Energy IQ: Three energy and power system considerations for edge data centers

""

Technologies that require fast computing and low latency are the key drivers of edge computing, and this need for low latency necessitates edge data centers to be near the users they support. Edge data centers are the physical structures where edge computing takes place and are usually located within a few miles from where the data is generated.

Edge data centers, whether located at the base of a cell tower or on-premise at a hospital or factory, will have distinctive energy and power system considerations compared to traditional data centers. This article outlines three of the key energy and power system considerations for edge data centers. 

No. 1: Continuity of computing service will be ensured through redundancy within edge ecosystem and reliability of power systems

One of the advantages of a distributed edge data center ecosystem is that computing workloads can efficiently be moved across a network of nearby edge data centers. Consequently, users can enjoy the continuity of service even when their nearby edge data center suffers an unexpected service downtime. Therefore, edge data centers part of a robust network and able to seamlessly move computing to nearby data centers may require less redundancy in their power systems.

However, power systems’ reliability will be paramount for edge data centers that are not able to seamlessly move computing to nearby facilities without compromising latency requirements. Power systems in these applications will often feature redundant starters and batteries for increased reliability, in addition to state-of-the-art digital monitoring systems to be covered next.

No. 2: Unmanned edge data centers will require state-of-the-art monitoring systems

Many edge data centers will be unmanned, without on-premise facility technicians. Moreover, these data centers will be scattered around cities and towns, making it even more challenging to build a responsive service strategy. This is where state-of-the-art digital monitoring systems come into play. 

Power systems in these edge data centers will feature digital monitoring systems that go beyond the traditional remote monitoring and diagnostics. Often, they will include monitoring systems that provide predictive diagnostics and prognostics with a robust communication and response protocol. These state-of-the-art digital power system monitoring solutions will help operators build a more pro-active service capability.

No. 3: Power systems may be subject to stringent emission and noise requirements

As many edge data centers will be in highly populated urban and suburban areas, they will likely face stringent emission and noise requirements.

Power systems in these edge data centers could deviate from traditional systems depending upon user location. In fact, edge may be the proving ground for power system technologies beyond the historically common approach of supplementing the grid connection with back-up diesel power generators. For instance, natural gas generators with lower emission levels could be preferable in areas with robust pipelines. Solar photovoltaic (PV) and energy storage systems deliver further reduction in emissions and noise levels in areas where there is land availability and solar exposure. Finally, fuel cells could be an option for selected edge data centers. Edge data centers will likely adopt a variety of energy strategies driven by diverse deployment locations and user preferences.

As the industry’s power system needs evolve, Cummins Inc. continues to innovate. These innovations range from continuous enhancements within its diesel and gas power generator portfolio, to innovations in complementary technologies. Cummins’ recent investments in energy storage, fuel cells and advanced microgrid control technologies has boosted its capability to offer comprehensive energy solutions tailored for the data center industry’s emerging needs.

Cummins Custompaks are being used for water management as Thailand struggles with its water crisis

Water crisis

Sixty Cummins Inc. CustomPaks are in service in Thailand as part of a critical water management plan aimed at easing the country’s water crisis – a crisis that has caused enormous economic and social damage and stirred conflict among communities.

Over the past several decades, Thailand has continually faced water problems caused by severe drought. Water reserves in dams and reservoirs are insufficient while water resources are often contaminated with toxins caused by urban communities and the industrial and agricultural sectors.

Severe flooding is a threat, too, at a time when the realities of climate change are hanging over the country.

As a result, the allocation of precious water resources, which must be shared among various stakeholders including new and existing industry, large and small agriculture, and cities and villages has become a flashpoint.

Kittithanapat Engineering Co. (KTP), has been involved in the water management system since 1996, working closely with authorities such as the Royal Irrigation Department, Department of Water Resources, Bangkok Metropolitan Authority and others.

