Tender Overview

Powerlink Queensland is undertaking a Next Generation Network Operations (NGNO) Program in order to modernise its operational capability by creating an integrated set of contemporary technology systems, data management practices and processes that provide efficient operation of Powerlink’s high voltage transmission network.

The cornerstone of the NGNO program is the Advanced Energy Management System (AEMS) – which is replacing Powerlink’s end-of-life SCADA platform[1]. The AEMS is used to operate the network via real time control of equipment, and it contains a data model of the network that is used for prediction of power flows and market conditions, contingency analysis and automation of advanced network control schemes.

In order to construct this model and to maintain its currency as the physical transmission network changes, the AEMS needs to have its data model constantly updated from various sources. The Data Integration and Management Application (DIMA) platform performs this function, via a number of sub-functions which include:

  • integrating data from a number of sources, both as inputs and outputs;
  • validating it against business rules;
  • structuring it and formatting data to conform to the data model that is used to operate the network;
  • batching and scheduling data operations so that they can occur during planned windows to coincide with activities that are occurring in the transmission network (such as commissioning or decommissioning substations, lines or other power transmission plant); and
  • creating curated exports of data in specific formats.

As the current DIMA2 platform has evolved organically to meet these growing requirements as both the Transmission Network and the amount of data needed to manage the Transmission Network have grown, the current platform has a number of limitations and impediments that were not envisioned during its previous design.
As the DIMA2 platform needs to be significantly modified in order to support the integration with the new AEMS and its data model, Powerlink is taking this opportunity to redevelop DIMA to modernise it into a contemporary platform that is fit-for-purpose and is able to be expanded upon to meet future requirements. This redeveloped instance of the platform has been designated DIMA3.

The development of DIMA3 is subject to uncertainty and a number of constraints, including the following:

  • The NGNO program, and especially the AEMS project impose a number of dependencies on the DIMA3 project, including the timelines, budgets and overall resourcing of the program. The program is complex and is expected to be rebaselined occasionally over the program’s lifecycle, so projects and milestones will be subject to delays or need to accelerate in order to accommodate this.
  • The AEMS project is still in its design phase, and as such its integration requirements and its data model are in a state of flux. The DIMA3 platform will need to be able to be developed while managing this uncertainty, so a flexible, modular solution and delivery methodology are necessary to manage this uncertainty over the project’s lifecycle.

Powerlink is seeking to engage with organisations that have the capabilities (both skills and capacity) necessary to develop DIMA3 in a constrained, uncertain environment to:

  • continue to manage its requirements over the projects lifecycle – via defining, refining, verifying, validating or managing changes that occur as a result of:
    • dependencies in the program,
    • changes to the project scope; or
    • as a product of the vendor’s advice to Powerlink.
  • design an appropriate technology solution that suits Powerlink’s technical environment, and that provides the appropriate levels of scalability, security, extensibility and ease of support necessary for Powerlink to meet its future requirements.
  • manage the development process, with an appropriate methodology used to modularise the platform, deliver it in phases or tranches, or to otherwise containerise risk and structure the development to manage uncertainty and/or changes in requirements or scope.
  • develop an appropriate test strategy and toolsets to enable high quality assurance of the solution and its integrations.
  • develop an appropriate deployment methodology that includes any necessary data conversion, ensuring that appropriate rollback plans are available.
  • handover the platform to Powerlink’s operational teams, with appropriate documentation, training and knowledge transfer throughout the project to facilitate this.
  • any other capabilities the vendor believes is necessary to meet Powerlink’s requirements or constraints, or otherwise adds long-term benefit and capability, or removes risk from the implementation or ongoing management of the platform.
