In this paper, we survey 82 papers related to revenue management and dynamic pricing of electricity and lists future research avenues in this field. Dynamic pricing has the potential to modify electric load profiles by charging different prices at different demand levels and hence can act as an effective demand side management tool. There are different forms of dynamic prices that can be offered to different markets and customers. Forecasting of demand, and demand price relationship play an important role in determining prices and helps in scheduling load in dynamic pricing environments. Consumers' willingness-to-pay for electricity services is also necessary in setting price limits. Elasticity of demand is an indication of the demand response to changing prices. Market segmentation can enhance the effects of such pricing schemes. Appropriate scheduling of electrical load enhances the consumer response to dynamic tariffs.
