Press release
Abattoirs rank among the most utility-heavy operations in the agricultural industry, with electricity, water, cooling and heat being in high demand throughout the year to keep these facilities running. The sprawling operation belonging to Meyerton-based pork products supplier, Lynca Meats, is a notable case in point, where finding the most effective means of containing operational costs remains a top priority.
Running
at full capacity, 24/7, Lynca Meats comprises 28 temperature-regulated
rooms for the production of a host of processed pork products; an
abattoir that markets carcasses, boxed meat and offal; and dedicated
units that offer multi-principle cold storage warehousing and logistical
solutions to clients.
This
means that the basic utilities of electricity and heat represent some
of the biggest running costs on Lynca’s balance sheet. As Manie de Waal,
CEO of EP Solar explains, outsourcing these functions to a service
provider has made all the difference in keeping this part of the
business as economical as possible.
“Operating
a massive refrigeration set-up like this at full capacity every single
day of the year is hugely expensive in South Africa, where annual
electricity tariff increases continue to exceed inflation. Luckily,
this same production schedule makes Lynca Meats a prime candidate for
affordable renewable energy.”
Lynca
consulted with EP Solar on the issue, and the solution put forward was a
962kwp rooftop-mounted photovoltaic system. The size of the system
was limited by the rooftop space that the client had available, but it
would still be able to account for about
15% of the facility’s
energy usage. According to De Waal, generating renewable energy on site
in the form of solar power, would potentially save the operation around
R350 000 in the first year alone. “We estimate
that throughout the length of the contract, the client would save
around R16 million in electricity costs.”
“In
addition, the solution would be provided as part of a power purchase
agreement, meaning that the client did not need to invest any upfront
capital
or be burdened with the daily operation of the system.”
De
Waal notes that the system provides peak output during regular business
hours, when grid-based electricity tariffs are at their highest.
“Through
software on the inverters, solar power is always prioritised during the
day, while the site runs completely on electricity from the grid during
off-peak hours. The advantage of an operation such as this, which runs
24/7, is that it ensures that 100% of the
PV power is utilised every day of the year, strengthening the business
case. The PV system is currently in the process of being commissioned
and will soon be producing electricity for the site.”
Cutting
down on electricity spend also required Lynca to review the most
energy-intensive parts of its operation. “Of course, this was
refrigeration.
Again, outsourcing this was by far the most viable option, and EP
Refrigeration was able to offer a state-of-the-art solution,” says Dawie
Kriel, Director of EP Refrigeration.
With
the temperature requirements for the facility ranging from -25⁰C to
5⁰C, Kriel explains that Lynca Meats’ existing 20+ year-old
refrigeration
system was fast becoming inefficient. “The old system had extremely
high energy requirements, and system maintenance had become quite
challenging and expensive.”
EP
Refrigeration subsequently offered the upgrade under the EP Cooling
Sales Model on a ten-year contract. The entire system would be installed
at no capital cost to the client, and EP Refrigeration would maintain
the system and sell refrigeration as a utility to Lynca Meats, who would
reserve the right to buy the system on residual value at any point in
time.
“We
operate on a tariff structure that is similar to most other utilities.
This includes an availability charge and a maintenance fee that makes
up the set monthly cost for the service. Along with that, there is also
the variable charge for refrigeration, which is measured in
kilowatt-hours refrigeration (kWhR),” explains Kriel.
To
accurately quantify and measure refrigeration, and to bill the client
correctly, EP Refrigeration pioneered a cost-effective refrigeration
meter
to ensure accurate readings. In effect, these meters primarily measure
temperature and pressure, from which the used refrigeration measure is
calculated. This data is also made available to Lynca Meats, to be used
for operational or management decisions down
the line.
Having
started in January of 2019, work on the plant officially concluded in
the first week of April, without any operational disruptions having
been experienced by Lynca Meats over the working period. The newly
installed system is performing as predicted and has achieved a 30%
reduction in the cost of refrigeration for the client. In addition to
this, with the client no longer having to be responsible
for managing and maintaining the system under the outsourced contract,
Lynca Meats is also saving countless man-hours.
Lastly,
there was one final crucial component requiring a more elegant solution
– the boilers. With an average steam consumption of around 530tons
per month, which gets used for cooking, sterilisation, cleaning and
ablutions, Lynca’s boiler units were due for a major upgrade.
Jonathan Probert, CEO of EP Dryden Combustion – a wholly owned subsidiary of Energy Partners -
says that a new 4ton per hour coal-fired boiler fitted with EP
Steam’s proprietary control and monitoring system would do the trick.
“Additionally, a small reverse osmosis plant was installed to provide
the boiler with good quality feedwater, as the
site water source is borehole water of poor quality. We took over
operation of their two existing oil-fired boilers as well. These boilers
are only used in the case of either planned or unplanned downtime of
the coal boiler to ensure a continuous steam supply.”
Probert
explains that with EP Steam taking over this part of the operation on
an outsourced basis, Lynca was able to save another R110 000 per month.
“Other benefits include improved uptime because we now have redundancy
built into the design (standby boilers), and that the client no longer
needs to pay any attention to the steam generation operation (including
labour, maintenance and inspections).”
In
closing, De Waal says that Lynca Meats currently stands out as a
testament to what is possible when one takes a fully outsourced
approach. “This
general principle can apply to any abattoir, as well as any other
operation that runs at full capacity for most of the year. We would go
as far as to say that this is exactly what the agri and food production
sectors will need to do to maintain their profit
margins in the years to come,” De Waal concludes.
