Recap of last month’s Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened. Use the login credentials at the upper right of our home page.
We can use our last meeting’s agenda to refresh the status of the issues.
IEEE E&H Draft Agenda 28 May 2024
On site conference agenda:
IEEE E&H Conference Agenda 21 May 2024
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
Toward Performance-Based Building Premise Feeder Design
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
Copper can’t be mined fast enough to electrify the United States
Daleep asked Mike to do a Case Study session on the NEC lighting power density change (NEC 220-14) for the IAS Annual Meeting in October. Mike agreed.
Exterior Campus & Distribution:
Illumination. Gary Fox reported that IEEE 3001.9 was endorsed as an ANSI accredited standard for illumination systems.
2024-ICPSD24-0012 PERMANENT DESIGN OF POWER SYSTEMS Parise
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Harvard Business School: Journal of Healthcare Management Standards
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Papers in Process:
Impedance Grounding Papers 1 and 2 with David Shipp. Previous Discussion:

Over Coffee and Beers:
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
