Thank you, Doron. Let me start my review of our financial performance on Slide 8. Total revenues for the quarter were $159 million, down 7% and cost of revenue decreased 9% to $105 million. The net result was a decrease in gross profit of 3%. However, gross margin increased from a 32.5% last year to 34% this quarter.
Moving to Slide 9 for more details on our electricity segment. Revenues for the quarter in our electricity segment were $124 million, in line with same period last year. This quarter, we benefited from increased revenue in Steamboat Hills, Ormesa and Brawley, offset by lower revenues in Olkaria as a result of the curtailment during this period.
Cost of revenue this quarter included business interruption insurance income related to Puna of $2.6 million, out of a total of $20.4 million via insurance income received this quarter. This compared to $1.2 million included last year in gross margin.
As a reminder, on the GAAP, we allocate the proceeds from the business interruption insurance, first, the cost of revenue of the electricity segment; and when that is exhausted, the balance is allocated to insurance income under operating expenses under a separate line item in the P&L.
Turning to Slide 10. As expected, product segment revenue were lower in the quarter by $13.4 million compared to last year due to the continuing impact of COVID-19 on this segment.
On Slide 11, the Energy Storage and Management Services segment generated $5.7 million of revenues, an increase of 62.5% over last year. This segment enjoyed from the Pomona addition, following its acquisition in July, which contributed $2.4 million to our quarterly revenue.
Moving to Slide 12 and 13 for a discussion of our gross profit and margin. The third quarter consolidated gross margin improved by a better performance of both the electricity and storage segments. Gross margin for the electricity segment, demonstrating our efforts to improve efficiency of our operating assets. In the product segment, we see declining gross margin. Mainly due to higher cost of revenue related to the Ngawha project that we are building currently in New Zealand. This project was impacted among other by restriction and limitation in the country associated with COVID 19. The higher cost in Ngawha project this quarter also impacted the full year 2020 gross margin that is expected to be in line with this quarter margin.
Energy Storage and Management Services segment reported a gross margin of 25.6%, a much improved results compared to a negative gross margin in prior quarters. The improvement was driven by addition of Pomona that although carrying $1 million depreciation this quarter, delivering strong profit. We expect Pomona annual run rate of depreciation and amortization to be $4.8 million a year. This was the second consecutive quarter where our energy storage business contributed positive EBITDA to our consolidated results.
Turning to Slide 14. SG&A expenses for the third quarter were $18.6 million compared to $15.7 million last year. The increase is mainly driven by increase in sales commission, insurance expense and other professional services.
Turning to Slide 15. Operating income for the third quarter increased by 33.5%. In this slide, you can see the breakdown of the operating income by segment.
Turning to Slide 16. Net interest expense for the third quarter of 2020 was $21.8 million compared to $20.1 million in the prior period. Interest expense this quarter was negatively impacted by the interest cost of the $290 million bond, which we borrowed early in Q3, while proceeds were used to pay outstanding debt toward the last part of the quarter, including all revolving credit facilities.
The issuance of the $290 million bonds and paying down all available lines of credit enable us to be well prepared to the expected increase in 2021 CapEx to support our U.S. and Indonesia investments.
Turning to Slide 17. Provision from income tax for the third quarter was $15.4 million for an effective tax rate of 39% compared to income tax expense of $10 million for the third quarter of 2019. The this quarter, we had a $3.7 million noncash items tax charge related to a recent change in U.S. laws.
Turning to Slide 18. Net income attributable to the company's stockholders was $15.7 million or $0.31 per diluted shares compared to $15.6 million or $0.30 per diluted shares for the third quarter last year. Net income attributable to the company stockholders benefited from $8.1 million related to Ormat's after-tax portion of Puna insurance income, partially offset by noncash charge of $1.4 million related to Sarulla.
In addition, a recent change in the tax law in the U.S. resulted in a $3.7 million income tax charge. In aggregate, these factors positively impacted our diluted EPS by $0.059 per share.
Turning to Slide 19. Adjusted EBITDA this quarter was $107.1 million, up from $85.5 million last year.
In Slide 20, you can see that the electricity contribution to our total EBITDA increased to 92.5%. Please note that adjusted EBITDA included the full impact of the BI insurance received this quarter. While the impact on EPS reduced by associated tax and by a portion related to our partners. Reconciliation of EBITDA and adjusted EBITDA are provided in the appendix slides.
Turning now to Slide 21. Cash and restricted cash as of September 30, 2020, was approximately $290 million compared to $153 million as of December 31, 2019. This slide breaks down the use of cash for the first 9 months and demonstrate our enhanced ability to reinvest in the business to support our growth plans.
Our long-term and short-term debt as of September 30, 2020, was $1.5 billion, net of deferred financing costs, and its payment schedule is presented on Page 22. The average interest rate on our debt is currently 4.9%. Our net debt as of September 30, 2020, was $1.2 billion.
Turning to Slide 23 that provides an overview of our recent financing activity. These activities, in line with our plans to continue and increase our efforts on exploring and developing of new internal project. With a target to increase our electricity and storage segment in the U.S. and globally in 2023 and beyond.
On November 3, 2020, the company's Board of Directors declared a dividend of $0.11 per share pursuant to the company's dividend policy. The dividend will be paid on December 2, 2020, to stockholders of record as of the close of Business day on November 18, 2020.
Before I call this call to Doron, I want to elaborate on some of the favorable development we had in the international front. In September, we received $20 million from our customer ENEE, in Honduras, for prior year's outstanding invoices.
In addition, we improved collection from KPLC, our customer in Kenya. KPLC has made all scheduled payment for the third quarter and has started reducing overdue amounts starting in October.
Finally, subsequent to the end of the third quarter, we concluded as noted by the Kenya tax authority, also known as the KRA, related to a $190 million tax assessment issued by them in December 2019, and we reached a very favorable settlement. The total net estimated impact on Ormat results, which all of it will be recorded in Q4 2020, is approximately $6 million, only $0.12 per diluted share, including all associated interest and penalties. The settlement covered the years 2013 through 2019 and included deferral of tax benefits that were previously utilized by Ormat, resulting in a payment to the KRA during Q4 of this year of $28.2 million, which the company is expected to recover most of it through lower future tax payments.
We still have 2 unresolved tax assessment at the different stages of negotiation in a total amount of $9 million, including all interest and penalties.
That conclude my overview. Now -- I would now like to turn the call over to Doron for any operational and business update. Doron?
