In a competitive electricity market environment, power producers and consumers need, on one hand, accurate load and/or electricity consumption forecasting tools. These tools will ensure an a-priori knowledge on the amount of energy needed for production. On the other hand, forecasting electricity prices, may play a very important role for producers and consumers when planning bidding strategies, in order to maximize their benefits and utilities, respectively. This paper will address both issues in a newly deregulated Algerian Market, with an analysis of the electricity national demand. An example of electricity demand model will be presented, as well as an attempt to introduce price modelling taking into account that there is only one electricity supplier on the market. Possibilities of price forecasting in a deregulated market may be projected
