INCENTIVES FOR RENEWABLE POWER PLANTS
The Turkey’s Parliament approved a new law 29 December 2010, on regulating the renewable
energy resources market in Turkey. The incentives which are applied for Renewable Power
Plants with the new law guarantees a price of:
•
•
•
•
•
•
•
•
7.3 U.S. cents per kWh for wind energy and hydroelectric power,
10.5 US cents for geothermal energy and
13.3 US cents for energy from waste products and solar energy
These prices will cover energy firms that are established between May 13, 2005 and Dec.
31, 2015.
For energy purchases from companies founded later than Dec. 31, 2015, new prices defined
by the Cabinet will be implemented. The prices for the new companies will not exceed the
current figures, the law said.
In the event that operators use local equipment and technology in renewables energy
facilities, an additional support of 0.4 cents to 2.4 $ per kw will be provided for a five year
term to companies that started producing energy before the end of 2015.
The surplus generation from the renewables will be bought by the distribution companies for
ten years guarantee with the defined energy prices.
The law limits the total production of licensed solar energy with 600 MW until the year of 31
December 2013 and authorizes the cabinet to determine the limits afterwards.

4.
5.
6.
The available capacity of substations for connecting wind powerplants
are published by TEİAS.
WPP applications are forwarded to TEIAS for studying connection
opportunities.
TEIAS gives its comment concerning the availability.If the application
is alone in the substation, EMRA gives license to those applications.
If there are multiple applications in one substation, compitition process
is done by TEIAS to determine the owner of the capacity.
After taking license the investor sign a connection agreement with
TEIAS.
Project will be approved by MENR. After the realization of the project
System Usage Agreement will be signed by TEIAS.

Future Problems
• What will be the operation problems if ~11000 MW wind power plant will be
in service ?
• Wind applications are concentrated in west side of Turkey. This will cause
excessive voltage changes in the region
• Effective regional voltage control ;
• Effective secondary reserve control
• Effective ENTSO-E interconnection tie line control will be needed
• All these issues can be managed by an effective wind forecast and
monitoring system

AVAILABLE WIND POWER CAPACITY CAN BE CONNECTED TO THE BUSBARS?
According to the Transmission System Supply
Reliability And Quality Regulation in the third section
Generation Connection Principles - Design Principles of
Generation
Facility
Switchyards
defined
that
“Connection of generation facility based on wind energy
is permitted for a capacity up to 5 % of the system short
circuit power at the connection point ”
For example, A substation, minumum3 ϕ Short
Circuit Power is
Sk=3000 MVA
Available wind power capacity for this busbar is
3000x5/100 = 150 MW
- New regulation which will be published in
the near future, IEC 61400 standarts are
applied to determine available wind power
capacity