600 hp CustomPaks

To help KTP meet its often urgent requirements, Cummins DKSH (Thailand) has recently supplied 60 Australian-built CustomPaks – 45 powered by Cummins’ X15 engine rated at 600 hp, and 15 powered by the QSL9 rated at 325 hp. These fully self-contained powerpacks are emissions certified to Tier 3.

The CustomPaks are coupled to hydraulically-driven, large-volume submersible water pumps sourced by KTP from US company Moving Water Industries (MWI); KTP is the exclusive distributor in Thailand for these MWI Hydroflo pumps.

Prior to Cummins’ involvement, KTP was using another diesel engine brand but service support wasn’t up to the standard required.

Long-serving KTP engineer Kittisak Thanasoot says Cummins DKSH’s reputation for technical and aftersales support along with the reliability of the Cummins product were a key reason behind KTP’s decision to specify the CustomPaks for the Royal Irrigation Department.

The ability of Cummins DKSH to respond to short delivery times was also important.

“Supplying large quantities of high horsepower diesel engines for emergency situations such as flash flooding can be a challenge for KTP,” says Kittisak Thanasoot.

“Responding to the needs of the government agencies to manage such problems in a timely manner and with least impact on communities, KTP has found the answer in our partnership with Cummins DKSH.”

Power, pride and passion

The switch back to Cummins power has been beneficial for iconic New Zealand company Uhlenberg Haulage. It's all about whole-of-life costs.

Uhlenberg Haulage is closing in on 60 years in business, having been founded in 1966 by Mike and Carol Uhlenberg.

Based in Eltham, Taranaki, in New Zealand’s North Island, the operation is today owned and operated by their sons Chris, Daryl and Tony Uhlenberg.

Describing the Uhlenbergs as “old school family truckies”, Daryl talks about the company’s time-honored journey with a definite tone of pride, especially the work of his parents in laying the foundations for what is today an iconic fleet in its own right.

Cummins Inc. made its debut in the Uhlenberg fleet in 1971 with an NH250 powering a second-hand Kenworth K923 used in logging. A second Kenworth, a new W924 with a Cummins NTC335, followed soon after hauling an LPG tanker.

The Uhlenberg operation today comprises 40 prime movers and a variety of trailing gear to cater for the myriad of a jobs the fleet is involved in.

A number of Peterbilts feature in the fleet although Kenworth is now the brand of choice with six new units to be delivered over the next 12 months to cater for business growth.

Cummins’ X15 Euro 5 engine rated at 550 or 600 hp is the preferred power specification, with 18 red engines currently in the fleet.

Whole-of-life support

“The switch to Cummins has been a very good experience for us. We have nothing but praise for the Cummins organization,” says Daryl.

“The whole-of-life picture is the key thing for us and we’ve got that nailed with the support we get from Cummins – parts availability, scheduled maintenance, life expectancy and in-frame rebuilds.

“So the red engines turn up, we run them to life, which is 900,000 to 1.2 million kilometers, and then Cummins does an in-frame overhaul in a timely manner. If there’s an issue, parts and support are close by.

“The support we get from Cummins Palmerston North is fantastic, second to none.”

Daryl recently looked under a Kenworth that was in the workshop for a service and was surprised to see no oil leaking from the one-million-kilometer X15. “I remember when I was a fitter we had to wear a raincoat when working under a truck,” he jokes.

Fuel agnostic

Acknowledging that the push to decarbonize is now “very real”, Daryl likes the idea of Cummins’ fuel agnostic concept where one base internal combustion engine, optimized to run on diesel, can also be customized to run on ultra-low and zero-carbon fuels like renewable natural gas and hydrogen.

“My father was a pioneer of linehaul trucking in New Zealand and he always embraced new technology. He was never scared of it,” he says.

“I tend to be a little more cautious but I can see where a 500 hp natural gas or hydrogen engine would work for us in short haul applications,” he admits. “We’re certainly willing to look closely at these alternative fuel technologies when suitable infrastructure is in place.”
