Commercial batteries for NSW business, industry and farms

Build the battery case from your site’s real load profile.

GRIDHUB assesses bills, interval data, demand charges, operating hours, solar generation and planned expansion before recommending a commercial battery pathway.

What the system must achieve

A commercial battery should solve a measurable energy problem.

The value depends on when and how the site uses electricity—not simply the battery’s headline capacity.

Operational value

Manage energy and demand

  • Reduce expensive and repeatable demand peaks
  • Capture more onsite solar for later use
  • Shift consumption between tariff periods
Future planning

Support resilience and growth

  • Plan backup and operational priorities
  • Prepare for EV charging or equipment expansion
  • Coordinate controls, monitoring and connection requirements
NSW PDRS pathways

BESS4 and BESS5 commenced on 1 September 2026.

Certificate support is not a fixed rebate percentage. Quantities and value depend on the approved method, equipment data, network factors, project configuration, installation date and certificate market price.

BESS4

Small and medium business batteries

More than 20 kWh to 200 kWh

For qualifying non-residential systems that meet the detailed equipment, installation and scheme requirements.

BESS5

Commercial and industrial batteries

More than 200 kWh to 30 MWh

For qualifying commercial and industrial systems, with incentives applying only to the first 10 MWh, subject to the detailed requirements.

Data centres are excluded from BESS4 and BESS5 under the published NSW position. Site classification and all other requirements must be confirmed before relying on an incentive.
GRIDHUB assessment process

From interval data to a practical delivery plan.

STEP 01

Collect evidence

Bills, interval data, tariff, hours, major loads, solar and planned expansion.

STEP 02

Model value

Test demand reduction, load shifting, solar capture, cycling and resilience.

STEP 03

Check pathway

Confirm likely activity, site, equipment, installer, network and planning rules.

STEP 04

Engineer delivery

Finalise protection, connection, controls, testing, installation and monitoring.

Primary-production farms can be assessed.

Irrigation, pumping, refrigeration, processing, sheds, solar generation and operating seasons can materially affect the battery’s size and value.

Good questions

Before you invest in commercial storage.

Is BESS support a guaranteed 20%–50% rebate?

No. BESS4 and BESS5 create certificates using prescribed calculations; they are not universal fixed-percentage rebates. Online figures are examples until the specific project is assessed.

What information should we provide first?

Start with recent electricity bills and, where possible, 12 months of interval data. Include operating hours, existing solar, major loads, planned EV charging or expansion and resilience requirements.

Is the largest battery usually best?

No. Capacity and inverter output should be matched to the load profile, solar, demand peaks, cycling opportunity, connection constraints and the business objective.
