EnergyLink has offered the EnergyLink smart energy management system with submetering to this golf club in Sydney. EnergyLink allows increased visibility into electricity consumption, automated daily, weekly and monthly reports, and an engineer to look after the site’s behaviour on a daily ongoing basis. The golf club has experienced sharp increases in energy, network and demand charges in the past and needs a system to improve air conditioning profiles, afterhours base loads and highlight potential electricity efficiencies on site.
EnergyLink is an energy management system unlike any other. EnergyLink is easily installed, allowing businesses to monitor and control electricity usage at a circuit and appliance level.

Preventative savings regarding demand have been identified at around $11,000 per annum, as a single spike in demand at the wrong time results in a larger charge for the following 12 months. While the pumps were largely kept to off peak times; at one period of time they were moved to operate during the window of peak demand (2-8 pm). It was recommended that the pumps be locked out of operation for this period of time.
Through an LED upgrade being done on site, the lighting operations on site have been made more efficient by replacing dated halogen bulbs, CFLs, T8 fluoro tubes. Savings so far are tracking at approximately 4,200 kWh per month, or $10,000 over the course of a year at a rate of $0.20/kWh.
Through metering it was found that a number of water pumps related to irrigation were running 24/7 at a load of 7 kW. The site superintendent confirmed that these only needed to run throughout summer continuously, and so were switched off during the winter and the shoulder seasons to achieve the combined savings of 40,000 kWh, or $8,000 at a rate of $0.20/kWh.
On DB 1, electricity spikes were found to be occurring on a daily basis during the afternoon peak pricing period. A large number of battery chargers listed on this DB highlighted the opportunity to move 35 kVA and 20 MWh worth of electricity to an off peak period. Providing this combination of demand and consumption reduction from a peak period enables savings of up to $5,500 per annum.
Total Savings: $31,000
– $10,000 savings from LED upgrade
– $8,000 savings from demand management
– $7,500 savings from operational efficiency
– $5,500 savings by shifting battery charging to off-peak
