Peakload
Shaving, PeakShaving, and PeakShave are terms used by
utility companies. As outlined in the article
Overview of
Products, Concepts and Technology used by Alternate Energy
Systems, Local
Distribution Companies (LDCs)
purchase a certain amount of gas over a fixed period of time
(per day, per week, per month, per year, or sometimes even
per hour). However, even the best laid plans cannot take
into consideration unexpected cold spells, a burst pipeline,
or other events that could happen to disrupt the planned
quota.
If the LDC
should need more gas than it has contracted, they pay a
premium price – if the gas is available, to begin with. So,
to insure extra gas and avoid paying a premium price for any
gas above the contracted amount, many utility companies use
LP, mixed with air, to duplicate the properties of NatGas.
This mixed gas is then used to supplement the LDC's gas
supply, removing peak NatGas flow rates, and thereby
allowing a more consistent fuel rate from their supplier,
and help meet peak demand loads.
PeakShaving
Plants have been around for a long time, and a large number
were installed in the 1970's. Unfortunately, many of them
show their age with respect to automation, remote
monitoring, gas properties control, maintenance intensity,
safety, reliability, ease of operation, etc.
The
PeakShaving Plants manufactured by Alternate Energy Systems
are typically designed and manufactured to meet the specific
needs of a particular customer. However, they all have a
number of features in common: |
