Geothermal Plant Makes Its Electricity Even Greener
As Turkey pushes to meet 30% of total electricity demand through renewable energy by 2023, it is growing capacity across all renewable sources, including geothermal. The country’s Energy Market Regulatory Authority estimates that the country has 45 gigawatts (GW) of hydropower potential, 48 GW of wind energy potential and 600 megawatts (MW) of geothermal energy potential. Currently, Turkey’s geothermal capacity is approximately 200 MW.
One company working hard to exploit the natural resources of Turkey, particularly its geothermal energy potential is Maren Enerji, which recently expanded three existing geothermal energy plants to a total installed capacity of 68 MW, while building a fourth plant that will add another 24 MW. In total, the four plants located in Aydin, south of Izmir in the west of the country, will provide 92 MW of electricity, enough to power more than 100,000 Turkish homes.
Although a renewable energy source, geothermal does have an environmental footprint and GE technologies are helping the plant not only shrink its impact on the environment, but also save money. Not only do the GE solutions save Maren Enerji $500,000 a year, they also have significantly reduced water usage, lowered CO2 emissions and decreased corrosion across the plant’s underground piping networks, which are some of the world’s longest.
By using GE’s InSight Knowledge Management Solution, a remote monitoring and diagnostic platform, the plants can monitor their water treatment systems. The web-based platform also helps maximize operational reliability through real-time visualization and diagnostics related to keeping the water systems’ performance and parameters on track.
GE also provided an automatic chemical solution preparation unit, as well as an environmentally friendly solution to reduce water consumption – vital in a region that is experiencing a shortage of agricultural-quality water. The automatic preparation and the piping networks mean that Maren Enerji no longer needs to truck chemicals through the agricultural region where the plants are located, thereby eliminating dust and lowering CO2 emissions caused by the trucks.
GE recently honored Kipaş Holding, which owns Maren Enerji, with the Return on Environment award in recognition of the company’s noteworthy reductions in water usage, lowered CO2 emissions and decreased corrosion.
