Overview

kSIST FprES 205 200-3 V1.0.0:2017 is a standard developed by SIST under the framework of ETSI to define global Key Performance Indicators (KPIs) for energy management in ICT sites. This standard covers the implementation and monitoring of energy management performance in operational infrastructures such as data centres, fixed broadband, and mobile network sites. The document focuses on supporting efficient energy use, optimizing operational performance, and enhancing the sustainability of ICT facilities by providing a framework to measure and evaluate key energy-related metrics.

ICT sites are rapidly becoming significant contributors to global energy consumption and greenhouse gas emissions. With increasing regulatory attention and growing market expectations for sustainable operations, deploying standardized energy management indicators is now essential for site operators and industry stakeholders. This standard addresses these challenges by providing consistent metrics for evaluating energy consumption, task efficiency, energy reuse, and the use of renewable energy in ICT environments.

Key Topics

kSIST FprES 205 200-3 V1.0.0:2017 focuses on the following core energy management KPIs for ICT sites:

• Energy Consumption (KPI EC): Measures total energy required for the operational infrastructure of ICT sites, including all systems necessary to maintain intended service levels such as cooling, power distribution, security, and safety.
• Task Efficiency (KPI TE): Assesses the efficiency ratio of energy used by IT equipment to the total energy consumption at the site, providing insights into the effectiveness of energy utilization by core ICT assets.
• Energy Reuse (KPI REUSE): Quantifies the proportion of energy that is reused for external purposes (e.g., heating), promoting initiatives to repurpose waste heat and improve overall sustainability.
• Use of Renewable Energy (KPI REN): Indicates the share of energy sourced from renewables compared to total energy usage, supporting organizations in tracking and increasing their renewable energy adoption.

Each KPI is defined along with guidance for measurement, scale, evolution across the site lifecycle, and calculation methodology to ensure consistent, comparable results.

Applications

Implementing global energy management KPIs as outlined in this standard provides several practical benefits for ICT operators, facility managers, and sustainability professionals:

• Performance Monitoring: Enable organizations to track and benchmark energy performance across multiple ICT sites, data centres, and network operations facilities.
• Efficiency Improvement: Identify opportunities to reduce energy consumption, enhance equipment task efficiency, and maximize energy reuse.
• Sustainability Reporting: Support compliance with regional and international directives (such as EU regulations) and demonstrate progress towards energy and carbon reduction targets.
• Investment Planning: Facilitate data-driven decision-making for capital investments in energy-saving technologies and renewable energy integration.
• Stakeholder Communication: Offer transparent, standardized metrics for communicating energy performance to clients, regulators, and internal stakeholders.

By following the guidelines of this standard, ICT operators can align their energy management practices with international best practices and strengthen their environmental responsibility.

Related Standards

kSIST FprES 205 200-3 V1.0.0:2017 references foundational and complementary standards to build a comprehensive framework for ICT site energy management:

• ETSI ES 205 200-1: General requirements for global KPIs in operational infrastructures.
• ETSI ES 205 200-2-1: Specific requirements for data centres.
• ETSI ES 205 200-2-2: Specific requirements for fixed broadband access networks.
• ETSI ES 205 200-2-3: Specific requirements for mobile access networks.
• CENELEC EN 50600 Series: Standards for information technology – data centre facilities and infrastructures.
• Recommendation ITU-T L.1300: Best practices for green data centres.
• European Commission DG JRC Code of Conduct for Data Centre Energy Efficiency: Guidelines supporting energy-efficient data centre operations.

Adopting kSIST FprES 205 200-3 ensures compatibility with these established standards and supports organizations in implementing holistic, standardized energy management across ICT infrastructures.

Introduction
Information and communication technology (ICT) sites constitute one of the most important areas of the worldwide
growing energy consumption. They are responsible for at least 2 % of the worldwide greenhouse gas emissions, still
growing.
Energy management performance of ICT sites is an important matter. It is now essential if not vital to implement
commitments in order to reduce the energy consumption by ICT sites.
Further to the 1997 Kyoto protocol [i.7], the European Commission has issued, and will issue, Directives in order to
improve energy management of networks, sites included, of whole industry sectors.
Therefore suppliers and users of ICT equipment are required to implement "Green" tools (indicators, recognized Green
levels) to monitor the efficiency of their greener ICT sites.
Consequently, the first target of ETSI ATTM has been the development of this ETSI standard (ES) with support of ISG
OEU members (ICT world Users) in order to define those tools.
The KPI presented in the present document is an answer to requirements by end users and European Community to
justify a global sustainability level for ICT sites. On the side of the ICT site owner, it assesses an energy management
performance level; on the EC side, it allows a follow-up for the global adjustment of policy for sustainability of ICT
industry.
The present document presents the Objective KPIs defined in standard ETSI ES 205 200-2-1 [2] for data centres,
ETSI ES 205 200-2-2 [i.10] for fixed networks, and ETSI ES 205 200-2-3 [i.11] for mobile networks and uses them to
define a Global Key Performance Indicators (KPI) allowing the evaluation of performance of energy use management
in ICT sites.

1 Scope
The present document defines field implementation of a so-called Global Key Performance Indicators (Global KPI)
enabling the monitoring of performance of energy use management in all ICT sites including, but not limited to, data
centres and operator sites.
Performance of energy management is dealt as independent layers. The present document addresses performance of
hosting infrastructure that allows normal functioning of hosted ICT equipment, including climatic conditions, security
and safety. The present document does not deal with other layers such as performance of ICT equipment itself,
performance of usage of available processing power, and layers related to final service delivered (e.g. processing power
required per built car) or overlay layers (e.g. final energy required per built car).
The present document deals with final energy consumption by ICT sites or group of sites, use of energy from renewable
source and energy reuse. It does not deal with GHG gas emissions that will be taken care of in other parts. Neither does
the present document deal with efficiency of power generators or adequacy of performance to given climatic conditions
or availability requirements.
Energy consumption should not to be confused with power generation. Only energy actually consumed by the ICT site
should be counted. Use of excess locally generated power is out of the scope of the present document.
The present document does not address the whole sustainability aspects related to ICT sites. Other aspects such as
power management, global environmental footprint of the ICT site construction, operation and decommissioning are not
dealt with in the present document and should be considered.
The Global KPI alone is not designed for comparison of ICT sites or group of sites. It does not define an ICT site as
good or bad unless combined with other parameters considered relevant for a comparison, such as local climatic
conditions, availability requirements or purpose of ICT site.
Several standards and technical documents have been taken into account during the development of the present
document including EC Mandate M/462 [i.1], ETSI ES 205 200-1 [1], ETSI TS 105 174-1 [i.6], ETSI
TS 105 174-2-2 [i.2], CENELEC EN 50600 Series [3], Recommendation ITU-T L.1300 [i.4], and EC DG JRC Code of
Conduct for Data Centres [i.3] and [i.5]. It was initially built based on the position paper [i.13] by ETSI ISG OEU.
The present document addresses in a simple way the following objectives defined in standard ETSI ES 205 200-2-1 [2]
for data centres, ETSI ES 205 200-2-2 [i.10] for fixed networks and ETSI ES 205 200-2-3 [i.11] for mobile networks:
• energy consumption;
• task efficiency;
• energy reuse;
• renewable energy.
