and control system other than the anti-islanding protection

that disconnects the generators and/or energy storage from

the distribution system and changes over to a backup

operation mode;

"backup operation mode" means the disconnection

from the distribution system and continuing operation of a

generator or energy storage in the event of the loss of

power from the distribution system with complete effective

isolation from the distribution system while in this mode of

operation;

"Commission Regulation (EU) 2016/631" means

shall be added the following new definition

" "distribution system" shall have the same meaning

as assigned to it in the Electricity Market Regulations;

(c) immediately after the definition "electricity service

meter" there shall be added the following new definitions

" "energy storage" means, in the electricity system,

the deferring of the final use of electricity to a moment later

than when it was generated, or the conversion of electrical

energy into a form of energy which can be stored, the

storing of such energy, and the subsequent reconversion of

such energy into electrical energy or use as another energy

carrier;

"energy storage facility" means, in the electricity

system, a facility where energy storage occurs.";

(d) immediately after the definition "I.E.E. Regulations"

there shall be added the following new definition

at the supply terminals from values declared for normal

supply;

(e) in the definition "Minister", the word "resources"

shall be substituted by the word "energy;" and immediately

thereafter there shall be added the following new definition

which backup equipment shall use hardware that

physically breaks the connection with the

distribution system. Solid state relays or other

semiconductors to break the connection are not

permitted

Provided that the protection of the internal

electrical installation shall remain functional also when

supplied through the generator operating in backup

operation mode.

The anti-islanding protection in all cases shall

automatically disconnect from the distribution system in

the event of loss of supply from the distribution system,

and/or deviation of voltage and/or frequency from normal

supply conditions.

(d) have appropriate signage indicating the

presence on the premises of a generator equipped

with Backup operation mode function.".

6. Immediately after regulation 19 of the principal

regulations, there shall be added the following new regulation

An energy storage facility operated in parallel
