How a 1,000 kWh BESS Can Reduce C&I Energy Costs using the NEW PDRS Rebates
For commercial and industrial (C&I) businesses in NSW, battery storage is becoming an important tool for reducing electricity costs, managing peak demand and maximising the value of onsite solar.
A 1,000 kWh WEnergy Systems BESS can combine these benefits while potentially providing access to incentives under the NSW Peak Demand Reduction Scheme (PDRS).
What is the PDRS?
The NSW PDRS encourages investment in technologies that reduce electricity demand during peak periods. Eligible battery projects can generate Peak Reduction Certificates (PRCs), which have a market value and can provide an upfront financial benefit.
The value is not simply based on battery size. Eligibility and PRC calculations depend on the battery configuration, site demand profile, operating strategy and current PDRS requirements.
For eligible projects, this can provide two key financial benefits:
- Potential PDRS incentive through PRCs
- Ongoing savings from intelligent battery operation
BESS 4 and BESS 5
BESS 4 and BESS 5 are PDRS activities relevant to battery energy storage projects. The applicable activity depends on the characteristics and configuration of the installation.
For C&I customers, the battery should be designed around the site’s electricity consumption, demand profile, solar generation and operating requirements rather than simply selecting a battery based on capacity.
How a 1,000 kWh WEnergy BESS Can Save Money
1. Reduce Peak Demand
A BESS can discharge when site demand is at its highest, reducing the amount of electricity drawn from the grid.
For example:
Site demand: 700 kW
Battery discharge: 400 kW
Grid demand: approximately 300 kW
This peak-shaving capability can be particularly valuable for shopping centres, clubs, manufacturing facilities, warehouses, hospitals and EV charging sites.
2. Store Excess Solar
A solar system can produce more electricity than the site needs during the middle of the day. Rather than exporting this energy at a lower value, the BESS can store it for use later.
This increases the percentage of solar energy consumed onsite and improves the overall return from the solar investment.
3. Energy Arbitrage
The battery can charge when electricity is cheaper and discharge when electricity prices are higher.
An Energy Management System (EMS) can optimise battery operation based on:
- Electricity prices
- Solar generation
- Site demand
- Battery state of charge
- Peak demand thresholds
4. Support EV Charging
A 1,000 kWh BESS can be particularly valuable where high-power EV charging is being installed.
For example, a 240 kW DC charger can create a significant instantaneous load. The battery can supplement the grid supply, potentially reducing the need for additional grid capacity.
This creates an integrated solution:
Solar PV → BESS → EV Charging
5. Improve Energy Resilience
Where specifically designed for backup operation, a BESS can provide energy to critical loads during grid interruptions, helping reduce downtime and protect business operations.
Combining the Benefits
A properly designed project can potentially create value through:
| PDRS / PRCs | Potential upfront incentive |
| Solar self-consumption | Lower grid electricity purchases |
| Peak demand reduction | Lower demand-related costs |
| Energy arbitrage | Shift energy consumption to lower-cost periods |
| EV charging | Support high-power charging while managing demand |
| Energy resilience | Potential backup for critical loads |
A Future-Ready Energy Solution
A 1,000 kWh WEnergy BESS can become the centre of an integrated C&I energy system combining solar PV, battery storage, EV charging and intelligent energy management.
The opportunity is not simply to install a battery. It is to actively manage when electricity is generated, stored and consumed to reduce operating costs and maximise the value of renewable energy.
For NSW businesses, the PDRS may further improve the economics of eligible battery projects.
