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.

Find topics relevant to your organization, recommend new topics, and join the SCTE Standards Program to help shape the future of energy technologies in cable.

SCTE 287 2023 Right-Sizing Outside Plant Power Supplies

In a cable broadband provider’s effort to become more energy efficient there is an opportunity to right-size an expanding arsenal of ferroresonant power supplies and to ensure the most efficient placement of those power supplies.

By increasing efficiency in placement, providers may benefit from reductions in operational and capital expenses, reduced Scope 2 emissions through less transmission loss to inefficient transformation, and extended runtimes. This creates potentially less need to deploy portable generators which can impact Scope 1 emissions.
