The Complete Guide to Solar Batteries and VPPs in WA

If you've got solar panels on your roof but no battery, you're likely sending valuable energy back to the grid for very little return. A residential solar battery changes that, storing your excess energy and giving you more control over your power bills.

When you connect that battery to a Virtual Power Plant (VPP), you can also earn rewards while helping stabilise the electricity grid. Plico helps WA homeowners do exactly that, with trusted battery brands and an independent VPP built for Australian homes.

What is a Solar Battery and How does it work?

A solar battery stores the excess electricity your panels generate during the day. Instead of exporting that energy to the grid at a low feed-in tariff, your battery holds it for use in the evening or during peak periods.

This means you buy less electricity from the grid and make better use of the clean energy your panels already produce. Most modern batteries, including the AlphaESS, Sigenergy SigenStor, and FoxESS systems offered by Plico, include a hybrid inverter that converts stored DC power into usable AC power for your home.

What is a Virtual Power Plant?

A Virtual Power Plant (VPP) connects hundreds or thousands of household batteries into a single, coordinated network. According to the Clean Energy Regulator, VPPs allow households to actively support grid reliability. When the grid needs extra support, the VPP draws excess stored energy from each connected home and delivers it where it's needed — directly to the grid network.

In return, participating households earn VPP Rewards. You're not just cutting your own bills; you're contributing to a cleaner, more stable electricity grid for your community. Plico operates the only independent VPP in WA, connecting more than 6,000 members across the state.

Battery Brands that connect to the Plico VPP

Plico offers three trusted battery brands designed for VPP participation. AlphaESS is the "Best Value" option, delivering reliable performance, essential blackout protection and strong everyday savings. FoxESS is the latest addition, featuring modular, scalable storage and a compact design built for Australian conditions.

Sigenergy SigenStor sits in the "Full Feature" range, bringing AI-driven energy management, whole-house backup via the optional Sigen Gateway, and integrated EV charging. All three brands include real-time monitoring apps and are VPP-ready from day one. Plico's accredited installers handle everything from system design to VPP enrolment.

Households can sign up through Plico and have a solar + battery solution installation that is connected to the VPP. Or households can bring their own eligible battery to the Plico VPP to start earning VPP rewards. 

How VPP participation reduces your energy bills

VPP members earn credits when stored energy is dispatched during grid events. WA participants on the Plico VPP receive a minimum of 99c/kWh for exported energy during VPP events, which is three times the standard electricity rate.

On top of that, Plico offers a $1,500 VPP Discount on eligible battery systems, reducing your upfront cost. Combined with the WA Battery Rebate and the no-interest loan of up to $10,000, a solar battery becomes a genuinely achievable investment for most WA households.

What to consider before joining a VPP

Before signing up, it helps to think about a few things. Your battery capacity should match your household's energy usage, so you have enough stored power for your own needs before any VPP dispatch. Homes with higher daytime solar generation and lower evening consumption tend to benefit most, as they will generate more VPP Rewards. However, even evening energy users can benefit when their excess energy is dispatched to the grid during VPP events. 

You'll also want a battery brand that's technically compatible with the VPP platform. All three brands available through Plico, AlphaESS, Sigenergy and FoxESS, plus Redback Technologies systems, are designed with VPP integration in mind. Plico manages the setup, so there's no technical heavy lifting on your end.

Solar batteries and VPPs: A smarter way to Power Your Home

Connecting a solar battery to a VPP is one of the smartest moves a WA homeowner can make. You store more of your own solar energy, earn rewards for supporting the grid, and reduce your reliance on fossil-fuel generation.

Plico makes the entire process simple with flexible finance, trusted battery brands like AlphaESS, Sigenergy and FoxESS, and a proven VPP that's been operating for years. Plus, the Plico VPP will help you unlock rebates and loans under the WA Residential Battery Scheme. You have nothign to lose and everythign to gain when you join the Plico VPP!
