Dedicated connection assets

Dedicated connection assets (DCA) are privately owned and operated connection assets that provide the services required to connect a party to the shared transmission network. A DCA connects a party to the shared transmission system at a single connection point and can be isolated from electricity flows on the shared transmission network, e.g. the power line that connects parts of a substation to a generating system.

A DCA is the part of the transmission network that is not a part of the shared network, which is established to provide connection to specific users. They are funded by the specific users rather than under Transmission Use of System charges (TUoS). There are two classes of DCAs, a large DCA (LDCA) is one that is longer than 30km.

The National Electricity Rules (NER) require the AER to publish a register of existing DCAs and AER approved Dedicated Connection Asset Service Provider (DCASP) access policies.

Register

Under clause 11.98.2(b) of the NER, the AER must publish a register of existing DCAs owned, operated or controlled by registered market participants.

Four registrations were received by the 1 May 2018 cut-off date specified in clause 11.98.2(a).

Access policies

Rule 5.2A.8(d) of the NER requires that, within 30 days of an asset being classified as a large DCA under Chapter 2, a DCASP must submit an access policy for approval by the AER.

Rule 5.2A.8(f) of the NER requires that, the AER must approve an access policy, or a variation to an access policy, if it is reasonably satisfied that it complies with paragraph 5.2.8(b) [the minimum requirements]. If the AER does not approve an access policy submitted under paragraph (d), the AER must notify of the changes required for it to be approved. If an access policy is not approved within 6 months of the AER's notification of required changes, the AER may itself propose an access policy.

Below is a list of the access policies approved by the AER:
