2025 Kicks Off with Solar Milestones as Rooftop PV Diminishes Coal’s Grip

Victoria welcomed 2025 with remarkable energy records that highlight the transformative power of rooftop solar PV. These milestones signal a growing shift toward decentralised energy and underscore the increasing impact of solar during holiday periods.

1. Minimum Operational Demand:

1,504 MW at 12:30 PM, breaking the previous record of 1,564 MW (Dec 31, 2023).

A drop of 60 MW (3.8%).

2. Minimum Total Demand:

1,400.1 MW at 12:10 PM, down 3.9% from the previous record of 1,456.4 MW (Dec 31, 2023).

3. Maximum Rooftop PV Share:

Rooftop PV supplied 69.6% of demand at 12:10 PM, surpassing the prior record of 67.8% (Dec 8, 2024).

1. Rooftop Solar’s Growing Role

Rooftop PV's record 69.6% contribution highlights its dominance in Victoria’s energy mix, substantially reducing grid reliance during peak sunlight hours.

2. Evolving Demand Profiles

The increasing output of rooftop solar is “hollowing out” demand, driving operational lows to unprecedented levels and altering traditional energy demand curves.

3. Grid Management Challenges

Managing grid stability amid soaring rooftop PV adoption requires innovative strategies, including expanded storage, dynamic demand response programs, and virtual power plants (VPPs).

4. Collaborative Efforts Needed

The records underscore the need for collaboration among grid operators, policymakers, and consumers to address minimum system load challenges effectively. A coordinated national framework will be key.

These milestones highlight the immense potential of solar energy and the importance of addressing variability and curtailment. Investments in storage, smart grid technologies, and demand flexibility will ensure a stable and efficient energy future.
