Network Optimization


Improving network energy efficiency is a process that takes time and investment

The Challenge
For Cable Operators, the Access Network (AN) is generally the largest consumer of electricity in a cable system, representing 60-70% of the total electricity usage. Due the associated costs and long ROI, improving AN energy efficiency requires a long-term strategy that affects existing network performance, and avoids future energy costs by incorporating energy efficiency into new network architectures and plans. To accomplish this, Coppervale employs a stepped process to help Operators understand their current state, set performance goals, create and/or develop programs to achieve improvement, measure improvement over time, and plan for the future.

Establishing Metrics
Proper and appropriate metrics provide Operators with a way to gauge overall operational performance. Coppervale has been an active contributor to the development of Access Network metrics for the ETSI 205-200 and SCTE 211 specifications published in 2015. We know these metrics, understand how to measure them, and most importantly, how to use them effectively to improve energy efficiency in the plant. As your partner, we will help you understand how to analyze AN energy data beyond these metrics for a deeper understanding of performance and opportunity.

Creating Baselines
A baseline establishes the “before” benchmark by capturing the total energy use and productivity prior to making improvements. By creating benchmarks, Operators can compare various networks, evaluate on-going performance, and determine improvement opportunities.

Operationalizing the Metrics
You can’t improve what you don’t measure—it is important to continuously measure performance over time to understand the impact of any investment. Coppervale can convert your initial benchmarking into a Continual Measurement Process for the purpose of tracking and analyzing energy data. We will work with you to create company-wide KPI’s to drive and manage performance internally, and design tailored dashboards to report the information customized to your organization’s needs.

Our wide experience in auditing and analyzing AN’s gives us unique perspective and understanding of the AN energy profile. We use that unique understanding to operationalize measurement and reporting systems that reduce cost and impact on the company, while providing Operators with the critical data needed to manage and improve energy efficiency in AN’s over the long term.

Using the Metrics to Drive Energy Efficiency in Existing Plant
Utilizing techniques and metrics outlined in the Operational Practice for SCTE 211, high-performing AN’s can be identified and best practice ideas can be leveraged across the enterprise. In the example above, Coppervale uses two metrics, Energy per Consumed Byte (EPCB, in kWh/TB), and Watts per mile of Plant (WPM), to characterize various AN’s within a company’s footprint. We compare and rank-order performance, then identify the poorest performers for targeted action.

Once targets are identified, efficiency can be achieved in the following ways:
•    upgrading power supplies to more efficient models
•    upgrading to higher voltages
•    improving power supply loading

While these projects have a very lengthy ROI, Coppervale can show you how to combine these techniques with ongoing network upgrades, maintenance and operations to reduce the pay back time and achieve improvements as quickly as possible.

Using the Metrics to Drive Energy Efficiency in New Build
As Operators build new plant, they have the opportunity to integrate energy efficiency into their processes. Whether guiding Operators towards more efficient and cost-effective architectures and equipment selections, or finding the best ways to include energy efficiency in plant design and build processes, Coppervale can ensure the new plant you build achieves state-of-the-art Access Network energy efficiency.
