Pursuant to Article 116 of the Energy Law

4.3.4.3. If the generating unit has the ability to operate in the primary control, it must be 
equipped so as to send the signal to the JSC EMS technical system as regards the status of 
operational participation of the primary control (on, off), and to receive a command signal 
from JSC EMS to turn the primary control on/off.  
4.3.4.4. If the generation unit has the secondary control capability, it has to be able to provide 
JSC EMS technical system with the following additional data: 
- Maximum and minimum power of the power unit when it is in the secondary 
control; 
- Level of power alternation by the impulse of secondary control; 
- Base power of the generator;

- Status of the secondary control device on the generator (on, off); 
- Data required for calculation of the generator share in secondary control. 
4.3.4.5. Generation unit with the secondary control capability must be able to receive the 
following real-time data from JSC EMS: 
- Reference values for regulation (on and off of the secondary control), current 
required power of the secondary control (in the form of reference level or 
regulation impulse); 
- Connection status of the switchgear in the transmission facility connected to the 
generation unit; 
- Current values of the voltage, frequency, active and reactive power flows in the 
transmission facility connected to the generation unit. 
4.3.4.6. Wind generation unit must deliver to the JSC EMS the following additional 
information in real-time: 
- The number of wind generators operating at that moment;
- The number of wind generators that are not operating and the cause (large/small 
wind speed, breakage, repair, etc.). 
4.3.4.7. Wind generation unit must be equipped to deliver to the JSC EMS technical control 
system the following meteorological data in real time: 
- Wind speed at a height where wind generators are installed, in the range of 0-
50 m/s;
- Wind direction;
- Air temperature, from -40 to 60ºC;
- Atmospheric pressure in the range of 735-1060 mbar.
