RE: Terra-Gen Power closes funding for 'largest ever' wind farm
The article SHOULD read "The State of California estimates that it requires 55,657 gigawatt-hours / YEAR of new renewable energy generation"
The 570 MW of CAPACITY that they are planning to install is a measure of the INSTANTANEOUS generating capacity of the farm.
Since there are 8,760 hours a year, the maximum power generation of the farm would be 8760 hours/yr * 570 MW = 4993 gigawatt*hours/yr
But, this is assuming that the wind blows at full speed every hour of the day for the entire year. To know the actual power generated by this farm, you would need to know the wind velocity characteristics for the site, in addition to the part load performance of the turbines being installed. A better estimate would be about 1/10 to 1/3 of the maximum value, or 500-1500 GWh/yr
