Good afternoon, everyone, and thank you for participating in today's conference call. I would now like to turn the call over to Mr. John Ciroli, as he provides some important cautions regarding forward-looking statements and non-GAAP financial measures contained in the earnings materials or made on this call. John, please go ahead.
Thank you, and good afternoon. Welcome to Montauk Renewables Earnings Conference Call to review the third quarter 2023 financial and operating results and development. I'm John Ciroli, Chief Legal Officer and Secretary at Montauk. Joining me today are Sean McClain, Montauk's President and Chief Executive Officer, to discuss business development, and Kevin Van Asdalan, Chief Financial Officer, to discuss our third quarter 2023 financial and operating results. At this time, I would like to direct your attention to our forward-looking disclosure statement.
During this call, certain comments we make constitute forward-looking statements, and as such, involve a number of assumptions, risks, and uncertainties that could cause the Company's actual results or performance to differ materially from those expressed in or implied by such forward-looking statements. These risk factors and uncertainties are detailed in Montauk Renewables' SEC filings. Our remarks today may also include non-GAAP financial measures.
We present EBITDA and Adjusted EBITDA metrics because we believe these measures assist investors in analyzing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. These non-GAAP financial measures are not prepared in accordance with the generally accepted accounting principles.
Additional details regarding these non-GAAP financial measures, including reconciliations to the most directly comparable GAAP financial measures, can be found in our slide presentation and in our third quarter 2023 earnings press release and Form 10-Q, issued and filed this afternoon. Those are available also on our website at ir.montaukrenewables.com. After our prepared remarks, we will open the call to questions. We ask that you please keep to one question to accommodate as many questions as possible. With that, I will turn the call over to Sean McClain.
Thank you, John. Good day, everyone, and thank you for joining our call. During the third quarter of 2023, industry-wide D3 RIN generation decreased approximately 8% when comparing RIN generation in July 2023 to September 2023, as reported by the US EPA. This compares to an approximately 6.6% increase in industry-wide RIN generation from July 2022- September 2022.
We believe contributing factors to the Q3 2023 reduction in D3 RIN generation could include drought, weather anomalies of lower than average rainfall and higher than average temperatures. As some of our production facilities experienced these weather anomalies, and as Kevin will explain more, our production during the third quarter of 2023 was similarly impacted.
In the third quarter of 2023, our board of directors approved funding for the first phase of our swine waste to renewable energy development initiative in North Carolina, including the approximately $24 million of cumulative expenditures through Q3 2023. We currently expect the first phase total capital investment to range between $140 million-$160 million.
We currently expect to have the first of eight processing reactor trains operational during the first half of 2024. We are currently planning for a rolling commissioning schedule for the remaining processing lines, beginning in the second half of 2024 and continuing through the second half of 2025. We expect revenue generation to commence in 2025.
Upon completion of this first phase of the project, we expect to have sufficient capacity to satisfy the Duke Energy REPS contract through the deployment of up to eight of our patented reactors. At first full phase processing capacity, we anticipate the ability to process feedstock from over 120,000 hog spaces per day, equating to over 200 tons of waste collection per day.
The first phase of this project is expected to produce approximately 45,000-50,000 MWh equivalents through a combination of 190,000-200,000 MMBtu and 25,000-30,000 MWh. We also expect the first phase of the project will produce approximately 17,000-20,000 tons of char soil enhancement annually.
Related to our Pico Dairy Digestion Capacity Increase project, during the third quarter of 2023, we commissioned additional digestion capacity and our new reception pit. We have begun utilizing the increased reception pit capacity and have been working to increase gas availability through the additional digestion capacity. We expect to commission the last expansion of our digestion capacity increase during the fourth quarter of 2023 that will be necessary to process the final tranche of increased feedstock.
Our dairy host informed us they expect to deliver that final increase in feedstock volumes in 2025, at which time we will make the final contractual payment to the dairy. With that, I will turn the call over to Kevin.
Thank you, Sean. I will be discussing our third quarter of 2023 financial and operating results. Please refer to our earnings press release and the supplemental slides that have been posted to our website for additional information. Total revenues in the third quarter of 2023 were $55.7 million, a decrease of $0.2 million, or 0.3% compared to $55.9 million in the third quarter of 2022.
