Powering Up – Building a Data Warehouse
The opening of the New Zealand electricity industry to competition bought its own challenges to this large state-owned enterprise. To be able to participate in this sharing of the electricity market, this power utility had to build an ultra-reliable data warehouse that collected real-time power pricing data 24 by 7. Millions of dollars of trades are done daily so both system reliability and timely delivery of trading data are critical.
Sysware consultants were instrumental in developing and supporting these applications that helped drive the business. Working with an ETL (extract, transform and load) tool, our consultants built many ETL and monitoring programs to provide the energy traders with the appropriate data. The project included providing OLAP data structures for end users to exploit, the development of web-based reporting for end users; and the establishment and optimisation of the reporting architecture.
