Thank you, operator. I'd like to welcome everyone, and thank you for being here, for attending this presentation of the results of the first quarter of 2024. Joining me are our CFO and Investor Relations Director, Mauricio Botelho, the Vice President of Regulation and Institutional Relations, Fernando Maia, the Vice President of Energy Solutions and Leader of (re)energisa, Roberta Godoi, the CEO of ES Gás, Fábio Bertollo, and also our investor relations team. Before I begin, I'd like to kindly ask you to pay attention to this slide before you make any investment decisions in the company. Before we start, I'd like to discuss the results of the first quarter of 2024. Before, I'd like to highlight the milestone of the 10th anniversary of the acquisition of Grupo Rede, one of the most successful operations in the Brazilian electrical sector.
To celebrate this occasion, we have prepared a special message of this as part of this earnings call, so that you can celebrate with us. On April 11, 2014, Energisa assumed indirect majority ownership of Rede Energia SA, and consequently, to control the electric power distributors in Mato Grosso, Mato Grosso do Sul, and all the southern and southeastern regions. In addition to a power generator and an electric service provider. The turnaround of Grupo Rede was also a turning point for us, as we assumed the position of the fifth-largest energy distribution group in the country. We went from having five to nine concessions, more than doubling the number of customers.
The responsible capital allocation, in line with the continuous operational improvement and meeting market growth demands, has yielded positive results for us in the last decade, as you can see on this, the numbers of this slide. We were able to multiply invested capital by 6.7x and achieved a nominal return rate of 36%. In terms of remuneration base, we grew by more than 100% between the third and the fifth tariff review cycles, and today, our EBITDA of the four concessionaires represent more than 60% of the consolidated adjusted EBITDA of the group. The quality indicators also demonstrate our efficient operational management. Experience that we acquired during the privatization process of the sector in the 1990s. For example, at Energisa Tocantins, we had a noticeable improvement in quality indicators, DEC and FEC, which were almost halved.
The history of Grupo Rede is another case of success that highlights the best practices in terms of public service distribution, with an efficient, responsible, and prudent expansion of the Energisa group. Now, to begin the presentation of the results of the group for the first quarter of 2024, I'd like to highlight that we had the largest variation in EBITDA between quarters in recent years and reached BRL 2.2 billion in adjusted recurrent EBITDA, which excludes the VNR from Electric Power Distribution segment, non-recurring effects, and includes a regulatory EBITDA from the Transmission segment. Significant part of this result, and a profit of BRL 800 million of the period, was driven by the energy market that grew by 12%, including non-invoiced amounts, compared to the same period in 2023, marking the highest quarterly growth in the last 21 years.
As you can realize, Brazil is currently experiencing the effects of El Niño and some atmospheric blockages in the Midwest region, leading to successive heat waves in our concessions. And in 2023, we experienced milder weather conditions. Those extreme weather events have been a major concern for everybody, requiring immediate action from individuals, business, and authorities. And I take the opportunity to express my condolences and my solidarity with the victims of the largest climate catastrophe in Rio Grande do Sul, and we offer support to the energy concessionaires in the state, the concessionaires of that state, that they can restore the essential services as soon as possible. We'll address now the market behavior in more detail later in this presentation. The first quarter of 2024 was also marked by two significant events.
First of them was the conclusion of the company's primary public offering of shares, which brought in BRL 500 m illion to the cash reserves, contributing to the improvement in leverage and providing flexibility for potential future acquisition, movements, and investments in the segments of our portfolio. We expanded our Transmission portfolio through the acquisition of Lot 12 in the auction held March of this year. Energisa Maranhão Transmissora de Energia is the thirteenth concession of the Energisa group, and has an annual permitted revenue, RAP, of BRL 112.5 million. The DG segment, we continue to expand our portfolio. We now have 367 MWp of installed capacity, plus 94 plants. In ES Gás, we grew our customer base by over 8% and reached 524% of [revenue].
We're very pleased with the financial and operational performance of the group this quarter, and we are confident that the strategy of growth, quality, and diversification will continue to contribute to significant increases in our earnings per share. With that being said, I'll now give the floor to Mauricio Botelho, CFO and Investor Relations Director, to continue with the presentation of the results for the first quarter of 2024. Mauricio?
