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

We are seeking feedback on our view of the issues facing our Market Operations Service Provider (MOSP) contractors and proposed approaches to modernise and evolve the services.

The consultation paper Enabling Market Evolution: a 10-year Market Operations Service Provider Roadmap proposes to rationalise and re-scope our MOSP services over time so they are easier to manage commercially, easier to coordinate change across, and more able to meet the future challenges of consumer and market data management and sharing.

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

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

Demand for data is growing

The MOSP roles require that large amounts of data are transferred between themselves and market participants daily. These high-volume data transfers are usually scheduled and predictable. This has allowed legacy systems, such as CSV file transfers, to remain in service as they adequately support the data load. The relatively small number of interfaces and uses for the data has historically limited the need for significant upgrades.

As the electricity market has matured and technology has improved, the need for wider and more timely access to market data has increased. This includes consumer data.

Changes, such as the increased use of domestic solar and battery systems and the need for greater operational visibility of resources, will likely increase the volume and complexity of data stored and transferred between the MOSPs and participants.

We’re seeking feedback on our assessment of the challenges facing MOSPs and potential changes to the services to meet these challenges.

Submissions close at 5pm, Tuesday 14 July 2026.

MOSP procurement process

Separately, we have started a competitive procurement process for five MOSP services. New contracts are expected to begin on 1 July 2027, but may start later to allow for transition where new supplier(s) are chosen. Details of the tender process can be found on the Government Electronic Tender Service (GETS).
