We use the term "backup" power system to convey the complexity of electrical power sources when the primary source is not used; either as a scheduled or an unscheduled event. We review the Second Draft of the 2024 NFPA 110/111 and the First Draft Reports for balloting and release for public review ahead of the August 24 deadline for public comment on the 2026 National Electrical Code.

Sporty weather season in the United States inspires a revisit of best practice for designing, building and maintaining the systems that provide limited electricity when the primary source fails. Today we review the systems that backup power to data centers; in particular, the systems that keep data centers cool. Public comment on the Second Draft of the 2025 revision will be received until March 27, 2024.
Electropedia is produced by the world’s peak standardization organization that oversees 214 technical committees that provide a neutral and independent platform where agreement can be found on electrotechnical solutions with global relevance and reach. Consultation on revisions to the definitions found in IEC 60050 – Part 601: Generation, transmission and distribution of electricity closes April 16th.
Educational settlements are the closest many people come to feel at home in beautiful surroundings. The catalog that informs the safety and sustainability of these "cities-within-cities" changes 100 to 1000 times per day. By design titles are unstable, time-sensitive and copyright protected. We explore the action continuously; assign priorities, then schedule a separate teleconference to formulate responses to public consultations. Daily colloquia topics appear on our CALENDAR.
This title sets the standard of care for construction, operation and maintenance of power and telecommunication infrastructure on the supply side of the point of common coupling. It is the first title to reach for when disasters happen; with most public utilities bound to its best practice assertions by statute. Now seeking experts to prepare the 2028 revision.,
As long as electric power is carried through wires we will find drama about who pays for the wires. Spirited debate on this topic happened International Energy Conservation Code Public Comment Hearings. Today we revisit the concepts in play and continue to track their trajectory through federal, state and local energy and mobility regulations. EV concepts track all across the ICC catalog. Public hearings on proposals for the Group A tranche of titles will happen in Orlando, April 7-16.
Links to the most recent public hearings; the most recent on February 28th hosted by the Grid Development Office. Previous discussions linked here are largely centered on electric supply, transmission and distribution system reliability. Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with updates to IEEE codes, standards and recommended practices.
The University of Michigan district energy microgrid worked flawlessly before microgrids were cool.
