Thank you, operator. Good morning, everybody.
I'd like to thank everybody for being here at this conference call for the earnings release on the fourth quarter of 2022. I am Eduardo Capelastegui, CEO of Neoenergia. Once again, we're very proud of what we are sharing with you today. With me, we have Solange Ribeiro, Director and VP of Regulations, Institutional Relations and Sustainability, Leonardo Gadelha, CFO, Juliano de Souza, Executive Director of Asset Control & Planning, Sérgio Machado, Distribution Executive Director, and Renato Rocha, our Investors Relations Director. I will conduct a brief presentation going through the key information on the period. Then Leonardo will present you with the results. Then we're gonna have questions and answers, followed by the closing remarks. Starting with slide number four.
Our EBITDA was BRL 9.7 billion, presenting a growth of 32% over the year, reaching success with tariff adjustments and project progress, such as Termopernambuco and the investments and constructions both in transmission lines and renewable energy. Net profit in 2022 reached BRL 4.7 billion in 2022, 20% above 2021. A result of our execution capacity, our CapEx has been BRL 9.9 billion in 2022, and our growth and transmission lots and solar power and wind power, in addition to our 5 distributors. In terms of growth, we have started the Oitis wind farm and the Luzia wind farm. We've also observed a growth of BRL 200 million in RAP, coming from the acquisition of new transmission operation lots. We also were granted two lots in the June 2022 auction.
Our management board has approved our ESG targets for 2025 and 2030. There are 16 goals from the environment, social and governance points of view, reaffirming our commitment to sustainability. In addition, we've had the rotation of assets with an asset exchange with Elektro Redes S.A., where we are going to have 100% of an operation and an addition of other operations to our distribution. This is an operation that adds a lot of value to Neoenergia and simplifies our structure. It increases our commitments to the following semester. At last, we've concluded 2022 as the year with a great turnover. With less than two years of management, we have managed to fit into the regulatory framework, all our operations. As a consequence, we more than tripled EBITDA, confirming our success in our management strategies.
We've been achieving robust and sustainable results over 2022. Moving to slide five. Since 2017, we have operated other operations such as Hidrocoroá, acquiring control of the company. We have over exceeded by far the predictions for our IPO. Our gross margin has grown 126% over these years, an average of 18% per year. The reflection of our acquisition of distributors and acquisition and renewables. Moving to Opex, there is no shadow of doubt in terms of our commitment with lowering costs and increasing efficiency. Over this period, we presented an average growth of 4% against the inflation rate of 35.5% with IPCA. IGPM rate of over 76% in the period. We have expanding our clients and customers over our five distributors.
EBITDA on its in turn, has grown 216% with an average growth of 26% over the year. While net income has increased substantial 792%, an average of 55% per year. Moving to slide six, we present the evolution of our new transmission and renewables project. When it comes to transmissions, we continue to make progress in all fronts. A few weeks ago, we have delivered the Rio Formoso project with 25% CapEx and savings in 14 months anticipation. This is an important asset for reinforcing the growth of our distribution operations in Bahia. In 2023, we will be delivering approximately 400 new RA, which represents a vast majority of the Brazilian market. By 2022, we had obtained all the permits necessary, and the work is in progress.
In 2021, by December, we observed 21% of progress, we've already fulfilled our obligations with environmental licensing. In terms of the assets purchased in June 2022, we have already contracted CapEx with commodities and currency hedge. 92% already contracted for lot two and 97% for lot 11. That's therefore reducing the risks and guaranteeing the delivery on our premises. We have also achieved the possibility to purchase a lot in the state of Minas Gerais, which puts us in a spotlight in terms of waivers obtained. Moving to renewables, we have great news to share. Our Oiti complex already counts on 390.5 MW in operation, confirming the success of the execution of this process, which will reach 566.5 MW by April this year.
guaranteeing return on the investment. When it comes to the Complexo Luzia, we are almost fully operational. We've achieved 145 MW in operation and will be delivered 149 in the next months. We'd also like to emphasize we've completed Chafariz wind complex, which complement this project. We've expanded transmission lines to connect this wind complex, increasing our results. Moving to slide seven, to conclude my share of this presentation, I'd like to share with you the excellent performance of Neoenergia Brasília in 2022. As I've said before, it represents the final delivery of turnaround in the distributor. After eight consecutive quarters of reduction, we've achieved 11.42%, managing to stay within the regulatory limit.
In terms of quality, as a reflection of the management changes we've executed, we were able to reduce our regulatory limit. In terms of OpEx, we are reaching a whole other level of expenditures, this represents our relentlessness when it comes to reducing operating expenses, reducing 27% in comparison to 2022, the year of the acquisition. In terms of collection, we have gone up from 90% in February 2021 to 97% in December 2022. Also comes from increasing our efforts in collection. We now have our predictions for 2023, and we have amazing potential for Neoenergia, which shall be one of the most efficient distributors in our group. Now I'd like to yield the floor to Leonardo, our CFO, who will offer more results from 2023, 2022. Leonardo.
