Charging My Iwatch

July 27, 2015
TVs, ACs, as well as most other equipment nowadays are more efficient than they were years ago, and they continue to get more efficient.

TVs, ACs, as well as most other equipment nowadays are more efficient than they were years ago, and they continue to get more efficient. There are more solar connected to the grid now than ever, batteries are spreading as well, yet in certain areas the load continues to grow. We are mainly concerned with summer months because of the increased load as a result of the wide use of ACs; however the “mini-load” is on the rise as well.

By “mini-load”, I am referring to new gadgets that did not exist before, and do not consume a lot of electricity. Let’s address a few of them:

The Apple watch

Even though I ordered mine a few hours after the watches were made available online, yet I had to wait six weeks, since they were sold out almost instantly. I charge my watch once a day for few hours when I return home at night, which most likely is coincident with the time the substation that feeds my house peaks as well.

Bluetooth headphones

Everyone wear headphones; the difference is that we are now using fancy Bluetooth headphones that also get charged every night or so.

Adding on top of that charging your cell phones (most of us now have more than one cell phone), tablets (iPads, etc.: both of my daughters do not eat unless they are watching their Ipads, as a result both iPads get charged at night; also coincident with the substation peak) and laptops (similar to cell phones, we all have at least two laptops that we are charging overnight). So basically every night (coincident with the substation peak) including summer peak days, we charge multiple gadgets that were never part of the grid few years ago; also, since the prices are dropping, we are owing a lot more, two cell phones, two laptops, Ipads, smart watches, etc. not including our work gadgets that we also charge.

The reason we did not see a huge increase in load as a result of the above gadgets is that they are efficient; having said that when you multiply the above gadgets by the number of people in the utility’s territory, the loads will start creeping up. The smart glasses were not successful so far; however, future models may attract people, which will result in more load as well.

Mr. Mousa is an Adjunct Professor at New Jersey Institute of Technology (NJIT) teaching advanced topics graduate electrical engineering courses.

Mr. Mousa serves on the New Jersey Association of Energy Engineers board as a board member.

Mr. Mousa is currently the Principal Engineer at PSE&G in the Electric Delivery Planning section, where he is responsible for managing power system generation, transmission and distribution simulation studies, developing the short/ long range substation forecasts, analysis and load relief, performing short circuit studies, performing breaker duty analysis, developing transmission and distribution station and feeder designs, reviewing large customer demand proposals. Mr. Mousa is responsible for all Distributed Energy Resources technical evaluations and interconnection agreements.

Mr. Mousa is the Founder/CEO of The Electric Bridge Consulting firm assisting large and small utilities, colleges/universities & consulting firms by providing electric utility services, educational/training services, consulting services, leadership seminars, career consulting, lecturing services, electric professional engineering courses & national & international webinars. 

Mr. Mousa was responsible for the short term, long term (1/5/10/20/30 years), and emergency planning for the area substation, transmission / sub-transmission feeders and the 4 kV system at Consolidated Edison. He has conducted several studies on the impact of electric vehicles, distributed generation, steam to AC conversion, energy efficiency models, and R&D initiatives on the distribution and transmission system.

Mr. Mousa was the project manager for a SCADA GE XA21 Energy Management System and the project manager and project engineer for President Obama’s Department of Energy stimulus grant for Consolidated Edison’s 4 kV system.

Awards include the 2009 3rd Quarter Distribution Engineering ALVA Award for 21st Century Leader, the 2012 “Sustain Energy Reliability” Team Award, and the 2013 Excellence in Design and Genius Engineer (EDGE) Award Nominee for “Developed Load Calculation Tools for System and Transmission Operations.” He has over eight years of experience in providing training in a wide range of subjects including PSS/E, 4 kV systems, distributed generation grid adoption, system operation outage analysis, transformer ratings, voltage studies, basic and advanced power flow, intermeshes, phase angle studies, capacitor bank impact on the grid, smart grid, plant information (PI), post contingency analysis, voltage reduction, and conservation voltage optimization. Mr. Mousa received his Bachelor's Degree in Electrical Engineering from Stony Brook University and later a Master's Degree in Electrical Engineering from Manhattan College and has completed the Siemens PTI Distribution and Transmission courses.
