Negotiated transmission service criteria
By virtue of clause 11.98.8 of the NER, the provisions for negotiated transmission services in version 109 of the NER continue to apply in Victoria. This means that as part of our transmission determination for Basslink we must make a decision on the Negotiated Transmission Service Criteria (NTSC) to be applied by Basslink in negotiating terms and conditions of access for its negotiated transmission services.
Our proposed NTSC for Basslink are available below. Submissions on the proposed NTSC together with submissions on Basslink's proposal, closed 16 February 2024.
