Some smart meters not so smart

by Russel Norman

An interesting article in issue 43 of Energy Watch, the Journal of the Sustainable Energy Forum, about the smart meters being made by Arc Innovation, which is wholly owned by Meridian Energy. (Issue 43 not on line yet) Arc is planning to install 110,000 of these meters in Christchurch over the next couple of years.

Smart meters could be a really useful way of telling consumers how much electricity they are using at any particular point and what the spot price of that electricity is. Knowing how much electricity you’re using and how much it is costing should have the effect of reducing use at peak points (when prices are higher) and hopefully reducing overall use by making people more aware of their consumption. More sophisticated versions in the future could even be programmed to turn applicances off or on depending on the spot price.

New Zealand retail electricity consumers are not currently exposed to the spot price but at the very least knowing how much we are using at any time would be a start. In the future consumers could be given the option of being exposed to the spot price rather than a fixed price.

Unfortunately it seems that the meters being manufactured will be “non-half-hourly compliant” which apparently means that they will record the power use each half hour and then transmit this info back to the electricity retailer/generators. Which won’t be much use to consumers and won’t acheive the goals of reducing use and peak load.

If this info is correct then we need to intervene quickly to make sure that an industry standard is set as to how intelligent these smart meters are. Otherwise we could be stuck with meters that don’t do that much.
