As of March 2021 for projects starting generating electricity in Turkey from renewable energy in Turkey in July feed-in-tariffs in lira per kWh are: wind and solar 0.32, hydro 0.4, geothermal 0.54, and various rates for different types of biomass: for all these there is also a bonus of 0.08 per kWh if local components are used.

Relatively efficient gas-fired power stations – such as those based on combined cycle gas turbines – emit about 450 grams (16 oz) of CO 2 per kilowatt-hour of electricity generated. [12] [13] This is about half that of coal-fired power stations but much more than nuclear power plants and renewable energy. [12]
Combined cycle plants have similar capital cost per watt to peaking plants, but run for much longer periods, and use less fuel overall, and hence give cheaper electricity. As of 2020, open cycle gas turbines give an electricity cost of around $151–198/MWh. [2] Peaker plants have been replaced with battery storage in some places. [3]

For power generation applications, the investment costs are cheaper than combined cycle combustion turbine plants (in 2003, the Energy Information Administration estimated that the cost of a combined cycle plant was US$500–550/kW, as opposed to the SCCT cost of US$389/kW [1]), but at reduced efficiency. SCCTs require smaller capital ...
Gas turbines are also more resistant to corrosive damage than RP engines. Gas turbines need a minimum of 1,300 cfm and typically exceed 2,100 cfm and can generate 1 to 10 MW. A gas turbine (greater than 3 MW) can typically cost $1,400 per kW with annual operation and maintenance costs of $130 per kW. [9] Estimates are in 2010 dollars.
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. [1] Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost ...
Plant size is important in the cost of the plant. The larger plant sizes benefit from economies of scale (lower initial cost per kilowatt) and improved efficiency. For large-scale power generation, a typical set would be a 270 MW primary gas turbine coupled to a 130 MW secondary steam turbine, giving a total output of 400 MW.
