Teaming up to reduce emissions

We're excited to be part of a collaborative groundbreaking project to provide information which ultimately empowers energy consumers in their daily decision-making about environmental stewardship.  Get the HERO (Home Emissions Read-Out) app HERE.

As Commonwealth's Steve Miller recently put it,“If we are successful, one outcome might be a service which (people) can employ with their appliances. To choose the time of day or place where using their appliance will cause more or less emissions.”

Shining the light on outage prevention

Today marks the infamous 10th anniversary of the August 14, 2003 blackout of the eastern United States.  The massive outage, or megablackout, determined to be the result of a tree branch in Ohio initially taking out a 345kV line, compounded by cascading failure, affected over 50 million people with an economic fallout estimated at ten billion dollars. 

Over the past decade, a great deal of effort has gone into reducing the chances of a similar widespread outage occurring in the future.  Areas of success include the creation and strengthening of standards associated with the planning and operation of power systems, and the application of new technologies, particularly Phasor Measurement Units (PMU) -- a technology driven by the same GPS technology driving the universal mapping functions in our phones and other applications -- to situational awareness. 

Despite these advances, as more recent incidents demonstrate, more work remains to be done.  Fundamental components, such as transmission lines and transformers that make up the grid, need to be updated and added to meet current needs and the desire to support new generation sources including wind, solar and natural gas fired plants.  When it comes to the potential for cascading outages of the grid, techniques for consistent analyzing these events prior to their occurrence and identifying cost effective remedies are still in their infancy.

Commonwealth Associates is an active participant in planning, identifying, and implementing such solutions and we always welcome opportunities to discuss techniques and collaborate in creating solutions.  For information about our Transmission Grid Analytics - Cascade Analysis (TM) software that helps to prevent future blackouts, click here.  In a nutshell, it provides:
  • A verifiable and complete list of “breaker-to-breaker” contingencies
  • Identification of ALL contingencies that cause violations and a direct or indirect assessment of all double (Category B and C) contingency combinations
  • Analytical methodology to supplement your engineer’s experience and judgment
  • Objective, repeatable, and reasonable classification of contingencies that cause A/R violations into those that will not cause outages beyond a predetermined area and those that cannot be eliminated as potential causes for widespread outages
  • Priority list of trouble facilities that identifies and suggests root causes for contingencies that may initiate widespread outages
  • Independent evaluation of your system suitable for use as compliance documentation that management can include in their "due diligence" reporting
  • Custom solutions

An ounce of prevention is worth a pound of cure.

25 Years...and Counting!

This July, Commonwealth celebrated 25 years of being an employee-owned engineering firm providing world-class consulting expertise to the electric power industry and our utility, municipal, institutional, and industrial clients.  You can read more about this particularly meaningful milestone on p. 28 (p. 30 of the .pdf) of Jackson Magazine's August issue

The festivities included monthly fun activities, the official unveiling of new glass panels in our hallway of history; a Friday evening gala at the newly renovated Robert Snyder Hall in Jackson College's impressive Potter Center, where we recognized our founding shareholders and employees; and a spectacular day full of food, frolicking, and fun at our employee family picnic on the grounds of our headquarters in Jackson, Michigan. 

We feel truly honored to work with such accomplished colleagues, many of whom serve on the committees setting tomorrow's industry standards, and even more honored to be given the trust and loyalty of our outstanding clients -- among them major utilities, industrial leaders, and some of the world's most prestigious educational and healthcare institutions. 

Here is a look back at some of the best memories from this past week...we hope you enjoy them!

On Thursday, President Dennis DeCosta proudly revealed
 two new commemorative panels representing the past 25 years.

Friday evening's gala attendees enjoyed the culinary delights of
Continental Services before the program.

Guests raved about the humorous delivery of keynote speaker, author,
and former professional comedian, Garrison Wynn.
 Saturday's family picnic included: two bands, one dessert contest, a pinewood
derby championship, inflatables for kids, and the Great Anniversary Giveaway.
25 years meant 25 lucky employees took home 25 very cool prizes.

The other winner was the fight against cancer, as President DeCosta
and the VPs took to the dunk tank to raise money for Relay for Life.

Utilities and system protection

Protective relaying work directly impacts system reliability.  In fact, you could say that it's the insurance policy for protecting the assets of a utility.  That’s why it’s vitally important that the consultant a utilities hires possesses the necessary expertise and judgment to make the right call, and can easily adopt the preferred standards and protection practices used at that utility.  Protective relaying is not something learned in a standard electrical engineering curriculum.  It takes years of practice to become competent. 
Charles Mason aptly described protective relaying as both an art and science.  That’s because there is not a singular, scientifically-proven “best approach” to setting relays.  In fact, there occasionally are circumstances in which perfect coordination and protection simply cannot be achieved and the engineer is required to make a judgment call.  (Fortunately for our clients, Commonwealth's roots in the industry date back to 1888 and we have engineers with over 40 years in the business, so we bring a wealth of knowledge to client projects and have a proven track record of making the right call.) 
Modern digital relays are complex.  Each client will have unique features used, philosophy, settings criteria, and relay set up.  This “tribal knowledge,” developed over the years, may not even be known to all internal engineers.  We are helping clients to capture and document this knowledge, and providing a more rigorous, standardized format for presenting study results.  We also help translate this knowledge into standards that enable consistent relay setting by utility employees or consultants.
There are two major protection software programs in the electric utility transmission system arena – CAPE and ASPEN OneLinerTM.  With nearly a 2-to-1 utility market share, ASPEN is considered quite user-friendly. CAPE is more robust in modeling capability and running system simulations, but requires a steep learning curve and is more difficult to learn compared with ASPEN.  Commonwealth is one of a very few consultants highly experienced with both.  
Here are the Top 10 reasons to connect with Commonwealth for system protection services:
1)     We can be a seamless extension of your staff, following your utility’s philosophy and settings criteria.

2)     You get the benefit of our extensive experience with CAPE & ASPEN.

3)     You can trust us to review your settings or utility practices for NERC compliance.

4)     We can perform your system wide upgrades, including design work, updating protection standards, and relay studies and analysis to provide the relay settings.

5)     You can address the increasingly important arc flash issues by using the automated process we developed in CAPE to efficiently perform calculations in the utility environment.

6)     You can tap into our experience with analyzing event files from digital relays for troubleshooting or independent review of relay settings to diagnose misoperations.

7)     We can provide databases and data management to build combined short circuit models using data from both CAPE and ASPEN users.

8)     We have extensive field experience with commissioning and testing of new relaying systems.

9)     We can provide protection studies, coordination, arc flash, and troubleshooting for power plant electrical systems.

10)  We can help you with overflow work or get you through a period of new staff development.

Valentine Sparks

Today is Valentine's Day -- a day to celebrate all of the powerful and heart-warming forms of love displayed on this planet by mankind.  A cute article on the various celebrations around the globe can be found here

Today, paper hearts with beginner's penmanship touch the hearts of mothers and fathers the world over,

men (and women) with sweaty palms make promises of forever with that certain someone they can't imagine life without,

and life-long couples reflect back upon the deep abiding friendship that kept the romance alive during years of sacrifice and struggle...couples like this one.

We demonstrate our affection in a myriad of ways, from handmade cards to chocolates and flowers, but sometimes"sparks" on Valentine's Day are not always a good thing and the gifts we give can actually cause harm.  Learn more here:
