CHAPTER 2: GLOSSARY 
2.1.
 
TERMS 
2.1.1. The terms used in the Grid Code have the meanings defined by energy sector 
regulations, with the exception of: 
A
CTIVE POWER 
– Real part of conjugated complex product of voltage and current. This is the 
component of power that performs the desired operation on the consumption side. 
A
LLOCATED CAPACITY 
– The total capacity appropriately allocated to participants in the 
electricity market by the transmission system operator.
A
REA CONTROL ERROR
– Current difference between the actual and planned values of power 
exchange within the control area, corrected for the value of a frequency member of that 
control area (control constant of the given control area multiplied by frequency deviation). 
A
UTOMATIC GENERATION CONTROL 
– The process of automatic control of power generation 
(active power) in regulation power plants, so that the frequency and sum of electric power 
exchange with the neighboring power systems is maintained as close to the planned values as 
possible.
A
VAILABLE TRANSMISSION CAPACITY 
–
The difference in net transmission capacity and 
transmission capacity allocated to participants in the electricity market.
A
VAILABILITY
– The state in which the generating unit, transmission element or another 
element of the power system is able to perform the intended function, regardless of whether 
actually used or not.
B
ALANCE ENTITY
is: 
a) a group of generating units - within one or more production facilities; 
b) generating unit - which is the single generator within the production facility; 
c) controlled consumption – which represents reversible hydroelectric power plant 
or pumped-storage facility while working in the pump mode, or the facility of 
the end user who can regulate consumption upon the request of the transmission 
system operator.
B
ALANCE GROUP
– Virtual area that can receive electricity, or from which electricity can be 
delivered, which is used for the purpose of billing and financial settlement from the aspect of 
balance responsibility. It includes a set of accounting points in the transmission, or 
distributive system, as well as receipt and delivery of energy on the basis of blocks of cross-
border and internal power exchange of individual market participants. 
B
ALANCE RESPONSIBLE PARTY 
–
