Net Work
Alan Winstanley
This month I report on forthcoming ‘energy smart appliances’ and a reader highlights looming
problems with Economy 7 electricity meters. I also reflect on nearly 30 years of using the
Internet and the end of my regular columns (but maybe not the end entirely).
S
mart meters have been a hot
Net Work topic for several years;
the energy sector continues its
drive to install them in every British
home. There’s no doubt that many consumers appreciate having a smart meter’s
in-home display (IHD) to track energy
consumption, but BBC News reported
that about four million of them currently
don’t work properly.
Much has been written about smart
meters going ‘dumb’, having connectivity problems or sending inaccurate
user data, resulting in overcharging.
Some householders are even being
paid to accept one: EDF (Électricité
de France) recently offered the author
a £150 bounty to sign up for a smart
meter, claiming that my current digital
electricity meter has reached the end
of its life. This novel twist may finally
tempt customers into accepting the
latest SMETS2 (Smart Metering Equipment Technical Specifications) meter.
I wrote half a decade ago (Net Work,
January 2020) about how the concept
of a Smart Meter Home Area Network
(SMHAN) would forever alter how
householders used appliances such as
dishwashers, tumble dryers or electric
vehicle chargers.
Industry and the government are now
talking about a new generation of ‘energy smart appliances’ (ESAs) as a way
of managing Demand Side Response
(DSR) – defined as “a means of changing electricity consumption in a way
that benefits the electricity system”.
ESAs have yet to materialise, but a
voluntary EU Code of Conduct for ‘interoperability and energy smart appliances’ was adopted Germany last year,
and the technical standards are now
being hammered out.
Once connected to a household’s
SMHAN, energy smart domestic appliances would ‘know’ what the cheapest tariffs are at any time of day, and
optimise the consumer’s energy usage
and billing accordingly. This may well
appeal to EV owners especially.
Appliances are getting ‘smarter’
To see which way we’re heading,
the British Standards Institute offers
4
heavy reading in a publicly available
specification (PAS) in PDF format at
https://pemag.au/link/ac4h
I was gratified to read that the proposals specify a “…standardised control, subject to an explicit consumer
consent, of energy smart appliances
(ESAs) on an electricity network.” So
consumers would have to opt in to
take advantage. Like smart meters,
ESAs will probably be touted as offering a consumer benefit, but the truth
is that they’re all about rationing our
faltering electricity supply.
According to Electrolux, nine manufacturers in addition to Electrolux
Group – including Miele, Turkey’s Arçelik, Mitsubishi Electric, Panasonic
and Vaillant Group – have committed
to the EU Code of Conduct and they
promise to develop ‘interoperable
connected products’ within a year, including washers, tumble dryers, dishwashers and heating/ventilation/airconditioning (HVAC) systems.
My guess is that by the end of the
decade, consumers will routinely
sleepwalk into accepting this method
of silently controlling their electricity
consumption. Still, we will have to see
whether ESAs will make much difference to our energy supplies.
Not so economical
There are problems looming for legacy meter users as well. Regular reader
David Platt dropped me a line about
another energy-saving problem he’s
wrestling with:
Being a retired coal power shift operations engineer, I follow your comments about the future progress of new
energy generation with great interest,
especially the advancement of SMRs,
wind, solar and wave power.
I have what is known as a “GEC Radio Teleswitch” (RTS) feeding a Siemens Normal/Low metering device.
Are you aware that in June 2025, Octopus Energy is cutting off the Economy 7 radio signal, which is what my
meter requires to operate properly?
They propose giving me a new-fangled
dumb smart meter instead.
Is this signal cut-off common for all
Energy Providers, or is this just a way
to roll out the Government’s dumb
smart meters? Can we stop the signal
cut-off? Yours, David Platt MIET.
The concern David highlights relates
to the abandonment of the 1980s RTS
long wave transmission, which takes
effect on the 30th of June, after being
postponed from 2024. The LW radio
signal technology is deemed obsolete
and unserviceable, so naturally all
the electricity suppliers (not just Octopus) are pushing smart meters as its
replacement.
