THE BRAIN BEHIND YOUR SAVINGS
Your power. Working together.
The energy management system (EMS) coordinates solar, batteries and grid power around what your business needs.
EXAMPLE · DAYTIME
Solar runs production. Stored power charges your fleet.
Power flowEMS monitoring & control
Almost no grid power needed in this example.
Illustrative operating moment, not a daily result. Actual flows depend on solar output, stored energy and site demand.
ANOTHER EXAMPLE · AN EMS INSTRUCTION“A demand peak is expected in 40 minutes.”
The EMS tells the battery to stop discharging and save power to help cover the peak.
NSW battery incentives
Could incentives reduce
your upfront cost?
We assess BESS4 or BESS5 eligibility alongside your potential electricity savings, before you commit to a system.
What could it be worth?
We assess the potential incentive contribution for your project.
Who handles the evidence?
As an ACP, we plan the required records alongside approvals, design and delivery.
Eligibility and incentive value are project-specific. Approval and a fixed rebate are not guaranteed.
From proposal to switch-on
Who makes it all happen?
One coordinated delivery plan, with the difficult parts addressed early.
Incentive requirements
Build the evidence record as the project progresses.
Grid connection
Plan for your network’s limits, approvals and required testing.
Construction & commissioning
Coordinate installation and make the equipment work as one system.
After installation
Will I know it’s working?
See your system.
Clear monitoring of generation, battery use and system performance.
Understand the results.
Agree how performance is reported and, where included, savings are checked against a defined baseline.
Know who to call.
Defined maintenance, fault response and ongoing service responsibilities.
Monitoring, reporting and service commitments are set out in your proposal.
Real projects. Real delivery experience.
We’ve done the hard parts.
Wollar Solar Farm
346 MWdc · NSW
From early works in 2021 through EPC, grid connection and commissioning to ongoing operations and maintenance.
Project scope & evidence
Sunterra Energy Pty Ltd is the EPC contractor. A three-year O&M agreement includes defined plant-performance requirements. Project-specific commitments do not automatically apply to other sites.
Binduli Hybrid Project
Norton Gold Fields
3 MW solar + 5 MWh battery
Solar, batteries and diesel generation integrated for a working mine. Commissioned in August 2026.
Project scope & context
Joint EPC delivery: Long King supplied equipment; Sunterra’s scope covered design, construction, project management, commissioning and diesel-generator control integration.
Kalgoorlie, WA. An off-grid project; NSW connection and incentive eligibility are assessed separately.

Before you get started
Can I add a battery to existing solar?
We can assess your existing system, electricity use and connection constraints before recommending an addition.
Can my business run independently of the grid?
Solar and storage can reduce grid reliance. Backup and off-grid operation require specific design; they are not automatic battery features.
How much will we save?
That depends on your bill, tariff and load profile. Detailed modelling uses interval data and clear assumptions, rather than a standard percentage promise.
