How much money does a 2.5 MW wind turbine make per day?

Question

assuming 100% effeciency and 6 cents per KW/H

Answer 1

how many hours are in a day?

i get 24 h

2.5 MW is how many kW

I get 2500 kW

2500 kW * 24 h  = 60000 kWh

ok now multiply that buy the price.

60000 kWh * 0.06 $/kWh = 3600$

so it makes 3600 dollars.

Answer 2

In this problem, efficiency is largely irrelevant, as the turbine is rated on *output* electrical power. Efficiency is (electrical output power)/(mechanical input power) If it's a 2.5MW wind turbine, its output capacity is 2.5MW regardless of the input power.

However, you will need to consider capacity factor. The capacity factor is the ratio between the average output power of a generator, and its maximum capacity. Because the wind does not blow at a constant rate, a wind turbine does not have constant available prime-mover power. It cannot generate more than its rated power, but it can generate less. Estimates of the capacity factor of wind turbines range between 7% and 30%.

Then, you must consider whether the income you are calculating is net or gross. For the wind turbine to be considered to be "making money" in isolation from the overall generation portfolio, one must presume it is connected to one of the deregulated electrical grids as a market participant of some sort. Normally, then, it will be subject to some contract whereby it has to pay for the use of the transmission system that it connects to, and may in addition pay a surcharge for any losses or congestion that it causes. It will also generally be paying either a land-use fee to the landowner where it is situated or, if owned by the land owner, and aggregation fee to the operator of the collector system to which it is connected. Transmission usage fees are usually based on a proportion of the power generated, while land-use fees are usually a flat rate.

So your calculation will be:

C=Capacity Factor

T=Transmission access charge($/MW-hr)

L=daily land-use fees ($/day)

Net income per day = C  * 2.5MW * 24hr/day * ($60/MW-hr - T) - L
