Service Maintenance

JDP #45 – Maintain Service, Building & Equipment and ACAM Programme (SO)

Description

Transpower Service, Building & Equipment and ACAM programme.

Why we're doing the project

This programme will replace or upgrade hardware and software components that are approaching end of life or will be unsupported to avoid end of life failure risks, which would affect market system availability. In addition, the lifecycle programme includes changes required to adapt existing components due to changes in underlying infrastructure within the Transpower environment.

Estimated impact to Market Participants

No direct market participant impact.

JDP # 62 –Increase Capacity for Special Protection Scheme – Tighter Grid Management (SO)

Description

Focus on improving market systems security to ensure it aligns with industry and government requirements.

Why we're doing the project

This programme of work will reduce the risk of cyber security attacks and/ or breaches, which is critical in the current climate of increasing global cyber security threats.

Estimated impact to Market Participants

No direct market participant impact.

JDP #63 – NCC Voltage Management and Dispatch -  Tighter Grid Management (SO)

Description

Energy and reserves dispatch is governed by the market rules of dispatch. This same level of governance does not apply to voltage dispatch.

Why we're doing the project

Additional automation (closer to 80 %) of dispatch and voltage management to enable efficiency gains and improve the consistency of voltage management. 

Estimated impact to Market Participants

Improved quality of dispatch by introducing a consistent approach.

JDP #59 – SCADA Upgrade #1(SO)

Description

Upgrade the SCADA/EMS system with supporting hardware and software infrastructure to ensure ongoing vendor support..

Why we're doing the project

The SCADA/EMS system is the primary tool for operating the transmission network. It also provides critical feeds to the Market System and live data to distribution companies. Although the SCADA/EMS system operates largely in an isolated environment, its susceptibility to cyber security vulnerabilities will grow as the vendor no longer provides security patches. It is therefore prudent to upgrade critical systems to current, vendor-supported versions better designed to manage those threats.

Estimated impact to Market Participants

No direct market participant impact.

JDP #32 - Situational Intelligence Programme (SO)

Description

Maintain benefit of the Situational Awareness Tool (SAT) with Enhanced Information Display (EID) tool .

Why we're doing the project

To provide increased visibility, every five minutes, of the current flow/constraint status of the grid. 

Estimated impact to Market Participants

No direct market participant impact.

JDP #52 - Scenario Analysis(SO)

Description

Reduce operational risk by enabling the ability to study and understand future power system scenarios

Why we're doing the project

To provide coordinators with visibility of future power system scenarios, increasing coordinators’ knowledge of system event impacts, and their understanding of these impacts on generation dispatch. This will enable coordinators to prepare suitable mitigations prior to an event occurring, and generators and price sensitive loads to efficiently plan their scheduling.

Estimated impact to Market Participants

No direct market participant impact.

Service Enhancement

JDP #51 – Dispatch Service Enhancements (SO)

Description

Implement alternate communication protocols and network routes for dispatch instructions to be issued to participants and to provide a higher level of redundancy.

Why we're doing the project

The project will work with industry participants to introduce alternate communications protocols to manage dispatch. This will reduce the barrier to entry for potential (new) generators by enabling the use of more open communication standards. The project will also facilitate the introduction of dual network routes to enable continued dispatch, to generators who are currently on a single network route.

Estimated impact to Market Participants

Reduced technical barriers to market entry and participation by enabling market participants to procure or develop their own software to process market dispatch instructions and transition off the legacy dispatch system.

JDP # 61 –Wind Forecasting (SO)

Description

Implementing a pilot wind generation forecasting service, which assesses its benefits to the management of the NZ power system.

Why we're doing the project

The most significant benefits would be obtained if the forecast tool was integrated in control room tools and procedures -  in particular production schedules and contingency analysis.

Estimated impact to Market Participants

Replace the current obligations of wind farms to forecast their generation with a central wind forecasting tool.
