PRESS RELEASE

ORMAT TECHNOLOGIES REPORTS FIRST QUARTER 2012 RESULTS

Record quarterly revenues of $132.4 million and cash flow from operations of $41.9 million;

Q1 net income of $8.0 million

RENO, Nevada, May 8, 2012 - Ormat Technologies, Inc. (NYSE: ORA) today announced financial results for the first quarter of 2012.

Quarterly highlights and recent developments:

Commenting on the results, Dita Bronicki, Chief Executive Officer of Ormat, stated: “We had a very good first quarter. Total revenues increased 35 percent year-over-year, while our combined gross margin almost doubled from the same period last year. Net income significantly improved and we continued to invest in our long-term growth strategy.

“The good results of the quarter are a testament to the continued progress that we have made in both our electricity and product segments. On the electricity side, we see the result of the well field and equipment improvement which increased generation and reduced operating costs. On the product side, we have successfully translated our technological leadership and proven execution abilities into a substantial backlog.”

Financial Summary

For the three months ended March 31, 2012, total revenues increased 35.3 percent to $132.4 million from $97.8 million in the first quarter of 2011. Product revenues more than doubled to $50.1 million, from $19.6 million in the three months ended March 31, 2011. Electricity revenues increased 5.1 percent to $82.2 million, up from $78.3 million in the three months ended March 31, 2011.

Operating income for the three months ended March 31, 2012 increased by $22.6 million to $25.7 million from $3.1 million for the three months ended March 31, 2011. The increase is principally attributable to higher rates and lower operating costs in our electricity segment and higher volumes of customer orders in our product segment.

For the quarter, the company reported net income of $8.0 million, or $0.17 per share (basic and diluted), compared to net loss of $9.0 million, or $0.20 per share (basic and diluted), for the same quarter a year ago. The increase is principally attributable to the $22.6 million increase in operating income.

EBITDA for the first quarter of 2012 was $51.5 million, compared to $27.2 million in the same quarter last year. The reconciliation of GAAP net cash provided by operating activities to EBITDA and additional cash flows information is set forth below.

As of March 31, 2012, cash, cash equivalents and marketable securities were $100.3 million. In addition, as of March 31, 2012, the company has available committed lines of credit with commercial banks aggregating $420.0 million, of which $52.6 million is unused.

On May 8, 2012, 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% of the company’s net income. The dividend will be paid on May 30, 2012 to shareholders of record as of the close of business on May 21, 2012. The company expects to pay a dividend of $0.04 per share in the next two quarters.

Commenting on the outlook for 2012, Ms. Bronicki said, “We currently expect our 2012 product revenues to be $165 to $175 million. We are maintaining our electricity forecast of $315 to $330 million. The wide range is due to the uncertainty around natural gas prices.”

Reconciliation of EBITDA and Additional Cash Flows Information

For the Three-Month Periods Ended March 31, 2012 and 2011

(Unaudited)

We calculate EBITDA as net income before interest, taxes, depreciation and amortization. EBITDA is not a measurement 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 is presented because we believe it is 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 differently than we do. The following table reconciles net cash provided by operating activities to EBITDA for the three-month periods ended March 31, 2012 and 2011:
