Situation:
- Energy is a large percentage of operating costs
- Competitive industry with narrow profit margins
- Significant refrigeration needs
- Outages have significant consequences (lost sales and spoiled
products)
- Limited available space
Solution: Pre-fabricated system with 2 x 200 cogen units + 110 Ton
absorption chiller
Grocers face a challenging situation. Profit margins are incredibly
tight, many items have a very short shelf life, and some items will be
damaged if refrigeration is lost for even a short period of time. The
addition of increasing energy costs and the threat of rolling blackouts
makes it even more challenging to improve profits.
A seemingly very attractive situation for onsite cogeneration is
confronted with the challenge of finding space for the equipment given
limited space availability. Hess Microgen solved this problem by placing
our packaged cogeneration units and related equipment, including an
absorption chiller, associated pumps, and all other ancillary equipment,
on a prefabricated skid that could be installed above the delivery bay.
By assembling the skid in our factory, Hess Microgen is able to deliver a
nearly complete cogeneration system to the site, resulting in a very
simple installation process.
The system generates 400 kW of prime power, or nearly 85% of the
facility's needs, and 110 Tons of equivalent chilling offset to greatly
offload the refrigeration system. Because the chilling offset lowers the
facility's overall demand, the system's ability to provide 440 kW of
emergency power is enough to keep the entire facility up and running in
the event of a blackout. The result is significant savings from lower
energy costs and avoiding the need to install backup power generation
equipment. Further benefits would result from continued operations during
a utility blackout or environmental disaster.
Hess Microgen's pre-fabricated system concept is indicative of the
innovation and expertise of our team. While grocers are excellent
candidates for this system, it can be adapted for many other uses, from
grocer-like applications such as "big box" retail to any
situation where space is constrained or simplified installation is
desired.
