HVDC: Back to the future

​The future began in Gotland in 1950. It is here, between this island 90 kilometers off the coast of Sweden and the mainland, that the first direct current connection for the transmission of electricity was made. Though limited in size and power, the project has had enormous resonance. In fact, the prototype developed by ABB showed the world that transmitting energy in HVDC is possible. The technology [...]


Dam Safety for Hydropower Development

Hydropower projects can actively contribute topoverty reduction and life quality enhancementin local communities Hydropower is renewable because it draws its essential energy from the sun which drives the hydrologic cycle that, in turn, provides a continuous renewable supply of water. Hydropower accounts for more than 92 percent of all renewable energy generated and continues to be one of the most [...]


Smart grids for preventing blackouts?

​ Transmission adequacy problems versus electrical growing consumptions, control and protection technological ageing, unpredictable renewable sources penetration, unbundling and market distortion effects, lack of coordination between system operators… are just examples of possible root causes which led  to partial or total blackouts in recent years worldwide. USA and European large disturbances on [...]


ORP Potential can enhance flexibility

High operational flexibility (e.g. the ability of a power plant for fast start-up and to adjust load output as a function of changing of market requirement) is an essential pre-requisite to ensure economic success in a liberalized market. Plants under cycling duty are subjected to excursions of temperature, pressure, water flow rate, making very difficult to follow appropriate cycle chemistry guideline [...]


Heading for a Sustainable Energy Future 2050

Extract from the speech of Matteo Codazzi (CEO at CESI) at the 3rd Dii Desert Energy Conference, held in Berlin on November 7th, 2012   The Target Europe is undoubtedly a forerunner in the actions towards a sustainable energy future. Following a debate started in 2007, in 2009 the EU Parliament and Council set binding targets on CO2 emission reduction, RES generation penetration, increase in energy [...]


Volatile RES & Thermal Plants flexibility

Introduction With the aim of reducing CO2 emissions and dependency from fossil fuels, in various countries the sharp increase of electrical RES (Renewable Energy Sources) as a result of policies of substantial subsidies is creating problems to an efficient and reliable operation of the electrical power system. Both transmission and distribution systems have to face an increasingly variable production [...]
