Today is a hot day. It is hotter than yesterday, which was hotter than the day before.

This would be a good time to analyze real data to see how Delmarva would perform with Bluewater Wind supplying our power, against how it would perform without Bluewater Wind supplying our power.

Anyone with good eyesight and a sharp mind can go to this site to find out how much money our power is costing our supplier each hour of every day. They can see that during the hours between 2 am and 6 am, that the power actually dipped cheaper than that supplied by Bluewater Wind in its PPA…. That price (bundled) was around $105 dollars per MWh. For the other twenty hours of the day, the bought price was higher. At one point, during the afternoon, it peaked at $378 dollars per MWh…. which is a pittance when compared to $105 dollars per MWh provided by Bluewater Wind. (snark alert….It is actually $273 dollars per MWH more expensive.)

Side Note: It is important for all Delmarva customers to understand that what they pay, is an average of all these prices over a month, averaged together….. But if you clicked the link and looked at the data, you would see that unless our Public Service Commission was actively monitoring this data and imputing these calculations into a calculating apparatus….. Delmarva could charge us whatever they wanted, and who would know?…… Let us make sure that office never sees budget cuts, huh, as is part of Charlie Copeland’s cost cutting plan….

So how does Bluewater Wind play into this equation?

The more Bluewater Power that Delmarva is forced to buy, the less of the $378 dollars per MWh during peak times, will be passed on to us……

So how much would that be?

Remember the argument that wind does not blow in the summer, when power is desperately needed?

Todays data from NOAA provided at the location where the proposed wind farm will sit….directly east of Indian River inlet, approximately 11 miles out……

On this day, June 10th, 2008, winds will range between 5 to 10 KT, becoming 10 to 15 KT late…

Using a GE 3.6 MW Series Wind Turbine (one made in the USA), each turbine would generate from 6 mph to 17 mph (the equivalent range of 5 to 15 KT’s) between .4 and 3.5 MW over the day’s stretch.
Now if we want to find a base level, we take the least amount: .4MW and do our calculations with that figure….

If each turbine of the wind farm is working, the low point of our day would be a collective 40MWH if we assume a base number of 100 turbines in operating mode… remember that is our low point… For reference only, on this slow doldrum of a day, our high point would be 350 MWh of electricity, more that adequate for the 300 MWh to be provided to Delmarva according to the ironed out agreements in the Power Purchase Agreement (PPA).

Therefore, 40 MW of energy would be provided to the grid at a cost of $105 per MWh, instead of the current zero amount we have now… If we take PJM’s entire grid’s previous peak demand’s all time high of 144,644 MW (August 2, 2006) the measly 40 MW added to the grid, is a whopping 0.002% off our peak demand for which we collectively are to pay $378 dollars a MWh for the privilege of staying cool.

I do this to show that when it comes to windpower, more is cheaper than less….Any attempt to whittle down our windfarm will increase our electric bill higher each year….

Now at a 15 KT (or 17.5 mph) winds predicted for today….the 350 MWh generated (300 MWh of which will come to us, would increase the savings factor by a power of ten, and represent 0.002% of the peak demand total…

What impact does that do for the price?

Get ready for some big numbers….

144,644 MW x $378 dollars/ MWh = $54,375,432 dollars / hour

minus 350 MW x $105 dollars/Mwh = $36,750 dollars / hour

The amount saved would be a difference in the two rates $378 versus $105 times the number of Bluewater hourly MWh which according to the PPA will be 40 MW. Bluewater wind, in the worst case scenario, on the most expensive day, will save $10,880 an hour…..not a cost, mind you…..

Every other single day of the year, for the next twenty five year life of the contract, Bluewater Wind will save us much, much, more….
