Putnam Sees Backup Power Systems As Wise Investment

When you are responsible for 172 institutional clients and more than 7 million shareholders and retirement-plan participants, you can't afford to blink. With more than 3500 employees and six computerized service centers in Massachusetts, London, and Tokyo, Putnam Investments has made a considerable investment in its own infrastructure -- emergency/backup power systems for all its facilities to assure continuity of service.

Growth Highlights Need for New Power Control System

Putnam, one of the world's largest money-management companies, offers mutual funds, retirement plans, college savings plans, insurance products, and institutional portfolios.

As the company grew in the late 1980s and early 1990s, Putnam learned about the differences in backup power systems firsthand. Chronically malfunctioning switchgear installed in 1986 at the company's first data center led management to reconsider its choice of equipment when planning the emergency/backup system for its headquarters in Boston. Installed in 1990, this new system included a single 800 kW generator and three open-transition automatic transfer switches manufactured by Russelectric Inc. in nearby Hingham, Massachusetts.

Russelectric designs, builds, commissions, and services switchgear and power control systems for hospitals, data centers, ISPs, airports, and other critical facilities. Systems can provide sophisticated control functions such as emergency/standby power using either open-transition transfer or live-source, closed-transition transfer; cogeneration; prime power; peak shaving; load curtailment; uninterruptible power; and utility paralleling.

Field Service in a Tuxedo

Russelectric also supports its customers with 7 x 24 field service. Barry Mosher, Project Engineering Manager for Putnam, had heard about this, but in 1991 when one of his transfer switches developed a problem, Russelectric's response made him a true believer.

"I had to shut the building down that weekend," he recalls. "If I couldn't fix the switch, we'd be out of business. I called the [Russelectric] toll-free field service number and was told the engineer in charge would be paged. He called back a few minutes later from his daughter's wedding! He understood the jam I was in and said he would be there in about half an hour. He was still in his tuxedo when he showed up. He quickly fixed the switch and checked the other switches. I was so impressed! And I never even got a bill. That day I learned firsthand that if there is ever a problem, Russelectric will fix it and fix it right."

The Power to Safeguard Financial Data

With the growth of the financial industry in the 1990s came the realization that a power outage could hurt business badly. Putnam employees field large volumes of telephone calls and e-mails from shareholders, financial advisors, and banks. Thousands of checks, statements, and other documents have to be processed and mailed on schedule. In addition to concerns about inconvenienced customers and reduced employee productivity loomed the possible loss of electronic data.

To keep up with its rapid growth, Putnam opened new facilities in three Boston suburbs between 1994 and 2000. Each has a 3000 kW backup power system that includes three generators and Russelectric closed-transition paralleling switchgear. The backup power system at Putnam's headquarters was upgraded to 1500 kW and supplemented with a web-based monitoring system that captures data (even from the London and Tokyo facilities) for analysis.

The Russelectric power control systems in all four Putnam facilities have redundant programmable logic controllers (PLCs), which coordinate the systems and can switch a facility off the grid to generator power whenever there is a problem. The controls constantly monitor the utility feed.

Choosing the Best Supplier

"Before we renovated each new building, we conducted a fresh scoping process," Mosher explains. "We weeded out the average vendors; we wanted the highest quality we could get. We looked at competitors' services, equipment, capabilities, and failure rates, and every time we went through this evaluation process, Russelectric emerged as the leader -- the best value for the dollar."

Blink and You Lose

In the event of an unforeseen power loss at any of the three suburban facilities, Russelectric closed-transition switchgear will automatically start the generators, parallel their outputs, and pick up loads in order of priority. While this entire process takes only about 20 seconds, that is still long enough for computers to "crash." With so much at stake, Putnam also invested in uninterruptible power supply (UPS) systems to prevent even the slightest power blink.

Because data centers need absolutely pure power, Putnam is taking no chances. The suburban power lines that feed these centers are strung between poles and are subject to damage from storms and motor vehicle accidents. To smooth out any irregularities or anomalies in the power coming into its three suburban facilities, Putnam runs the utility feeds through its UPS systems. This conditions the utility power and eliminates the damaging effects of harmonic distortion and brownouts.

Hunkering Down for Storms

As with the company's disciplined scoping process, Putnam's care is evident in its precautionary pre-storm transfer protocols. Although the reliability of the utility feed to Putnam's Franklin facility has since improved, from 1994 to 1999 it failed an average of 14 times per year, with outages averaging 2-3 hours each. So today, whenever a thunderstorm, blizzard, or ice storm is predicted for the suburbs (4-5 times a year), maintenance personnel use the Russelectric equipment to parallel the utility feed and the emergency generators and to transfer to emergency power before the storm hits. Each system has enough fuel to run for 10-12 days if necessary.

Routine Testing Goes Unnoticed

Because the closed-transition system design transfers each facility's loads seamlessly from utility feed to backup generators, Putnam can test the systems on a regular basis without the slightest impact on operations. In addition to the pre-storm transfers, Putnam exercises each of its suburban systems twice a month, during a workday, for four hours. Every quarter they test them for eight hours. Neither customers nor employees ever notice these tests.

Power Control People You Can Rely On

Under contract, Russelectric takes care of routine maintenance on the Putnam facilities three times a year and trains Putnam employees in the use of the equipment.

"Russelectric's training is conducted by seasoned professionals," says Mosher. "But who would expect anything less? When you tour their plant, you see that every employee takes pride in the Russelectric name. The customer is #1, and that comes across in their R&D, their service, and their overall attitude."
