Should the VRE in one region have tow output, other regions experiencing overgeneration can transmit excess electricity. In 2009, Germany produced 592 TWh of electricity3, which gives an average power consumption of about 826 W per capita4, implying that a city of one million inhabitants needs on average nearly 1 GW of electricity supply, with considerable variations. The highest capacity transmission project being constructed is for the capacity of about 7.2 GW of high voltage direct current (HVDC) overhead line5, which could sen/e a region of about ten million inhabitants. Transmitting hydropower over long distances is common in Brazil, China and India, due to inexpensive electricity and remote locations of hydropower. Current electricity storage capacity is usually nearly negligible in comparison to instantaneous power generation and due to nearly instantaneous power transmission.
