Elecrical Consumption

I work part time in a small cafe and we continuously find ways on how to save energy. In the kitchen itself we have lots of electrical appliances also other electrical equipment outside the kitchen. We have done everything from metering our consumption, changing ineffective tools, upgrading the insulation, etc. Now my question is, is there a company or a service provider that will help us manage our energy consumption. I have heard of this but I’m not quite sure on how it works or where we can find this kind of system. Do you have any experiences regarding this?
