execution as of September was $946 million. Mainly allocated to the progress in the construction of energy transmission projects in the countries where the company operates. ISA estimates, a year end execution of sector $1.2 billion. Please turn to the next slide to review the company's cash flow. Cash balance for the third quarter was 13.1 trillion pesos. With the operating cash flow adding 11.5 trillion pesos. ISA contributed 6 trillion pesos to the cash balance and 0.5 trillion to the operating cash flow, respectively. The investment component for the year presented an outflow of 8.8 trillion pesos related to CapEx. The financing component, excluding ISA acquisition, registered an outflow of 2.8 trillions pesos for principal and interest payments. During 2021, dividends for 1.4 trillion have been paid to Eco Patrol shareholders and to non-controlling shareholders of its subsidiaries. Final cash balance, considers cash and cash equivalence for 10.1 trillion pesos and a short-term investment portfolio of 3 trillion pesos. The Eco Patrol Group's cash composition is 64% dollar-based and 36% Columbian peso-based. This cash balance does not include the account receivable from the full price deviation fund, for pe- for it's a Spanish acronym, which at the end of 3Q amounts to 7.2 trillion pesos. It is worth mentioning that the recently approved general budget of the Republic of Columbia includes a specific provision of 2.7 trillion pesos for the recognition of this item, as well as additional budgetary mechanisms to address the remaining amounts. Please turn to the next slide. Finally, we would like to highlight the completion of our first external liability management transaction for $2 billion, by which we partially refinance the 3.7 billion loan associated with the ISA acquisition. This transaction optimizes the debt maturity profile of the Eco Patrol Group, with market rates at historically low levels since 2014. The transaction had a robust demand from around 270 investors from different geographies globally with individual bids of up to $470 million. Evidencing confidence in Eco Patrols financial strength. This transaction, in addition to the approval of the program to issue common stock in Columbia, by the Superintendency of Finance, provides flexibility and access to different sources of debt and equity financing with the objective to continue optimizing the maturity profile and to fund the energy transition strategy of the company. Now I hand over to the CEO for closing remarks. Thank you, Hyman. We continue to move forward on each of the pillars of our TESG strategy. On the environmental side, we particularly highlight achievements in our renewable energy projects with the entry to operation of the San Fernando solar farm that is located in the Meta department, we have now an additional install capacity of 61 Megawatts that will supply part of the energy demand for both Eco Patrol and sending operations. It will also help us to avoid emissions for more than 508,000 tons of CO2 equivalent during the next 15 years and will contribute to the group's decarbonization plan. All this in addition to over 21,000 tons of CO2 emissions that have already been avoided by the Castilla solar farm in its first to use of operations since October, 2019. During such period, we have also saved with the Castilla Solar Farm, some $2 million in operational costs. With San Fernando, the group's current capacity on renewable energy stands at 112 Megawatts. Likewise, Eco Patrol inaugurated the gas based self-generation plant in Chichi Meme that will avoid emissions of some 44,000 tons of CO2 each year and will supply part of the energy required by the Chichi Meme apply CPO9 and Castilla yield all located in the Meta department. In terms of hydrogen, we highlight the active participation of Eco Patrol as one of the key players in the construction of Colombia's hydrogen roadmap aimed at developing this energy source for the country. On the other hand, we recently joined the group of the task force of on nature related financial disclosures, TNFD to help develop a reporting framework for nature related risk and opportunities, as well as mitigating negative impacts on the environment. Last week, we participated in COP26 in Glasgow as one of the organizations representing Colombia. In addition to discussing actions that allow to mitigate climate change impact, we met with different leading organizations to explore potential alliances in the development of several opportunities on our road to net zero and energy position roadmaps. Regarding technology, I wanna highlight the capture of some $36 million year to date of benefits from our digital transformation agenda. Also, the award of the sustainable development goals, good practices led by the global compact of the UN to our open innovation program, a hundred times a hundred. In the social dimension Eco Patrol achieved the Equipares Silver Seal, a certification with a 98.47% score, which gives us now five companies in the group that have favorable processes for gender equality. Let's move on now to the conclusions. During the quarter, we achieved significant progress towards energy transition, such as the closing of the ISA acquisition, setting a milestone in the history of the country and for both companies. Providing the opportunity to consolidate the Eco Patrol Group as a new leading energy company with greater capacity to continue generating sustainable value. We continue delivering strong financial results to our shareholders and our groups of interest. We will keep consolidating our integrated strategy, maintaining the focus on the core business while moving forward in the pillars of energy transition.
