the customer charge is per day per meter station at $6.136, not related to Therm
or CCF. Distribution charge is per MCF per day, GCA is determined by a
complicated equation of projected cost over projected sales plus something
minus something. This is not helping you, but the point is that
different utility company has different rate
structure. </FONT></SPAN></DIV>

[Bldg-sim] gas: Btus to cost via pricing scheme<BR></FONT><BR></DIV>
<DIV></DIV>Hello Cramer,<BR><BR>An colleage of mine and I did some recently did
some research on Natural Gas prices for New York State, and we banged our heads
against the wall for a fair bit before figuring out how these rate structures
fit together. The two of us just took a look at what you listed below and
here's our best guess. <BR><BR>Customer charge is the monthly
base<BR>Distribution charge is likely the "delivery" component charged on a "per
therm" or "per ccf" basis<BR>Cost of Gas Adjustment is likely the "supply"
component charged on a "per therm" or "mdcq" basis (not sure what mdcq is, but
it seems to me that only one of these two lines applies to the actual bill,
depending which unit you are billed in (therms vs. mdcq) <BR>Local Distribution
Adjustment Charge is likely another fee they tack on per therm, ccf, or
mdcq.<BR><BR>So.... if you were billed in therms, I believe your total bill
would be 550.41+(1.0322+0.8651+0.0491) * Therms usage. <BR><BR>Hope that
helps!<BR><BR>Best,<BR>Andy<BR>-- <BR>Andrew McNamara, LEED AP<BR>Bright Power,

<DIV><SPAN><FONT face=Arial size=2></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial size=2>I'm trying to take my gas use output
numbers (Btus) and calculate the cost of the gas using the pricing scheme from
the local utility (Keyspan in Boston) for a LEED certification. However, I
can't figure out what the scheme means. Can someone tell me what these numbers
mean, in terms of how to write an equation to take my hourly outputs of gas
use (from Trnsys, but I'm doing this in Excel) and calculate final
(monthly) cost?</FONT></SPAN></DIV>

<DIV><SPAN><FONT face=Arial size=2>I've gone to the utility's website and
found this data, but nothing to explain it, nor anywhere else on the web. I
called them, and just get passed around their service department because no
