The proposed Bango Wind Farm could consist of up to 75 turbines depending on turbine selection. Current wind turbine technologies vary in geometry. As such, our approach to assessing impacts of the proposal will be based on greatest number and largest turbine (i.e. a conservative impact) to ensure we retain the flexibility to choose the most suitable wind turbine technology available in the market at the time of construction, post approval.
Currently towers ranging from 80 to 130 metres (m) and individual blade lengths from 40 to near 80 m are available in the market. These machines provide for a range of generation capacities from 1.5 to 3.5 mega watts (MW).
As with all wind farms, this project will also consist of other permanent ancillary structures and equipment which will be positioned in accordance with site constraints. These typically include:
- Access tracks and hardstand areas suitable for cranes;
- Overhead and underground electrical cabling;
- Substations (a main collector substation on site, and if necessary, a switching substation near to the point of connection);
- Wind measuring masts;
- Storage compounds; and,
- Operations buildings.
During the construction phase of a wind farm additional temporary facilities are likely to be required on site, for example mobile concrete batch plants, rock crushing compounds, and temporary site office buildings and facilities.
Bango Wind Farm May 2017 Update
|Number of turbines
|Wind farm size
|Average Households supplied
|Carbon dioxide saved
The capacity factor used in these calculations is 35.00%.
All the calculations used to estimate annual wind farm output, the number of households it will supply and the CO2 emissions saved, are generic figures based upon the calculations below.
1. Average Output
Wind Farm Capacity in MW x Capacity Factor (%) x Annual Hours (8760) = Wind Farm Output (gross yield in MWhr per year)
2. Households Supplied
Predicted Output / Average Australian Electricity Consumption per Household p.a. (6.926 MWhr*) = Number of Households
3. CO2 Emissions Avoided
Wind Farm Output x CO2 Savings per kWhr = CO2 Emissions Avoided
Our minimum and maximum emissions figures, in kilograms of CO2 emitted per MWhr, were obtained from the Australian Government Department of Climate Change (Jan 2008) National Greenhouse Accounts (NGA) Factors. A link to the site from which this came is also provided below:
