2700 MW @ 25% average capacity factor = 675 MW electricity delivered on average to the ISO NE grid.675 MW divided by average ISO NE grid demand of 16,000 MW = only 4.5% of grid demand will be met by 2700 MW of wind turbines.Cost of Wind Generated Electricity2700 MW x $2 million per MW construction...

By Christine Smith The gales have died away to a steady wind and at last the rain has stopped. The silvery lines of the drainage channels carry away as much as they can but still there are pools of standing water everywhere. Beyond the sound of the wind is the constant muted roar of a sea no longer wild but still powe...

The previous analyses assigned wind a capacity factor of 28 per cent, which may not be achievable for a number of reasons, for example: reduced availability of good wind sites as wind penetration increases and curtailment of wind production, particularly in high wind periods, by the sy...
