Meeting the demands of emergent small-format supermarkets requires a new approach to — or adaption of existing — refrigeration architectures. This blog is based on a recent article that discusses available options. Read the full article here.

One of the biggest trends shaping the food retail industry is the shrinking store footprint. Instead of building large mega centers that once dominated the landscape, today’s retailers are opting to extend their brands into smaller stores, typically in densely populated areas. The small-format trend is part of a larger evolution — one that emphasizes high-quality, fresh, perishable offerings while appealing to consumer desire for more convenience.

Food retailers that are embracing these changes must also evaluate how their approaches to refrigeration architectures and controls will also need to adapt. Fortunately, there is no shortage of available options to help operators make this transition.

Scale down for “centralized” familiarity
A traditional big-box supermarket has more than 100 cases (a mix of medium- and low-temperature cases) supported by centralized refrigeration racks and controls designed to optimize large systems of this type. If you shrink these systems down for smaller formats with less merchandise, it stands to reason that you may not need as many racks. With stores shrinking from more than 100,000 to less than 20,000 square feet, they simply won’t need the same refrigeration horsepower.

In many cases, operators may still want to use centralized architectures for both medium- and low-temperature cases, but appropriately scaled down to suit the small format. Often, we’re able to design a system with one rack to manage medium- and low-temperature needs. Since it’s a much smaller centralized system to support fewer case lineups, it has much shorter refrigeration lines running out to the cases.

From a system controls standpoint, this smaller centralized architecture isn’t drastically different, so retailers can achieve relatively the same look and feel in both large and small store formats — while also providing the flexibility to scale across the full spectrum of store sizes.

Explore “distributed” efficiencies

While distributed refrigeration systems have been preferred in large supermarkets in Europe and other global regions, they are also well-suited for the small-format emergence in the U.S. Distributed architectures come in different formats and offer a cost-effective refrigeration strategy for smaller stores. Preferred distributed architectures include:

  • “Self-contained” cases (i.e., a completely integrated refrigeration system within the case); also provide spot-merchandizing flexibility
  • Modular refrigeration systems capable of supporting small lines of cases sharing similar characteristics

Distributed architectures also have a greater impact on the way controls are set up and utilized. In a distributed scenario, electronic controllers are installed at the refrigeration cases. Additional sensors are typically required to capture data, allow for better control, and support remote troubleshooting activities.

Standardize your footprint

When adding smaller-format stores to an enterprise network, it may not be in your best interest to introduce a completely new refrigeration and controls platform. For retailers with multi-site networks of large- and small-format stores, it’s especially important to select refrigeration architectures and control platforms that provide a standardized view.

When evaluating refrigeration options, look for platforms that support the evolution of internet of things (IoT) in refrigeration and facility management. These systems represent the next generation of operational efficiencies by offering cloud connectivity, predictive maintenance and advanced multi-site management software.

 

Beyond Saving: What’s Next in Supermarket Power Management?

Last fall, a gathering of food retailers, industry professionals and energy experts converged in Houston for our latest E360 Forum. This daylong event was packed with the latest news, views and best practices on hot-button industry issues: regulations, emerging technologies and more.

Matt Smith, project manager for San Diego Gas & Electric’s Emerging Technologies Group, and I explored fresh ideas on what the future holds for supermarket power management. What follows are just a few of our observations.

Future of lighting rebates dim

Utility incentive programs for food retailers, in all markets, are changing. Lighting upgrades and retrofits fueled by rebate incentives were once low-hanging fruit for commercial and industrial consumers alike. However, laborious rebate application processes have contributed to waning interest and participation — especially among food retailers. Policy and regulations have also had an impact. As CFL and LED technologies become standard, rebates are no longer seen as necessary to incentivize adoption and won’t help utilities reach their energy-savings targets. Now energy providers are looking for other more innovative and targeted ways to incentivize efficiency.

Collaboration key to more customer-centric incentives

Admittedly, supermarkets are an underserved market for utility companies. There are simply not a lot of programs designed with the distinct needs of grocery retailers in mind. However, Matt thinks this is changing.

“We’re moving toward a more vertical approach on how we run programs in the sense that we’re serving a customer segment rather than a [category] like refrigeration … That will lead to programs that are better suited for specific customer segments like supermarkets or convenience stores.”

Matt went on to say that utilities want to hear from food retailers. They welcome the opportunities to connect and collaborate — either directly or virtually. Many offer cooperative bodies, online forums and other ways to engage. In California, utilities and other energy professionals have created the Emerging Technologies Coordinating Council (www.etcc-ca.com) as way to collaborate, develop and facilitate new and emerging technologies. Other regions offer similar resources and channels.

Pay-for-performance programs offer opportunities for efficiency and innovation

Pay-for-performance programs are another relatively recent energy-efficiency trend — one that doesn’t rely on rebates or other incentive-based equipment purchases. It allows participants to identify various energy-saving measures. Payments are made over time and are based on actual energy savings measured at the meter.

The beauty of pay-for-performance programs is that they can offer an integrated, more holistic approach to energy efficiency. Savings can come from building retrofits and equipment upgrades as well as from behavioral or operational and maintenance activities. These programs also shift the responsibility for energy savings from the utilities to energy-efficiency project implementers — and can be real incubators for innovation, efficiency and new technologies. Less prescriptive and more proactive, they offer greater opportunity for collaboration and invention.

Power markets and effective demand management

Many utilities are incentivizing commercial and industrial customers to participate in demand management/demand response programs. These are developed to cut electric consumption during peak times of the day when electricity is in high demand. Effective demand management rewards customers who can conserve when the grid is taxed the most. While a proven practice in other industries and abroad, these programs are not commonly employed among food retailers in the U.S., even though the opportunities and technologies are available.

The high usage of electricity by supermarkets makes it very attractive to participate in these programs. However, reliability and flexibility in a supermarket’s HVACR and energy requirements are absolutely essential for success. Technologies like today’s smart refrigeration systems and thermal storage are ways to optimize thermal potential by shifting electricity usage at expensive times to lower-rate periods.

More grocery retailers of today are looking hard at current HVACR systems and exploring strategies and technologies to shift energy consumption without compromising food safety. We’re excited about the possibilities.

As I shared, “Demand management is becoming a really big deal using supermarkets. I use the term ‘virtual power plant’ pretty easily in this conversation. If you’ve got a flexible store and can provide thermal storage, you could actually use that store as a virtual asset for the utility. [It creates] a kind of push and pull with the power demand … All this stuff is extremely exciting, especially in this segment or business.”

Demand management programs and today’s power markets represent a real opportunity to generate revenue by using thermal capacity, transforming your energy-eating equipment into an energy asset.
