 10 of our 11 distributors continued within the regulatory limitations in terms of the DAC quality indicator in this quarter.
The star of the day were Energiza, Borborema and Tocantins, because they presented their historical minimum. Regarding the fact indicators, all of our 11 distributors were below their regulatory limits with a highlight to NovaFrip, Google, Barema, Mato Grosso and ACI, which also had their historical minimum in this Q1. Even in a critical scenario of the pandemic, we maintain our productivity and our results. With this, we have obtained important positions in NAL's annual ranking, which take into account DEC and FEC that was published on March 15. Within this category above 400,000 consumer, we classify 7 distributors among the 12 best Regarding the category below 400,000 consumers, EPO and ENF were classified among the 8 best.
A reason for us to be proud at Energies. Now, moving on to the next slide. This is our last in the operational highlights slide. We had a consolidated rate for March 2021 accumulated in 12 months of CAD 96.47 when compared to the total in the same period, above 96.41 percent presented in March 2020. This positive performance is still more relevant since we are comparing this indicator, which captures in 2021, the whole pandemic period, including the last 12 months with the prior indicator, which is considered a pre pandemic indicator.
This slide now includes expenses for the provision of double liquidation credit, which presented a reversal of $3,300,000 this quarter. We had a reversion of $96,500,000 resulting from the session of receivable titles in some of our controlled units, where the majority was already provisioned for IFI, I'm sorry, DC. In this quarter, the amount would have been BRL93.2 million, representing an improvement of 20% when compared to the Q1 of 2020, whose provision amount was BRL126.1 million. At the end of this slide, I turn over to Mauricio Botele. He's going to talk about the financial highlights in this quarter.
Well, thank you very much, Ricardo. Good afternoon, ladies and gentlemen. We're now going to move on to slide number 9. We're going to talk about PMSO. In the Q1 of 2021, the PMSO totaled BRL620 1,000,000, a reduction of BRL45 1,000,000 when compared to the Q1 of 2020.
The 6 companies that contributed for this reduction when compared to the Q1 were Energizer Hondonia, Mato Grosso do Sul, Akeri, Minas Gerais, Paraiba and Totentes. The overall amount of this reduction was BRL 55.8 million or 15% when compared to the Q1 of 2020. Eneljiza Handonia contributed with 53% of this reduction and Mato Grosso with 17%. It's important to highlight that we have presented a reduction in all of the items in this indicator. Expenses with personnel had an indication with labor law payments and benefits as a result of the migration of health.
We also had a reduction in the purchase of materials and in hiring outsourced services. Rondonia had a reduction of expenses with preventive maintenance and deadline maintenance as a result of the internationalization of labor for services such as cleaning areas and pruning. The line of other expenses had a reduction of RMB21.3 million. We're now going to move on to Slide 10. In Slide 10, we will talk about the EBITDA in the Q1, which presented an increase of 54% or BRL458 1,000,000 when compared to the Q1 of 2020.
The range in the quarter of the adjusted EBITDA used for the calculation of covenants, which takes into account the delinquency increases, were 53.3%. This performance is explained especially by the increment of Parcel B of the in the case of Topengento, Hondona and Aki and Verborema. And also because the market grew in some distributors. In addition to that, we had a reduction of PMSO costs and the other 6 distributors had an average growth of only 2%, in other words, well below the IPCA in this period. The EBITDA without non recurring effects and noncash events, had an increase of 33% quarter over quarter.
And then in the next slide, we compare the Antenna in the last 12 months, quarter by quarter, against the PMSO expenses. As you can see in this 12 month graph, it removes the volatility and seasonality from one quarter to the other, and we can see a constant improvement in operating expenses of MSO, which reduced BRL383 million on an annual basis, which helped with the evolution of BRL944 1,000,000 in the EBITDA reaching BRL4.8 billion. PMSO represented 75.9 percent of the EBITDA and is now 52.9%. Our guidance for 2020 when compared to the PMSO reduction between 5% 7% was over time in 2020 and we continue presenting this year still a reduction of costs due to the efforts maintained by our management. We are still positioned among the largest PMSO in the distribution sector in this country this year.
In the next slide, we compare the performance of the EBITDA against the regulatory EBITDA and we'd like to highlight the last two acquisitions, Acli and Hondona. Also, we are already operating with a performance of 40 3% when compared to the regulatory EBITDA. In the case of Hondona, which left from a situation where the EBITDA was highly negative BRL200 1,000,000, we are now moving on to positive. Aker, we went from a situation where it was much lower than the regulatory Etcetera. And today, we have gone above it.
Of course, this evolution is reflected on the net profit of these companies. Rondonia already has a net profit for 2 consecutive quarters and Acri for 3 consecutive quarters. In the next slide, we're going to talk about our net profit. In the quarter, we had BRL873 1,000,000 when compared to BRL 592 1,000,000 last year. We once again can see the effect of subscription bonuses in addition to other nonrecurring and noncash events.
