Power Protection and UPS Blog

The Portugeuse Moto GP proved an all round winner for Riello UPS last weekend. We had over 70 people from across the world attend the weekend in Lisbon and Estoril. It wasn’t all bikes though. The weekend was split between presentations on Saturday about Riello and the new Multi Plus UPS, a special banquet on Saturday night attended by Ducati personnel and followed by a full day at the race track on Sunday. Whether you were a motorbike fan or not, the whole weekend was an absolute winner for all concerned.

I was reading yesterday about how the UK Government has been ‘blue-skying’ the future of energy - Nuclear or Wind Power? Centralized v distributed supply? It got me thinking about the future of UPS and I decided to do a bit of blue-skying myself:

Examine any technological innovation over the years and what usually happens is that all efforts, once it has been invented, turn to ‘miniaturization’. UPS is no different. The uninterruptible power supplies of the future - even in huge industrial applications - will be tiny in comparison to today’s units. Transformers, inverters, filters, conditioners, fans and all internal elements in a UPS are being continually downsized.

Alongside an increasing upsurge in demand for energy, ‘income-per-squarefoot’ is something business managers are trying desperately to increase, which is why essential equipment like UPS needs to be smaller, take up less space, be more energy efficient and at the same time more sophisticated, faster and better than before.

The challenge for us as UPS manufacturers in blue-skying the future is to develop products that meet these demands whilst at the same time ensuring reliability, quality, innovation, resilience and ease of use. To me, the best definition of progress is development towards an improved or more advanced condition. So, to borrow the phrase from a well-known advert - “more forwards please…………….”

As technology converges to Power over Ethernet (PoE) and VoIP, there is a far greater need for power filtering, conditioning and surge protection, which you typically get from UPS installation.  

As an enterprise technology, Ethernet has resided inside a building where it only has to contend with minor surge-related issues like cable discharge and disconnect events. PoE expands use of the technology and takes it outside to security cameras, WiFi access points, or fiber-to-the-home. Suddenly it becomes more prone to lightning and other, more serious, surge-related issues. In emerging countries like China, Russia, or India, were power is not as tightly controlled as it is in Western Europe and North American, serious power surges can be a real problem.  

An effective UPS solution will contain filters and frequency conditioners that shield and protect upstream equipment and loads from power quality problems. But power protection should always begin with a power quality review to asses the actually quality of mains supply and the level required. This should also include future demands, sources of alternative power on site and priority-based load shedding and shutdown.  

For more information on power quality issues and how they can be addressed through the strategic use and implementation of UPS, see The Power Protection Guide, written by Robin Koffler and Jason Yates of Riello UPS and published by entiveon, or visit Riello UPS at Uninterruptible Power Supplies (UPS) - Riello UPS Ltd - Power Protection.

According to this week’s news, it’s doom and gloom for the future of food. We’re running out of wheat, rice, soya - and  curry Chefs!

That last one’s a real problem for me (he says jokingly)! Apparently, changes in the imigration laws in the UK (in particular), are making it difficult for Indian restaurants and Balti houses to source genuine, authentic and experienced cooks! Yikes! 

As far as grains and pulses go, climate change and global warming are being blamed for poor harvests around the world but an even darker threat is lurking just around the corner. Yes, you guessed it - Biofuels!

The Energy Independence and Security Act of 2007, which became law in December, mandates the use of 36 billion gallons of biofuels by 2022 and almost half of that will come from grain-based (corn and wheat) ethanol. In North American this is great news for the corn-growing states that will now, I fear, intensify production but not for food for fuel, easier to produce, less regulated and (I imagine) more profitable. My worry, which I have touched on before in this blog, is that food production will suffer at the hands of politics and capital gain from Biofuel production where it is being produced to replace fossil-fuel derived products (Petrol and Diesel) for vehicles.

What has this got to do with power protection? Well, firstly, did you know that the processes currently used to produce ethanol are energy intensive and thus add to, not negate, the issue of increasing demand for energy? Secondly, biofuels are being used in fuel cells, which can replace UPS batteries as an alternative back-up source. The technology is available now and whilst the origins of the fuel may be questionable, they offer a number of key advantages: harmless emissions, longer design life, less maintenance, reduced heat output and in many cases cheaper lifetime running costs.

