This is the e-mail I received this morning from Jenn regarding the questions I posted earlier:
1) Usually, fiscal years.
2) I'm not sure I'm following the efficiency question. You should count
the steam you use in the plant as part of the total steam output. And in
determining the steam production efficiency. Default values for co-gen
efficiency from the EPA's Climate Leaders program are eH = 80% and eP =
35% (where H=steam and P=electricity - see
if that helps any...
Hope that helps; if not feel free to email back or call: 603 475 3587.
