Power grid operator IPTO has offered a description of its temporary RES grid input-curtailing formula it applies, whenever necessary, to ensure grid stability by preventing overloading during periods of lower electricity demand, for consultation on the matter staged by RAAEY, the Regulatory Authority for Waste, Energy and Water.

Based on the operator’s formula, RES output cuts are currently conducted across the board and proportionately. The operator issues orders for RES grid-injection cuts to individual units, groups of units, as well as to private medium-voltage networks through which green-energy plants are connected to medium and high-voltage substations.

The IPTO formula forwarded for consultation is essentially serving as a transitional framework until a permanent set of rules are established. They are expected to feature criteria prioritizing the order of RES units curtailing their grid injections.

IPTO, according to its formula, is also entitled to issue orders to distribution network operator DEDDIE/HEDNO so that the latter may curtail grid injections at projects linked to the distribution network. The two operators have signed a Memorandum of Understanding concerning this matter.

The IPTO text forwarded for consultation also describes an inspection procedure for RES units as well as a penalty system for units not adhering to curtailment orders.
