Generac Expands Innovative Line of Power Series Transfer Switches

Joseph Coupal - Monday, October 30, 2017
South Shore Generators - Generac Natural Power Series Transfer Switches

Introducing a new line of automatic transfer switches has allowed Generac Power Systems to expand its current product offering and improve the safety of operators and technicians in the field. The next wave of Power Series transfer switches, which include 100-1600-amp service entrance rated models and 2000-3000-amp non-service entrance rated contactor-based models, provide simplified mechanisms when compared to dual breaker products and promote safety with optional maintenance selector switches, which isolate control cabinets from on-site power sources.

While new service entrance-rated models feature 100 percent-rated circuit breakers with electronic trip capabilities and long/short time adjustments for instantaneous breaker coordination, non-service rated switches offer stored energy mechanisms that allow manual operation under load. Thanks to separate low- and high-voltage compartments, all models will also be able to minimize the potential for arc flash exposure during maintenance.

These additions are UL1008 and CSA rated, and feature the same controllers as other Power Series models. Equipped with the same LCD displays as existing Power Series transfer switches, these controllers enable easy programming, system diagnostics and help menu access to ensure ease-of-use for customers familiar with past controller models.

All switches feature in-phase or time delay neutrals and indicate switch operation with an easily understandable mimic diagram. A multi-tap control power transformer also allows each switch to be field converted if necessary. Other optional features include a digital multifunction power quality meter, remote annunciators, transient voltage surge suppression and Ethernet connectivity for integrating Building Management Systems.

Expanding the breadth of its automatic transfer switch options will allow Generac to efficiently support the needs of various backup power systems, including light industrial sites, emergency standby and critical power applications.

The Use of Natural Gas Generators, Is Natural Gas or Diesel More Acceptable in MA?

Joseph Coupal - Monday, October 23, 2017
South Shore Generators - Generac Natural Gas Generators

Generac Industrial Power recently attended the 2017 NFPA conference in Boston, Mass. to discuss the use of natural gas generators in emergency system applications with the authority having jurisdiction (AHJ) community.

The reliability of natural gas as fuel for emergency generator applications tends to create interesting discussions within the market. As the standard for standby power generation, NFPA 110, has plenty to say about reliability concerns and best practices relative to adequately maintaining on-site diesel. However, it provides little guidance for the acceptance of natural gas reliability. The National Electric Code (NEC) article 700.12(B)(3) states: “Prime movers shall not be solely dependent on a public utility gas system for their fuel supply - except: ‘Where acceptable to the authority having jurisdiction, the use of other than on-site fuels shall be permitted where there is a low probability of a simultaneous failure of both the off-site fuel delivery system and power from the outside electrical utility company.’”

So what is reliable enough? According to a 2013 report by Massachusetts Institute of Technology’s (MIT’s) Lincoln Laboratory, natural gas distribution systems operate at a reliability rate exceeding 99.999 percent, with the exception of seismically active areas. Incidentally, that makes the natural gas distribution system approximately one thousand times more reliable than a single-engine generator set, which is typically assumed to be 99 percent reliable. To probe these questions, Generac surveyed 110 attendees at the NFPA show with three questions:

Is natural gas acceptable in your area?

The first asked if natural gas was an acceptable fuel for emergency system applications in their jurisdiction. Sixty-four percent replied yes; another 25 percent was uncertain. This illustrated a very high acceptance rate that mirrors the explosive growth in natural gas generators documented by Frost and Sullivan – 38 percent of the total North American market revenue is now natural gas generators, which is up from 28 percent only three years prior.

Who dictates acceptance? What guidelines exist?

The second question asked who determines if natural gas is an acceptable fuel for emergency systems and whether there are guidelines for accepting or rejecting this continuous fuel source. To this question, the respondents identified AHJ & fire marshal by 36 percent, but 43 perecent were uncertain. None of the respondents provided guidance regarding guidelines for acceptance. This highlights some of the challenges that are created when the code uses subjective language and provides little guidance regarding reliability. To that end, the Centers for Medicare & Medicaid Services (CMS) created a guideline regarding the evaluation of natural gas generators for nursing homes. The reliability of a natural gas fuel source can be proven with a letter from the natural gas vendor that contains the following:

  • A statement that the fuel source is reasonably reliable
  • A description supporting the assertion that the source is reasonably reliable
  • A statement of the low likelihood of an interruption
  • A description supporting the assertion that the likelihood of interruption is low
  • A signature from technical personnel

Similar processes, which leverage a letter from the local gas utility, are often utilized by the AHJ community when natural gas reliability is perceived as questionable within the market. Another method for determining reliability may leverage the guidance given for determining electric utility reliability in fire pump applications. NFPA 20 A.9.3.2 defines reliable as not having experienced any shutdowns longer than four continuous hours in the year prior to planning. This standard does not require the utility source to be infallible; it only requires a utility source free from routine outages. Using these criteria, most natural gas systems across the United States should be deemed reliable.

What is your personal perception of natural gas?

The last question focused on each attendee’s personal perception of natural gas reliability. Fifty-five percent of the respondents felt natural gas was favorable to diesel with 38 percent uncertain. This relatively high perception of natural gas reliability is influenced by personal experiences with hurricanes Irene and Sandy, both of which destroyed the long-standing conventional wisdom that diesel fuel delivery was assured even during the most severe emergencies. Both storms caused enough damage to the petroleum supply networks, making refueling requirements a challenge. Hurricane Sandy devastated fuel terminals across the Northeast. Even if a delivery truck was able to get to a terminal, it was unlikely it would be able to obtain fuel. The available fuel and trucks within the region were often redirected by the government to hospitals and targeted emergency response facilities.

