Energy Management is the actual management of real, energy use. It has to be generated, distributed, stored if possible, stabilised to remove as many peaks and troughs in demand as possible, and ultimately used as efficiently as possible. Pooled Energy does real energy reduction and management.
Tariff Minimisation is a financial activity that superficially may look like energy minimisation, but isn’t. Shifting energy consumption from a printed on-peak to off-peak time can help reduce cost but does not necessarily help with real peaks in demand which, interestingly, often happen during off-peak times: in NSW, on hot February nights for example.
