Transmission and Renewable Energy Zones

There is no transition without transmission.

Connecting renewable energy sources with load centres is a current challenge that the energy industry faces.

The role of the transmission system to to transport bulk power from its place of generation to major load centres such as cities and major industrial centres.

The purpose of a Renewable Energy Zone (REZ) is to provide the pioneering network infrastructure required to connect many, large, new renewable projects that are located within a region of high renewable energy resource.

Network Service Providers (NSPs), Governments and Industry face the challenge of extending and reinforcing our transmission networks to facilitate the large scale adoption of renewable energy. Arche Energy is contributing to the development of the Central West Orana (CWO) and New England (NE) REZs.

Transmission networks are essential for ensuring the efficient and reliable delivery of electricity from power generation sources to distribution networks and end-users. Arche’s focus is facilitating renewable energy zones, transmission line development, network connections for renewable and conventional energy generation, mines, and major energy consumers.

We also help our clients manage the contestable elements of the connection, including:

  • IUSA: Identified User Shared Assets
  • DCA: Dedicated Connection Assets
  • DNA: Designated Network Assets.

Our thorough review process encompasses resource quality, grid connection risks, approvals risks, construction risks, and operation risks along with technical review of project design.

We balance risk with practical solutions and mitigation advice.
