You asked "Morgan should calculate the electrical energy (kWh)
generated by Point Lepreau since it went into service and what it sold
for."
Nucleonics Week (Feb 14 2002) lists Point Lepreau as having
generated 95,425,411 MWhe (gross) to Dec 31 2001. This probably does not
include the pre-commercial electricity generated over the few months during
the commissioning stage (Point Lepreau first went critical July 25 1982, was
first synchronized to the grid on Sept 11 1982, attained first full power on
Dec 18 1982, and was declared in service on Feb 1 1983).
The net generation (electricity delivered to the grid =
gross electricity - internal use) is typically 93 to 94% of the gross
generation. I have used a value of 92% for several years, and have
consistently used this so as not to exaggerate the net electricity. Thus
Point Lepreau has delivered (since being declared commercial until Dec 31
2001) at least 87,800,000 MWhe to the NB grid. My Manitoba house (all
electric, including heat but no air conditioner) consumed about 20 MWhe per
year (dependent upon the severity of the winter), so Point Lepreau's
electricity would have powered my house for about 4.4 million years (or 4.4
million similar homes in similar climates for one year). A typical
Canadian home consumes 10,320 kWhe/year, according to the Ontario Clean Air
Alliance. Thus Point Lepreau's net generation is equivalent to that
required for about 8,500,000 typical Canadian homes for one year. There
are also grid losses, which are a function of things like distance and
voltage, but these are found for all generation sources.
As to the value of the electricity, I can only estimate
it. Ontario Power Generation sold its electricity last year for an
average of $0.042/kWhe. Assuming the same value, Pt Lepreau has
generated electricity with a present value of ~$3.7 billion.
