ORMAT IN TURKEY
November 17, 2020The month of October has seen a tremendous growth of its geothermal power generation capacity. Ormat Technologies had a great part in this growth!
In October alone we have operated 3 geothermal power plant for our customers and partners. Among the plants are the 3.5 MWe Emirler geothermal power plant, a new business for its owner Halil Pekdemir and the 20 MWe Nezihe Beren geothermal power plant of Maren.
Emirler - The Pekdemir business is in the agriculture market, growing and distributing agriculture products to supermarkets. They also own their own chain.
They are a big agriculture landowner around the Denizli area.
Several years ago, Mr. Pekdemir found geothermal resource in his land. First, he used it to heat and cultivate some of his greenhouse. But with the discovery of a stronger resource in Emirler, we met and worked on a program to develop it for electricity generation too.
On Dec 6th ,2019 we sign the first unit, Emirler JES 1, in a capacity of 3.5 MWe.
We are very proud that with the full support of Pekdemir team, headed by Sinan Akbay, we succeeded to deliver and install the first unit in a record time of less than 11 months.
Now we are planning the continuation- Emirler JES 2 and other areas in the future.Nezihe Beren - Yet another geothermal power plant of Maren, one of Kipas Holding companies.
Maren signed their first geothermal plant in Germencik area (Irem) with Ormat on Feb 11, 2010.
NB was signed on June 20, 2019 for 20 MW gross capacity. It is Maren’s 7th power plant, and with ken 1& 3 and Kiper 1, Kipas hold 10 power plant in total rated gross capacity of 220 MW.
With this power plant, the number of Ormat technology based operating powerplants in Turkey reaches 40, and 3 under construction.

STEAMBOAT HILLS GEOTHERMAL PLANT
November 17, 2020With travel and safety restrictions limiting our geothermal facility tours this year, our business development and marketing teams have come up with a creative solution to show off our newest facility! Check out the 360-degree video of our newest geothermal facility, Steamboat Hills, below. With 360-degree video technology, you can pause the video, move the screen, or tilt your phone to view the plant from any perspective you want. Give it a test drive on your laptop, phone, or tablet device to see geothermal as you’ve never seen it before. (Recommended browser is Chrome, recommended setting of 1080p.)
The Steamboat Hills complex is located in Washoe County, Nevada and is comprised of six power plants utilizing binary systems with both air and water cooling. The generating capacity of the complex is 84 MW, with the first plant reaching commercial operation in 1992, and the most recent plant reaching commercial operation in June of 2020.

WIND GUIDING VANES PATENT
October 1, 2020Wind has a major effect on Air Cooled Condensers thermal performance, thus, on geothermal plants power generation. To regain plant generation during winds, wind effect analysis was performed in Don A Campbell, an Ormat geothermal power plant in Nevada. Wind Guiding Vanes system was developed using computational fluid dynamics (CFD) analysis and optimization process. Field tests were executed on small scale system, including fan flowrate measurements and smoke tests. Results showed a significant performance improvement with the WGV system equipped bays in windy conditions. Following the promising results, full scale solution was implemented in Don A Campbell and is now a commercial patented solution.
Rankine cycle condenser thermal performance determines the turbine back pressure, thus has direct impact on power plant generation, especially in low enthalpy (geothermal heat resource) Organic Rankine Cycle application. Wind has a major effect on Air Cooled/Heated Heat Exchangers in general and Air Cooled Condensers (ACCs) thermal performance in particular. Ambient wind interferes with air flow regime causing reduced airflow, reduced effective heat transfer area and hot air recirculation for induced and forced draft air-cooled heat exchangers.
This paper reviews existing wind effect mitigation methods for air cooled condensers, fundamental analysis of the problem and Ormat designed solution. The conceptual design, considering cost-effectiveness and thermal performance recovery is explained. Experimental system field tests results and full-scale implementation results are presented, as well as yearly power plant generation gain.
