Grid Optimisation & VPP

Turn your battery into an income asset.

VPP revenue, FCAS participation, energy arbitrage and bill tendering — fully managed by Zool Energy under one Total Care contract.

The hidden market

You’re missing thousands in energy market income.

The Australian energy market is worth $15 billion+ every year, but most businesses only participate as price-takers buying expensive retail electricity. The insiders earning real income from grid services and wholesale purchasing already play on the other side of the table.

The Zool Energy strategy

Two moves that unlock the market.

Most businesses leave money on both sides of the meter. Zool Energy works both — selling services into the grid, and negotiating wholesale rates on the way in.

Part 1 · Sell into the grid

Virtual Power Plant revenue

Your solar and battery stop being cost centres and start earning. Smart inverters join FCAS markets, arbitrage off-peak vs peak pricing, and respond to grid events — automatically, 24/7, with no operational burden on your team.

Part 2 · Negotiate on the way in

Competitive bill tendering

Stop paying retail rates for wholesale energy. Zool Energy runs a competitive tender across 10+ retailers, secures wholesale-linked pricing, and audits 24 months of past bills to recover overcharges and missed rebates.

Three revenue streams

Your energy assets working 24/7 to generate income.

Solar and battery sit idle most of the day. Our algorithms put them to work across three energy markets, dispatching automatically whenever conditions favour you.

01

FCAS markets

Your battery helps stabilise grid frequency, responding to second-by-second demand swings. AEMO pays for every dispatch event — plus availability just for being online.

  • Regulation services$100–$300 / MW/hr
  • Contingency services$200–$800 / MW/hr
  • Availability paymentsEarn while online
02

Energy arbitrage

Smart algorithms buy electricity when wholesale prices are low and dispatch when they spike. The pattern is predictable enough that the spread becomes a reliable monthly line.

  • Off-peak buy price$0.10–$0.15 / kWh
  • Evening peak sell$0.40–$0.80+ / kWh
  • Weekend optimisationHigher VPP rates
03

Network services

Grid operators pay you to ease network pressure — reducing consumption during stress events, providing voltage support, or stepping in during emergencies, at premium rates.

  • Peak shavingReduce, get paid
  • Voltage supportReactive rebates
  • Emergency responsePremium event rates
Bill tendering & procurement

Stop paying retail rates for wholesale energy.

Most businesses accept whatever rate their retailer offers — typically 30–50% above wholesale. Large industrial users tender, and have for decades. We bring that same playbook to your business.

What most businesses pay — retailUp to 50% more

That gap — 30–50% above wholesale — is exactly what competitive tendering claws back.

Bill auditing & recovery

  • Tariff misclassification — average $8,000+ recovery, often retroactive.
  • Network fee overcharges — common in retail bundling, hidden in line items.
  • Missed rebates — LGCs, solar credits and concessions left unclaimed.
  • Billing errors — meter mis-reads and calculation faults across cycles.