Some 600,000 meters are reportedly
affected, and there isn’t really any technological alternative on offer today.
For non-UK readers, Economy 7 and
Economy 10 are cost-saving electricity tariffs that use a radio-controlled
device to switch certain meters to
cheaper off-peak rates, for seven or
ten hours. There is more information
about the RTS changeover at https://
pemag.au/link/ac4i
As far as I know, having a smart meter fitted still isn’t compulsory, but if
you use Economy 7 or 10, you will
otherwise lose the cheap-rate tariff
once the RTS is switched off. Unless
they have a change of heart (which I
doubt), I see no hope of extending the
service. I’m afraid the outlook isn’t
great for consumers who don’t want a
smart meter.
If no smart meter is fitted, the end user
must bear the cost of ripping out the old
equipment and updating his wiring.
David later wrote to say that he had resigned himself to scouting around for a
smart ‘dumb’ meter after all.
When ill winds blow…
We now have the ludicrous situation
of sometimes paying wind farm operators not to generate power (shedding
load) when it’s too windy, while paying end-users of the so-called demand
flexibility service (DFS) not to use
electricity at peak times either.
There are signs that the novelty has
worn off this incentive scheme as, according to the Telegraph, only 750,000
consumers remain in it compared with
two million in the previous year.
Practical Electronics | April | 2025
Britain’s costly quest for renewable
energy is fraught with setbacks. Last
December, the brand new 190-acre,
50MW Porth Wen Solar Farm in Wales,
which was six years in the planning
and construction, sustained severe
damage caused by Storm Darragh
and is already out of service. A nearby wind turbine also self-destructed
because it was too windy.
Such turmoil is likely to get worse
over the next few years, and I reckon
it’s maybe a decade away before Small
Modular Reactors finally come on
stream to provide a stable base load.
EDF recently confirmed that two of
its four ageing Advanced Gas-Cooled
Reactors will now continue operating
until 2027, and the remaining two can
operate until 2030.
The extra toll that electric vehicles
and power-hungry AI data centres will
place on the grid has yet to be played
out, maybe helped by energy-smart
appliance technologies. No-one knows
for sure if wind and solar renewables
will take up the slack in the meantime.
For my part, I’ve stocked up on refills for my picnic stoves and portable heater, and I’ll keep a cupboard
stocked with tinned food and bottled
water just in case!

ica Online (AOL) users started to flood
onto Usenet, trampling on established
courtesies and usage protocols along
the way (“Me, too!” was their oftenmocked catchphrase).
AOL floppy disks and CDROMs
rained down in a way we’d never seen
before, in an attempt to batter potential customers into signing up to AOL’s
fixed-rate service.
As described in the fascinating
Anglo-American book net.wars by
Wendy M. Grossman (New York University Press, ISBN 0-8147-3103-1),
AOL also provided its customers with
a direct route onto Usenet.
The arrival of these Internet neophytes saw early ‘flame wars’ breaking
out online, strictures about ‘net abuse’
taking shape and a general resentment
amongst long-established, ‘professional’ and elite Internet users.
It would be true to say that having an
AOL address made you fair game for
online abuse from intolerant old-timers
or CompuServe users. That’s just the
way it was, as the process of democratising the Internet got under way.
Another Usenet trend emerged, first
noted in about 1993, when cohorts of
‘newbie’ AOL users stumbled online
every time a new University intake arrived each September.
Many of the ‘net’s original unwritten
principles, including observing ‘netiquette’, reading the ‘FAQ’ before annoying people with questions, and the
need to ‘RTFM’ were ignored by those
who neither understood nor cared.
The fact was that the Internet genie
had been let out of the bottle, and everybody now wanted to get in on the
action.
Portal websites, chat rooms, search
engines and messaging systems were
popularised as the Internet evolved at
speed. Early forms of the eBay website
described itself as “the world’s online
marketplace”.
Numerous online brands such as
Alta Vista, Ask Jeeves, Excite and ICQ
came and went, while others, such as
Yahoo! and Netscape, still hang on in
there today. Ironically, AOL eventually acquired CompuServe.
