Longreach Solar Farm

Client: Canadian Solar
Location: Queensland, Australia
Date: March 17

Supporting the development of valuable renewable power generation from the Australian sun

Background

The 17 MWp Longreach Solar Farm to the east of Longreach in Central Queensland was planned and developed by Canadian Solar and started construction in March 2017.  The project involves 51 300 ground-mounted solar PV panels on 52 hectares using single-axis tracking, creating enough renewable energy to power between 5000 and 7000 average homes.

RCR O’Donnell Griffin is undertaking the engineering, procurement and construction of the project. Entura was engaged by the project developer, Canadian Solar, to act as owner’s engineer for the project.

With utility-scale solar energy relatively new in Australia, Canadian Solar faced the challenge of ensuring the implementation of the project achieved high quality standards whilst adhering to budget and audit requirements.

Entura was ideally placed to provide this service and the necessary oversight, with comprehensive knowledge of local standards and requirements, as well as experience with solar technology, design and performance, and utility generator connections.

Solution

In the role of owner’s engineer, Entura was responsible for the concept and detailed design review including the array layout, civil works, AC and DC design, SCADA and structural elements. Entura also reviewed management plans, procurement specifications, environmental compliance and the proposed inspection test plans for construction.

During the construction phase, Entura is providing advisory and technical support, review of commissioning test results, and HV auditing and pre-commissioning.

Outcome

Design is finalised and construction has commenced. During the design process, Entura identified a range of design improvements and provided a critical role in ensuring integrity of the tracker piles. We provided rapid turnaround and guidance on a full range of issues faced by the client during the design process, avoiding unnecessary additional costs in the EPC contract and delays in connection and energisation.
