The opening issue of the 2018 Journal of Energy Management has three articles for your review. First is the concept of an infrastructure headway energy opportunity which looks at ways to address the prep and preservation of the critical space headroom. Next, research findings are presented that illustrate various causes of critical facility outages, especially slack of power. We conclude with a follow-up study about using computational fluid dynamics modeling to assess cooling in the critical facility.
From The Tech Refresh and the Nega-Watt: Common Sense Powering at Comcast by Ben Strunk
Within this first 2019 Journal of Energy Management we evaluate some strategies and technologies including Grid over the Internet of Things (GoIoT) demonstrating two distinct use cases for cable’s participation in GoIoT. Next, research regarding the reduction of RF signal loading of a cable network in times of low traffic is presented. Another Outside Plant (OSP) energy cost reduction strategy includes utilizing assets such as battery storage that traditionally were only used for back-up power purposes when the utility grid failed. And finally, we cover how to right size HVAC units by utilizing standards and various ratios to evaluate both heat load and comfort.
From Grid Over The Internet Of Things™ by Robert Cruickshank III, PhD
In this September 2019 important issue of the SCTE Journal of Energy Management our authors evaluate the strategy of microgrids for cable, managing incorporation of renewable power with little to no capital expense, advantages of phase change materials to combat cooling costs, access network advanced design using artificial intelligence, and airflow management to optimize cooling needs.

Three articles are available in our September 2020 edition. The first examines precision air vs. comfort cooling as it relates to critical facilities. Next, we present a method for approaching how cable operators can move forward with fleet electrification. The third paper examines a total cost of ownership (TCO) framework for determining the best method for delivering the 10G networks. Finally, in a letter to the editors, the importance of managing company diesel fuel supply chain as it relates to our targeted maximum availability of service is discussed.
From Drive to Sustainability: Electric Fleets Contribution Toward Zero-Emission Goals and Operational Savings by Paul Stith
SCTE Standards Journal consolidates into one package with multiple topics including Energy Management.
Network Power Considerations for 10G Enhancements
Rob Anderson of EnerSys discusses assuring the availability of additional, reliable, and intelligent power for the near future 10G-capable access network is both essential and challenging since network architectures are evolving and 10G enabling technologies are still being developed . In this paper we review two specific access network upgrades through the lens of network power. First, distributed access architecture (DAA) optical nodes (ONs) bring higher bandwidth closer to consumers. Remote PHY (R-PHY) nodes are one example of a DAA implementation . R-PHY nodes bring new powering challenges to the access network including the need for high quality, resilient power. Second, recent operator investments in CBRS RF spectrum are good indicators that access network powered small cell radio area networks (RANs) will soon be scaling up. New radio installations come with new power level and voltage reach challenges for the access network.
Achieve Power Savings in a DOCSIS 4.0 network with a Distributed Gain Architecture
Jan Ariesen of Technetix discusses one of the main elements of the new DOCSIS 4.0 specification: the ability to expand network capacity to 1.8 GHz, and nearly double the capacity of many current HFC networks. What remains a subject of debate is the best way to meet the specification and how much will it cost? The primary options include extended spectrum DOCSIS (ESD) and full duplex DOCSIS (FDX). Which one do you choose; which is the most futureproof, flexible, and reliable option that will give you more capacity in your network? How much will the chosen solution cost in labor/truck rolls for re-spacing amplifiers, and most importantly - how much power will it use?
Optimization of Electric Load Shaping, Sensing, and Forecasting A Guide to Operational Savings and New Business Models
Dr Robert Cruickshank III of GRIDIoT® and other co-authors discusses building more power generation, transmission, and distribution infrastructure hasn’t resulted in a more resilient grid or more reliable power—but it has raised the cost of electricity. To reliably support broadband operations and enable new business models, what's needed are new solutions that monitor the grid and enable the demand for electricity to be shifted in time to follow the cleanest and lowest-cost supply. Time-shifting creates economic value by discouraging consumption at certain times and encouraging consumption at other times, thereby creating virtual power plants that optimize and extend the life of existing grid assets. Furthermore, time-shifting reverses the supply-follows-demand relationship by allowing flexible demand, such as battery storage, to anticipate and follow supply. The goal of this work is to empower the broadband industry with software-centric technologies that increase network reliability and reduce the cost of broadband operations while spearheading profitable business models that scale quickly to modernize the global electric utility ecosystem while reducing harmful heat and carbon emissions.
