Virtual Power Plant (VPP) — Comparison, Pros & Cons


Australia is leading one of the world’s fastest transitions to rooftop solar and home battery storage — and Virtual Power Plants (VPP) have become a major part of that evolution. As more households install batteries to maximise their solar savings, energy retailers and grid operators are increasingly relying on VPPs to stabilise the grid, manage peak demand and make renewable energy more reliable.

For homeowners, VPPs present a new opportunity: instead of letting your battery sit idle, you can get paid for letting a VPP access your stored energy during high-demand or high-price events. But every VPP is different — payment structures, battery control, terms, incentives and real-world performance vary significantly across the Australian market.

This makes understanding how VPPs work, comparing the top providers, and evaluating the pros and cons essential before joining any program.

What Is a Virtual Power Plant (VPP)?

A Virtual Power Plant (VPP) is a network of distributed energy resources—mainly home solar systems, batteries, EV chargers, and smart appliances—that are digitally connected and controlled to operate like a single, coordinated power plant. Instead of relying on one large generator, a VPP uses thousands of small energy systems across homes and businesses to supply power, support the grid, and respond to market conditions.

Here’s how it works in simple terms:

  • You have solar panels that generate electricity during the day.

  • Your battery stores excess solar energy for evening use.

  • When you join a VPP, your battery becomes part of a much bigger aggregated fleet.

  • Advanced software can temporarily draw small amounts of energy from your battery—or adjust its charging—to stabilise the grid during peak demand or emergencies.

  • In return, you receive financial benefits, which may include bill credits, higher feed-in rates, event-based payments, or battery discounts.
