GREENECO ENERJI

GreenEco is a subsidiary of Saray Holding, a Turkish Corporation active in several industries (food and agriculture, electronic and mechanical, energy, furniture, packaging and logistics) and a leading brand in Turkey within the confectionary business, well known for its delicious products.

GreenEco Enerji, established in 2012 to meet Turkey’s energy needs by harnessing local renewable resources, sought the best solution to exploit their geothermal resource located in Sarayköy – in the Denizli area.

ORC geothermal power plant

Client name:
GREENECO ENERJI

Plant Location:
SARAYKOY, TURKEY

Date of implementation:
2015 - 2020

Plants size:
12 MWe each (unit 1,2,3,4), 28 MWe (unit 5),
26 MWe (unit 6) 

Total installed capacity:
102 MWe

Application:
GEOTHERMAL

Model Used:
GEX 1200 - 2800 - 2600

Range of resource flow:
1050 - 1400 T/H  

Temperature of Geothermal steam/brine:
130-170 C°

Water or cooling agent:
COOLING WATER (unit 1 and 2) AIR COOLED (unit 3,4,5)

Generator voltage:
6 KV

Installation:
OUTDOOR

In 2014, EXERGY was selected as a supplier of the first two geothermal units, 12 MWe each, commissioned between 2015 and 2016. The completion of this project marked the beginning of fruitful collaboration with Greeneco and, in subsequent years, EXERGY was awarded 4 repeat orders for 4 additional geothermal ORC units. The last power plant was launched in October 2020 with a total capacity exceeding 100 MW delivered to this customer to date. EXERGY designed and proposed tailored solutions for each project to deliver high performance and increased profitability of the power plants. The first two units consist of a water cooled 2 pressure level cycle with 2 Radial Outflow Turbines (high pressure and low pressure) coupled to a single double-ended generator. Unit 3 and 4 feature a 2 pressure level cycle with 2 Radial Outflow Turbines with an air cooled condensing system. In these projects, EXERGY opted for air cooled solutions in order to achieve zero water consumption and decrease the environmental footprint of the power plant.
The last two geothermal units supplied between 2018 and 2020 are the largest projects, consisting of a 28 MWe and 26 MWe ORC system. For the 28 MWe, EXERGY designed a solution with one pressure level cycle, equipped with 2 large turbines of 14 MWe each and employing an air cooled condensing system. The same design was applied to unit 6 for a lower capacity of 26 MWe. With a total installation of 102 MWe in baseload renewable energy capacity for Greeneco, we enabled the customer to reduce its energy consumption and carbon footprint by saving 298,000 tons of CO2 emissions and 153,000 tons of oil equivalent per year.
