Canberra’s Power Grid: Preparing for a Surge in Demand and a Changing Climate
Imagine a Canberra winter where increasingly frequent power outages disrupt daily life, not just for a few, but across rapidly growing suburbs. This isn’t a dystopian future, but a potential reality highlighted by recent data showing record electricity demand alongside a 20% jump in outages in the ACT this past June. As Canberrans embrace electric appliances and the population swells, the pressure on Evoenergy’s network is intensifying, demanding a proactive and innovative approach to energy infrastructure.
The Electrification Equation: More Homes, More Demand, Fewer Gas Connections
The ACT is undergoing a significant energy transition. Driven by ambitious climate goals and a growing preference for electric alternatives, over 5000 households disconnected from gas in 2023 alone. This shift, coupled with a population increase of 6838 residents and 3900 new dwellings last year, is placing unprecedented strain on the electricity network. The impact isn’t evenly distributed; Gungahlin and the Molonglo Valley, the fastest-growing areas, are bearing the brunt of the increased demand. Evoenergy acknowledges that aging infrastructure in these areas is contributing to the problem, requiring substantial upgrades to meet current and future needs.
“This increase coincided with colder-than-average minimum temperatures and record electricity demand in the ACT, driven by winter heating, population growth and electrification,” a spokesperson for Evoenergy explained. The colder temperatures – June 2025 saw the coldest average overnight temperatures in 41 years – further exacerbated the situation, pushing demand to all-time highs.
The Role of Rooftop Solar: A Partial Solution
While demand is rising, the ACT isn’t facing this challenge unprepared. The government projects a 21% increase in grid demand by 2045, but anticipates that rooftop solar will offset 26% of that increase. This highlights the crucial role of distributed energy resources in mitigating the strain on the central grid. However, relying solely on rooftop solar isn’t enough. The intermittency of solar power necessitates robust grid infrastructure and energy storage solutions to ensure a reliable supply, especially during peak demand periods and extended cold snaps.
Beyond Batteries: Modernizing the Grid for the Future
Evoenergy is actively investing in network upgrades to address the growing demand. The installation of six temporary batteries in Denman Prospect proved vital during June’s peak demand, preventing further outages in the Molonglo Valley. This is a short-term fix, however. A new Molonglo Zone Substation, expected to be completed before next winter, will provide a more permanent solution. Similar upgrades in Gungahlin have already yielded positive results, with a 41% decrease in unplanned outages compared to the previous financial year.
These targeted upgrades demonstrate a proactive approach, but a more comprehensive modernization of the grid is essential. This includes not only increasing capacity but also implementing smart grid technologies that can optimize energy flow, detect and isolate faults quickly, and integrate distributed energy resources more effectively.
The Potential of Virtual Power Plants (VPPs)
One promising avenue for future grid stability lies in the development of Virtual Power Plants (VPPs). VPPs aggregate distributed energy resources – like rooftop solar, batteries, and even controllable appliances – into a single, coordinated system. This allows Evoenergy to tap into a flexible pool of energy resources, reducing reliance on traditional power plants and enhancing grid resilience. See our guide on Smart Grid Technologies for more information.
The Long-Term Outlook: Resilience in a Changing Climate
The challenges facing the ACT’s electricity network are not unique. Across Australia, and globally, grids are grappling with increasing demand, the integration of renewable energy, and the impacts of climate change. More frequent and intense extreme weather events – like the recent cold snap – will undoubtedly put further strain on infrastructure.
Evoenergy’s commitment to robust maintenance, proactive planning, and strategic upgrades is commendable. However, a long-term vision that prioritizes grid resilience, embraces innovative technologies like VPPs, and fosters collaboration between energy providers, government, and consumers is crucial. The Australian Energy Regulator’s (AER) Annual Benchmarking Report, which consistently ranks the ACT network among the most reliable in the country, provides a solid foundation for future improvements.
“We have robust maintenance and planning in place, are actively managing the network to meet demand, and are well prepared for the remainder of winter.” – Evoenergy Spokesperson
Key Takeaway:
The ACT’s electricity network is at a critical juncture. Successfully navigating the energy transition and ensuring a reliable power supply for a growing population requires sustained investment, innovative solutions, and a forward-thinking approach to grid modernization.
Frequently Asked Questions
Q: What is Evoenergy doing to prevent future outages?
A: Evoenergy is investing in network upgrades, including new substations and battery storage, as well as implementing proactive maintenance programs to address aging infrastructure and increasing demand.
Q: How can I contribute to grid stability?
A: Installing rooftop solar and a home battery system can help reduce your reliance on the grid and provide energy during peak demand. Participating in demand response programs, where available, can also contribute.
Q: What is a Virtual Power Plant (VPP)?
A: A VPP is a network of distributed energy resources – like solar panels, batteries, and electric vehicles – that are coordinated to operate as a single power source, providing flexibility and resilience to the grid.
Q: Will electricity prices increase as demand rises?
A: Increased demand can put upward pressure on prices. However, investments in renewable energy and grid modernization, along with energy efficiency measures, can help mitigate price increases.
