Standby or Backup Power Solutions For Data Centers or Mission Critical Facilities

Joseph Coupal - Monday, November 13, 2017
South Shore Generators - Generac Natural Gas Generators

The standard backup solutions include standby generators and UPS systems. IT is critical to ensure that the standby generators are not overloaded under all failure conditions. Additionally, the generator must perform properly under all failure modes harmonic distortions. The engineer must specify a generator with the appropriate level of subtransient reactance. Also, it is a good idea to specify a generator that is “mission critical” rated for a load factor of 85%.

Time-tested, tried, and proven systems: standby diesel generators with closed-transition bypass isolation switches and static double-conversion on-line UPS with batteries. Paralleling gear is necessary when capacity or redundancy requires it, but I avoid generator paralleling gear unless necessary for capacity. It has become a single point of failure on some projects.

In large mission critical facilities, a current trend among engineers is to specify medium-voltage generators because it is possible to obtain utility service at 15,000 V or higher—a significant benefit over the conventional 480- or 600-V systems. This has required larger but fewer feeders—therefore, less copper—with an associated cost savings. This is a successful, robust power strategy, but we have had to manage the increased risk of arc flash events and other medium-voltage safety practices and equipment to satisfy medium-voltage electrical commissioning and testing—often at full load.

Common Data Center Surprises

Joseph Coupal - Monday, November 06, 2017
South Shore Generators - Generac Natural Gas Generators

Appropriate technologies and best practice tips can help data center managers and consulting-specifying engineers prepare for the unexpected.

Below is a list of 10 common surprises for data center managers and tips on how to be prepared for them. The list includes information on a surprising cause of data center downtime, what data center managers and engineers might not know about that next server refresh, and the growing trend sneaking up on virtually every data center.

When you are a data center manager or consulting-specifying engineer, very few things are more unsettling than the unexpected. We hope this list helps IT and engineering professionals better anticipate these issues and prepares them with the appropriate technologies, solutions, and best practices.

Common data center surprises include the following:

  1. Those high-density predictions finally are coming true: After rapid growth early in the century, projections of double-digit rack densities have been slow to come to fruition. Average densities hovered between 6.0 and 7.4 kW per rack from 2006 to 2009, but the most recent Data Center Users’ Group (DCUG) survey predicted average rack densities will reach 12.0 kW within three years. That puts a premium on adequate UPS capacity and power distribution as well as cooling to handle the corresponding heat output.
  2. Data center managers will replace servers three times before they replace UPS or cooling systems: Server refreshes happen approximately every three years. Cooling and UPS systems are expected to last much longer—sometimes decades. That means the infrastructure that organizations invest in today must be able to support—or, more accurately, scale to support—servers that may be two, three, or even four generations removed from today’s models. Today’s data center manager must ensure that infrastructure technologies have the ability to scale to support future needs. Modular solutions can scale to meet both short- and long-term requirements. Engineers will need to consider and make the necessary adjustments and allocations regarding day-to-day servicing and maintenance of the longer lasting power and cooling equipment.
  3. Downtime is expensive: Everyone understands downtime is bad, but the actual costs associated with an unplanned outage are stunning. An outage can cost an organization an average of about $5,000 per minute. That’s $300,000 in just one hour. The same study indicates the most common causes of downtime are UPS battery failure and exceeding UPS capacity. Avoid those problems by investing in the right UPS—adequately sized to support the load—and proactively monitoring and maintaining batteries. This gives engineers an opportunity to share best practices with clients and recommend battery monitoring solutions and high-end availability architecture. They can use the cost of downtime information to support recommendations and ensure clients understand how they can implement design changes and modifications that will improve availability.
  4. Energy rebates are available for energy efficiency upgrades: Many utility providers offer energy rebates and incentives for data centers that make energy efficiency improvements. This presents an opportunity for engineers to propose high-efficiency designs and help clients receive reimbursements for upgrading legacy equipment with high-efficiency power and cooling systems. Clients may also look to engineers to assist with the often lengthy application process. Once the reimbursement has been approved, utilities will request information on actual project costs and may require follow-up measurement and verification to determine actual energy savings.
  5. Industry codes are playing a larger role in cooling strategy: In the 2010 edition of ASHRAE 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings, the SCOP (seasonal coefficient of performance) rating was expanded to include data centers. Codes such as this, which focus on energy efficiency, are becoming more numerous and impacting data center cooling strategies and technology developments. It is important that engineers keep abreast of new codes and regulations and the latest technologies that enable compliance.
  6. Monitoring is a mess: IT managers have more visibility into their data centers than ever before, but accessing and making sense of the data that comes with that visibility can be a daunting task. According to an Emerson Network Power survey of data center professionals, data center managers’ use, on average, at least four different software platforms to manage their physical infrastructure. Of those surveyed, 41% say they produce three or more reports for their supervisors every month, and 34% say it takes three hours or more to prepare those reports. The solution? Move toward a single monitoring and management platform that can consolidate that information and proactively manage the infrastructure to improve energy and operational efficiency, and even availability.
  7. The IT guy is in charge of the building’s HVAC system: The gap between IT and facilities is shrinking, and the lion’s share of the responsibility for both pieces is falling on the IT professionals. Traditionally, IT and data center managers have had to work through facilities when they needed more power or cooling to support increasing IT needs. That process is being streamlined. For engineers, it is important that they now incorporate all of these players into the design process. Gone are the days when the engineer had to work with only one or two individuals, usually from the facility side. Now it is a complex ecosystem comprised of IT, operations, facilities, and sometimes procurement.
  8. That patchwork data center needs to be a quilt: In the past, data center managers and engineers freely mixed and matched components from various vendors because those systems worked together only tangentially. However, the advent of increasingly intelligent, dynamic infrastructure technologies and monitoring and management systems has increased the amount of actionable data across the data center, delivering real-time modeling capabilities that enable significant operational efficiencies. IT and infrastructure systems still can work independently, but to truly leverage the full extent of their capabilities, integration is imperative.
  9. Data center on demand is a reality: The days of lengthy design, order and deployment delays are over. Today there are modular, integrated, rapidly deployable data center solutions for any space. Integrated, virtually plug-and-play solutions that include rack, server, and power and cooling can be installed easily in a closet or conference room. On the larger end, containerized data centers can be used to quickly establish a network or to add capacity to an existing data center.
  10. IT loads vary—a lot: Many industries see extreme peaks and valleys in their network usage. Financial institutions, for example, may see heavy use during traditional business hours and virtually nothing overnight. Holiday shopping and tax seasons also can create unusual spikes in IT activity.