Thank you, Ricardo, for the presentation, the initial presentation. I will approach some aspects of the presentation. Before everything, good afternoon, everyone. I thank you for attending this earnings call of the quarterly results of Energisa. Even greater focus to the financial results of the quarter, as Ricardo has already mentioned. We've had an exceptional performance this quarter. The current EBITDA rose by 45.8% and reached nearly BRL 2.3 billion in the quarter. The highlight was the energy Distribution segment, which contributed to with BRL 2.9 billion in growth margin, presenting an increase of BRL 650 million compared to the first quarter of 2023. Contributing to this performance, also the tariff reviews of 2023 and the good performance of sales of energy in this quarter, as Ricardo already mentioned.
I'd like to draw your attention to some non-recurring or non-cash effects we're considering from this quarter onwards, the purpose of adjusting the result. First is the provision of profit sharing results, the PLR, BRL 61.3 million positive impact in the consolidated PMSO, to the adjustment of recognition on a monthly basis, rather than in the last quarter of the year, previous years. The second is the provision for over-contracting at Energisa Acre. BRL 8.9 million effect for the quarter in the line of assets and liabilities of the AC. Due to this, the adjustment of the provision practice on a monthly basis, now we're estimating the impact of that for 2024. These two changes in the presentation aim to bring less volatility between quarterly results, especially in the fourth quarter.
Another important item was the reversal of contingencies at the Energisa Rondônia. BRL 141.4 million as a positive effect. It was a reversal of effects that were accounted during the acquisition of Rondônia in the last quarter of 2018. This non-cash reversal occurred only in the consolidated result, did not contribute to the individual result of the distributor. Another effect here is the mark-to-market of Energisa Comercializadora. During the quarter, the price curve, which marks the portfolio of Energisa Comercializadora, showed some atypical volatility. The reference prices for 2024, 2025, and 2026, for example, right by 27%, 33%, 25%, and 26%.
Despite the average, PLD remained at the floor of 61.14 MWh during the same period. As a consequence, we had an impact to the mark-to-market of the portfolio of BRL 120 million for the quarter, which was a non-cash effect. But I'd like to highlight here that in April, this negative effect was largely reversed in the adjustment of future prices due to a positive hydrological outlook at the end of the rainy season, bringing the volumes down to 74.9% in the SIN for April 28. And the projection of the PLD remains below BRL 80 for 2024. Another effect here that is another non-cash effect, the result from mark-to-market of call options of shares of the subsidiary in here.
Since that impacts only the net income, because it is recorded in the financial reserve. All those effects will be addressed along this presentation. Now, let's talk about the PMSO slide. The consolidated PMSO with an increase of 19.5% compared to the quarters. Discounting the non-recurring effects that I have already mentioned, the PLR goes to a recurrent PMSO base of BRL 828 million, representing not 19%, but 11.2% comparing to the same period in 2023. It's worth mentioning that in terms of narrative basis in this Distribution segment, that represents 87% of the PMSO. The MSO increased of 5.3% in the quarter when the PLR is excluded, a little above inflation.
I can also highlight that the PMSO is linked to ES Gás, that started to be part of the portfolio of Energisa from the second quarter of 2023, and the segment of distributed generation. Many clients connected between Q1 2023 and Q1 2024, which naturally brings up growth for the operational costs. Going back to the other slide, in terms of net profit, we had a result of BRL 800 million, almost BRL 500 million increase compared to 2023. This result is explained by a superior performance of the Distribution sector and inflation expenses were lower comparing 2023 to 2024. The net profit of the consolidated before the adjustment was BRL 902 million or 125% superior to the first semester of 2024 quarter of 2023.
Now talking about investments, investment volume was lower 1.5% in compared to 2023. Let's bear in mind that some concessions went tariff review in 2023 due to slowdown in growth base in the Distribution sector, and also the projects of Transmission, distributed generation segments that were accelerated in 2023. We, we remain committed to achieve the BRL 6 billion raised investment that planned for the 2023, that was already disclosed to the market, at a level that's very close to last year. Next slide, we're going to talk about indebtedness. The Energisa group closed the quarter with a net debt adjusted EBITDA leverage indicator. The governance effects are at 0.6 x of the lowest level recorded in the, the last 12 months.
As Ricardo already mentioned in his presentation, we had a cash reinforcement during the primary follow on, which added BRL 2.5 billion to the cash reserves of the group. This operation reinforces our financial discipline, enabling us to maintain a strong level of investments and create room for potential inorganic investment. This is the summary of the consolidated. Now we're going to go in the breakdown of the segment, and let me initiate with the electric power Distribution segment. This slide, as I already mentioned, we had a great and notable growth of the recurrent EBITDA, which increased for 40.5% compared to the previous quarter, which BRL 1.97 billion, and the recurrent net income grew almost 70% between periods, and surpassed the milestone of BRL 1 billion per quarter.