The decrease is primarily related to a decrease in pricing of the gas commodity indices, which decreased 68.9% during the third quarter of 2023 as compared to the third quarter of 2022. Similarly, realized RIN prices decreased 12.6% to $3.05 in the third quarter of 2023, compared to $3.49 in the third quarter of 2022.
Contributing to the revenue decrease are gains recognized in the third quarter of 2022 of $0.4 million, related to a gas commodity hedge program that has since expired. Offsetting these revenue decreases was an increase of 26.7% of RINs sold in the third quarter of 2023, as compared to the third quarter of 2022.
Total general and administrative expenses for the third quarter of 2023 were $7.8 million, a decrease of $0.7 million, or 8.2%, compared to $8.5 million in the third quarter of 2022. The decrease was primarily related to a decrease of $0.7 million or 13.9% in employee-related costs, including stock-based compensation. Turning to our segment operating metrics, I'll begin by reviewing our renewable natural gas segment. We produced 1.4 million MMBtu of renewable natural gas during the third quarter of 2023, a decrease of less than 0.1 million, compared to 1.4 million MMBtu produced in the third quarter of 2022.
As Sean mentioned, industry D3 RIN generation decreased approximately 8% when comparing RIN generation in July 2023 to September 2023, as reported by the EPA. This compares to approximately 6.6% increase in RIN generation between July 2022 and September 2022. We believe contributing factors to this third quarter of 2023 reduction in industry D3 RIN generation could include drought weather anomalies of lower than expected rainfall and higher than average temperatures.
These weather anomalies have impacted gas availability at certain of our RNG facilities during the third quarter of 2023. Also impacting our production were previously discussed second quarter of 2023 process equipment failures, which impacted the third quarter of 2023, but have since been repaired.
Revenues from the renewable natural gas segment in the third quarter of 2023 were $50.9 million, a decrease of $3.4 million, or 6.3%, compared to $54.3 million in the third quarter of 2022. Average commodity pricing for natural gas for the third quarter of 2023 was $2.55 per MMBtu, 68.9% lower than the third quarter of 2022. During the third quarter of 2023, we self-monetized 13.8 million RINs, representing a $2.9 million increase or 26.7%, compared to 10.9 million in the third quarter of 2022.
Average realized pricing on RIN sales during the third quarter of 2023 was $3.05, as compared to $3.49 in the third quarter of 2022, a decrease of 12.6%. This compares to the average D3 RIN index price for the third quarter of 2023 of $3.01, being approximately 6.4% higher than the average D3 RIN index price in the third quarter of 2022. At September 30, 2023, we had approximately 0.3 million MMBtu available for RIN generation and had approximately 0.8 million RINs generated and unsold.
Of the RINs generated and unsold as of September 30, 2023, approximately $1.5 million in revenues will be recognized during the fourth quarter of 2023, as the transfer of ownership was not completed by the customer until after September 30, 2023. At September 30, 2022, we had approximately 0.4 million MMBtus available for RIN generation and had approximately 1.4 million RINs generated and unsold.
Our profitability is highly dependent on the market price of environmental attributes, including the market price of RINs. Realized prices for environmental attributes monetized in a period may not correspond directly to index prices due to the forward selling of commitments. We have not entered into significant forward sale commitments beyond the fourth quarter of 2023.
We have entered into commitments to monetize all RINs expected to be generated during the fourth quarter of 2023 at an average price of $3.09. Our operating and maintenance expenses for our RNG facilities in the third quarter of 2023 were $11.9 million, a decrease of $0.2 million, or 1.7%, compared to $12.1 million in the third quarter of 2022. Our RNG facilities reported reduced utility expenses of approximately $1.5 million in the third quarter of 2023 as compared to the third quarter of 2022.
Additionally, operating and maintenance expenses at our RNG facilities increased approximately $1.2 million in the third quarter of 2023 as compared to the third quarter of 2022, as a result of facility preventative maintenance, repairs, and other well field operational enhancements.
We produced approximately 48,000 MWh of renewable electricity during the third quarter of 2023, a decrease of approximately 1,000 MWh compared to 49,000 MWh in the third quarter of 2022. Our Bowerman facility produced approximately 3,000 MWh less in the third quarter of 2023 compared to the third quarter of 2022, due to higher ambient temperatures in the third quarter of 2023.
