Automation Delta Steel Mills factory, Cairo, Egypt

Implementation of power management system, based on programmable automaton network, allowing data acquisition and measurement, as well as the capacity to automatically act on charges so as to eliminate over shoot and maximize the production, while reducing the average factory consumption.

Automation and energy consumption management, National Metal Industries, Cairo, Egypt

Implementation of a power management system, based on programmable automaton network, allowing data acquisition and measurement, as well as the capacity to automatically act on charges so as to eliminate over shoot and maximize the production, while reducing the average factory consumption (1995-1996).

Implementation of a power management system, based on programmable automaton network system (PLC) to centralize and continually manage the global electrical demand at the mill.  The system allows the distribution of a call between two electrical sources.  It also allows the delestation of appropriate furnaces to reduce call peak and therefore, increase the mill's profitability level (1995-1997).

National Master Plan - Rural electrification, Haïti

Preparation of a national master plan identifying investments for electrification to be made until the year 2005.  The electrical energy sub-sector in Haiti has been the subject of several aid programs for the last ten years but mostly in the metropolitan area of Port-au-Prince; the electrification of villages and rural areas is low.  The national master plan identified investments required over the next 20 years to progressively allow the different regions and adequate supply of electricity.  The main steps comprise: a study of the present situation (government policies, existing facilities, Ed'H personnel, electricity rates, financial results of Ed'H, outside financing, resources, profitability, quality of service, discount rate), a socio-economic study and demand forecasts (demographic and economic growth, cost of electricity, competition from wood charcoal, use of home appliances), a study of electrification plans (generating stations, transmission and distribution power lines, interconnections, investments in 5 year programs), rate studies and financial planning (financial evolution of Ed'H in view of the proposed investments, changes to the electricity rates, financial forecasting) to finally arrive at the preparation of the National Master Plan, which has been designed to be easily updated. The organization and the functioning of the planning department of Ed'H and of the associated ministries was analysed and recommendations has been prepared.  Then the methodology, the data obtained and the models used during the preparation of the master plan has been transferred to Ed'H.
