Uncle $cam points to a scare story about the Smart Grid: Smart Grid: Government spying targets Rural America
Smart Grid is closely related to the National Animal Identification System (NAIS), and both programs are designed to spy on Americans. Even more disturbing than the purpose of these government-condoned intrusions into our lives is the fact that the Obama Administration feels that Smart Grid is so important that it had to be funded in the stimulus package—which is supposed to be used for emergencies only. What’s the emergency? Why does Smart Grid need to be implemented within 60 days of the bill passing?
Oh boy.
I have been working on 'smart grid' or 'intelligent grid' stuff for this company – a German electricity provider that is a leading force in alternative energy projects. In short: Smart Grid is a system to balance decentralized electricity production with decentralized consumption.
Today big electricity production plants generate electricity and small entities, companies and households, consume it. As daytime usage is far higher than nighttime usage a lot of expensive central generation capacity is only used part time. Another problem is that today's electricity distribution network has significant transport losses due to long distance balancing.
In future we will still have some big electricity production plants but also lots and lots of smaller and decentralized ones – be they from wind generators, photovoltaic systems on single home roofs or biomass generators on farms. We will also see innovations in energy storage especially for cooling, heating and for electric cars.
To optimize such networks one will want to provide some control instance that can coordinate the distributed generation side and, as far as possible, also the consumption side. Additionally local generation should be balanced with local consumption to lower energy transport losses.
Photovoltaic generation only works when the sun shines, peaks and droughts of wind generation are more or less unpredictable. Traditional air cooling needs a lot of electricity over the day, electric heating in the winter too. In average we therefore always keep a lot of overcapacity in electricity generation for which costs all electricity users have to pay.
Now imagine a cooling/heating systems that generates cold or heat over windy nights from wind generated electricity, stores it for some hours and releases it as needed in daytime. Then have a centralized control that manages that to minimize the total peak electricity generation and transport need. Imagine a system that is intelligent enough to control the future 100,000 electric cars in a city plugged in to reload between 10:00pm and 10:15pm in a way that minimizes their peak loading need. Without a control system all cars would start reloading immediately when plugged in and the peak capacity needed to handle that would be quite big. But if 10,000 cars start loading immediately, the next 10,000 half an hour later and so on, the peak need will be much less. With a 4 hour loading period per car at no time more than 50,000 electric cars would load at the same time. The peak capacity need would be halved.The price to load up would be less than otherwise.
To be able to manage that the electricity network will need an additional communication layer (this was my part) that is able to manage the decentralized items according to their needs.
There is nothing nefarious about that – the forming standards to do these things will be open. Of course such a system could get abused to snoop on everyone's electricity consumption habit. Every system can be abused. But we have laws or are at least supposed to have laws which prevent such.
And what has a smart grid to do with the National Animal Identification System which tags livestock animals from birth to death to be able to trace back diseases?
Absolutely nothing.
Europe has such an animal identification system using ear tags for about 20 years. When "mad cows" with BSE were found the system enabled the authorities to find the source herd pretty damn quick. Mandatory animal tags also disable farmers to evade taxes by selling unregistered animals. That is the real reason why some of them hate them. Why pay taxes?
There are many such scare stories out there about useful technology and effective government plans. It's good that Uncle $cam posts such stories here. There are really some issued out there to be paranoid about and he helps us to watch out for them. To sort them out is not always easy. But 'smart grid' and NAIS do not really belong into that category.
Somehow the U.S. seems to have more people concerned with such issues than other countries. I often wonder why that is the case.
