Historical Rate Inflation in NY
The figure to the left
illustrates the
increase in electricity
prices in the
commercial sector in
New York from 1970
to 2007. The
compound annual
growth rate over the
period is 5.0%.
A forward modeling of the historical New York commercial sector rate data indicates that the
average compound annual growth rate over a 20-year period is 5.1%. The analysis shows a
75% probability of experiencing a CAGR of 3.6% or higher and a 25% probability of
experiencing a CAGR of 6.4% or higher.
Probability of Savings
The figure to the right
illustrates the
probability of savings
over the 20-year term
of a PPA outlined with
the noted parameters.
The figure shows a
100% probability of
customer savings, with
a 50% probability of the
customer saving at
least 39% compared to
a base utility case.
The figure to the left
shows the probability of
savings for the terms of
the sample 20-year PPA
for a commercial sector
building in New York.
The host site would
have a 75% probability
of seeing savings of
$334,396 and a 25%
probability of seeing
savings of $755,664
over the 20-year term of
the PPA.
