SCTE Energy Standards and Operational Practices
The SCTE Standards Program develops standards and operational practices in several key areas to improve the application of environmentally friendly and sustainable procedures and products, to create solutions that lower overall costs and increase overall performance. These documents are consensus-developed and SCTE Engineering Committee approves SCTE standards. Many of these standards have also been approved by the American National Standards Institute (ANSI) and are so designated.

Also included are advanced cooling technologies such as air side and water side economizers.
Cable operators run a distributed network covering thousands of miles connecting facilities to customers and facilities to facilities. This network requires maintenance, upgrades, installation and repairs. Also, new cable subscribers require visits to their site ensuring proper deployment of equipment and turn up of service. All of this is accomplished via a fleet of vehicles that if not managed optimally can impact both the company’s bottom line as well as environment.
This document presents a five tier classification approach to provide cable operators with a framework in which to categorize facilities and critical infrastructure, prioritize investment decisions, establish availability expectations, and to define performance levels for the cable industry.
This document is meant to apply to the cable industries facilities including critical facilities, office space, call centers and warehouses. The scope of this document does not include the outside plant.

SCTE 253 2019 Cable Technical Facility Climate Optimization, Operational Practice: Understanding Set Point Values, Part 1
This operational practice is intended to educate individuals working in broadband communications critical facilities on what cooling system set points are and how adjusting set points can impact cooling system operational efficiency. The objective is to provide engineers, technicians and contractors a basic understanding of those impacts so set point adjustments will not be done casually but instead be part of the overall goals to optimize the efficiency of the cooling and heating systems without risk of creating conditions which could cause information and communication technology (ICT) equipment to fail. There are significant implications with respect to the operational efficiency of the facility that can result from changing cooling system set points for the wrong reasons. A better understanding of cooling system set points will enable people working in critical facilities to avoid actions that may prove detrimental to the facility operation.
This standard defines in simplistic terms how to create, transmit, and act upon a forecast optimum load shape (OLS) that may be used to manage the charging of electric vehicles (EVs) and facility batteries, or otherwise used to manage electrical load. This OLS standard provides for end-to-end, generation to load control of the electric power grid towards the goals of reducing energy costs, maximizing the use of renewable energy, and accelerating the adoption, monetization, resiliency, and societal benefits of microgrids, EVs, and batteries.
