The Australian state of Victoria is a pioneer of 'smart' electricity metering for domestic customers. It's a big challenge for data storage, manipulation and presentation.
'Smart metering' is a well established technology for large electricity users, but there's a growing push to fit such meters for all customers. Smart meters offer enormous advantages for energy providers and retailers, and they empower consumers to make more informed decisions about their own energy usage.
In Australia, where the largest Orion users are based, smart metering is taking off in a big way. In 2009 the state of Victoria began rolling out smart meters, with the intention to have the entire state converted by the end of 2013.
From the retailer's point of view, the benefits are obvious. Smart meters allow for more precise and responsive tariffs, and for customer charges that reflect the actual costs of providing power in real time. Moreover, they remove the need for meter readers to manually visit every site every few months - a major ongoing cost saving - and greatly reduce the company's reliance on estimated reads for billing, which is always a cause of uncertainty and sometimes of customer dissatisfaction.
But this convenience comes at a cost. Instead of one meter read every two or three months, now we need to store one read for every half hour. That's a several-thousand-fold increase in the volume of data to be stored, which needs to be analysed and aggregated in order to produce accurate invoices.
Orion's Advanced Metering module separates the meter data from the main database. All meter reads are stored, but the AM database also aggregates data at various levels of granularity ready to serve to Orion when needed. So when the invoicing process wants to know, for instance, 'how many units did this customer use during the daytime on public holidays during January?', the AM database doesn't need to look up every half-hourly value and calculate the answer - the information is ready and waiting to be served up.
This allows Orion to generate invoices based on complete and accurate data, in no more time than it would take to calculate from monthly reads. Orion AM is a sophisticated service that positions our customers well to take every advantage of the smart metering revolution.