Hello. Good morning.
As Eduardo has mentioned, we are very happy with the results from 2022, where we've shown an excellent growth and performance in all segments. When it comes to the results, I'm gonna focus on the fourth quarter, which just like the previous quarters, was very consistent. Moving to slide nine, we see the evolution of gross margin. Except for the non-cash flow results, our margin has grown 14% over the quarter, especially due to the B share of readjustment and the increase of renewables with Cortes, Oitis, and Luzia, and also with Liberalize, such as Termopernambuco. This quarter, we continued to present good performance in terms of OpEx with a growth of 10% in comparison to the fourth quarter of 2021, considering the increase of customers in this period. Moving to slide 10 with EBITDA.
EBITDA has shown a growth of 18% over the quarter, while the cash EBITDA, except for the non-cash flow items, in addition to the asset swap with Eletrobras and Belo Monte, which we have achieved in the fourth quarter of 2021. The increase of cash EBITDA was 16% in comparison to the same quarter last year, reaching BRL 2.485 million. Over the year, the increase has been 32%, mostly due to tariff adjustments, and this has been a very strong year. Over the quarter, we've shown a net income growth of 47% in comparison to the fourth quarter of 2021 at a 20% increase over the year between 2021 and 2022 with the incorporation of Bahia PCH by Neoenergia Brasília. Moving to slide 11, now talking about CapEx.
This quarter, we have accomplished BRL 2.774 million in results, while we have invested a lot in distribution, we've achieved BRL 213 million in renewables. Over the year, we've reached a CapEx of BRL 9.900 million, which is comparable to our plan, which was BRL 10 million in the year. This has been the greatest year in terms of CapEx for Neoenergia, improving our capacity to execute. Moving to slide 13, when it comes to the networks and distribution. Starting with the operational performance on this slide, we can observe the variation of injected energy, which has shown a reduction in this quarter as we had anticipated and communicated to the market. Over the quarter, we were once again impacted by lower temperature, more rain, and customers migrating to distributed generation.
Both Coelba and concerned Neoenergia and Elektro will have lower provisions for tariff adjustments over the year, and this is positive for the 2020 market, also mitigating any other impact. On slide 14, you can observe the data on energy distributed, also anticipating the market for the five distributors. In the fourth quarter, the five has shown a reduction of 1.4%, and the total number of customers has reached 16 million for an increase of almost 300,000 customers in three months. Moving to slide 15, when it comes to total losses, we have had a very good performance quarter with a trajectory of reduction across almost all the distributors, except for Coelba and Elektro, but with very controlled losses, both very close to the regulatory limit. Highlight in this quarter is for Neoenergia Brasília with excellent performance.
With it is already within the regulatory limit with two years before we anticipated. Now, on slide 16, when it comes to default, that is well under control in comparison to other quarters. PCLD has been within the threshold and below the third quarter, which is a result from our collection efforts and all the payment methods made available to the customers, which allowed us to increase collection over all the distributors as can be observed at the bottom of the slide. On slide 17, when it comes to DEC and FEC, we have these two quality indicators across our distributors with very good performance. It's out of the rank all this year. We should emphasize that Neoenergia Brasília is within regulatory limits, both in DEC and FEC in the last quarter. Moving to results. Still talking about networks on slide 18.
We have observed an evolution of 68% in gross margin. Here we see the cash, except for the non-recurrent events known by tariff adjustments, the parcel, and the inclusion of new transmission lots, which has had an impact on the quarter. OpEx in the quarter has shown a growth of 10%, whereas the accrued over the year was 11%. Jumping to EBITDA for networks. The cash EBITDA has grown 18% in the past quarter, reaching BRL 2,112 million. In this case, this was caused by tariff adjustments and also the inclusion of new transmission lots. Net income in networks has reached BRL 1.054 billion in the fourth quarter, a slight reduction in comparison to the fourth quarter of 2021. Now, to slide 21, at renewables.
We have a summary of this line of business, again, with very powerful performance, reaching BRL 313 million, a growth of 56% in comparison to the fourth quarter of 2021, with the exception of non-cash flow events. EBITDA has grown 20% for wind power, even more so. The explanation here is due to the new projects of Chafariz and Oitis wind complexes in 2021. The net income was BRL 314 million in comparison to the third quarter of 2021. When it comes to liberalized assets, we have had an EBITDA of BRL 1.011 billion. Still a very good result, especially for Termopernambuco, reaching increase. Because it was operated, we have benefited from a lower purchase price in PLD.