Our Security facility produced approximately 2,000 MWh more in the third quarter of 2023 compared to the third quarter of 2022, due to engine maintenance completed in 2022. Revenues from renewable electricity facilities in the third quarter of 2023 were $4.8 million, an increase of $0.4 million, or 9.2%, compared to $4.4 million in the third quarter of 2022.
The increase is primarily driven by an increase in our RNG facility production volumes and the timing of the generation and monetization of RECs at our Bowerman facility. Our renewable electricity generation operating and maintenance expenses in the third quarter of 2023 were $2.2 million, an increase of $0.1 million, or 4.8% compared to $2.1 million in the third quarter of 2022.
The increase is primarily related to our Tulsa facility operating and maintenance expenses, which increased approximately $0.3 million as a result of scheduled engine preventative maintenance and wellfield operational maintenance. Additionally, our Turkey Creek facility operating and maintenance expenses increased approximately $0.2 million as a result of non-capitalizable costs.
The increase was offset by a decrease of approximately $0.3 million at our Bowerman facility as a result of property tax refund received in the third quarter of 2023. We calculated and recorded an impairment loss of less than $0.1 million in the third quarter of 2023, a decrease of $2.2 million, or 97.8%, compared to $2.3 million in the third quarter of 2022. The impairments in the third quarter of 2023 were for specifically identified RNG machinery and equipment that were no longer in operational use. Other than this discrete event, we did not record any other impairments related to future cash flows.
Operating income in the third quarter of 2023 was $16.8 million, an increase of $3.1 million, or 23.1%, compared to $13.6 million in the third quarter of 2022. RNG operating income for the third quarter of 2023 was $24.1 million, a decrease of $2.7 million or 10.3%, compared to $26.8 million in the third quarter of 2022.
Renewable electricity generation operating income for the third quarter of 2023 was $0.7 million, an increase of $2.4 million, or 141.9%, compared to an operating loss of $1.7 million in the third quarter of 2022. Turning to the balance sheet. As of September 30, 2023, $66.0 million was outstanding under our term loan.
The company's capacity available for borrowing under the revolving credit facility was $117.5 million. During the nine months ended September 30, 2023, we generated $19.6 million of cash from operating activities, a decrease of $40.2 million, or 67.3%, compared to $59.8 million of cash provided by operating activities in the third quarter of 2022.
Of the RINs generated and unsold at September 30, 2023, approximately $1.5 million in deferred revenues was included in working capital as of September 30, 2023, as the transfer of ownership was not completed by the customer until October of 2023. For the nine months ended September 30, 2023, our capital expenditures were $45.4 million, of which approximately $12.3 million were related to the ongoing Pico facility digestion capacity increase.
$9.6 million were related to the Montauk Ag Renewables project in North Carolina. $10.1 million were related to our second Apex RNG facility. $2.9 million were related to our Blue Granite RNG facility, and $2.8 million were related to our Bowerman RNG project. As of September thirtieth, 2023, we had cash and cash equivalents of approximately $73.7 million.
Adjusted EBITDA for the third quarter of 2023 was $22.4 million, an increase of $1.5 million or 7.4%, compared to $20.9 million for the third quarter of 2022. EBITDA for the third quarter of 2023 was $22.4 million, an increase of $3.5 million or 18.2%, compared to $18.9 million for the third quarter of 2022.
Net income for the third quarter of 2023 increased approximately $1.7 million or 15.6% over the third quarter of 2022. With that, I'll turn the call back over to Sean.
Thank you, Kevin. In closing, we would like to provide an updated full year 2023 outlook, driven by drought weather anomalies that are likely a leading cause of the industry reduction in D3 generation during the third quarter of 2023. And while we don't provide guidance on our expectations of future environmental attribute prices, volatility in index prices does impact our revenue expectations. We currently expect RNG production volumes to range between 5.7 and 5.8 million MMBtu.
Corresponding RNG revenues are expected to range between $155 million and $160 million. We expect renewable electricity production volumes to range between 190 and 195 thousand MWh, and corresponding renewable electricity revenues are expected to range between $17.7 million and $18.7 million. And with that, we will pause for any questions.
Thank you. To ask a question, you'll need to press star one one on your telephone. To withdraw your question, please press star one one again. Please wait for your name to be announced. We ask that you please limit yourself to one question until all have had a chance to ask a question, after which we'll answer additional questions from you as time permits. One moment for our first question. Our first question comes from the line of Ryan Pfingst with B. Riley. Your line is now open.
