KPI4DC: New Key Performance Indicators for evaluating DC energy sustainability

Today, more than 50% of the world-wide urban population are living in urban areas and more than two thirds of our energy is consumed in cities. The impact of cities on climate change is therefore high. This is one reason why cities need to become smart and optimize the energy consumption of their inhabitants among others according to the availability of renewable energy.

Inside cities, data centres are one of the major consumer groups of energy – specifically of electrical power. Technically integrating data centres into the energy management of smart cities and enabling data centres to take part in renewable energy demand side management schemes are the goals of 8 EC co-funded projects, which share the global aim of increasing renewable energies use, heat reuse and the utilization of Smart Grids.

An 8-projects Cluster (containing 50 partners involved) has been created in order to standardize their procedures as much as possible, to ease the further evaluation of the results obtained. The goal of the Cluster is to ensure that if the projects measure a common variable, they are going to use the same metric measured in the same way. By doing this, the information coming from the results of each project will be directly comparably and understandable by the other members of the Cluster, making feedback gathering way more efficient. All projects are collaborating with DC standardization organizations to define a common metrics framework for DCs. New metrics are promoted to be standardized, the focus being on the energy behaviour of the DC and its alignment to the 20-20-20 European goals.

Metrics that will be presented in the workshop can be classified in the following categories:

  • Flexibility mechanisms in Data Centres: adapting the power/energy consumption in Data Centres, by shifting workloads from peak to valley hours/to times when more renewable or waste energy is available/to lower price hours
    • Demand shifting: workloads are shifted from a time period to another, but always within the same Data Centre.
    • Demand being federated: capitalizing on other Data centres.
  • Renewable energy consumption: maximizing the renewable energy usage
  • Energy recovered: capability of waste energy being reused in the same Data Centre or in another close consumer
  • Primary Energy consumption and CO2 emissions: total primary energy consumption and emissions of the Data Center.
  • Economic savings in the energy expenses: Economic savings that can be obtained in a DC as a result of performing flexibility mechanisms, energy efficiency measures, etc.
  • Capacity planning and capacity management, with the objective to relate the designed and the installed capacity with the actual load. It is important to note that this group of metrics is not going to provide information about the energy efficiency of the DC. However, capacity management is a key issue in modern Data Centres operators.
  • Grid interaction indicators, with the objective of representing the degree of independency of a DC from the electrical system due to the installation of onsite electricity generation.The main objective of this workshop is to present to the different stakeholders the benefits that an appropriate usage of Key Performance Indicators can provide as a tool to assess (and improve) DC energy, economic and environmental behaviour to the IT industry. This also fosters the adoption of energy sustainable solutions in the Data Centre field by the Smart City authorities (policy makers).
