3Q10 Relevant Results Analysis of Combined Financial Results (In USGAAP) Revenues increased 65.2% to US$105.7 million in the third quarter 2010 compared to the same period of 2009. These results were mainly driven by: (i) higher contracted sales by US$36.1 million, primarily due to an increase in demand which resulted in a higher quantity of energy sales, and higher prices which are indexed monthly to the NYMEX natural gas prices; (ii) higher spot sales by US$4.3 million; and, (iii) an increase of US$1.3 million in natural gas & other sales.

For the nine months ending September 30th, 2010, Revenues totaled US$284.6 million, an increase of 71.4% as compared to the same period of 2009. This result was mainly caused by: (i) higher contracted sales by US$79.0 million, basically to higher prices and higher energy volume; (ii) higher spot sales by US$37.3 million primarily due to higher generation and higher average spot prices; and (iii) higher other sales by US$2.3 million due to higher natural gas sales. It should be noted that lower generation during the nine months ended on September 30th, 2009, that drives the variations described above, was driven by Andres’ limited capacity operation during part of this period.

Revenues consist of the following:

Operating Costs and Expenses increased 78.6%, in the third quarter 2010, to US$60.9 million compared to the same period of 2009. This variance was principally a net result of: (i) higher cost of sales by US$25.0 million, primarily due to higher fuel cost derived from higher generation and higher LNG prices; (ii) Higher operating maintenance and general expenses by US$2.1 million; (iii) positive impact due to derivate instruments by US$1.9 million; and, (iv) higher depreciation expenses by US$1.6 million.

Operating Costs and Expenses for the nine month period ending as of September 30th, 2010, increased 34.3% to US$172.9 million compared to the same period in 2009. This variance was mainly caused by: (i) higher cost of sales by US$43.3 million derived from higher generation, the related increase in LNG consumption combined with higher LNG prices; (ii) higher depreciation and amortization of intangible assets by US$2.7 million; (iii) higher operating, maintenance and general expenses by US$0.8 million; partially offset by a (iv) positive impact due to derivatives instruments by US$2.6 million.

Total Other Expenses were US$13.1 million in the third quarter 2010 compared to other Expenses of US$9.2 million in the same period of 2009. This increase was mainly a net function of: (i) higher other expenses by US$4.0 million (Gain on sale of investments as result of Sovereign Bonds sold and the insurance reimbursement from the transformer failure were booked during this period in 2009); (iii) higher commercial interest income by US$0.2 million; and, (iv) Lower foreign currency gain by US$0.1 million.

As of September 30th, 2010, Net Expenses increased to US$36.8 million, as compared to total expenses in the same period of 2009 of US$34.6 million. This variance was primarily a result of: (i) higher other expenses by US$8.1 million; (ii) favorable asset impairment by US$7.3 million; (iii) lower net commercial interest income by US$2.0 million basically due to lower account receivables; (iv) lower deferred financing cost amortization by US$0.6 million; (v) lower interest financial expenses by US$0.4 million; and, (vI) lower foreign currency gain by US$0.4 million.

Net Cash Used in Operating Activities was US$0.2 million for the third quarter 2010 compared to a Net Cash Provided by Operating Activities of US$4.7 million in the same period of 2009, mainly due to the following: (i) Negative impact due to higher accounts receivables by US$13.1 million; (ii) positive impact from higher net income by US$11.0 million; (iii) negative impact due to lower accounts payables by US$10.8 million; (iv) positive impact of lower inventory by US$5.5 million; and, (v) positive reconciling adjustment by US$2.5 million reconciling net income to net cash used in operations.

Net Cash Provided by Operating Activities for the nine month period ending September 30, 2010 was US$52.4 million compared to a Net Cash Provided by operating activities of US$1.5 million for the same period in 2009. This variation was primarily the result of: (i) higher net income by US$56.7 million; (ii) higher income tax paid by US$22.2 (Andres did not pay income tax in advance during 2009); (iii) lower accounts payable by US$20.8 million; (iv) lower accounts receivable by US$17.6 million due to collections in March 2010 that resulted from Government Stand-By Agreement with the IMF and the subsequent positive timely payment by the Government for the remainder of this period; (v) lower inventory by US$13.6 million; and, (vi) US$6.1 million higher positive reconciling adjustments, reconciling net income to net cash provided by operations.

Free Cash Flow (a non-GAAP financial measure defined as net cash from operating activities less capital expenditures defined in the accompanying financial statement as Additions to Property, Plant and Equipment and advances to suppliers in purchases of PP&E) was net cash used of US$2.8 million for the third quarter 2010. In addition to the net cash used in Operating Activities of US$0.2 million, during this period, there were additions to property, plant and equipment of US$2.6 million.

As of September 30th, 2010, the Free Cash Flow was net cash provided of US$44.0 million. In addition to the net cash provided by operating activities of US$52.4 million, there were additions to property, plant and equipment by US$8.4 million.

Financial Debt Summary On October 28th 2010 Andres announced an offer to purchase all of its outstanding international Notes, through a Tender Offer th th expiring on November 26 , 2010.

Collection Rate

In the third quarter of 2010, the average collections rate stood at 69% compared with 72% registered in the same quarter of 2009. The reason for this decrease is basically that the Distribution Companies did not receive the subsidy fund from the Government on time during September.

Operational Results In the third quarter of 2010, the Combined Net Generation was up by 45.1% relative to the third quarter of 2009, from 621 GWh in 2009 to 901 GWh in 2010, primarily a result of DPP operating as a base load power plant during this period. Total Energy Sold during 3Q10 was 901 GWh, an increase of 43.7% compared with Q309, a function of the higher generation mentioned above and more UNR clients. During the third quarter 2010, Andres’ Firm Capacity increased 13.9% to 263MW, and the EFOR was 0.1.

DPP’s Firm Capacity increased 35.3% as a result of higher availability since the operational improvements performed on its units.

As of September 30th 2010, Combined Net Generation was 2,427 GWh, an increase of 55.1% compared to the same period of 2009. This increase was mainly a net result of two factors: (i) Los Mina/DPP was generating as base load power plant; and, (ii) during the first half 2009 Andres’ was operating at limited capacity because of the transformer failure that occurred in December 2008. The Energy Sold increased 46.5% to 2,440 GWh, basically due higher generation, higher UNRs sales and new contracts with EDESur and EDENorte (in 2009, we only had one energy contract with EDENorte). Andres’ Firm Capacity increased 15.9% to 255MW and the EFOR decreased from 18.0% to 0 -- 2009 EFOR was affected by the transformer failure in 2009 and the implementation of several operational improvement initiatives has also helped improve the metrics in 2010. DPP’s EFOR decreased 92% primarily a result of the replacement of Turbines Control System.
