This a photo showing a lorry loading diesel into the underground tank. Which is used to run the generator during the power cut. Ascendas, A international IT park which provide 100% power back up(Ref brochure: http://www.ascendas.com/images_common/cms/business_space/86/Brochure_ITPC.pdf). This is to show that even during power cut the A/c. are running with the help of generator. I am just wondering what quantity of diesel is used during power cuts...?. ultimately what's the temperature out put?. This is not only in Ascendas all IT parks, Shopping mall, Business establishment Etc.