We've also shown a BRL 35 million over the year. The last slide of my presentation, which is slide 25, talking about capital structure. With regard to the structure, we observed that we've closed 2022 with a net debt of BRL 36 billion and almost BRL 500 million, an increase in comparison to the third quarter, basically due to the CapEx plan. However, our reduction of net debt is in line with the third quarter and the past quarters. Our net structure is very comfortable, well-distributed, reaching an average of five years term, a very diversified debt portfolio, and also in terms of indexes. In 2022, we have paid over BRL 13 billion in new acquisitions, whereas this year was the highest CapEx in our business.
For 2023, we have anticipated less than that because part of the needs are already hired, and we have already anticipated our needs for the first quarter this year with funding that we can rely on. This gives us a lot of tranquility to move into 2023, whereas the biggest effort are behind us in 2022. I'd like to ask the operator to open for Q&A.
Excuse me, ladies and gentlemen. We will now begin the Q&A session. To ask a question, please press star one. To remove the question from the list, press star two. Please wait while we collect your questions. Our first question comes from Julia Zaniolo from Santander.
Good morning, everyone. Thank you for the conference call. I'd like you to comment a bit more on the interest of Neoenergia and the cost, asset.
Does it make sense as a capital acquisition means? Do you have any idea on the timing for the conclusion of the plan? I'd like you to comment a bit more on the next transmission operations this year. We're gonna have three large auctions, and I wonder how Neoenergia feels about these auctions and what kind of competitive environment do you expect for it?
Okay. Julia, thank you very much for your question. To answer your first question. As usual, we are observing the market and analyzing opportunities, and distribution is a business that indeed we like. For the next three years, we have over BRL 5 billion of CapEx, organic growth. In addition, our distributors each year have been establishing more and more with this investment.
We are analyzing, we're looking into it, but we're not making specific plans for that because the market is very volatile at the moment. We have an organic growth that allows us not to need more acquisitions in the near future. As to the timing, I am not sure, because it depends a lot on those who are selling the assets, so I wouldn't be able to provide you with a whole lot of information. As to your second question about 2023, especially in terms of volume, it's a large volume. A large volume of lot up to December. Of course, Neoenergia is looking into it as we have done in the past five years, and we will participate in the auctions.
I believe this has been covered in the past, our policy, our investment policy is very well defined, and we must respect it. At the moment, we are considering the macroeconomic scenario. Inflation is reaching two digits, and this is what we need to be mindful of. We're gonna be very rigorous with that, and we will see as we move on in terms of risks because it's clear to us we have to respect our plan, and that's how it should be.
Our next question comes from Daniel Travitzky from Safra Bank.
Hello, everyone. Can you hear me well?
Yes, we can hear you loud and clear.
Great. Thank you. I just wanted to ask you a question about the partnership streamlining the structure.
What are the next tools we're gonna observe at the company after what do you propose in terms of the next moves by the company?
Daniel, thank you for your question. This topic we've been discussing a lot in the past quarter, we have a plan for our assets that you're very familiar with based on four lines: hydropower, thermal, distribution, and renewables. I would say, in terms of hydropower, we have the asset from Eletrobras, now I can say we are doing extremely well. I cannot provide you more details about this, you can rest assured in the next month we will be calling you to communicate novelties in that aspect. We should expect the plan to go as we predicted.
Great. Thank you.
If you would like to ask a question, please press star one. Once again, I'd like you to be aware that if you want to ask a question, just please press star one.
We are now closing the question and answer session. I would like to yield the floor to Mr. Eduardo Capelastegui for closing remarks. Please, Mr. Capelastegui , you can proceed now.
Thank you very much, operator, once again. I'd just like to share a final message reinforcing our commitment with results with Neoenergia. 2022 was a year of many victories, great results. Once again, we present a consistent result which confirms our sustainable strategy and continuous creation of value for our shareholders. Since the IPO, our EBITDA grew 99.5%. Our net income over 100%. This clearly shows our resiliency and resilience and our commitment to results. In terms of our asset rotation plan, as I've answered in the question, it continues to advance. We already had the first results in 2022. We with the assets from Eletrobras, and we remain confident in delivering operations that unlock value in our portfolio. Thus increasing the results even further.
We also continue to advance in our growth projects and transmission and renewables. With the conclusion of Oitis at Luzia and with transmission. Our business fronts, we are very proud to have approved our ESG goals this year, which we believe to be fundamental for our future with actions integrated into our day-to-day business and keeping us at the forefront of the country's energy transition. In terms of our financial health, we remain vigilant, ensuring an adequate capital structure with access to the most different sources of financing, whether they're domestic or international, which reassures us in terms of liquidity. This is very important, especially during times we are experiencing now with a lot of local volatility. Access to international lines of financing allows us to obtain financing at cheaper prices.
To our shareholders who trust in our work, I would like to emphasize once again that we have the right team engaged and committed to deliver the desired results. I would like to conclude by thanking once again all Neoenergia employees who continue to diligently fulfill their role guaranteeing clean, accessible, and quality energy to all our customers. Thank you very much and have a good day.
