We had a really interesting Smart Grid related conversation with a company called Arqiva the other day.
I hadn’t heard of Arqiva before but they are quite a significant player in communications infrastructure. They own or have exclusive marketing rights for 16,000 communication masts in UK – what they call vertical real-estate! They also own, operate and maintain all of the UK’s terrestrial television network as a regulated monopoly. And they are responsible for rolling out the switch-over from analog to digital broadcasting for the country.
If that weren’t enough Arqiva are Europe’s largest provider of satellite linkage services!
All very well I hear you say, but what does this have to do with Smart Grids?
Well, Arqiva have a fascinating proposition. They are expecting Ofgem (the regulator for the electricity and gas markets in Great Britain) to announce some kind of central procurement for a Great Britain-wide network and if that occurs, Arqiva would be in a very strong position to bid for it.
They have dedicated UHF spectrum (412 MHz) and a nationwide mast footprint already capable of reaching 100% of the homes in the country. A significant advantage of the dedicated long range spectrum (apart from the lack of contention) is that it will have no problem reaching into houses where meters can be located under stairs or in basements, for example. Cellular networks don’t have the same luxury and are more plagued with health concerns around the transmissions from their masts.
Having a single provider of the communications infrastructure for smart grids is a very appealing proposition – especially if it has regulated returns and contestable pricing which you would expect in a system like this.
Arqiva announced [PDF] just the other day that nPower is joining Arqiva’s Smart Grid proof-of-concept network which covers 80 square kilometres around Reading. nPower are a significant utility with around 6.5 million residential gas and electricity accounts throughout the UK. This will allow Arqiva to test smart gas as well as smart electricity meters and they ultimately want to include smart water meters in their network as well.
Arqiva say they have thought about security as well (which is just as well seeing as a single communications network for electricity, gas and water makes for an extremely attractive strategic target). They are using encrypted communications over licensed spectrum, and are operating a closed system so that should help but security is a constant battle so it is one they will need to stay on top of.
If Arqiva manages to roll this out successfully in the UK, this will leave them in a very strong position to reproduce this model in other countries.

Hi Tom, we’re glad you found the conversation interesting. There are just a couple of quick factual things that we wanted to clarify. Arqiva is proposing a long range (not long wave) radio solution using our dedicated licensed UHF spectrum. Also, while Arqiva has a marketable portfolio of over 16,000 sites, only 8,000 of these are currently active. The others are available for use as and when needed by Arqiva’s customers. Thanks.

Stephen, thanks for the clarifications. I have changed some of the wording of the post to reflect these.