Besides that, the market growth, coupled with many successful tariff reviews, were essential factors for the improvement in the financials of the Distribution segment. This next slide, we have the dynamics of the elevation of the market that advanced by 11.9% before non-invoiced amounts in the first quarter of 2024. With the largest variation in 21 years, as shown in this slide, you can see the evolution on the slide. So using the same metric, Brazil increased by 8.6%, the highest rate in 14 years since 2011. So I'd like to highlight the difference in the residential segment of Energisa, compared to the country, to Brazil, as a whole. Segment advanced by 17.6% in Energisa, while in Brazil, just 12%. All distribution companies showed growth, highlighting Mato Grosso, the South, Southeastern region.
Mato Grosso do Sul at a record rate, Paraíba, the highest rate in 11 years. These distributors account for almost 70% of the increment. This next slide, you see a chart here, an image here, that shows the effects of intense climatic effects. So with a 22% higher need for cooling compared to 2023, due to the heatwaves and the dynamics of the food chain. In 2023, we had an opposite climate scenario, as shown in the image. So next slide, let's talk about DEC, FEC. On November 22, ANEEL approved the continuity of electric power supply Distribution segment, and also the document 442 established the achievement of a minimum percentage of 80% of sets within the regulatory boundaries of DEC and FEC from 2023 to 2026.
To reach the 80% target by 2026, some annual goals were established for each concessionaire in Brazil, considering gradual increase in the minimum percentage of sets within the regulatory limits. This slide references of what realized in 2023. You can notice that we are within the goals, according to the targets established by ANEEL for 2023. Some of them are already meeting 80% established official document. On this next slide, we're going to talk a little about loss of energy. The first quarter, we had a total loss index of 12.74%, representing 0.12 [AP] higher than recorded in December 2023. This variation is attributed to the effects of the high temperature recorded in the concessions, as we said before, and also the capture of the effect of the non-invoiced energy.
In this slide, we're going to talk a little about default. It's another highlight. This sector reduced by BRL 7.3 billion in comparison to 2023, even with an increase of 16% in revenue between those periods. It goes up to BRL 1 billion. There's a small percentage increase in the category, which was much lower than the increase in revenue for the quarter. I highlight the government program, Desenrola Brasil, extended into 2024, continues to contribute to improvement of credit for individual people with low income, through the settlement of debts. In the first quarter of 2024, 31,000 clients settled their debts after negotiation, contributing to the reversal of BRL 19.5 million in the credit loss provision. The positive impact of low-income customers has been a priority since last year. Energisa has leadership among public service concessions in this program, Desenrola.
For now, I finished the Distribution segment. Now let's move on to the Gas Distribution segment. ES Gás ended the first quarter of 2024 with a total of 81,707 consumer units, an increase of 8.4% compared to the previous year, expanding 543 km of gas network. And the investments continue to be intensive in the concession, aiming to achieve the planned BRL 100 million invested for 2024. In terms of volume distributed in the quarter, the total volume was 156.5 million cubic meters, impacted by the reduction of the thermoelectric segment, due to the end of some emergency thermal power plants. Gas segment was negatively impacted by some incentives granted during 2022 and 2023 to some other liquid fuels, which were not extended to gas.
ES Gás has been working with the whole natural gas chain in Espírito Santo, proposing some measures to promote the use of natural gas through the Mais Gás movement that is going to be launched by the state government. Now, moving on to the next slide, we're going to talk about Transmission. I highlight here that on March 28th, there is a Lot 12 in the ANEEL auction, with an annual permitted revenue of BRL 112.1 million. The lot is located between Maranhão and Piauí, and involves the construction of a transmission line that will expand the basic network, the northern area of the Northeast region, for the Transmission of renewable energy already contracted in the region, raising margins for connecting new generation projects and meeting the local demand.
Another highlight in the segment was the choice of the Transmission functions certificate for Tocantins II by. As it was five months ahead of the regulatory deadline of September 2024. The project costs within the expected range, demonstrating our commitment to resource management and on time. In the first quarter of 2023, we highlight the increase of regulatory EBITDA, especially due to the readjustment of the RAP 99%, and the commissioning of some new facilities in Amazonas, and the reinforcement of Pará 2. After the tariff adjustment, the total RAP for 2024 was BRL 891.2 million, not including approximately BRL 40 million in optical fiber revenue from companies that come from Gemini. It's worth noting that in the last May 3rd, the release certificate for energization of Tocantins II, as I have already mentioned, five months ahead of the deadline.
