My understanding is that Smart Meters already installed may be a barrier to swiching supplier because they do not have a universal communication protocol. It is only the 2nd generation SMET2 meters (due from about now) that may be compatible with all suppliers. Early meters may have to be regarded as 'dumb' on a change of supplier and revert to manual meter reading. Apparently sometime in the next few years the first generation meters will be upgraded remotely to become compatible with other supplirs.
Mind you I don't see where the benefits arise since I haven't had a meter read for several years now (other then statutory reads) since I was submitting my own readings online. Moreover I don't see the slightest hope of reduced tariffs for smart meters - think of the costs of the national roll out ... 23 million homes, some 38-40 million meters at a unit cost of say £40 plus cost of labour at 1.5 hours per meter (+ overheads) added to which the service life of the new meters is less than the current meters with a forecast life of only 10 years.

I stand corrected in theory If you read further down under "How are the exports measured?" you will find the theory is being put into practice. Bob, the key words are "in future". There is nothing in place for the SM to monitor the export at present.

Except that it is impossible to get electricity from your house into the grid. That's why there's been no hurry to meter it and that's why the payments are "deemed to be 50%" of your panel's output. Any electricity actually going beyond your meter is lost in heat at the first substation it meets. All helps global warming.......

Nick As we generate at 243volts and the grid runs at 230volts we are feeding the grid. Also, as the quantum (amps) is relatively minor i would say it is highly likely that it is gainfully consumes before it reaches the nearest SS. So no contribution to global warming, me thinks!

Nick I'm afraid you are misusing the term "grid". It's true that solar-generated power isn't transformed back up to the high voltages used on the Transmission network, but it's not accurate to say it's not available on the grid. All the homes downstream of the substation will be able to make use of any local generation, and it all acts to reduce load (and therefore generation requirements) on the grid as a whole. Remember that although different parts of the National Grid operate at different voltages, it all operates at the same frequency. Extra load on the network causes the frequency to drop, excess generation causes it to rise. This effect will happen across the entire network simultaneously, regardless of the voltage or where the load or generation is occurring. There are many mechanisms that the National Grid Company uses to balance generation and demand on the system, and various levels of response time involved. For example, some industries have special contracts which mean they have special kit installed in their supplies to drop power with sub-second response to help balance the grid. All solar power generation is a useful resource, it reduces the need for fossil generation, and with the rapid growth of battery storage, it offers a real opportunity for small generators to participate in the market - which is potentially very lucrative. On September 14th last year at 12:00 (Noon), the spot price for electricity went from the base price of £100/MWh to over £1500/MWh. There's loads of companies putting together mechanisms to aggregate micro generators into tradeable blocks.

Given our rainfall especially today at home I am surprised no one has come up with micro turbines for down pipes, something we have in abundance over sunshine!