The Power Protection Guide talks about fuel cells and their use in UPS installation.

Did you know the UK’s National Grid (and I should imagine most other energy utilities the world over) employs a team of people who do nothing other than demand forecasting?

Electricity is one of those things we take for granted. You come into the office, switch on the lights, computer, kettle and - hey presto - it all works! Simple! So why a whole team to manage and forecast demand? Well, too much electricity entering the Grid can cause problems like overloads, circuit-breaker tripping and even blackouts. Too little and the frequency of supply falls, causing sags and brownouts. It’s great that we can sleep at night knowing there is someone out there taking care of all this so that we don’t have to! Or do we?!

With demand for energy so high and supply increasingly challenged, isn’t it time, particularly as business people, we started to adopt a more proactive stance towards energy consumption?

Measuring true electricity usage, particularly by businesses, is not straightforward but nor is it rocket science. There is a science to it, which, with a bit of professional guidance is within the grasp of most business professionals. But imagine what you could do armed with that information? Firstly, you’d have greater ability to consolidate you energy bills with your supplier and get a cheaper rate perhaps. With a better idea of peaks and troughs in consumption you could even consider money saving initiatives like ‘Peak Lopping’, which is a way of reducing energy bills and securing supply during peak times. It is the practice by which the user has a contractual agreement with their energy supplier to switch from mains to back-up generator during peak periods. In return for this ‘interruptible’ supply, the user gets a significant reduction in their energy bill. A by-product is that the power continuity plan, UPS and back-up supplies are being utilised and tested under load conditions. And if you have an accurate graph of energy consumption, you will have an accurate idea of power protection requirements in terms of sizing your generator and back-up UPS.

At the moment, most companies are happy to leave this in the hands of their utility supplier to ‘guess at’ and manage but how do you know that their ‘assumptions’ or readings about how much energy you use are accurate and that they have your best interests at heart? The time will come I believe - and in the not too distant future - when demand forecasting and energy consumption management will be mandatory practice for big business. But you might as well start now so that when it does happen, you’re ahead of the game.

I was disappointed to learn that the UK’s first Energy Saving day ended with no noticeable reduction in the country’s electricity use. Disappointed but not wholly surprised.

E-day, which started at 1800hrs on Wednesday 27th February 2008 and finished at the same time on 28th was supposed to encourage people to switch off electrical devices they did not need but instead National Grid recorded a 0.01% increase in electricity consumption despite the event being backed by campaign groups such as Greenpeace, Christian Aid and the RSPB, plus major energy companies EDF, e.on and Scottish Power.

I’m not surprised it was a flop for several reasons; firstly, it received little publicity. Secondly, why schedule it in the middle of winter and in the middle of the working week!? Other than not leaving the TV, or other electrical equipment on standby, what devices, machinery or equipment can people do without during their normal working life? It is a symptom of modern society that everything is powered by electricity and most professionals and businesses are unable (and unwilling) to go back to manual operation.

Thirdly (and this is contentious one), I believe that saving the planet from global warming is too big an issue for people to swallow and is therefore not the right one to ‘incentivise’ them to save energy. Of course, I care about the environment (many of my blog entries lay testament to that) but I believe people’s apathy towards this event is very telling. Do they really believe it’s possible to save the planet? Or, do most people feel it is too late anyway, the damage has already been done? The pleasures of living in an ‘always on/always connected’ world are too strong to worry about tomorrow. Some people think saving the planet is not up to us but in the hands of ’the Gods’, a religious icon or ethereal power?

I believe the best and only way to ‘incentivise’ people, particularly business people, into saving energy is through the wallet. Make the core issue saving money and the secondary issue about the planet and you will more likely motivate the masses. Environmental issues are far more of a pr story than money saving ones but the people behind such initiatives as this need to ask themselves why they are doing it - is it really to save the planet or to get publicity? and there lies the rub I fear.

