What the Arab Spring Could Mean For Solar Power in Sahara
- jdwhit2 15y agoThe numbers to build a HVDC line across the desert are pretty good: A HVDC line at 600 kV rated at 3GW (equivalent to supply 1.5 million households) can be built for $8.62 / MWh [1] It is estimated that a solar tower in 2020 be built to produce energy at a cost of $54.7 / MWh [2] The current base load energy contracts in Europe for 2013 are at around $50.3 / MWh [3] If looked at in its entirety, the project cost is overwhelming, but what if a consortium bankrolled only the HVDC link and acted as a Market Network Service Provider. They would charge desert solar farms for network access and earn their return. The same thing is being trialled in Victoria, Australia where wind is plentiful. A single bulk sized line is built to the windy resource area and it become viable for smaller wind farm operators to connect at the end of that line.
