In the ever-evolving world of renewable energy, South Australia Power Networks (SAPN) has emerged as a trailblazer with its innovative approach to integrating home solar power. In the previous year, South Australia produced over 70% of its energy from wind and solar sources, often surpassing the demand. While this achievement is a testament to the state's commitment to clean energy, it presents a unique challenge: how to manage excess solar energy without destabilizing the grid.
SAPN's Solution: Flexible Solar Export
To address this challenge, SAPN introduced an ingenious solution—flexible solar exports. This forward-thinking approach allows solar energy system owners to export electricity to the grid at full capacity most of the time, offering a 10kW export limit. However, it dynamically adjusts this limit when necessary to ensure grid stability.
The 400-User Trial
This groundbreaking concept was first tested in a 400-user trial conducted in congested parts of the network. The trial spanned from 2021 to 2023 and culminated in a decision to implement flexible exports for all new installations on SAPN's network. The results were nothing short of remarkable, with participants in the trial enjoying full-capacity solar exports 98% of the time
The Benefits of Flexible Exports
1. Enhanced Grid Stability:SAPN's flexible export system provides an effective mechanism to maintain grid stability even when solar power generation exceeds demand. This is crucial for preventing voltage rises and frequency fluctuations that can disrupt the network.
2. Optimized Energy Usage: Homeowners with solar installations can now make the most of their systems. By allowing full-capacity exports for the majority of the time, SAPN empowers individuals to maximize their energy savings.
3. Encouraging Solar Adoption:The promise of consistently harnessing solar power's full potential makes adopting solar energy even more attractive to homeowners. This incentivizes further investment in renewable energy.
4. Reduction in Emissions: By facilitating the smooth integration of excess renewable energy into the grid, flexible exports contribute to a significant reduction in carbon emissions, aligning with Australia's and the world's climate goals.
By increasing customer solar exports, SAPN's executive general manager of innovation and technology, Chris Ford, explained that the implementation of IoT-driven flexible solar exports has significantly increased the availability of low-cost renewable energy for the distributor's customers. The beauty of this system lies in its adaptability – it allows homeowners to export more solar energy to the grid when the network can accommodate it, ultimately driving down energy costs and reducing carbon footprints.
Enhancing Network Visibility and Planning
Beyond the customer benefits, SAPN's IoT solution offers a comprehensive view deep into the network. This increased visibility allows for quicker problem resolution and more efficient network planning. With the ability to monitor and manage customer inverters, SAPN can identify potential issues in real-time, optimizing the energy grid's overall performance.
Future Outlook: Regulations and Expansion
As South Australia takes the lead in flexible solar exports, it's worth noting that similar innovations are on the horizon for the entire National Electricity Market (NEM) in Australia. The Australian Energy Regulator (AER) has been actively working on regulations to govern flexible exports, as indicated by their "final response" following a consultation in 2022. These regulations are expected to create a framework for implementing IoT-driven solutions like SAPN's across the NEM, further solidifying Australia's commitment to clean, sustainable energy.
Where Flexible Exports Is Available
Initially launched in select areas, Flexible Exports is available to residents in the City of Mitcham and the City of Onkaparinga. Additionally, several suburbs now have the privilege of enjoying this program, including Brighton, Largs North, Oaklands Park, and many others in the list below:
- • Dover Gardens
- • Glenelg South
- • Glengowrie
- • Hallett Cove
- • Hove
- • Marion
- • Mitchel Park
- • North Brighton
- • North Haven
- • Sheidow Park
- • Osborne
- • Outer Harbor
- • Park Holme
- • Seacombe Gardens
- • Taperoo
- • Torrens Island
- • Trott Park
- • Warradale
The good news doesn't stop there. SAPN is committed to expanding the reach of Flexible Exports, with plans to introduce this program to more suburbs in new council areas in the coming months. By mid-2024, SAPN aims to make the Flexible Exports option available in most suburbs across South Australia, ensuring that a larger portion of the population can benefit from this initiative. Customers in eligible areas can opt into Flexible Exports when it becomes available in their suburbs, opening up new opportunities for them to manage their energy usage effectively and embrace solar power.
No Changes for Existing Solar Customers
For existing solar customers under SAPN, it's important to note that there will be no change to your current arrangement. This new offering is primarily aimed at new and upgrading customers, allowing them to access the advantages of Flexible Exports from the outset.
South Australia has embarked on a bold journey towards a more flexible and sustainable energy future with the introduction of new regulations set to take effect on July 1, 2023. These regulations, spearheaded by the Government of South Australia, mandate that all new exporting generation systems must be equipped with the capability to remotely update their export limits. The central objective is to ensure compatibility with SA Power Networks' cutting-edge Flexible Exports program, revolutionizing the way energy is harnessed and distributed.
The Two Faces of Export Limits: Fixed and Flexible
Within this transformative landscape, two distinct export limit options emerge, each catering to unique energy needs and grid dynamics.
Fixed Export Limit: This option offers a consistent and unchanging export limit of 1.5kW per phase throughout the year. A permanent and reliable choice, it provides a steady stream of energy, irrespective of fluctuations in the grid's capacity or demands.
Flexible Export Limit: his option harnesses the power of compatible, smart, and internet-connected inverters. These advanced devices receive regular updates from SA Power Networks, allowing them to synchronize exports with the available grid capacity. The result is a dynamic export limit that can automatically adjust within a range of 1.5kW up to an impressive 10kW per phase. The extent of this adjustment is subject to various factors, including network capacity, the customer's location, installed inverter capacity, and the reliability of the customer's internet connection.
The Flexible Exports option represents an innovative approach to utilizing rooftop solar technology in South Australia. It's a world-first smart solar solution that offers numerous benefits to solar system owners and the overall energy grid. Here's what the Flexible Exports option entails.
Savvy Savings: By opting for the Flexible Exports option, solar system owners can enjoy direct savings on their energy bills. This means that they can maximize the financial benefits of their solar installations by efficiently exporting excess energy back to the grid.
Grid Stability:The Flexible Exports option contributes to keeping the energy grid healthy and less prone to outages. By allowing for a more controlled and adaptive export of solar energy, it reduces the risk of grid instability and enhances the overall reliability of the energy infrastructure.
Renewable Energy Optimization:With the Flexible Exports option, more renewable energy is harnessed with less waste. It enables solar system owners to make the most of their solar resources by adjusting the amount of energy they export based on the grid's capacity, ensuring that excess energy is not wasted.
Lower Energy Costs:As more people opt into Flexible Exports, the increased availability of solar energy in the grid may lead to cheaper electricity for everyone. This means that not only do individual solar system owners benefit, but the broader community may also enjoy cost savings on their energy bills.
Higher Export Capacity:The Flexible Exports option relies on an internet-connected inverter that allows solar system owners to export up to 10kW back to the grid per phase. This significant export capacity brings South Australia closer to its goal of doubling the energy generated from solar sources
