Consumption Tariffs

As part of our Regulatory Proposal 'Reset' Engagement for 2025-2030, we are holding a series of 'Focussed Conversation' workshops with our stakeholders and customers to engage deeply on priority topics and better understand their current needs and future priorities for electricity.

We commenced our first Focussed Conversation on Tariffs, bringing together several key stakeholders to understand and discuss default network tariff structures, consider the current time of use and demand windows in default network tariff structures, and who and how distribution revenue is recovered from customers.

Workshops 1 to 4 on this topic focus on Consumption Tariffs, while workshops 5 to 8 cover Export Tariffs.

Workshop 1 - Tariff Design and Cost Allocation: Residential

Who did we engage?

The workshop was held on Thursday, 11 August and was attended by 27 stakeholders representing a range of businesses, key industry representatives, governmental organisations and advocates along with SA Power Networks staff members.

What did we engage on?

Participants were asked to consider several questions relating to:

• Endorsement of Default Network Tariff Structures
• What proportion of distribution revenue should be recovered from Residential customers versus Business customers
• What proportion of revenue should be recovered from Fixed charges (daily supply charge) versus Variable charges (usage).

Retailer Tariff Engagement

As part of our consultation process for Reset 2025-30 – Tariffs, we invited all retailers participating in the South Australian market to join us for an online discussion on Wednesday, 30 November. More than 40 representatives from AGL, Alinta Energy, Discover Energy, Energy Australia, Energy Locals, Globird Energy, IO Energy, Momentum, Origin Energy, Red Energy, Shell Energy, Simply Energy, Telstra, YES Energy and Zen Energy joined the meeting.

In the session, we presented the outcomes of our stakeholder consultation so far and sought feedback on our proposed consumption and export tariff structures for the 2025-30 period.

In early December, we also have provided an opportunity for the retailers to meet with us separately to continue the discussion and ask any further questions they may have.
