Case Study: USCS Safely Cuts GHG Emissions While Reducing Electrical Costs

January 19, 2023 Blog Articles, Case Studies, Cold Storage

Situation:
United States Cold Storage (USCS) is one of the top refrigerated warehousing and related logistics services companies operating throughout North America.  Their Tulare South facility is a 116,482 square foot frozen food warehouse located in the agriculturally focused Inland Empire of Southern California.  The state of California has committed to reaching a goal of 100% renewable and zero-carbon electricity by 2045, and USCS is just as committed to reducing their energy usage. To help California meet its energy demand reduction goals, USCS set out to focus on energy efficiency and better temperature control in their energy-intensive warehouses.

Challenge:
Operations managers at USCS face daily energy use challenges.  To help alleviate these issues, USCS chose their Tulare South location to explore options with energy-saving technologies.  The goals were to safely meet California’s energy demand reduction initiatives by lowering demand and greenhouse gas (GHG) emissions while also addressing energy-use concerns, decreasing costs, and increasing sustainability and resiliency.

Solution:
USCS adopted Thermal Energy Storage (TES) technology to reduce their carbon footprint and lower their energy costs.  Viking Cold Solutions installed energy meters, sensors, and controls throughout Tulare South’s temperature-controlled warehouse to monitor its operations and performance.  Viking Cold then installed energy storage modules containing environmentally friendly Phase Change Material (PCM) which, when combined with cloud-based optimization algorithms, allowed Tulare South to control when and how it uses and procures energy.  The facility’s digitization, energy storage, and cloud-based optimization allows Viking Cold to continuously assess and improve the performance of USCS’s frozen food warehouse.

Outcome:
By utilizing Viking Cold’s TES technology and optimization services, USCS lowered Tulare South’s peak period demand by more than 30% and refrigeration energy consumption by 25%, resulting in an annual carbon footprint reduction of over 350 tons at this facility.  The frozen food warehouse not only increased energy efficiency but also increased temperature stability in the freezer by over 40%, better protecting the food.

Operators of cold storage facilities, businesses with refrigeration loads, and utilities that need to control peak demands on the electrical grid all stand to gain significantly from Thermal Energy Storage.  USCS Tulare South is a prime example of how TES technology effectively lowers energy demand and consumption while improving temperature stability in cold storage facilities.  As a result, operational costs are reduced, product is protected, and environmental effects are minimized.

Isla Frio Partners with Viking Cold for Hurricane Resiliency

September 23, 2022 Blog Articles, Cold Storage

Isla Frio’s cold storage facility, in Cidra on the island of Puerto Rico, was well prepared with a back-up generator and fully charged Thermal Energy Storage (TES) when Hurricane Fiona made landfall on Sunday, September 18th.  The island was overwhelmed by historic amounts of rainfall, ranging from 6 to 20 inches, with some areas receiving over 3 feet of rain from the storm.  As the days progressed, Hurricane Fiona strengthened and left the entire island without power.  Fortunately, the resilient combination of TES and back up generation allowed Isla Frio to maintain their required safe temperatures throughout the storm – and for days longer than other facilities – by running the generator only during the day and turning it off at night to save diesel. In fact, diesel consumption was reduced by over 50% and extended the time the generator could run from 6 days to over 12 days.

Another Successful, Sustainable Thermal Energy Storage Installation in Mexico

October 8, 2021 All News, Blog Articles, Case Studies, Cold Storage, Energy Storage

Viking Cold has successfully installed another Thermal Energy Storage (TES) and refrigeration optimization system inside a third-party logistics frozen food warehouse in Mexico. Our client, Frigoríficos ARCOSA, is a leading cold storage provider with distribution centers across Mexico and has over three decades of experience providing temperature-controlled solutions and support services to their food & beverage and retail clients. They are also proud members of the Global Cold Chain Alliance (GCCA).

Operating energy-intensive refrigerated facilities in Mexico presents many challenges. Not only do operators like ARCOSA have to deal with the expected business and logistical challenges of cold storage, but the energy market in Mexico has variability which creates difficulties for operations budgets and profitability. After payroll, energy related expenses are typically the second highest cost for cold storage facilities, and refrigeration can be up to 90% of their energy costs. Without technologies and strategies that add energy flexibility, variable energy prices can negatively impact the bottom line.

In Mexico, like many other places around the globe, energy prices vary based on time-of-use with consumption and demand charges significantly higher during peak periods and intermediate peak periods (sometimes referred to as partial peak periods). Because cold storage warehouses must maintain temperatures to protect food quality, technologies that safely reduce refrigeration energy consumption and demand during Mexico’s high-priced periods without loss of temperature control are critical to cold storage profitability.

With these needs in mind, ARCOSA approached Viking Cold to see if refrigeration optimization and TES technology with Phase Change Material (PCM) could provide the energy flexibility needed to reduce energy costs and GHG emissions in their refrigerated warehouses in Mexico. Viking Cold first evaluated their 64,000 square foot freezer in Juquila.

