Cummins Power Generation delivers critical protection power for Digital RealtyErskine Park is the first data center in Australia owned and operated by Digital Realty, the world’s largest data center provider and wholesaler. Digital Realty currently operates more than 110 data centers in 32 markets around the world, including a second Australia-based data center in Melbourne. Through the company’s ‘Turn-Key Flex’ technology, customers are able to lease fully-equipped electrical and mechanical data centers that are move-in-ready.

A data center’s massed racks of servers draw significant power and also generate a lot of heat, placing considerable demand on power supply and air conditioning systems. Emergency standby power is thus critical to ensure integrity and functionality of the computer environment.

The Cummins Power Generation team in Sydney has worked closely to meet Digital Realty’s requirements for consistency and a seamless process of supply, installation and commissioning from its suppliers.

Case HistoryEthiopia

Where:Ethiopia, East Africa

What:Products ranging from the 11 kVA C11D5T to the 1675 kVA C1675D5A

Purpose:To support Ethiopia Telecom, to expand their telecom network

Primary Choice Factors:Cummins has a strong global relationship with Huawei, the world’s largest telecom equipment manufacturer

Cummins offers a range of ratings and solutions for Telecom Towers and data centres

Standby Power

The number of generator sets supplied by Cummins Power Generation to Ethiopia Telecom Huawei, has passed the 850 mark. Supplied through Huawei of China, the generator sets are powering a multi-million dollar network that serves a diverse range of rural and urban areas, including sites where the towers must be kept operating in diffi cult and remote terrain. Products ranging from the robust 11 kVA C11D5T to the dynamic 1675 kVA C1675D5A generator have been utilized to provide standby power to a multitude of facilities within the telecom network, ensuring dependable connectivity throughout the country and thus anchoring Cummins ever-growing presence and reputation within emerging African markets.

According to Cummins Power Generation’s Director of Vertical Segments Eric Flechet, Cummins became involved in the project thanks to its strong global relationship with Huawei, the world’s largest telecom equipment manufacturer. This is the fi rst project of this magnitude the two companies have undertaken in Africa.

Complete power system accountabilityAfter evaluating various solutions in the market, Digital Realty selected Cummins Power Generation due to its leadership and well-established track record in supplying high-performance and reliable power systems. As a global manufacturer that develops, designs and manufactures the main components of the generator set, including the engine, alternator and control systems, Cummins Power Generation is able to provide a complete power system that conforms to the industry’s highest standards of design consistency, manufacturing process control and field reliability.

This data center is Tier 3 certified, as defined by the Uptime Institute, ensuring that maintenance can be performed on any part of the mechanical or electrical plant in the facility without impacting the computer equipment. Tier 3 certification requires the generator power to be regarded as prime power for the data center. Generator sets must therefore be rated for continuous operation and are part of the N+1 redundancy at the data center.

Cummins diesel generator sets work in conjunction with an Uninterruptible Power Supply (UPS) system of batteries. In the event of a mains failure, the UPS system maintains power supply until the generator sets come online and take over within 10 seconds. A total of 80,000 liters of underground diesel storage capacity in the Erskine Park facility guarantees the roof-mounted generator sets can run a minimum of 24 hours at full load.

To meet Digital Realty’s requirements, Cummins Power Generation delivered six roof-mounted C2250D5 diesel generator sets powered by QSK60G4 engines, together with custom-built acoustic enclosures and fuel systems to provide 9.6 MW of reliable prime power.

Strict criteria were set for the pre-commissioning and commissioning of the generators, including an eight-hour load test on each generator set, as well as full integratedsystem testing at the completion of commissioning to prove the operation of the generator system.

Consistency and seamless solutions integrationDespite a tight delivery timeframe, Cummins Power Generation’s experience in providing high-performance power systems for data centers, in addition to its outstanding service and support, ensured that the project was completed on time and on budget.

“Cummins Power Generation is a global supplier to Digital Realty because of its proven track record in providing critical protection solutions to the data center market,” said David Van Brussel, Cummins Project Manager, South Pacific. “In Australia,our ability to work to a very tight time schedule and ensure ongoing product support was the other key factor behind our partnering with Digital Realty.”

“Digital Realty wants consistency and a seamless process of supply, installation and commissioning from its suppliers and Cummins Power Generation has provided that for us,” said Denis Larkan, Engineering Design Manager – Australia, Digital Realty Trust. “We are extremely satisfied with the partnership between Cummins Power Generation and Digital Realty, and look forward to working closely in the long run.”

Cummins installed the gensets along with the acoustic enclosure and fuel system.

The majority of units commissioned are the smaller yet effi cient and

reliable generators ranging from the C11D5T to C66D5 providing

11kVA to 66kVA standby power. Driven by a rugged Cummins

4-cycle medium-duty engine, these units deliver reliable power,

low emissions and fast response to load changes. The control

system, PowerStart 500, provides a simple user interface to

monitor and control the unit, with manual and remote start/stop

control, shutdown fault indication and a multitude of protective

functions. These features, along with the comprehensive warranty

and worldwide distributor backing, ensures long-term reliability of

the product, affi rming the world-class reputation of Cummins.

One of the largest of the units supplied, the C1675D5A, is driven

by a 50 L Cummins heavy-duty 4-cycle industrial diesel engine,

providing optimum performance, reliability, and versatility whilst

delivering low emissions. The unit utilizes the PowerCommand 3.3

(PCC3.3) controller, designed to integrate all control functions into

a single system providing enhanced reliability and performance

compared to any other conventional generator control systems.

The PCC3.3 is amongst the most advanced controllers, offering

an unrivalled range of features including multiple language support,

alternator overcurrent protection, extended paralleling, isochronous

load share, real time clock for fault and event time stamping, and

a Modbus® interface for interconnection to customer equipment,

amongst many others. Cummins control systems are designed and

tested to meet the harsh environmental standards the generators

are expected to operate within, further cementing customer

confi dence in the ability of the product to excel to most conditions.

Ethiopia’s unstable national grid has meant an increased demand

for diesel generators. Low kVA Segment Leader for Cummins

Africa Nakul Virat comments: “The power grid in Ethiopia is prone

to severe fl uctuations and power availability is poor. As a result, we

are also currently involved in a number of projects in the healthcare

and the banking sectors.”

With the Ethiopian government’s ongoing investment in

infrastructure upgrades, Flechet believes there is further potential

for growth in the country. “We have improved our on-ground

capability by using local distributor channels in the region,” he

says. “By doing this, we have improved our customer experience and

become more aggressive in growing our market share. It is still early

days, but the long-term outlook is positive.”

Ethiopia is sub-Saharan Africa’s fi fth biggest economy, has its second

largest population, and is the largest landlocked country in the entire

continent. Among Africa’s emerging economies Ethiopia has become a

focal point for foreign investors seeking investment opportunities, and

visiting delegations are a regular event.
