Better Protected Through Measuring Energy Consumption
Friday, March 7th, 2008
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.
