Project Overview:
The Gruyere Power Station Extension at the Gruyere Gold Mine, located in the Yamarna Greenstone Belt, aimed to increase the facility’s capacity to 39 MW. This brownfield project added a gas-fired Jenbacher 624 engine/generator skid and integrated a Battery Energy Storage System (BESS) to support operations. Altrad (formerly Valmec) provided comprehensive installation and integration services, leveraging its expertise in working within constrained footprints and interfacing with third-party contractors.
Scope:
- Installation of a gas-fired Jenbacher 624 engine/generator skid.
- Ancillary equipment to support one engine and tie it into existing piping and electrical systems.
- Provision for future gas generator equipment within the engine hall expansion.
- High-voltage (HV) cable terminations and VLF testing.
- Installation of two BESS units (2 MW / 2.5 MWh capacity).
- Integration of a fibre optic network for enhanced operational connectivity.
Outcomes:
- Increased the Gruyere Power Station’s capacity to meet operational demands.
- Successfully executed work within a limited footprint, ensuring seamless coordination with third-party contractors.
- Delivered high-quality construction, including HV cable terminations and BESS integration, supporting long-term operational reliability.
- Utilised local suppliers for concrete, coatings, and off-site manufacturing, contributing to regional economic growth.
- Reinforced Altrad’s ability to manage complex brownfield projects in remote locations with operational efficiency and flexibility.
