A stable electricity supply is critical for the smooth execution of this major international event. Uninterrupted power is essential for conference venues, accommodation, transport, and communications infrastructure.<\/p>\n\n\n\n<p><em>Wondering how authorities are gearing up for safe global hosting?<\/em> <strong><a href=\"https:\/\/www.gauteng.net\/whats-on-g\/gauteng-task-group-2025-g20\/\">Gauteng Community Safety Forms Task Group to Manage Security and Preparations for 2025 G20 Summit<\/a><\/strong>.<em> Tap to read the full story and stay informed.<\/em><\/p>\n\n\n\n<div id=\"gaute-3212224148\" class=\"gaute-inbetween-content gaute-entity-placement\" style=\"margin-top: 30px;margin-bottom: 30px;margin-left: auto;margin-right: auto;text-align: center;\"><div class=\"gaute-adlabel\">Advertisement<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-1852772760112594\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-1852772760112594\" \ndata-ad-slot=\"1819787043\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"true\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\" id=\"h-electricity-supply-in-johannesburg-eskom-and-city-power\">Electricity Supply in Johannesburg: Eskom and City Power<\/h2>\n\n\n\n<p>Johannesburg\u2019s electricity supply is <a href=\"https:\/\/www.joburgetc.com\/best-of-johannesburg\/city-power-vs-eskom-joburg-electricity-2025\/\" target=\"_blank\" rel=\"noreferrer noopener\">managed through<\/a> a partnership between Eskom and City Power, the municipal utility owned by the City of Johannesburg. City Power supplies most metro areas, such as Sandton, Randburg, and the Johannesburg CBD. Braamfontein and Rosebank are also included. Eskom continues to supply historically underserved areas, such as Soweto, Orange Farm, Diepsloot, Finetown, and parts of Ivory Park.

This improvement has enhanced Eskom\u2019s ability to reliably meet winter and peak electricity demand. Eskom continues to focus on routine maintenance. The aim is to optimise the <a href=\"https:\/\/www.eskom.co.za\/wp-content\/uploads\/2023\/10\/Eskom_sustainability_report_2023.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Energy Availability Factor<\/a> (EAF), which currently averages around 63%. Emergency reserves are also being deployed as needed to ensure continued reliability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-understanding-power-factor\">Understanding Power Factor<\/h2>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><a href=\"https:\/\/www.eskom.co.za\/eas\/wp-content\/uploads\/2021\/05\/Power-Factor-Basic-Overview-Factsheet-Final.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Poor power factor<\/a> adds to the facility inefficiencies, increases operating costs, increases plant breakdowns, and subsequently increases maintenance costs. Many electricity utilities charge an additional fee if a facility\u2019s power factor is less than a specified nominal, for Eskom this is 0.96. Low power factor also reduces the electrical system\u2019s distribution capacity by increasing current flow, thereby causing voltage drops. By improving the power factor, customers should be able to increase their productivity without requiring additional electrical capacity.<\/p>\n\n\n\n<p>Poor power factor is caused by inductive loads (such as transformers, electric motors, and high-intensity discharge lighting), which are a major portion of the power consumed in industrial complexes. Unlike resistive loads that create heat by consuming kilowatts, inductive loads require the current to create a magnetic field, and the magnetic field produces the desired work.<\/p>\n<\/blockquote>\n\n\n\n<div id=\"gaute-2185155079\" class=\"gaute-inbetween-content gaute-entity-placement\" style=\"margin-top: 30px;margin-bottom: 30px;margin-left: auto;margin-right: auto;text-align: center;\"><div class=\"gaute-adlabel\">Advertisement<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-1852772760112594\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-1852772760112594\" \ndata-ad-slot=\"1819787043\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"true\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\" id=\"h-specific-preparations-for-the-g20-summit\">Specific Preparations for the G20 Summit<\/h2>\n\n\n\n<p>In preparation for the G20 summit, Eskom has fast-tracked grid maintenance and load management strategies around Johannesburg. This is particularly true in areas critical to the summit\u2019s venues and accommodation. The utility\u2019s efforts focus on reinforcing transmission lines and substations. They ensure sufficient capacity to meet the expected surge in demand during the event.

Collaboration among Eskom, City Power, the City of Johannesburg, and event organisers will provide comprehensive preparedness. These plans address not only power but also transport, security, and communication networks.
