Mount Majura Solar Farm - the National Capital Authority

Installation of electrical cabling, inverters and associated electrical equipmentPreparation and installation of grid connection infrastructure and associated upgrade to existing oradditional works to 11,000V distribution network onsite and/or nearby siteInstallation of site facilities, storage facilities, access tracks, fencing and landscapingCommissioning and testingRestoration and revegetation of disturbed onsite areas and removal of waste from site andappropriate disposal on completion of construction works.Construction works would be confined to standard construction hours (Monday-Friday 7am-6pm, Saturday8am-1pm). These working hours have been proposed to allow reasonable efficiencies of effort to achievemaximum productivity to minimise the overall construction duration. It is not expected that night work wouldbe required, however, some work may occur overnight due to logistical reasons.OPERATIONAL REQUIREMENTSThe Proposed Works would operate for a period of up to 50 years.Monitoring and control of the facility would be conducted from a remote monitoring centre, therefore therewould be no permanent onsite presence. A supervisory control and data acquisition (SCADA) system wouldmonitor the solar farm and identify any faults, which could then be addressed by isolating and shutting downthe relevant array block, pending diagnosis and repair by onsite technicians.To ensure the Proposed Works operate in a safe and reliable manner, it would require regular inspectionand maintenance on an ‘as needs’ basis. This would generally be carried out using standard light vehiclesand maintenance crews would attend the site as required. It is possible that some equipment may requireunscheduled repair or replacement.It is not expected that any material water usage would be required, as cleaning of the array would only occuron an events basis (i.e. after a dust storm) rather than on a regular scheduled basis. Washing would beundertaken using water only without detergent. Water would be sourced from commercial sources and mostlikely applied using a portable pressure washer or water truck.Security staff may attend the site on a sporadic or call out basis and other security provisions may includemotion activated security lighting, cameras, motion sensors, fencing and warning signs to preventunauthorised access.General site maintenance such as ground cover and weed control would also be required to responsiblymanage the facility in the context of its rural surrounds.
