Service Maintenance

JDP #33 – EMS Upgrade SO SCADA/PRISM Upgrade

Description

Maintain the present the level of system operator service

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. The current SCADA version is eight years old, and support for the operating system SCADA is running ends in July 2015. 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 #45 – Lifecycle Programme

Description

Upgrade the SCADA/EMS system from version 2.3 to 2.6 together with the supporting hardware and software infrastructure to ensure ongoing vendor support.

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 #46 – Security Programme

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 #47 – IT Reliability and Resiliency

Description

This programme of work is focused on  incrementally addressing technical complexity aimed at simplifying the market system.

Why we're doing the project

This programme of work is to ensure that the market system is fit-for-purpose for the planning period and risks to the Market System resiliency and reliability are addressed. Additionally, the simplification programme will minimise the need for replacement of the market system in future.

Estimated impact to Market Participants

No direct market participant impact.

JDP #48 – Delivery Improvement Programme

Description

Improve support systems to reduce anticipated future cost increases associated with making changes.

Why we're doing the project

The delivery improvement programme of work will help mitigate future costs increases associated with change. Investment in cost efficiencies such as manual process automation to prevent significant project cost increases as professional services fees rise.

Estimated impact to Market Participants

No direct market participant impact.

JDP #49 – Incremental Business Change Programme

Description

Maintain various market system components and associated support tools.

Why we're doing the project

This programme will replace or upgrade various market system support tools and associated components that are approaching end of life, will be unsupported to avoid end of life failure risks or are needed to be changed to maintain the system operators agreed service level.

Estimated impact to Market Participants

No direct market participant impact.

JDP #34 - Testing Training Simulator Environment (TTSE)

Description

Deliver improvements to the test and training simulator environment (TTSE) to enable realistic representation of the power system and a greater number of scenarios to be used for training purposes.

Why we're doing the project

The TTSE is used to train System Operations system coordinators, and Grid Asset Controllers. To be of value the training simulator must reflect reality. At present there are a number of implemented initiatives the simulator is unable to incorporate including the HVDC control system and the Christchurch reactive power control (RPC). The inability to incorporate these initiatives impacts simulator realism for users, and increases the processing and workarounds required to manually simulate these conditions.

Estimated impact to Market Participants

No direct market participant impact.

JDP #31 - TSAT Online

Description

Enable the real time use of the Transient Security Assessment Tool (TSAT), improving the ability to manage over and under frequency events.

Why we're doing the project

Based on the benefits provided by TSAT in near real time, there is an opportunity to use TSAT in real time to enable improved management of frequency events.

Estimated impact to Market Participants

No direct market participant impact.

JDP #59 – SCADA Upgrade #1

Description

Upgrade the SCADA/EMS system to the current version together with the 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 - Enhanced Information Display

Description

Migrate the Situational Awareness Tool (SAT), which was originally built as a proof of concept, to a supported platform with no functional changes.

Why we're doing the project

To ensure operational tools are on supported environments.

Estimated impact to Market Participants

No direct market participant impact.

JDP #52 - Scenario Analysis

Description

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

Why we're doing the project

To provide system 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 – EDF Improvements – Phase III

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 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, when a Transpower data-centre is unavailable.

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.

JDP #54 – Sensitivity Analysis

Description

Systems enhancing visibility of input data sensitivity through provision of schedule sensitivity information.

Why we're doing the project

Market participants have indicated that probabilistic load and price indication in the form of sensitivity schedules would provide significant benefit for effective decision making. They would be able to see the extent to which prices are likely to fluctuate in a trading period. This need is becoming more important as the Authority takes steps towards real time pricing.

Current-state capability to execute sensitivity analysis is hampered by inadequate tools and manual manipulation of input data. There is also no business process capability to do sensitivity analysis

We are investigating how we would add the necessary functionality to Market System tools, and existing dispatch and market analysis business processes. The ability to run automatic and manual schedules comprising sensitivity analysis will provide industry stakeholders and system operator staff with the knowledge and probability of system outcomes ahead of time.

Estimated impact to Market Participants

The objective is to provide market benefit through sensitivity schedule information being published automatically and regularly to industry, increasing information quality for more optimal operational and market decision making.

In addition we would hope to provide market benefit by increasing awareness of how operational decisions regarding security impact the industry.