We continue to work intensively to complete the assets that are being built, always aiming to advance the operation and then improving the return of our—Now, let's discuss the results of the Energisa. The recurrent EBITDA of Energisa, considering the sum of individual results from generation, trading, and value-added services, excluding the mark-to-market effect on the trading segment, increased BRL 70 million compared to 2023, reaching a total of BRL 78.4 million. I highlight the distributed generation, added 38 million of EBITDA during the period, and was acquired with BRL 20.3 million. We concluded the full capacity of 363 MWp in 93 plants. Our subscription product for solar energy has been gaining more subscribers. We grew our customer base by over 8.47%, closing the period with about a thousand and 42 affiliated customers.
With that, I conclude my presentation of the quarter, and I open the floor for the Q&A. Operator, please.

Operator, I think that we...
Our earnings results, it was very, very clear, and I see that we have no questions, or maybe we have one. Okay, we are receiving one here. Let's wait a little. I'd like to ask you just one more minute for us to collect the questions.
[Foreign language]
Our first question comes from Luciano Costa, journalist. We're now opening your audio so that you can ask your question live.
[Foreign language]
Luciano, you may proceed, please.
[Foreign language]
Good afternoon, everyone. Thanks for the call and Q&A. [Foreign language] You have signaled that renovation of the concession will be talked about. The secretary has said that some requirements of backfit will be different. So do you think that it may increase investments in concession area? Or what can we expect on this new regulatory package for concessions? Thank you.
So give the floor to Fernando Maia for him to reply.
Luciano. Yes, indeed, we've been following this, also talking to this department regarding the concessions. So that's the news that we had. They are ending, like, finishing the creation of a decree that will be sent to the Casa Civil. So he talked to us about this, these new requirements.
So it will be a little more strict, especially regarding quality, that will also require more investments. We understand, the department also understand, corroborated by the Audit Court, is that the regulatory mark, they allow this prorogation and might be seeking, looking for the public interest. That is the way for the concession prorogation. So this public interest passes through enabling the anticipation, the advancement of this prorogation, because it gives certainty to the concessions and gives to the customers the advantage of having a stricter regulatory, seeking for improvement in the quality service, the quality of the services, and in this preparation of the distributors to face those new weather conditions. [Foreign language]
Thank you.
[Foreign language] So concessions will be advanced, even those that are due a little later.
Thank you.
[Foreign language]
I'd like to remind you, in order to ask questions-
[Foreign language]
Look for the Q&A icon at the bottom of your screen. Following your protocol, your names will be announced, and then you'll be able to ask your question live. Our next question comes from Andre Sampaio, sell-side analyst of the Santander Bank. Andre, we're now opening your audio so that you can ask your question.
[Foreign language]
Andre, please, you may proceed.
[Foreign language] Good afternoon. Got it now on the microphone. Super quickly, I'd like to give you an update regarding the regularization of ES Gás. Regulation of ES Gás, just for us to understand, if everything going by the book? [Foreign language]
[Foreign language] Good afternoon, Andre. The regulatory process is according to what was predicted by the contract. We don't see any delay. We, we are following the schedule. We accepted our investment plan. No, no, no points of attention that should worry us here.
[Foreign language] Thank you.
[Foreign language]
Our next question, Daniel Travitzky, sell-side analyst of Safra Bank. Daniel, we are now opening your audio so that you can ask your question. Daniel, you may proceed, please.
[Foreign language] Good afternoon, everyone. Thanks for the opportunity. I have two questions, actually. First is about the MP 1.242, just to understand the perspective of the company regarding this provisional measure, that is some tariff reduction, the participation of CDE. So I'd like to hear from you, how you see that, backed by approval and timing. And the second question is that I'd like to comment on subventions line that you highlighted in the release.... It was a significant amount this quarter. Can you help us understand how this account works? What drives the increase in this line? It would help us a lot. Thank you.
Fernando, can you take this one, the first one?
Regarding MP 1212, the Provisional Measure, we have good expectations. Everything that comes for reducing tariffs is good for our customers, so it's good for us as well. Part of the MP talks about the utilization of part of that fund, CGPAL, that is like the application of resources in the Legal Amazon. It, of course, depends on the minister, on the secretary, might benefit and attenuate highest adjustments in the North region. And this second part is the anticipation of the resources, CDE, that needs to be approached wisely. The MP is due 120 days. Regardless of the discussion in this, in the Congress, it has legal effects. All those operations can begin within the spirit to deliver the results that... That's their purpose.
Daniel, regarding the subvention, the RI team will send you some details. It is connected to CDE, right? Okay, Mauricio.
Thank you. I'd like to remind you that to ask a question, you should click the Q&A icon at the bottom of your screen.