At the time of evaluation and installation, this plant experienced intermediate peak prices up to 17 hours per day and peak prices up to four hours per day with some seasonal variations. The operating strategy had three goals:

  1. Minimize energy demand (kW) and reduce energy consumption (kWh) during each of the seasonal peak periods and intermediate periods
  2. Maintain temperature protocols
  3. Not increase energy use during any period

An interface between existing refrigeration controls and Viking Cold’s refrigeration optimization software was implemented, additional sensors were added, and TES modules containing PCM specifically engineered to the warehouse’s temperature requirements were easily integrated into the existing warehouse infrastructure.

Results have exceeded expectations, since installation of the TES and refrigeration optimization solutions:

  • Demand reductions over 380 kW during all peak periods
  • Annual weather-normalized consumption reduction of over 400,000 kWh – the equivalent of 280 metric tons of GHG emissions
  • Temperatures held within requirements
  • Approximately $120,000 (MEX$2,400,000) of annual savings at current energy prices

ARCOSA owner and President Gabriel Guzman noted, “ARCOSA’s partnership with Viking Cold has begun with positive results for both cost reductions and sustainability improvements that we hope to replicate in our other facilities.”

The flexibility Viking Cold provided to manage when and how their refrigeration system uses electricity has provided ARCOSA with confidence that when energy market changes do occur, they have technology-enabled flexibility that reduces energy risks and improves the sustainability of their cold chain operations.

Refrigeration Engineers Presentation – Efficient, Flexible, Sustainable Refrigeration with Thermal Energy Storage

June 23, 2021 Blog Articles, Cold Storage, Cold Storage Construction, Food Processing, Supermarket, Webinars & Podcasts

Refrigeration engineers often receive a lot of valuable training and education through their professional organizations. Viking Cold’s Global Director Brad North, P.E., CEM presents some of the key benefits of Thermal Energy Storage (TES) using Phase Change Material (PCM) in refrigeration applications to a national HVAC and refrigeration engineering association. In this 21-minute video presentation to engineers in the HVACR industry, refrigeration benefits such as reducing energy use, improving sustainability, minimizing temperature stratification, extending temperature resiliency, and improving interconnectivity with power from the electrical grid are covered.

Brad begins his presentation with relevant cold chain statistics about facilities where refrigeration optimization with intelligent Thermal Energy Storage is being achieved by leveraging PCM. He also explains some of the unique thermodynamic properties of PCM that allow TES systems to achieve positive refrigeration energy and temperature management results. He then covers how the PCM is configured and easily installed into various cold storage refrigerated facilities without additional space requirements or the loss of valuable storage area.

Also covered in the presentation is a brief evolutionary history of the refrigeration practice known as flywheeling – subcooling the food and surrounding room to then minimize refrigeration during periods with high energy costs. Brad discusses factors that influenced the start of flywheeling, are transforming flywheeling practices with new technologies, as well as how PCM safely extends the length of flywheeling periods while reducing the risk to food quality and shelf life. He also shares how PCM is able to slow temperature increases in a room without active refrigeration and shows case study data illustrating a reduced rate-of-rise and improved temperature stability.

Inside cold storage facilities temperature stratification throughout the room generally occurs. Brad shows some examples of how properly installed PCM combined with intelligence reduces the extent of temperature stratification and creates a more uniform temperature across the vertical space of these refrigerated rooms.  With the introduction of PCM a new “stratification floor” is created that consolidates more of the heat near the ceiling in the airflow of the evaporators for improved temperatures around the food and for easy removal of the heat by the refrigeration system.

Thermal Energy Storage is often considered a way to simply shift when energy is consumed by refrigeration systems. Brad explains many of the factors that allow Viking Cold’s TES technology to not only shift the timing of refrigeration but also to safely reduce the total kWh energy consumption (energy efficiency) of the refrigeration systems. Hear about the factors that enable this such as reducing the horsepower per ton ratio, the ability to run refrigeration systems at maximum designed efficiency or “fully loaded”, the consolidation of up to 85% of the heat infiltration near the top of the room, the PCM’s higher heat capacity and heat transfer rates, and the fact that TES systems do not have mechanical components that cannibalize the energy savings with parasitic losses.

Also discussed in this refrigeration engineer’s presentation are additional attributes of TES that provide energy flexibility and the ability to safely and easily participate in multiple utility and grid operator programs. Many of these programs reduce costs, some provide financial incentives for technology upgrades, and some programs can generate revenue streams for operators of refrigerated facilities. The added refrigeration flexibility from TES enables participation in programs such as demand response, permanent load shed, targeted load shed, peak shaving, responding to market index pricing signals, renewables plus storage, and capacity programs.

Temperature resiliency inside the refrigerated cold chain is paramount to maintaining food quality and shelf life while minimizing food loss. Brad also explains how PCM adds resiliency to cold storage rooms. Common scenarios that disrupt cold storage operations and create a need for temperature resiliency are becoming more common and include mechanical breakdown of refrigeration system components and loss of power from ice storms, hurricanes, wildfires, utility-initiated de-energization, and more. Refrigerated facilities that have TES installed have up to three times longer temperature protection during any of these situations that may cause the loss of refrigeration.

Whether you are a facilities or business leader, refrigeration engineer, cold storage operator, or somewhere in the temperature-controlled cold chain, there is something in this short professional association presentation for you. Quickly learn about mitigating risk, cutting costs, improving sustainability, stabilizing temperatures, and more.
