CITY OF SYDNEY COUNCIL IS COMMITTED THEIR SUSTAINABILITY PLAN FOR THE CITY
The City of Sydney is installing low-carbon cogeneration in the Ian Thorpe Aquatic Centre to produce clean, locally produced energy for the indoor heated pool, café and fitness centre.
This cogeneration unit is part of the City’s trigeneration program, and will provide power and heating at the centre, reducing
greenhouse gas emissions by more than 500 tonnes a year.
Many NSW councils already use cogeneration/trigeneration at their pools, including Willoughby, Wagga Wagga, North Sydney and Hornsby. It is also installed at the aquatic centre at Sydney Olympic Park.
Lord Mayor Clover Moore said the City had made a long-term commitment to cut carbon pollution and locally produced energy would make a significant contribution to its emissions reduction target of 70 per cent by 2030.
“With cities responsible for more than 70 per cent of carbon emissions, it’s cities that have the greatest opportunity for action,” she said.
“We’ve already cut emissions in our own operations by 27 per cent. Under our new environmental action plan we’re committing to reducing emissions by 44 per cent by 2021 and cogeneration at Ian Thorpe aquatic centre will play a significant role in reaching that target.”
The cost of carbon abatement per tonne using trigeneration at Ian Thorpe Aquatic Centre is lower than Greenpower, and the system also provides infrastructure that improves the building’s overall energy efficiency.
Moore said locally-produced electricity reduces carbon pollution, improves energy efficiency and reduces high network charges from using the inefficient poles and wires that bring electricity from the Hunter Valley and beyond.
Cogeneration and trigeneration plants use natural or renewable gases to produce electricity. The heat by-product from the process that is wasted at centralised power stations can be captured and used for air conditioning, space heating and hot water services – making the facilities more than twice as efficient as coal-fired power plants.
“A trigeneration plant has recently been installed on the roof of Sydney Town Hall House to power the town hall and its office buildings and is currently in the testing phase,” she said. “Together with the solar panels that have already been installed, this will provide energy for hundreds of lights, printers and computers as well as air conditioning and space heating and charging for the City’s electric vehicle fleet.”
The City has already retrofitted 45 of its properties to reduce electricity and water use, generating operational savings of more than $1 million a year.
The Better Buildings Partnership includes the owners of more than half the commercial office space in the city centre and was established by the City of Sydney. By improving the energy efficiency of their buildings, the partnership has avoided more than 145,000 tonnes of carbon emissions in the last year as well as reduced costs by more than $30 million.

HOW TO REDUCE PEAK DEMAND CHARGES ON YOUR ELECTRICITY BILL
The past few years has seen a major shift in the way electricity retailers charge for your electricity usage. This shift results in exorbitant peak demand charges, while lowering consumption rates on a kilowatt-hours (kWh) basis. Peak demand charges now make up a large proportion of your total bill.
While most consumers are confused by an ill-explained formula, this shift presents various opportunities in implementing methods to reduce your peak energy demand charges. This paper demystifies electricity charges, along with addressing such methods in reducing demand charges.
Previously, both domestic and commercial customers paid only for the electricity they used in cents per kWh. Their bill was a simple summation of the amount of power they used in kWh over a given period.
Electricity retailers now have a new way of billing their customers to pass on the cost of energy demand spikes at peak energy periods. Bills are now broken up into 3 categories
- Energy usage (charged in cents/kWh),
- Poles and wires charges, passed on from the network (charged in cents/kWh),
- Peak Demand charges (typically charged in $/KVA/month).
By billing in this way, retailers charge consumers for their potential maximum peak demand, often over a twelve month period. Their reasoning for Peak Demand charges, is to allow for the “setting aside” of sufficient electricity during peak events should it be required. This is typically based on the hottest days of the year where a large amount of electricity is being used by air conditioning systems running at maximum capacity.
The peak demand charge has been creeping up over time and now for most commercial and industrial consumers, these network demand charges make up the bulk of an electricity bill.
Typical electricity consumers are now left scratching their heads in an effort to reduce the peak demand charges and “flatten out” their electricity demand.
Jake Thodey, principal engineer from Simons Green Energy (SGE) has offered the following suggestions for ways in which you can look at flattening out your electricity demand peaks.
- Smart load management. This method suggests you run non-essential or periodically essential services outside of the peak demand times in order to passively reduce total electrical demand. It can be as simple as turning air conditioning temperatures set points up a few degrees in the middle of the day on very hot days to try to reduce the strain on the cooling system, and thus the reduce the total electrical draw.
- Load shedding. This method is similar to the above however it is more actively controlled approach. This method employs an array of electronically controlled and metered sub-systems, which actively turn off or ramp down non-essential high consumption circuits in order to reduce the total demand. For example some new “smart fridges” can sense when the grid is strained and do not turn on their compressors at peak times.
- Non-conventional chillers. Reducing the need for electricity during high-load periods is key, and as electricity consumption is typically related to temperature, natural gas powered chillers such as natural gas heat pumps and natural gas-fired absorption chillers can offer a cost saving and a peak demand shaving alternative to standard electrical chillers.
- Energy storage and demand levelling. Moving consumption from peak to off-peak periods has the dual benefit of reducing peak demand as well as shifting usage costs to lower off-peak rates. As an example, chilled water or phase change thermal storage systems may be used to generate the cooling required during off-peak periods, for use in the middle of the day when rates are high.
- Extra generation. This system employs paralleling embedded generators such as natural gas cogeneration systems, gas generators or parallel-enabled diesel generators. The system uses an alternative energy source, such as natural gas to generate the power instead of buying the power from the grid. This fuel switching has the benefit of avoiding the peak demand charge as there is no peak demand charge for natural gas, and the power generated onsite is very often at a cheaper price (c/kWh) than buying the electricity from the grid.
By employing a range of the above measures, businesses can reduce the strain on the grid as well as on their bottom line. By diversifying energy dependence with non-standard solutions, businesses can invest in their future profits wisely with new ways of managing energy.

HOW TRIGENERATION WORKS
Trigeneration, or combined heat, power and cooling (CHPC), is a cost-cutting and emissions-reducing method for generating power at a business site. Essentially, it recycles waste energy to produce heat and cooling as a free by-product. Our trigeneration systems comprise a cogeneration unit and non-polluting absorption chiller. Minimal energy is lost in transmission, achieving energy efficiency as high as 85 per cent.
