Brief History of Queues

• First WPP commissioned in: 1998• Number of the wind pp’s in operation are: 39 and total capacity: 1320 MW• Current Licensed wind generation: 3483 MW• Date: 1th November 2007 Number of the wind pp’s: 722 Total capacity: 78.000 MW

• According to the system available capacity for connecting wind generation which is equal to 8474 MW a bidding code was prepared by TEIAS which includes the requirements for the applications.

• According to the bidding document the wind owner which will get the right to use the open capacity has to pay an amount to TEIAS for 20 years since connecting to the system which is equal the amount which will be calculated for per kwh generation of the wind power plant.

Recent Situation for Wind Generation in Turkey

• 3483 MW of wind applications has been licensed by EMRA

• 1320 MW is in Operation • 2283 MW is Underconstruction

• 8488 MW is under evaluation

• The amount of the available wind generation capacity can be connected to the system until 2013 is 12000 MW

• In the strategy document it is foreseen that the total wind generation capacity will reach to 20.000 MW until 2023.

9

The available wind generation capacity around 8488 MW is under evaluation

10

Marmara & Thrace Region available wind generation capacity ~ 2745 MW is under evaluation

11

Aegean Region available wind generation capacity around 2499 MW is under evaluation

12

Hatay Region available wind generation capacity around 190 MW is under evaluation

13

Challenges while planning

• Available system reserve

• The required reinforcements for connecting WPP’s into power system.

• The difficulty to guess their production time of wind power plants.

• Who pays the investments and how it will be recovered

• Beside load flow, voltage profile, short-circuit and contingency studies; the %5 of the short circuit power of the substation which WPP will be connected is applied as a restriction criteria in order to keep the overall system security by now.

• Detailed dynamic studies for determining the connection capacities are going on.

INCENTIVES FOR RENEWABLE POWER PLANTSINCENTIVES 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:

• Hydro PPs and WPPs are paid at system marginal price, but minimum 7.3 US$ /MWh is guaranteed

• Geothermal PPs are paid at system marginal price, but minimum 10.5 US$ /MWh is guaranteed

• Biogas PPs and Solar PPs are paid at system marginal price, but minimum 13.3 US$ /MWh is guaranteed

• Those tariffs shall be valid for the PPs which came into service between 18 May 2005 to 31 December 2015 and will be applied for 10 years.

• After 31 December 2015, new tariff shall be given by the Government but the new tariff shall not exceed the tariff above.

15

Queue Management

• Process:

1. The available capacity for connecting wind generations are published by TEİAS.

2. WPP applications are forwarded to EMRA (Turkish Regulatory Agency) for these capacities.

3. These applications are forwarded to TEIAS for studying connection opportunities.

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

5. If there are multiple applications, bidding process is done by TEIAS to determine the owner of the capacity.

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

7. Project will be approved by MENR after the realization of the project System Usage Agreement will be done with TEIAS.

16

Queue Management

• Principle of connection cost sharing in between TSO and investor:

If the investor pays for the connection line then the TSO will pay back to the investor this amount in 10 years from the investment budget.

Otherwise, TSO will put the required investment for the connection of the power plant in it’s yearly investment plan and these procedures takes

approximately 3-5 years for bidding (plus constructing period)

17

Planning Process by TEIAS

• Turkish Electricity Transmission Corporation responsible from the WPP integration studies and to define the available capacity for connecting wind generation

• According to the results of load flow, contingency analyses and short circuit power calculations, the estimation for capacity for each substation and each region which will be available for connecting wind generation are defined by TEIAS

• Concentrated small wind generations in one region are collected in one substation (example: Çeşme Region)

• We have a specific grid code which defines the connection criteria for wind generation but it will be revised for future power system conditions.

Future Efforts

• The wind forecast system has been developed by Turkish State Meteorological Service which is available to provide information about the wind forecasts for different heights and for 48 hours with 4 km. solubility all

around Turkey. The trial tests are going on in order to improve the system.

• Specific monitoring system for wind generation will be installed and the

procedures are going on with consultant company
