d. Generation for own use
While the generation of one’s own electricity is a novelty in the modern electricity grid, it has historically been the standard way of provisioning energy. The immediate use of self-generated electricity is arguably the most well-known form of prosumer activity.
Generation for own use is a form of negative generation, as it allows a market player to reduce their energy intake from the grid, while leaving their own level of demand untouched. As the generation from distributed renewable sources tends to be variable, it is often combined with another form of prosumer activity, such as energy storage or the possibility of selling excess energy to the grid.
