way to save millions from household electricity bills  A
glenrothes housing estate is being hailed as the site of a
breakthrough in the quest for a "smart grid" that will reduce
network losses of electricity, saving millions of pounds for
consumers.  Network waste is estimated by the Department of
Energy and Climate Change (DECC) at £3 billion a year in the UK,
mainly through "copper losses" (heat in the cable), and theft.
As the cost is borne by consumers rather than suppliers, power
companies have so far lacked incentives to tackle the issue.
The Glenrothes pilot project, part of Fife Council's Light Fife
Green initiative to cut spending and carbon emissions on street
lighting, has been a test bed for power line carrier (PLC)
technology which transmits data along electricity lines.  The
pilot uses two-way communications between pillars and
substations to measure the energy saved by d
