Active WA VPP programs
Synergy DER Roadmap VPP
Synergy's residential battery VPP. Participates in grid-stability dispatch in coordination with Western Power. Pays a capacity credit plus boosted DEBS export rates during dispatch events.
Horizon Power VPP trials
Horizon Power runs VPP trials in selected regional towns (Carnarvon, Onslow, Esperance among others). Payment structures vary by town and trial.
Notes specific to Western Australia
WA's tightly-regulated retail market means there are fewer retail-led VPP options than in the eastern states. The WA Residential Battery Scheme rebate doesn't require VPP enrolment but the battery must be VPP-capable.
How VPP economics work in WA
VPP earnings depend on two state-specific factors: wholesale electricity price volatility, and grid stress frequency. WA has moderate wholesale volatility, so VPP earnings sit between the highly-volatile SA market and the more stable TAS market.
Should you enrol in a WA VPP?
Two questions help decide:
- Is your battery 10 kWh or larger? Smaller batteries don't generate enough dispatchable capacity for VPP economics to make sense.
- Are you home in the evening (5pm–9pm)? If you discharge the battery yourself during peak hours anyway, VPP enrolment displaces that discharge to grid export — net economically positive only if the per-event payment beats the difference between your import and feed-in rates.
For most WA households with a 10–13.5 kWh battery and average evening usage, VPP enrolment adds $300–$900/yr to total solar income. We'll model the exact number for your address when we get in touch.
Common questions
What VPP programs are available in Western Australia?
WA currently has 2 active residential VPP programs: Synergy DER Roadmap VPP (Synergy / Western Power), Horizon Power VPP trials (Horizon Power (regulated)). Each has different payment models and battery brand compatibility — check the details below.
How much can I earn from a VPP in Western Australia?
In WA, typical residential VPP earnings sit between $300 and $900 per year, depending on programme and battery size. Households on wholesale-pegged plans (like Amber) can earn more — sometimes $1,500+ — but with variable monthly returns.
Do I need to switch retailers to join a VPP in WA?
WA's regulated retail market means you don't have a choice of retailer — Synergy and Horizon are the only options depending on your network. Their VPP programs are open to existing customers.
Does WA require VPP enrolment for the federal battery rebate?
No. The federal Cheaper Home Batteries Program requires your battery to be VPP-capable — meaning it can support enrolment — but actual enrolment is optional. You can claim the rebate and never join a VPP.
