I would like to build some tables & from them graphs of the costs of energy from different suppliers across a range of consumptions. Suppliers now, mostly, charge a standing charge which can vary greatly and with them a range of costs per kilowatt. Put simply, the charges are gener ally linear, of the shape a + bx , where a is the standing charge, b is th e unit charge & x is the amount used.
With a good overview of a supplier's tariffs a simple graph could be drawn for each plan and the cross-over points identified.
Does anyone know where the data can be found? All, well it appears to be a ll, the comparison sites require you to load your specific usage and then t hey send back spot prices derived from each supplier's data. Effectively, as single point on a graph.
Access to an overview of all the tariffs in an area would enable a much mor e informed judgement to be made and would identify if you were near a cross
-over point.
