Does anyone know what the "$1/Watt" figure is supposed to mean?
"And it will make wind cheap – $1 per watt, installed – for the first time ever, with the 250,000 kWh machine to be priced at $250,000."
- kWh are a measure of energy, not power. (1 kW sustained over 1 hour) Are they saying the turbine's lifetime is limited generating that much energy?
- The paragraph above implies that the cost is $1/kWh - somewhat more reasonable than $1/Wh. Although that's still more (~3x) than I'm paying for my electricity right now.
Alternative theory: what they mean is the turbine generates up to 250kW under ideal conditions, and costs $250k to set up. That would mean the $1/Watt figure is about setup costs. (depends on the amount of required maintenence whether that's an interesting number)
- ovi256 18y agoYour alternative theory is right. What they mean is that the turbine costs $250k retails, setup costs excluded. And these will add 10% easily - foundation, electrical network link etc. And the turbine generates 250kW of peak power under ideal (right wind) conditions. So the $1/W figure is, as you say, a one-time cost. Maintenance should be pretty low however.
