Summary and scope
The Coordinator of Energy has determined, under clause 3.11A.4 of the Wholesale Electricity Market (WEM) Rules, to initiate a Non-Co-optimised Essential System Services (NCESS) procurement process for capacity expansion on the Perth network. Western Power is proactively managing capacity constraints as peak demand continues to rise across the South West Interconnected System (SWIS). Guided by the WA State Government’s DER Roadmap and recent amendments to the Access Code, Western Power has identified a need for solutions through Network Support Services (NSS). Western Power is inviting Expressions of Interest (EOI) from potential NCESS providers to deliver NSS at up to five metropolitan locations within its distribution network. Five distribution feeders have been selected based on Western Power’s assessment of the underlying need, technical requirements, and the potential for a viable non-network solutions. The required services will involve the capability to decrease load during times of supply shortfall. The proposed services are needed during the 2025-26, 2026-27, and 2027-28 summer periods (from 1 December to 1 April), with service quantities based on forecasted shortfalls for each period. Activation of the service will occur between 4:30 PM and 8:30 PM AWST, with NSS being prioritised over other contracted services. The service may be called upon up to 20 times per summer period, with a minimum duration of one hour. Multiple providers may be considered for a single service. The draft NCESS Service Specification provides detailed requirements for these services. While the preferred commencement date for the proposed services is 1 October 2025, with a three-year duration, Western Power is open to feedback regarding potential benefits of alternative contract durations or commencement dates. Queries may be submitted by email to emerging.technology.portfolio@westernpower.com.au or via Q&A function in VendorPanel portal.
