AGL Metering Data Errors

I am a retired electrical engineer and an early adopter of the AGL VPP. I maintain a database of daily consumption and solar production, sourcing data from the AGL website, SA Power Networks (SAPN) website, AGL Solar Command, Tesla and Fronius.The AGL csv data from their website is used to drive the AGL phone app and is the basis from which AGL bills are created. The 11th column in this data is a “Quality Flag” and is normally “A” for actual read from my smart meter.From 1st June 2017 until 13th ...

Re: An Engineer's Case Study: Panels Are A Must, But Forget The Battery

Hi Graham, I also have a spreadsheet of 30+ SA electricity plans and 19 SA gas plans.If you live in SA and would like me to tell you accurately and definitively which are the best plans for you, I can do so if you send me your bills.One year's worth will give a very good result, although it can be done from one bill, but two years would be slightly better as it would average over repeated seasons. My email address is rich.m.ball@gmail.com for easier communication. Cheers, Richard
