I think that BMLD should consider using more transformers, rather than two 50 megawatt units. This would enable us to match the on-line capacity to the actual load more closely.
Consider the savings in the cost of the iron loss in a 50 megawatt transformer not needed to meet demand:
Iron loss at 0.25 % = 125 kilowatts
Cost at 5 cents per kilowatt hour = $6.25 per hour
Annual cost (8760 hours) = $54,760
This will support more than $1 million in 5% bonds or pay off a 20year, 5% loan of $682,000 or a 20 year, 4% loan of $744,000 .The savings would continue after pay off and Belmont would be “greener”.
Thanks, Marty. This sounds like one you’ll have to direct to BMLD management. Don’t know enough to have an opinion.
