Collgar Wind Farm is a wind farm located approximately 25 kilometres south-east of Merredin, Western Australia. With 111 Vestas V90-2MW wind turbines (de-rated to 1.856MW) built in the first stage, and a total production capacity of 206 MW registered with AEMO, it is Western Australia's second largest wind farm. It is expected to generate 720 GWh on average per year over the 30-year life of the project. The farm's website notes it should produce 630 to 750 GWh of energy each year.It became fully operational in October 2011.
Feasibility studies were carried out between 2006 and 2008, and planning approval was granted in September 2008. In March 2010 Collgar Wind Farm Pty Ltd was sold to UBS International Infrastructure Fund and Retail Employees Superannuation Trust. Construction began in June 2010, the wind farm was connected to the grid in April 2011, and the first 50 turbines started operation in May 2011. The wind farm became fully operational in October 2011.
AEMO records begin in June 2011 for the wind farm. The generation table uses AEMO Facility SCADA to obtain generation values for each month. Collgar's code is INVESTEC_COLLGAR_WF1, so that is used as part of a SUMIF operation (shown below) on the table to get the total. Note that each month's values start 8 hours into the respective month and extend 8 hours into the next month.
