(v) the unserved energy to load that is interrupted by a single asset failure is not to be capable of exceeding 3 000 MW.h at any time;
(b) in respect of a transmission system that is not an intact transmission system, the active energy exposed to interruption by a credible contingency event is not to be capable of exceeding 18 000 MW.h at any time.
(2)  The network performance requirements under subregulation (1) constitute the service standards that a Provider must take into account, for the purposes of the regulatory investment test for transmission, in carrying out power system planning in respect of a relevant transmission system.
(3)  For the purpose of meeting the requirements under subregulation (1) , a Provider may use load shedding –
(a) to control network load after a non-credible contingency event; or
(b) as specified in a contract, agreement or arrangement entered into by the Provider and a Transmission Customer.
(4)  For the purpose of calculating unserved energy under subregulation (1) , any replacements or repairs undertaken must be taken to not exceed –
