Data Centre Consultants

Data centres are the backbone of digital infrastructure, making online services like cloud storage and communication networks possible. They are specialised facilities that house and manage large amounts of computer servers, networking equipment, and data storage systems.

The bulk of the power used by the servers generates heat, which needs to be removed from the facility. Data centres require high levels of reliability (multiple network connections and multiple on-site generators).

Some data centre developers also require 100% renewable energy generated at the time of consumption. This presents an interesting challenge requiring renewable generation, energy storage and renewable back up fuels.

How our data centre consultants help

Arche Energy advises data centre developers and landowners on the question that decides the project: can this site actually get the power it needs? Our data centre consultants work with you to understand what your site needs to get powered and stay powered.

We help you assess the technical and commercial factors that influence data centre development, including:

site power feasibility assessments,
grid connection and capacity,
On-site generation,
battery energy storage systems (BESS),
redundancy and resilience planning,
energy procurement, including Power Purchase Agreements (PPAs).

Our clients include hyperscale and colocation developers planning new facilities, landowners marketing powered sites, and network businesses assessing connection requests. We provide guidance on project risks and practical pathways to energisation.

Arche works on the owner side and remains independent of equipment suppliers. This means our advice is based on your project’s requirements — not the sale of a particular technology or infrastructure. Our practical, commercial approach gives you a clear view of your options, project risks, and the steps needed to move forward.

Data centre engineering

Data centre engineering at Arche covers everything between the network connection point and the data hall switchboard. We assess connection requirements, identify technical constraints, and develop practical solutions for reliable and scalable power infrastructure.

Our work includes high voltage network connections, substation and transformer planning, three-phase power distribution, backup generation, and battery energy storage system (BESS) integration.

Three-phase power for data centres

Three-phase power is widely used in large commercial and industrial facilities, including data centres, where it supports high electrical loads across servers, cooling systems, and other critical infrastructure. The design of the three-phase power system also needs to account for reliability, load requirements, redundancy, and future expansion.

Arche supports data centre projects through network connection studies, feasibility assessments, connection applications, and electrical infrastructure planning. We work through applicable network connection processes and project requirements to develop reliable and commercially practical power solutions.

What makes a site data centre ready

A powered site is not the same as a data centre ready site. The availability of electricity, the connection timeframe and supporting infrastructure often determine if a project can proceed. The most important factors are power, land, planning and access to supporting utilities.

Available network capacity is often the first constraint. A site may be located near electrical infrastructure, but available capacity at the grid connection point can be limited or already allocated to other projects.
The timeframe to energisation can determine project viability. Connection assessments, network upgrades and approval processes can extend timelines well beyond initial development expectations.
Land availability is only part of the requirement. Sites also need compliant easements, access corridors, and space for substations, transmission infrastructure, and supporting services.
Water and cooling requirements must be considered early. Data centres generate significant heat and require reliable water cooling solutions that align with site conditions and available infrastructure.
Planning and approvals can be as important as power availability. A site that is technically suitable may still face development constraints, approval requirements, and other planning challenges.

Why data centre projects stall

Most Australian data centre projects are not delayed by construction, they are delayed by the connection process.

Access to power is often the first hurdle. A site may look suitable, but limited network capacity and connection queues can delay energisation and affect project timelines. New data centre developments also compete for infrastructure in areas where electricity demand is growing.
Equipment procurement can add further delays. Long lead times for transformers, switchgear, and other critical electrical equipment can push out project schedules, particularly when network upgrades are required.
The availability of firmed power is another factor slowing down a data centre project. Developers need to plan for reliable power supply during periods of high demand or lower renewable generation.
Planning approvals can also add complexity, even after technical requirements have been addressed. Identifying these constraints early can reduce project risk and support more realistic planning.

Batteries and firmed power for data centres

As data centre power demand grows, battery energy storage systems (BESS) are becoming an important part of power supply and grid connection strategies. BESS for data centres can provide backup power, manage peak demand, and support connections where network capacity is constrained. These benefits can improve power reliability and, in some cases, reduce the need for immediate network upgrades.

BESS can also support firmed power by storing renewable energy and providing electricity when renewable generation is lower. Arche supports battery projects through Owner’s Engineering, project management, and network connection services.

FAQs

1. What does a data centre consultant do?

A data centre consultant provides independent, owner-side advice on site selection, power supply, and project development. We assess site suitability, network connection options, energy requirements, infrastructure constraints, and the pathway to energisation so developers and landowners can make informed decisions before major investment.

2. What makes a site data centre ready?

A site is data centre ready when it has sufficient connection capacity, a realistic pathway to energisation, suitable land, access to water and cooling infrastructure, and the necessary planning approvals. Having a power source nearby does not necessarily mean a site can support a data centre development.

3. How much power does a data centre need?

Data centre power requirements vary significantly depending on the size and type of facility. Small facilities (90m2) may require 10 to 50kW, while hyperscale developments (4,600m2) can demand 10 to >100MW. The final requirement depends on factors such as server capacity, cooling systems, redundancy, and future expansion plans.

4. Why do data centre projects get delayed in Australia?

Data centre projects are much more often delayed by power infrastructure rather than construction. Common challenges include network connection queues, long lead times for transformers and switchgear, and planning or approval requirements. Identifying these constraints early can reduce project risk and support more realistic delivery timelines.

5. Can a battery help a data centre get connected sooner?

A BESS can support connection outcomes in some situations. Batteries can manage demand, improve resilience, and reduce pressure on network infrastructure, which may help defer upgrades and create a more practical pathway to connection.
