ORMAT TECHNOLOGIES REPORTS SECOND QUARTER 2011 RESULTS
Q2 net income of $8.2 million with increased total revenues of $104.6 million
Product backlog reached $225 million

(RENO, Nev.) August 3, 2011 — Ormat Technologies, Inc. (NYSE: ORA) today announced financial results for the second quarter of 2011.

Quarterly highlights:

•

18 percent increase in electricity revenues;

•

11 percent increase in electricity generation; and

•

the largest product order which led to a record high backlog.

Commenting on the results, Dita Bronicki, Chief Executive Officer of Ormat, stated, “The second quarter was highlighted by strength in electricity operations. The good performance of most of our plants translated into growth in generation and in revenues from electricity, which increased to $81.2 million.

“We successfully secured new contracts for the supply of geothermal power plants and other power generating units. During the quarter we received a supply and engineering, procurement and construction (EPC) contract from New Zealand, which has a collective value of approximately $130 million. This represents the largest product order in our company’s 46-year history, and, as a result, the product backlog increased to approximately $225 million.

“During the quarter, we also have made additional progress toward diversifying our future development portfolio by entering into a build, operate and transfer (BOT) agreement with Tikitere Geothermal Power Limited (TGL) to explore, develop, supply, construct, own and operate a 45 MW geothermal power plant in New Zealand.”

Financial Summary

Second Quarter Results

For the three months ended June 30, 2011, total revenues were $104.6 million, compared to $96.3 million in the second quarter of 2010. Electricity revenues increased by 18.0 percent to $81.2 million, up from $68.8 million in the second quarter of 2010. Electricity revenues in the quarter include $4.8 million relating to our North Brawley power plant with corresponding cost of revenues of $10.4 million. Total generation increased by 11.2 percent and the average revenue rate of electricity operations was $83 per MWh, up from $78 per MWh in the second quarter of 2010. Product revenues for the three months ended June 30, 2011 were $23.4 million, compared to $27.5 million in

the same period in 2010. Product revenues in the quarter include $7.9 million relating to an experimental REG plant in an LNG terminal in Spain.

For the quarter, the company reported net income of $8.2 million, or $0.18 per share (basic and diluted), compared to a net loss of $1.5 million, or $0.03 per share (basic and diluted) for the same period a year ago. The increase is principally attributable to the increase in the gross margins of both our electricity and product revenues.

Adjusted EBITDA for the second quarter of 2011 was $47.7 million, compared to $24.0 million in the same quarter last year. Adjusted EBITDA includes consolidated EBITDA and the company’s share in the interest, taxes, depreciation and amortization related to its unconsolidated 50 percent interest in the Mammoth complex in California in the three months ended June 30, 2010. The reconciliation of GAAP net cash provided by operating activities to Adjusted EBITDA as well as additional cash flow information is set forth below.

As of June 30, 2011, cash, cash equivalents and marketable securities were $67.4 million. In addition, as of June 30, 2011, the company had available committed lines of credit with commercial banks aggregating $407.5 million, of which $196.0 million is unused.

On August 3, 2011, Ormat’s Board of Directors approved the payment of a quarterly dividend of $0.04 per share pursuant to the company’s dividend policy, which targets an annual payout ratio of at least 20 percent of the company’s net income. The dividend will be paid on August 25, 2011 to shareholders of record as of the close of business on August 16, 2011. The company expects to pay a dividend of $0.04 per share in the next quarter.

Commenting on the outlook for 2011, Bronicki said, “We continue to expect 2011 electricity revenues to total $315 to $325 million. We are maintaining our product revenues guidance to be $90 to $100 million.”

Six-Month Results

For the six months ended June 30, 2011, total revenues were $202.4 million, an increase of 13.1 percent from $178.9 million in the same period last year. Net loss for the period was $0.7 million, or $0.02 per share (basic and diluted), compared to net income of $0.3 million, or $0.01 per share (basic and diluted), in the same period in 2010.

Electricity revenues for the six months ended June 30, 2011 were $159.5 million, compared to $134.9 million in the same period a year ago, an increase of 18.2 percent. Product revenues for the first six months of 2011 were $43.0 million, compared to $44.0 million in the same period in 2010, a decrease of 2.3 percent.

Adjusted EBITDA for the six months ended June 30, 2011 was $74.8 million, compared to $56.1 million for the same period a year ago. Adjusted EBITDA includes consolidated EBITDA and the company’s share in the interest, taxes, depreciation and amortization related to its unconsolidated 50 percent interest in the Mammoth complex in California for the six months ended June 30, 2010. The reconciliation of GAAP net cash provided by operating activities to Adjusted EBITDA, as well as additional cash flow information is set forth below.

Reconciliation of EBITDA and Adjusted EBITDA and Additional Cash Flows Information
For the Three and Six-Month Periods Ended June 30, 2011 and 2010
(Unaudited)

We calculate EBITDA as net income before interest, taxes, depreciation and amortization. We calculate adjusted EBITDA to include depreciation and amortization, interest and taxes attributable to our equity investments in the Mammoth complex. EBITDA and adjusted EBITDA are not measurements of financial performance or liquidity under accounting principles generally accepted in the United States of America and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net earnings as indicators of our operating performance or any other measures of performance derived in accordance with accounting principles generally accepted in the United States of America. EBITDA and adjusted EBITDA are presented because we believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of a Company’s ability to service and/or incur debt. However, other companies in our industry may calculate EBITDA and adjusted EBITDA differently than we do. The following table reconciles net cash provided by operating activities to EBITDA and adjusted EBITDA, for the three and six- month periods ended June 30, 2011 and 2010:
