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
