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 […]
