We plan to start a competitive procurement process for five Market Operation Service Provider (MOSP) services shortly. The new contracts are expected to begin from 1 July 2027, though may commence later as necessary to allow transition if new supplier(s) are chosen.
We contract a set of MOSPs to deliver services that help New Zealand’s electricity market operate smoothly. These services are critical for market integrity, settlement accuracy and transparency.
The MOSP services we will be procuring for are:
- Clearing Manager: Acts as the financial counterparty for wholesale electricity transactions, invoicing participants and managing prudential security to mitigate payment default risk.
- Financial Transmission Rights (FTR) Manager: Creates and allocates FTRs through regular auctions, manages the FTR register and supports participants in hedging locational price risk.
- Reconciliation Manager: Processes and reconciles metering data monthly to allocate electricity volumes accurately among participants, ensuring correct settlement and supporting clearing processes.
- Registry Manager: Maintains the Electricity Registry (a national database of every point of connection (ICP)) and manages customer switching protocols, compliance reporting and ICP data integrity.
- Wholesale Information and Trading System (WITS) Manager: Operates the 24/7 WITS platform for submitting bids/offers, publishing real-time prices and facilitating market transparency.
We will run a single-stage procurement process, which will include issuing a Request for Proposal (RFP).
Indicative timeframes (which may be subject to change) are:
- Early market engagement: April 2026
- Release of RFP documentation: 1 June 2026
- RFP closing date: 30 September 2026
- Shortlisting of suppliers: December 2026
- Select preferred supplier: March/April 2027
- Contract start date (for continuing services): 1 July 2027
- Contract start date (for services that change supplier): 1 October 2027
The Authority is also developing a 10-year roadmap for enhancing the MOSP arrangements. This roadmap will inform the upcoming procurement process and will guide how we manage and direct the new providers over time. We plan to publish a consultation paper on proposed changes in mid-2026.