The growth remains relevant. Profit is reported at BRL408 1,000,000, representing an increase of 2 56 percent when compared to the same period last year. In other words, additional BRL294 1,000,000. In Slide 14, we're going to talk about our indebtedness. We have a total of BRL14.2 billion, a growth of BRL647 1,000,000 compared to the debt in December 2020.
Until March this year, we had 15 operations, including rolling, strengthening, long term loans, which totaled BRL1.63 billion. We have concluded the quarter with a robust position with a robust cash position of BRL5.7 billion. The average term of the gross debt is 4 years and the average cost is 5.15% per year when compared to 4.54% in December 2020. Our main indexator is CDI with 66.8% of the debt. In March, the annual adjusted EBITDA was 3x when compared to 3.1 times in December 2021.
Our limitation of covenants for this indicator is 4 times. In other words, we are at a very comfortable situation. And then in the next slide, we're going to talk a little bit about our investments. In this period, in this quarter, we had BRL698 1,000,000, a minor reduction of 2 point 3% when compared to BRL714 1,000,000 in the Q1. This reduction occurred for special obligations and non electric assets.
Taking into account the electric assets, there was an increase of investments of 7.5 percent or BRL42 million of the total invested in this period, 80.3 percent were for the distributors and 18.4% for the transmitters that are under construction. We have 13 ongoing projects to have been already inaugurated this quarter with investments of BRL24 1,000,000 and a capacity of 6 point 2 MWP. The investments of the other 13 projects are in the order of approximately BRL150 1,000,000. In 2021, we will have record investments. We have already announced it.
We did so in the beginning of the year, and we we'll invest BRL3.8 million in the distributors. We will have BRL2.8 billion invested in transmission. And in Hondonia, we have expected investments of BRL747 1,000,000, BRL314 1,000,000 in electric assets and BRL410 1,000,000 in special obligations, including the interconnection of the 9 isolated systems in the second half of the year. And we have the Mato Grosso in Energia de Mato Grosso and Mato Grosso do Sul together totaling BRL1 1,000,000,000. And then in the next slide, we're going to talk about transmission.
We have 5 enterprises. They represent 258 million of permitted annual revenue in for the 2021 cycle, we have signed a concession agreement for Enigis de Venezuela Amazonas with a payment of BRL239 1,000,000 to Amazonas Generation regarding the acquisition of the assets existing in this concession. We also started the receipt of 30% of the total RAP. In terms of projects, we expect an average anticipation of 12 to 18 months, including the re vitalization of the existing assets. I would also like to mention that in regards to our transmission project in Tocanstin, we are now discussing long term funding with BASA and BNDES in the amount of BRL500 million, representing 75 percent of the projected CapEx.
We want to continue growing the transmission segment and are looking at assets that make sense to us in synergies with the current assets of the group. I think you offer your attention for another important meeting and we are now open for Q and A. We're now going to start our Q and A. Please wait while we collect questions. Our first question is from Carolina Cardeso, Chedesuisi.
Good afternoon. Thank you for the call. I have two questions, please. The first question is regarding PMSO, which was presented this quarter. You have had since last year part of these amounts and this was affected by COVID.
You also mentioned some other effects such as the internalization of labor, but I wanted to have an idea of the level of costs that we will be seeing this year. Can you tell us a little bit about that? The second question is about the auction of the Amapa distributor. I would like to know about your interest and the challenges that you see regarding this asset. Thank you very much.
Well, I'm going to share the answer with who is here with me. One of our concerns here right now is exactly this increase of commodities in general. This may have an impact on the costs of supply and that affects services as well since the purchase of materials is also included. It is difficult for us to give a guidance right now because everything is very volatile. We are experiencing some increments of unit costs and that also has an impact on CapEx.
We have delayed some purchases to see if prices stabilize. I have tried to add some things, But basically, this is it Mauricio. We're working hard. We're now trying to buy what is really necessary because we have a lot of pressure. There is an inflationary pressure.
It is difficult. We're going through a very volatile moment. This is a challenge. We're trying to optimize our purchase process. Have I answered your question, Carolina?
Regarding costs, yes. Could you comment the CAA process for the Amapa distributor? Are you interested or not? Do you see any special challenge there? I would say the following.
In general, there are a lot of opportunities in the electric sector as a general rule. Of course, it's a complex asset. It is small. It does have problems. But we should always look at it closely.
Perhaps there is not a lot of synergies to begin with according to our current businesses. Okay. Thank you very much. Our next question is from Marcelo Sa, Itau. Marcelo, please proceed.
Thank you for the call. I have a few questions. I think I have already commented about it. It's regarding IGT. The other question is regarding CG29, which deal with loss methodology.
Do you think that the changes you are discussing will have a substantial impact on the regulatory losses you have today? And the other question is regarding the operational cost methodology. In the beginning, we had some counterintuitive results. There were some errors in calculations and the parameters that were defined. I would like to know if this is evolving and if you could comment on it.
