(2) The distribution system operator's technical dispatching system shall limit the power output of power generating facilities connected with the negative power to a maximum power level supplied from the power plant to the distribution system and, cumulatively, up to the agreed amount and, if not agreed, the maximum available sum values for the restriction of electricity production using the negative power.
(3) The distribution system operator's technical dispatching system shall divide the size of the required power limitation to be supplied to the distribution system between power plants connected with the negative power according to current or anticipated operating conditions and, as appropriate, the power limitation of which power plant connected with the negative power will best contribute to preventing or addressing congestion in the distribution system.
(4) The power producer shall limit the power of the power plant connected to the negative power according to the operational instructions of the distribution system operator to a maximum of:
(a) the determined value of the power of the power plant connected with the negative power in the smooth way of regulating the power of the power plant connected with the negative power; or
(b) a specified or nearest lower value from the specified power value in the step-by-step way of regulating the power of the power plant connected to the negative power.
(5) The operational instruction to limit the performance of the power plant connected with the negative power supplied to the distribution system shall be issued by the technical dispatching of the distribution system operator for the period foreseen to prevent or manage congestion in the distribution system.
(6) If the power-generating facility manufacturer fails to comply with an operational instruction to limit the power of the power-generating facility connected to the negative power within 1 minute for non-synchronous power-generating modules or within 5 minutes for synchronous power-generating modules, the technical dispatching of the distribution system operator shall invite the power-generating facility manufacturer to immediately reduce the power-generating facility connected to the negative power within the scope of the operational instruction issued. If the power producer does not limit the power of the power plant connected with the negative power, within 5 minutes of the receipt of the call for immediate restriction of the power plant connected with the negative power referred to in paragraph 1, and if there is still a need to resolve the congestion in the distribution system, the distribution system operator shall change or interrupt the supply of electricity from the power plant connected with the negative power pursuant to Article 25 (3) (d) of the Energy Act.
(7) The regional distribution system operator's technical dispatching system shall inform the TSO of the restriction on the power output of power generating facilities connected with the negative power of the transmission system operator's technical dispatching system if the power limitation exceeds 50 MW beyond its managed distribution system.
(8) The TSO's technical dispatching system shall inform the connected local distribution system operator of the restriction on the power output of power generating facilities connected with the negative power of the regional distribution system operator if the power limitation exceeds 10% of the reserved power at the local distribution system connection point.

(4) The distribution system operator's technical dispatching system for any restriction on the supply of power from a power plant connected with the negative power shall determine the amount of electricity not delivered to the distribution system as a product
(a) the difference in power supplied to the distribution system at the time of the required start of the restriction on the performance of the power generating facility connected with the negative power and the required value, to which the power generating facility connected with the negative power should have been limited in accordance with the operational instruction; and
(b) the duration of the restriction on the performance of a power-generating facility connected to a negative power-generating facility, as determined by the technical dispatcher of the distribution system operator, but not more than the period for which the power-generating facility connected to the negative power-generating facility has restricted the power-generating facility's performance under the operational instruction.
(5) Where the distribution system operator's technical dispatching system has access to the instantaneous data from the distribution system operator of the specified systems installed on power generating plants connected with a negative power using solar energy or wind energy to determine the amount of non-delivered electricity on the basis of measurements of oscillation, wind speed or temperature in accordance with point 5 (b). (b) Annex 6 to this Decree or, if it is possible to determine the intended performance of these power plants from another similar system, the amount of electricity not delivered to the distribution system shall be determined as the sum of the products
