CP531  Energy Benchmarking to Reduce Operational Costs Water & Wastewater

Benchmarking energy efficiency is a ‘must do’ activity that all water companies need to undertake to ensure that energy usage and costs are transparent and comparable with industry ‘norms’.  However the process can be complicated and require onerous data gathering programmes – is there a simpler approach?

Through its implementation, energy benchmarking provides the means to ‘track down’ inefficient sites or processes so that excessive costs can be identified and eliminated. The benchmarking process also highlights examples of best practice which can be used to reduce future energy costs by informing capital delivery programmes.

Experience has shown that there can be a number of barriers to implementing such schemes, for example, excessive data requirements, data gathering too onerous, data comparison methodology too complex, and sub-metering not in place.

The aim of this project is to:

  • simplify the energy benchmarking process so that the principal barriers are removed.
  • support the application of the process to ensure effective implementation.

BUSINESS BENEFITS TO CLIENTS

  • Significant reduction of energy costs and GHG emissions through identification and subsequent elimination of inefficient sites or processes.
  • Reduction of future energy costs through informed asset and process selection.

WORK PROGRAMME

  1. Develop simplified energy benchmarking methodologies for sub-metered and non sub-metered sites.
  2. Develop a simplified energy benchmarking website for uploading and benchmarking data.
  3. Develop additional guidance for energy data extraction, collection and website upload.
  4. Demonstrate implementation of the new, simplified process at one site (water or wastewater) per contributor to prove effectiveness and ease of use of the new process.
  5. Provide implementation support such as the use of portable, ‘clamp-on’ technology and options for retrieval from SCADA or data archive systems.

PROJECT OUTPUT AND IMPLEMENTATION

  • New, easy to implement energy benchmarking methodology.
  • Demonstration of process to support implementation.
  • Guidance on data collection and extraction from companies’ data archive.
  • Two workshops including discussion of case studies and hands-on training.
