The PDRS & BESS: What We Know and What We are Waiting For

The expansion of the NSW Peak Demand Reduction Scheme (PDRS), commencing 1 September 2026, introduces new commercial battery energy storage system (BESS) activities under the Store and Shift Capacity (SASC) method. This update provides commercial and industrial (C&I) solar EPCs with a mechanism to lower upfront capital costs for energy storage installations across residential apartment buildings, small-to-medium businesses, and large commercial industrial sites.

While the opportunity is significant, understanding the operational and regulatory requirements is essential before incorporating these incentives into client proposals. This overview discusses the established parameters of the scheme expansion, the remaining regulatory confirmation from IPART, and practical steps for industry participants.

What We Know

The Activities.

Under the PDRS framework, the expanding SASC method introduces three main activity classifications for commercial battery storage.

Activity	Application	Max. Incentive Value *based on a $2.50 PRC price
BESS1 Single Dwellings & Small Business (Reintroduced)	Covers standard residential single dwellings, small businesses, ONLY in government-owned/managed buildings (typically 2 to 28 kWh capacity).	$5,588
BESS3 Apartment Buildings	Covers battery installations in residential Class 2 apartment buildings with 4 or more dwellings (20 to 200 kWh capacity).	$56,160
BESS4 Small & Medium Businesses	Covers commercial installations for small and medium businesses, excluding residential buildings and data centers (20 to 200 kWh eligible capacity).	$46,800
BESS5 Commercial & Industrial	Covers larger commercial and industrial systems, excluding residential buildings and data centers  (200 kWh up to 30,000 kWh eligible capacity with rebates capped at 10 MWh).	$2,340,000

Key Operational and Compliance Rules.

The technical and administrative requirements for BESS activities include several defined standards:

• September 1 Go-Live
  Eligible battery installations under the new expansion activities – specifically BESS3 (Apartments), BESS4 (SME Commercial), and BESS5 (Large C&I) are eligible starting September 1, or after your ACP is accredited – whichever is later.
• Usable Capacity Standard
  PRC calculations are based on usable battery capacity, set at 90% of nominal capacity or as specified on the CEC approved list.
• Product Eligibility
  Systems under BESS3 and BESS4 require CEC-approved batteries and inverters. While BESS5 systems require safety testing to the UL 9540A standard.
• Audit and Verification Requirements
  Compliance standards require mandatory pre and post installation documentations, geo-tagged photos.

• DNSP Approval Documentation
  Connection Approval documentation will be required to confirm Peak Demand Reduction capabilities at the time of the installation.
  

• Planning Certificate Evidence
  IPART has advised planning certificates adhering to the NSW Environmental Planning Policy to be provided on installations of Solar systems and Batteries under the PDRS scheme. (Mainly for BESS3.4 &5)

What We Are Waiting On

Outstanding Regulatory Clarifications.

Several administrative and regulatory components must be finalised by IPART and the NSW Government prior to full operational execution:

1. IPART Consumer Factsheets
   IPART has not yet published the finalised factsheets. An official PDRS Consumer Factsheet must be delivered to the client during the quoting phase or before installation starts otherwise the job may be considered ineligible.
2. ACP Accreditation and Nomination Forms
   Original Energy Saver (Customer)  must sign a PDRS Nomination Form prior to or on the completion date. At this point, no Accredited Certificate Provider (ACP) has been formally accredited by IPART for these new sub-methods. IPART has further instructed scheme participants that ACPs may not supply, accept, or process nomination forms for activities prior to receiving accreditation. Pre-signed or backdated forms will be invalid.
3. Registration Timing and Site Definitions
   Guidance is pending regarding whether PRC registration for BESS5 claims occurs upon CCEW issuance or following final Distribution Network Service Provider (DNSP) connection approval. Additionally, administrative guidelines regarding multi-NMI and multi-tenant commercial sites require further clarification.

Commercial Guidance for EPCs

To remain compliant during this transition period, we recommend the following do’s and don’ts in incorporating this new information to your company processes:

Do’s

• Inform and train up your sales and technical teams about thresholds and equipment eligibility requirements, such as a cap of 200kWh for BESS4 and UL 9540A product testing for BESS5.
• Explain the current policy as it stands to your customers. 
• Subscribe to our BESS3,4,&5 Mailing list to be updated on the latest developments of the PDRS scheme. 
• Register and create an account with Ecovantage to establish administrative processes ahead of the scheme commencement.

Don’ts

• Do not apply PRCs as an upfront discount on client quotes prior to scheme go-live and accreditation.
• Do not issue, sign, or submit nomination forms prior to formal ACP accreditation.
• Do not commit to fixed forward pricing or market positions on BESS5 claims until final deeming formulas are established.
