PD Ports in Middlesbrough has partnered with IMServ to provide automatic measuring and monitoring of energy data from 15 electricity substations and switch rooms of its 779 acre Teesport estate.

19 MID-approved (Measuring Instrument Directive) sub-meters have been installed and online access provided to the half-hourly data from these meters through the cloud-based software analytics platform Resource Advisor.

The energy data collection services have provided valuable insights for PD Ports on consumption patterns, time of use data, profiling of energy consumption and generation identification.

PD Ports can now use the metering data to consider altering operations around time of use tariffs and also use the data as evidence for FiT (Feed in Tariff) payments.

The project has allowed for the removal of the labour and transport costs of collecting the meter reads. A major benefit was the identification of their ship-to-shore cranes generating electricity which was being consumed elsewhere onsite.

The resulting data visibility these sub-meters generated allows PD Ports to:

  • Accurately distribute and allocate the consumption information and costs across the site
  • Identify and quantify generated electricity from onsite equipment which was previously not fully understood

The sub-metering data provided boosts individual ship-to-shore crane energy performance and operational analysis through the energy profiles. Furthermore, the data allows for analysis to optimise existing opportunity for energy generation and energy savings, without altering operational processes, therefore, saving electricity and demands on the grid with minimum cost to the business.

Darren Coleman, an electrical project engineer at PD Ports, commented: “This project required a great deal of planning, coordination, flexibility, knowledge and experience both from the office staff and the installation team. IMServ was able to work in collaboration with PD Ports to accomplish this professionally, with diligence and a first-rate regard to health and safety.”

The identification of this electricity generation is a welcome result for PD Ports with the potential to provide a net benefit for Teesport for the full year via a reduction in grid supply of around 131,000kWh, of circa £19,000 and 52TCo2.

IMServ predicts that there is a potential of 11.7MWh of energy generated each year that is not being harnessed from port crane operations. Should all UK container port’s replicate this project, coupled with new crane technology, they could reduce demand on the grid by £1.7million and avoid 4,500 TCo2 annually.
