are presented the first 30 tons electric mining truck, with the incorporation of six electric buses for transportation of the employees. Enel X is also implementing the necessary charging infrastructure for the operations. This is an important step for the mining indul- industry in Chile, where a co- <cough> complete process has been, is being made in mitigating emissions at the core of the mining operations. Regarding the decarbonization of inaudible and final consumer, we have achieved the milestone of replacing 110,000 inaudible stoves with ef- effi- efficient electric or air conditioning inaudible within Chile. inaudible reduce CO2 emissions, and improve the wellbeing of our cities and communities, benefiting more than 40,000 people. Finally, in the face of efficient lighting in our cities, an ex- expand and consolidate operations in regions with the work of maintenance service of the public lighting system, inaudible of Temuco, with more than 32,000 public lighting, that allow us to reach 340,000 points of light, of which 50% correspond to projects carried out of inaudible, lighting our cities efficiently, and increasing the safety of the citizens. Now let's go to network, page six. Energy distribution improvement reflects the recent inaudible of the sanitary conditions, showing a partial recovery when comparing to the inaudible. Our efforts and investment have allowed to increase the quality of our service, without inaudible by 16%. Our investment in this inaudible continues to improve the inaudible with our clients. In this period, almost 90% of our contacts <cough> with our clients have been executed through inaudible. Let's now move to the basic service load. Within the extension, within inaudible extension, until 1st, the 1st December, 2021- extension until 21st, December, 2021. The application was such a low, if they still affecting the level of overdue debt. As of September, they reduced average eight, $180 million. In order to minimize this impact, we continue to promote payment agreements, with the aims at reducing the overdue accounts. By September, 2021, in more than one year, we have reached more than 58,000 payment agreements with our clients, of which 53% correspond to the tax service law. Moving to collections, the ongoing process for the updates to inaudible of our billing system, as important leap in the digital transformation process of our company, have temporary worsened our KPI versus previous quarters. We expect a normal- normalization of the collection rate during the next quarter. A quick update on regulation. On the commercial, we expect that the consultant report on the reference model will be released during November. This, if this date is confirmed the regulator's uh, final report could be issued early next year. Considering the challenge of potential discrepancies to the tax planners, the final distribution tariff decrease is expected to be released during later 2022. On transmission, we have answered in the expert paraphrase. All discrepancies are swirling to the front of the order report, on the transmission system for the period of 2020, 2022 were already presented. As a result, we expect that the new VAT shall be published early 2022. Thank you, and now I will hand over to Tusette. Thanks, Paolo. Let me start with the summary of our financial highlights on slide eight. Before starting, let me explain the extraordinary aspect of the period. 2021 adjusted a bit up in net income, considered the fact arising from the coal stake impairment associated to inaudible two and the voluntary retirement program announced last quarter. The coal stock impairment and the voluntary retirement program had an aggregated effect of $56 million and $39 million, respectively in EBIDA. And at the bottom line, in cumulated figures. In the third quarter of 2021, the coal stock impairment amounted to $11 million in EBIDA and $8 million in the gross net income. For cumulated figures in 2020, the adjustment coming from the coal stock impairment is 2020, $22 million in EBIDA. In the next excerpt of the impairment of inaudible two, is $659 million at the bottom line. All instance are described in the bottom of the slide. Now, on cap X, the plan is on slide nine. 2021 accumulated cap X reached $735 million, largely devoted to the construction of our new renewable capacity. Customer cap X totaled $49 million, mainly allocated to build new connection and to implement the new commercial fees. Asset management cap X reached $86 billion, 21% higher than nine months, 2020, mainly due to the maintenance of the new, high voltage product, awarding in 2021 another militarization project. Development cap X reached 60 hundred, $600 million, largely driven by our renewable expansion program and development of our distribution business to continue the digitalization of our network. Let's now start with the third Q adjusted EBIDA breakdown on slide 10. That accounted $93 million, 71% lower versus 2020 figures, mainly due to higher PPE sales in the third Q, 2021, finally explained by the new agreement started in 2021 with mining companies inaudible America and BHP. Per adjustment due to the indexation and the new contract coming from NL Distribution fleet customer portfolio at the beginning of the year. Hydrology. Lack of Argentinian gas and higher elementary international prices explained the main varieties of this quarter. That demanded us to increase the volume of purchases at the higher prices versus last year. Let me explain each challenge that are included in the slides. First purchase is volume. Represented the valuation of almost $120 million, mainly explained by the lower hydro generation. Total purchases cost represented an increase of around $90 million. Variable production cost, partially offset by the aging contract for inaudible, represented a variance of around $100 million. In gas margin represented a positive variance of $6 million in our EBIDA, as an increase of our natural gas trading activity in the market. Following the chart, we have also in the period, variances coming from a recovery of the third Q, 2021, demand in distribution business. Mainly in the regulated customer, due to the release of the lockdown measures and the setbacks that government planned. Next was the recom- remonetization, mainly related to the provision on lowering remuneration on distribution types, which should be retroactive to November, 2020, and in the lower remuneration of transmission type, inaudible of the indecision of the tally. Other aspects accounted for $18 million, mainly related to a higher analyzed EBIDA in the quarter, mainly due to the public lightening bi- business. Lower penalty and compensation costs in distribution business due to a better quality indicators and the inaudible during the third Q ' 20 on reading sales this cost, due to the logistics regi- restriction. Let's move now to slide 11, where we have the summary of nine months adjusted EBIDA breakdown accounting for $536 million. 39% lower, versus 2020 figures. As you can see, the main affect are the same that were presented in the third Q. Higher TPA sales in the nine months, 2021, due to the new agreement already mentioned, which started in 2021. Higher pot- parts of this volume during the nine months with an affect of $160 million. The increase in the stock price due to the DOW and for the commodity availability and other higher commodity