Hey, guys. Thanks for taking my question. Could you just talk about the decision to enter into commitments for all of your, expected RIN generation in 4Q at 309? Was that just out of a, you know, an abundance of caution, and do you expect to enter into commitments in the near term for 2024, given the recent strength we've seen in index prices?
Good question, Ryan. The philosophy that we have on RIN commitments is tied closer to our direct sales to obligated parties. We try to avoid selling our RINs to any intermediaries, and the timing at which we make those commitments is a cross between the strength of the pricing that we see, the abundance or absence of any news to the contrary that would suggest that those prices are abnormal, and the demand interest from those obligated parties.
And that's the extent to which we make the decision on what we monetize or committed for the fourth quarter. As far as the commitments into the upcoming year relative to the price strength, we don't provide forward guidance in terms of commitments beyond our acknowledgment that we haven't made any of those commitments in any material nature as of this point.
But continue to evaluate it no differently than we have in previous quarters and in previous years. Again, combination of the price strength and the demand interest of the obligated parties under the Renewable Fuel Standard.
Thank you. As a reminder, to ask a question, that's star one, one, and please wait for your name to be announced. One moment for our next question. Our next question comes from the line of Craig Shere with Tuohy Brothers. Your line is now open.
Good afternoon. So my apologies, I'm jumping around between earnings calls. It looks like your third quarter was mostly in line, but you're lowering RNG guidance for the year, which implies kind of a softer fourth quarter. Is this primarily relating to this drought issue impacting RNG production? Can you provide a little more color on what might make for a softer fourth quarter?
Yeah, and Craig, that's correct. Our third quarter was impacted by these weather anomalies, significantly, impacting our Ohio facilities and our Texas facilities. That's a primary leading reason for the lowering of the top end of our 2023 guidance. And then I did want to note that our third quarter, while in line, we did have a deferral of approximately $1.5 million in revenues from Q3 into Q4, that we normally would have obtained.
But yeah, the generally, the drought that we experienced for a prolonged period in our third quarter, is the primary reason for the top end of that range being reduced from last quarter to this quarter.
Thank you. One moment for our next question, please. Our next question comes from the line of Matthew Blair with Tudor, Pickering, and Holt . Your line is now open.
Hey, good afternoon. I was wondering if you had any thoughts on why D3 RIN generation appears to have slowed down recently. I think the year-to-date pace is around a 17% growth rate, which obviously is pretty strong. But in recent months, it's been much lower than that. If you're seeing that in your system or if you had any ideas on why things might be slowing down in that regard?
Yeah, Matthew, I think, as we disclosed, we believe that the weather, some, you know, less than average rainfall, higher than average temperatures, we believe that's contributing it to the third quarter. And then while we still continue to review and try to glean information from our systems and information, we do believe that there's that continued growth in the voluntary offtake market as well.
We're aware of that voluntary offtake. You know, we have a portion of our production that is sold under fixed pricing. We have we're working to quantify that, but I believe it's those two leading factors would be contributing to the falling RIN production that we've been seeing as an industry over the last handful of months.
Thank you. As a reminder, that's star one one to ask your question. One moment for our next question. I have a follow-up from the line of Craig Shere with Tuohy Brothers. Your line is now open.
Yes, I was just wondering, could you provide a little more clarity? Because when I asked before, it was a good summary about the third quarter, but it sounded like the weakness was mostly going to be in the fourth quarter. And I was trying to get a better sense of what the drivers were there.
Thanks, Craig, for the follow-up. I apologize for not appropriately addressing. We're working through our various sites that have had impact with these drought conditions. As we bring volumes back from the field, we're anticipating a rebound, but it's, we're being mindful of any contemporaneous issues as we resume vacuum on the field and areas like that. We don't anticipate significant issues currently, but we are being mindful of fourth quarter impacts coming off of this previous summer.
Thank you.
And again, that's star one one to ask your question. I would now like to hand the conference back over to Mr. Sean McClain for closing remarks.
Thank you. Thank you all for taking the time to join us on the conference call today. We look forward to speaking with you again in 2024.
This concludes today's conference call. Thank you for your participation. You may now disconnect. Everyone, have a wonderful day.