Businesses depending on their IT systems during these times need to have the capacity to handle those peaks but often operate inefficiently during the valleys. A scalable infrastructure with intelligent controls can adjust to those highs and lows to ensure efficient operation.

Best Lightweight Portable Generators

Joseph Coupal - Monday, June 26, 2017
South Shore Generator - Kohler Pro7.5e portable generator

The best lightweight portable generators can give you all the power you need for good times in the great outdoors. With a complete line of lightweight portable generators from twenty pounds to sixty pounds, you are presented with convenient choice.

How You Will Use Your Portable Generator

It is extremely important to consider the weight of your portable generator with respect to how you are going to use the unit. Lightweight portable generators are ideal choices for lighting up a campsite, charging your boat battery, powering your small appliances, and for powering your tailgating appliances. As you can see, the portability of the generator matters a lot.

It will take you less energy to place your portable generator into the boot of your van while going camping. In fact, a unit of this nature can be handheld, something that is impossible with large portable generators. As far as the usage is concerned, most of the lightweight portable generators have relatively convenient wattage ratings, both for the surge as well as constant wattage.

Features to Look For

Apart from being compact and lightweight, you need to make certain that the lightweight portable generator you choose fulfills all your appliances requirements. You should look for portable generator models that provide fuel efficient operation, along with quiet power for your recreational as well as household requirements. The best lightweight portable generators you consider should pack as many features as possible into a strong, but lightweight generator design.

The portable generator you choose should be built around innovative systems, which have the capacity of delivering higher quality as well as cleaner electricity. The power produced by the portable generator you choose should be reliable. With higher quality, cleaner power, you will be able to run sensitive appliances without concerns of them getting damaged. You should also ensure that the gen-set you select has overload protection; this helps to protect the generator against unexpected overload.

The best lightweight portable generators should be integrated with optimal fuel efficiency. Choose a lightweight portable unit with a convenient fuel tank capacity that can keep the generator running for a good number of hours on a single fill. The engine should be air-cooled OHV model, with an effective horsepower and engine displacement. Units that are user-friendly are highly recommended.

Apart from the lightweight features, a good portable generator should have a centralized control panel. A centralized panel provides you with the opportunity of accessing all the generator features easily. It is also advisable to go for generators with noise reduction capabilities. Therefore, you need to engage lightweight portable generators with super-quiet mufflers, in addition to vibration isolating feet. Any portable generator with the stated features will definitely have a lower noise level, mostly ranging between fifty and seventy decibels.

Conclusion

As far as the best lightweight portable generators are concerned, you can effectively carry one of them to the campsite, boating activities, and tailgating. These portable generators are ready to provide you with clean and quiet power for any low-powered appliance. You should unquestionably buy one of these generators. Well, they might be lightweight and smaller, but be rest assured that they produce enormous electricity to power your TV set, radio, camping lights, and so on. These portable generators are significantly useful to campers and tailgates, since they do not consume space, they are compact, and they are extremely super-quiet.

Make Portable Power More Convenient with a Manual Transfer Switch Panel

Joseph Coupal - Tuesday, May 30, 2017
South Shore Generator - Kohler Manual Switch Transfer

To use a portable generator without the hassle of running extension cords, install a manual transfer switch subpanel off your main circuit panel and install a dedicated inlet to power the subpanel (installing the subpanel is complex; not a DIY project). This setup gives you the advantage of powering entire circuits in the house, not just individual appliances. The drawback is you still have to start and maintain the gas-powered generator. And unless you buy a large generator (they’re available with more than 15,000 watts), you’re still limited in what you can power.