It is incorrect to conclude that diesel fuel, simply by its on-site presence, is more reliable than natural gas. A reliable fuel supply is one that is consistently available in sufficient quantity and quality to ensure reliable emergency power. It is necessary to holistically examine external factors influencing the relative reliability of natural gas and diesel.

The Boston NFPA conference allowed Generac a great opportunity to explore these topics directly with a cross section of the AHJ community. These insights help illustrate that natural gas acceptance continues to grow within markets that have an established natural gas infrastructure. In these markets, the resulting awareness and acceptance of natural gas-fueled emergency generators is quite high.

How the Internet Kept Running During The Hurricanes

Joseph Coupal - Monday, October 16, 2017
South Shore Generators in Wareham,MA

At one node of the industrial backbone that keeps the internet running, employees sheltered from the worst of Hurricane Irma in a stairwell of a seven-story building in downtown Miami. When the power had gone out, diesel generators instantly kicked in to keep the lights on and prevent the internet from going down.

In Houston, at another of these nodes, called data centers, Hurricane Harvey pushed waters so high that a live fish flopped in a loading dock, but the physical defenses held.

Yet another data center, west of Houston, was so well prepared for the storm — with backup generators, bunks and showers — that employees’ displaced family members took up residence and United States marshals used it as a headquarters until the weather passed.

“It wasn’t Noah’s ark, but it was darn close,” said Rob Morris, managing partner and co-founder of Skybox, the company that runs the center.

For all their seeming immateriality, the internet and the cloud rely on a vast industrial infrastructure consisting of data centers linked through a sprawling network of fiber optics. The facilities are stacked with servers — boxlike computers that crunch the data for everything from hospitals, law enforcement agencies and banks to news websites, email and weather reports — that cannot be without electricity and cooling for even a fraction of a second.

Yet even as millions of people lost power across Florida, and thousands of homes and businesses were flooded out in Miami and Texas, the heavy digital machinery at the heart of the internet and the cloud held firm.

Though the storm disabled some cellphone towers and local connections, the center never stopped processing and transmitting data. It lost utility power around 8:30 a.m. on Sunday, Sept. 10, but supplied its own electricity with the generators.

When the storm eased and he walked outside, Mr. Eassey said, he immediately saw the effect that Digital Realty and other data centers had by keeping the servers going. “Everyone was talking on their phones, searching on their phones, and commerce that uses the internet to do their business was up and running,” he said.

A list of Digital Realty’s top customers shows why those operations are so important: Clients include IBM, Facebook, CenturyLink, Oracle, Yahoo, Morgan Stanley, AT&T and JPMorgan Chase, among others.

Inside the centers, the drill during a natural disaster can be overwhelming. One company, EdgeConneX, lost utility power for three days at a Miami data center, two days at a center in Jacksonville, Fla., and two days at an Atlanta location. But Rich Werner, director of operations at the company, said that backup generators turned on and service was never interrupted.

“Data center operations, to me, is 362 days of boredom,” Mr. Werner said. “And then you get these hurricanes coming through, and it’s three days of pulling your hair out.”

There are no legal standards for data centers unless they house servers for clients like government agencies, which require special protections.

But a professional organization, the Seattle-based Uptime Institute, rates the facilities on four tiers of resiliency for events like storms, earthquakes and run-of-the-mill power failures — possibly one reason the internet performed creditably during the hurricanes. The institute’s engineers “go to the site and pull the plug,” said Mark Harris, senior vice president of marketing, “and to be certified, it has to keep running.”

So when a hurricane or a tornado or an ice storm happens, the entire data center has been designed to withstand these external factors.

During Harvey and Irma, those measures seemed to work, said Doug Madory, director of internet analysis at Dyn, a web performance company with servers at a Miami data center. “I’m not aware of any core internet services going down,” he said.

Practically every single large oil and gas company in the world” operates servers in its data centers — an indication of how commerce of all kind relies on the facilities.

Depending on local conditions, some centers got off easier than others. In Houston facilities run by Data Foundry, automated systems worked so well that employees pooled resources and watched the Floyd Mayweather-Conor McGregor fight on pay-per-view.

Everyone in the business says that extensive preparation is critical.

The peak of the storm passed over the weekend, and when the power went out, the center was ready with diesel generators and a 10,500-gallon diesel tank on the site.

In Houston’s so-called energy corridor, the Skybox campus stayed above water. Utility power never went down. But the site was stocked with thousands of gallons of diesel fuel, as well as food and water, emergency medical kits, showers, bunk rooms and flares.

The site, which is a “modern-day fortress,” began hosting not only employees but several of their families, whose houses were flooded. Then the building doubled as an emergency response center for the United States marshals. Roughly 50 people used or stayed on the campus at one point or another during the storm.

South Shore Generator - Kohler Pro7.5e portable generator

Expanding the company’s alternative fuels offering, KOHLER is introducing a Tri-Fuel Conversion Kit. Designed to pair with KOHLER’s new PRO9.0 portable generator, the kit enables the PRO9.0 to run on three different fuel types: gasoline, propane or natural gas. Users have the flexibility to select between the three fuel options by swapping out the fuel hose and simply turning a dial.

The tri-fuel portable generator is a great new option because it provides the convenience of three-in- one functionality. The PRO9.0 can be quickly adjusted to run on different fuels, based on fuel availability or a user’s individual preference. Propane and natural gas are sometimes selected due to the reduced emissions and run-time cost savings that those fuels can deliver.

South Shore Generator can quickly configure the new PRO9.0 portable generator with the Tri-Fuel Conversion Kit, while maintaining the product’s original warranty. Like other KOHLER portable generators, the PRO9.0 is backed by a premium three-year warranty and the company also offers a free loaner unit – through participating dealers – for any warranty repairs exceeding 24 hours.
