• Trial Run period started with ENTSO-E on 18th of September 2010.

• The first phase system stability tests approved by

ENTSO-E Planary Group on 8th of February.

• Without any trade Import-Export tests for the second phase found successfull by ENTSO-E.

• The third phase (import-export with trade) related with the synchronous parallel operation of Turkey with European Power System started on 1th of June 2011 and it will be ended on September 2012.

• Trade will be limited with 400 MW from Bulgaria and Greece to Turkey; 300 MW from Turkey to Europe via these countries.

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.

• Process:

1. The available capacity of substations for connecting wind powerplants are published by TEİAS.

2. WPP applications are forwarded to TEIAS for studying connection opportunities.

3. TEIAS gives its comment concerning the availability.If the application is alone in the substation, EMRA gives license to those applications.

4. If there are multiple applications in one substation, compitition process is done by TEIAS to determine the owner of the capacity.

5. After taking license the investor sign a connection agreement with TEIAS.

6. 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

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 is3000x5/100 = 150 MW

- New regulation which will be published in the near future, IEC 61400 standarts are applied to determine available wind power capacity

AVAILABLE WIND POWER CAPACITY CAN BE CONNECTED TO THE BUSBARS?