At Riello UPS we take energy saving seriously from an environmental perspective and economic one. Many of our customers, particularly large data centres, are demanding that energy saving innovation be incorporated into UPS technology and we’ve responded by designing units with low input current distortion, maximum input power factor, progressive rectifier start-up and battery care systems to optimize performance that will all combine towards savings in running costs and total cost of ownership over the lifetime of the product. We feel this is a practical step towards saving the planet.

I read with interest on Guardian online that Britain’s oil and gas companies, including BP, Shell and British Gas which recently announced record profits, are saying they need improvements in tax breaks if they are to meet higher production targets in the North Sea.

On the one hand, in my view, it seems they are holding Britain (and every energy consumer in the country) to ransom; ‘give us the economic incentive or we wont invest in North Sea Gas!’. But if we can’t produce enough Gas at home our imports will have to increase and that, I think, is bad news. We have little or no control over foreign supplies, which could be affected by political, economic or regulatory issues beyond our control. We can’t influence continuity or security of supply nor pricing. I think for these reasons Britain’s energy companies should be given some incentivising tax breaks to protect our North Sea interests. Of course it’s a contentious issue and one that will run and run but how else are we supposed to compete on the world stage if we do not protect, or invest in, our own energy assets? Limited as they are we need to keep them operational.

I was asked to write an article last week about choosing the right UPS provider and it got me thinking about all the issues  to be considered as well as the all important price. Too many business managers are forced into selecting on price when doing so could actually cost more in the long run if it results in a less than perfect installation. Does the provider understand the mechanics and characteristics of your business, for example? There is a vast difference between protecting the critical systems of a healthcare establishment and a retail operation, for example. Do they add value to the installation by offering consultancy, site surveys, extended warranty, monitoring and maintenance, and so on, which reduce the overall running costs and total cost of ownership of the equipment? Does their culture match yours? Will you find their engineers lounging about reception, smoking and loudly regaling about last night’s football or will they be smartly but appropriately dressed, polite and professional whenever they are onsite?

Price, of course, is important but it should reflect criticality of the installation as well as value for money from the UPS itself and the benefits of the long-term partnership that the provider brings. UPS is critical to continuity of operations in the event of a power failure. It, therefore, needs to be given the same consideration as any other critical equipment in my view and a provider chosen because of their knowledge, sector expertise, ability to add value and product innovation.

I feel short-changed, having read the specifications and code of practice of the new business continuity standard BS 25999 from BSI. As I mentioned here the other day, problems with mains power supply are far more common than most potential disasters. Incidents of interruption in electricity supply stood at 21 million in 2006 (according to a DTI report), other disasters (such as fire, flood, terrorism, public disorder and so forth) combined could not reach that total. Securing electricity supply is not merely about installing UPS, as with BCM it requires a well thought through and planned out strategy and this is not mentioned once in either the code or specification.

I do not wish to appear to knock the standard. It is, in my view, long overdue and much needed. But I feel that by not specifying a power continuity strategy, it is left wanting. Without electrical energy there would be no business continuity for most businesses and operations. That is a fact. It should, therefor, in my view be a central theme for any BCM strategy and therefore mentioned in BS 25999.

If you want to know more about what constitutes a power continuity strategy read The Power Protection Guide.

With this year’s DataCentreWorld conference and expo approaching, I’m reminded of the difference an uninterruptible power supply (UPS) footprint can make in a data centre where every square metre must earn its keep. Had you noticed how much data centre development is happening in The Channel Islands – well, as much as pressure on building land and the constraints of a few hundred square kilometres of beautiful sea-worn rock allow! As well as the usual resilience and power imperatives, one particular comms multinational was set on the smallest possible UPS footprint. And not just because space was tight either; this particular ‘big ask’ was driven by their awareness of the commercial benefits from a 35% space saving realised by their chosen power protection installation. It’s easy to focus on savings – in this case space. But how much more positive to take a bullish gains perspective instead – and imagine the customer’s delight on realising how many more revenue-earning client racks they could get into space that might otherwise be filled with essential, but bulkier, UPS kit. It’s a salutary tale and one I’m sure I’ll re-tell more than once as I leave my footprint in Barbican Hall 1 next week.