And I also wanted to know about the efficiency ranking and what the adjusted methodology is? Thank you, Marcelo. We're going to divide the answer and I will talk about the first question regarding the opportunities. We are carefully looking at all of the transmission assets. Talun and the transmitter.
It's very interesting. We are also going to analyze generation. I will turn over to Alexandre, so he can answer the other items. Good afternoon, Marcello. Good afternoon, everyone.
Regarding Public Consultation 29 and the loss calculations and recoverable. We discussed with NOL to our contributions and I believe that this public consultation will see results in the near future. In terms of your question of what we see, we are a company, perhaps with the exception of Energies de Hondona, which was recently purchased, our companies, as demonstrated in the presentation by Ricardo, have losses at an efficient level. What we believe right now is that the signal for these companies who have an efficient level of losses tends to improve. This is what we have discussed with ANAL.
We believe that there will be changes in the signal regarding CP62. We are also discussing with NAL. These discussions have been very good. I believe that this methodology will be different from what was proposed. There are improvements to be made.
Contributions are regarding the salary index and I believe that a lot of the contributions we have shared accepted. It is a public consultation for second half of the year, and I think we will close this deal. There was a specific aspect in this public consultation. It had to do with the impact of the labor lawsuit. Do you think that it will be confirmed?
Well, the contribution was very robust, not only for Energies, but Braggi and different companies in the sector. This contribution was taken into account by the regulation I'm sorry, by the regulator, and we asked for a differential treatment. But we have had an improvement of the information base. In our specific case, the contribution of the salary index was robust. We also have other aspects to be taken into account.
There are numerous concessions. If we consider all of them, we can see that there is a lot of opportunity for an improvement of the trend methodology. We believe that in the Q2, we will conclude these negotiations. The contributions have been very good and it will take us a while or it will take the regulator a while to accommodate. This new methodology would only have an impact on the tariff adjustments after 2022?
Yes, correct. Okay, great. Thank you. We have a question via webcast from Fernando Zampaio, Brazil Capital. What is your opinion about the PMSO management for 2021 since the expectation was to grow above inflation because of the resumption of activities?
Good afternoon, Fernando. I think that this is very similar to what we have already discussed with Carolina. It's difficult to give a guidance right now because of the increase in the price of commodities that may have an impact on the causes of supplies and services. We're trying to keep it below inflation rates. We have had a reduction in this Q1 and this is what we are hoping for looking into the future.
Our next question via webcast is from Sergio Araujo. I would like the company to explain what factors have led to the improvement in the results of Energiza Services results. Energies de Solucines, the solutions company, has had stable profits when compared from 1 year to the other. The EBITDA of Energies and Solar Science grew 6.4 percent, median to 6.7%. It wasn't that expressive.
Icard, would you like to complement my answer? You have answered it, Mauricio. We have evolved in some lines. We had improvements in contribution margin, which is an important aspect in lines that when we take into account the different services provided by Energies de Solucais, we have had some improvements in most of the lines in terms of more contributions. The result was small, relatively small, but it was superior than what was recorded last year.
We also have other contributions regarding the assets numbers that were indicated in the results for the Q1, Robert, who is joining our team, will expand the results of all of these divisions regarding services, including distributed generation and also Energiza Comercien El Zadora and other businesses that may be incorporated in the portfolio of Energiza Services. Our next question is from Andre Sampaio Santander. Mr. Andre, please proceed. Good afternoon, everyone.
I wanted to ask one question regarding the comments you made to participate in generation of 3CE. I wanted to hear from you, if that indicates that you are considering more aggressive movements in the world of generation and perhaps have a more relevant position as you had in the past? And also, if you're willing to analyze the M and A market for renewables so that you can go back to the sector? We always have to look for opportunities in the electric sector. It depends on the project itself in the case of the 3C and generation.
So we will retransform There is a new vision on the assets. We have some projects in the pipeline. We have the wind farm in Subradenga, which is being developed. We have price conditions. These are opportunities.
We have a higher percentage in the free market. But it will allow us to have a more aggressive opportunity in this segment. But in fact, these are activities that are very interesting within the strategic objectives of Energizer. Well, with that, we could complement the answer by saying the following. These projects are strategic there is a price scenario that is more adequate.
We can see the prices growing. These projects have a window for the use of the Tuzi discount. From now on, renewable energy projects will no longer have this discount. We have 2 solar plants. We have 2 wind projects.
We are looking at prices, variation and including everything in this so called universe with a possibility of commercializing that will be an alternative as well as other opportunities for privatization. We are actively evaluating all of the opportunities. I now turn over to Mr. Mauricio Motelio for his final considerations. Mr.
Mauricio, please make your final considerations. I thank you all for your presence here at Energizer's conference call. I believe that we are going in the right track to contain expenses, looking at efficiency and we're very optimistic with the resumption of our economy this year. We also have a good cycle of commodities knocking at our door And that may be good for the regions where Energiza operates in the North and Center West. I thank you all for your attention.
