Transitioning to a more digital electricity system

Enabling market evolution: Market Operation Service Provider 10-year roadmap

Upcoming Open Closed Decision

View submissions Submissions closed 28 July 2026

Decision

The Electricity Authority has decided to focus on modernising data sharing and governance arrangements ahead of considering any structural reform of market operation service provider (MOSP) services.

We will support modernisation of existing data interfaces following the start of the new MOSP contracts from July 2027 and integrate any necessary changes to the existing electricity information exchange protocols. This will include any changes arising from a consumer data right in the retail electricity sector.

Starting in Q4 2026 and working through to Q2 2027, we will develop a programme for assessing the need for further modernisation. This work will be progressed through engagement with stakeholders and our advisory groups, where appropriate.

We would like to thank all submitters who provided feedback on this consultation.

Market operation service provider 10-year roadmap next steps - Next steps

Consultation

This consultation sought feedback on our view of the issues facing our Market Operations Service Provider (MOSP) contractors and our proposed approach to modernising the services.

We contract five contestable MOSPs to operate the electricity markets efficiently and facilitate market development:

Clearing Manager – responsible for financial management and settlement of wholesale market transactions
Reconciliation Manager – ensures consumption volumes are allocated to the correct traders for settlement
Wholesale Information and Trading System (WITS) Manager - responsible for managing spot market data transfers and publication
Registry Manager – maintains the register of consumption ICPs and the registry hub for managing regulated consumption data requests from approved third parties
Financial Transmission Rights (FTR) Manager – operates the FTR market

The consultation paper sought feedback on the Authority’s assessment of:

the challenges facing our MOSPs and
potential changes to the services to meet these challenges.

The quantity of uses and users of market data – both wholesale market data and consumer data from individual ICPs – has been changing rapidly over recent years. We expect the rate of change to accelerate; meeting these growing needs for data will require significant changes to our existing MOSP systems.

Our current commercial arrangements make widespread change complex to manage and potentially more costly and time consuming than it could be. Co-ordinating changes across multiple systems and vendors introduces scheduling and financial risk to policy implementation projects.

We sought feedback on our proposal to rationalise and re-scope our MOSP services to be:

easier to manage commercially,
easier to coordinate change across and
able to meet the future challenges of consumer and market data management and sharing.

We received 13 submissions, as published below.
