A greenfields operation, the company originally tried to get a handle on its data by feeding information into spreadsheets and manually slicing and dicing.
But as Ms Carmody noted; 'It was very hard to assure the data integrity.' Not only was information about the different turbines collected from multiple sources, showing how they were performing and when they were scheduled for maintenance and so forth, all the company's income was in different currencies and had to be manipulated before being input to the spreadsheets.
And although there was industrial control data generated in the turbines' SCADA (supervisory control and data acquisition) systems, it could not easily be manually loaded into the spreadsheets.
Given the high revenue stakes it was important that a more comprehensive, accurate and real time information source was developed. Working with services provider Oakton, Infigen has now implemented Microsoft SQL 2008 as the underlying platform for its business intelligence.
Working with the business Ms Carmody and Oakton developed a set of requirements, definitions and calculations of the loss factors associated with how efficiently power from the turbines was getting to the grid. This informed the underpinning calculations that needed to be performed on the raw data associated with each turbine.
The company also had to negotiate with the wind turbine manufacturers to get access to their SCADA data. Ms Carmody acknowledged that many were reluctant to provide that access initially, although SCADA data is now being fed via satellite links or 3G connections into Infigen's application.
'Because of maintenance they might not be available when there is a high wind,' she explained. But thanks to meteorological records and analysis the company claims it can predict with some degree of accuracy when there will be high winds, and when its turbines can produce electricity.
'Also in summer we know it is a high power period after 3pm when people get home from school and work - you don't want your turbines not generating then,' she said.
Although Ms Carmody acknowledged that Infigen needed to do more measurement about the economic benefit of the business intelligence system, which cost a tad under $1 million, she said it had already covered its costs in terms of improved access to intelligence to manage the wind farms.
The system can be used to provide regular and ad hoc reports for Infigen management, and each morning when executives check their computers they can see a chart showing the actual generation from a turbine or wind farm compared to its budget.