Before calling an electrician to add the subpanel, choose what you want to power during an outage. It’s worth including a circuit that’ll let you run your TV, computer and a lamp, especially if you lose power for days at a time, so you can keep everyone entertained. Plus, these electronic devices don’t require a lot of wattage. The circuits you want powered will be moved from your main circuit panel to your subpanel, so they’ll run when you have normal power and when you lose electricity and hook up the generator.

During a power outage, run a cord from the generator to the inlet, flip a manual transfer switch on the subpanel, and all the designated circuits will have power. Choose a heavy-duty extension cord (photo above left) with twist-lock ends (generators have receptacles for these ends) that stay in place once they’re plugged into the generator and inlet. Be sure to keep the generator at least 10 ft. from the house.

Generators for Boats: What to Look For? Wareham, MA

Joseph Coupal - Monday, April 24, 2017
South Shore Generator - Kohler Marine Generator

INVERTER OR GENERATOR?

Inverters change the DC power of the boat's batteries into AC power. They're compact and quiet but limited in output by the size of your bank of batteries and by the alternator's ability to keep up with the draw. Battery capacity should be at least three times the expected need between charges. Use inverters for short-term items such as coffeemakers and microwaves. Boats without air conditioning and loads in the 1,000-to-3,500-watt range can get by with inverters. However, for greater and longer power demands you will need a generator.

INVERTER/GENERATOR SYSTEMS

Save money by combining an inverter with a generator. When demands are low, use the inverter. When demands are high-such as when using air conditioning, freezers, and dishwashers-switch to the generator. You may be able to get by with a smaller, less expensive generator.

GAS OR DIESEL?

Match the generator's fuel needs with those of your main engines so you won't need a separate tank, necessitating extra trips to the fuel dock. Diesel is more expensive than gas but also more efficient. If you're buying a gas generator, it must be spark-free to avoid explosions. Also, you'll need to install extra cabin CO alarms.

ENGINE TYPE

Two-cylinder engines tend to vibrate. Four cylinder engines need to be counter-balanced to reduce vibrations. Three- and six-cylinder engines are naturally balanced and run smoothest.

RUNNING RPM

A generator will come to its designed voltage and frequency-60Hz in the United States and Canada-at a preset speed. For most generators, this will be at either 1200, 1800, or 3600 rpm. The 1200 models are large and heavy, and rarely used on pleasure craft. The 1800-rpm models are the most common. They're inexpensive, fuel efficient, quiet, and dependable. A 3600-rpm model might provide more power in a smaller and lighter package, but its high-revving design increases noise and decreases longevity. Consider adding the manufacturer's sound enclosures to minimize sound levels with a 3600-rpm unit.

ENGINE OR HYDRAULIC DRIVE

Hydraulic-drive generators are powered by a hydraulic pump on the main engine. The engine must be running to produce electricity. They're less expensive than self-powered models but are only suited to boats with intermittent power requirements or long-range cruisers that are under power most of the time.

OUTPUT

A generator that is too small will consistently trip breakers, wear out quicker, and possibly damage your electrical equipment. Too large a generator can also operate inefficiently, resulting in carbon buildup on the cylinder heads, and leaving unburned fuel in the exhaust. Never run with a load of 25 percent or less of the generator's output. From 40 to 75 percent is ideal.

ESTIMATING LOAD

List all the wattage requirements of the appliances on your boat. Figure you need the maximum possible load (in watts) to run appliances and lights. Remember, the wattage required to start a motor (on a refrigerator, freezer, or air conditioner) can be many times (up to 10) the normal running wattage. Starting wattage will be noted on the label with running wattage. Factor in this extra load.

COOLING

Most marine generators are water-cooled and can use one of three types of systems. Raw Water: Least expensive. This system circulates raw sea water through the engine. As a result, potential corrosion and contamination problems make them a poor choice for marine use. Heat Exchanger: Most common. Cool raw water is taken from outside the hull and continually passed over a series of coils that are part of the engine's closed freshwater cooling system. Only parts exposed to the raw water are vulnerable to excessive corrosion or contamination. Keel Cooled: This completely sealed freshwater system, foregoes the seawater cooling circuit, opting instead for the closed-loop, water-jacket circuit. A pump to move the coolant through a cooling grid located on the bottom of the boat. This keel cooler must be separate from the main engine's grid.

EASY ACCESS

Look for all common maintenance points, such as the dipstick, filters, and both oil and water fills, to be on one side of the generator body so they'll be close at hand.

SOUND ENCLOSURES

These reduce engine noise, but make access for maintenance difficult. Look for ones with removable panels so you don't have to remove the whole cover to do a small job.

CONTROLS

Typically, a separate unit mounted on top, or integrated within, the generator. Digital microprocessor controls offer significant diagnostic and monitoring capabilities compared to conventional relay controls.

ELECTRONIC FUEL INJECTION

Provides easier starting, lower emissions, and steadier running compared to carbureted engines. Get it.

AUTOMATIC SHUTOFF

Make sure the unit will shut off automatically if there's low oil pressure, high coolant temperature, loss of coolant flow, or high exhaust temperature in a wet exhaust system.
