The invention relates to a method for regulating the production and/or delivery of a second energy form generated from a first energy form in a system comprising production units for converting said first energy form into said second energy form and delivering said second energy form, and a market server being communicatively connected to one or more supplier units of suppliers of the second energy form. In one embodiment, the method comprises the steps of receiving one or more data strings with production data from the supplier units by, on or via the market server, which data strings comprise at least two production parameters from the set comprising the demand volume of the first energy form, the supply volume of the second energy form and the conversion efficiency of the conversion of the first energy form into the second energy form; determining on or via the market server, on the basis of the data received, a value for a conversion volume parameter of the production of the second energy form from the first energy form; determining on or via the market server, on the basis of the value of said conversion volume parameter, a volume of the first energy form that is to be converted and a volume of the second energy form that is to be produced; and making accessible on or via the market server data relating to the volume of the first energy form that is to be converted and the volume of the second energy form that is to be produced. The production units that produce and/or deliver the second energy form have been selected by the market server.
