Gatwick Airport LTD Case Study

Gatwick Airport (GAL) has a large portfolio of tenants that occupy space on the airport complex. These range from retail outlets and commercial offices to outsourced airport services. Tenants use electricity, gas and water that is paid for by GAL directly. A network of over 3,000 sub-meters monitor this usage.

GAL's main focus was to increase the accuracy of their energy data, allowing GAL to more reliably invoice their tenants and to provide them with better energy reporting.

To achieve this, GAL needed a partner that could implement a thorough programme of sub-meter data collection, supported by additional meter installations and associated energy management services.

STC's APPROACH

Using specialist energy management software, STC constructed a database of GAL's metering information and tenants. STC then began scheduled meter reading collections, as well as automatically importing AMR data from upgraded sub-meters. 

The resulting data is used to calculate consumption for each tenant, which STC convert into billing files using GAL's own contract rates. Consumption, HH demand profiles and invoice data are made available to GAL and their tenants via an online portal that contains a series of energy and financial reports.

DATA COLLECTION & TENANT BILLING

STC introduced a mobile-based meter reading app and placed smart tags on GAL's meters to enable them to be read quickly and accurately. Data from the app is sent to STC and validated against previous readings to ensure it is correct before invoices are generated.

AMR data and register reads are collected on a day plus one basis. STC manage all aspects of the AMR process, from installation and commissioning through to SIM contracts and fault investigations. AMR data is used in the billing process to produce accurate tenant invoices.

ESTATE MANAGEMENT & ONLINE DATA

STC proactively manage GAL's utility and tenant portfolio. This includes performing site surveys and making assessments of usage in unmetered areas, arranging new sub-meter installations, and handling the change of occupancy process for tenants.

All data is published on STC's online portal. The portal incorporates lists of sub-meter assets, tenant data and invoices, and a suite of reports to display cost and consumption. It also has tools for the management of AMR data and meter readings.

SUPPORT & INNOVATION

STC provide support to GAL on all aspects of the service, and regularly introduce innovations.

For example, STC's energy management software defines walk orders that are reproduced in the meter reading app, to ensure that all of GAL's meters are read regularly and efficiently.

The online portal contains a specially developed dashboard that displays key data for each tenant, such as apportioned monthly cost and consumption, printable invoices and tenancy           information.

The portal also supports GAL's engineering department and allows them to manage overall capacity across the airport.

STC reduce the overall burden of energy related issues on GAL by managing all utilities enquiries from tenants directly, via an integrated, online query system.

RESULTS RECOVERED REVENUE

As a result of STC's service, GAL have not only benefited from a much more effective and streamlined metering and tenant billing process, but have also recovered over £1m of historic unbilled revenue from tenants.

This was achieved by identifying unbilled tenanted areas and tenants that were not paying the correct amount. STC rectified these issues to capture unbilled consumption and increase ongoing revenue recovery.

OTHER BENEFITS

Through the survey process STC identified a number of old meters that were due for replacement. These were added to the metering installation programme to be replaced with AMR meters.

Efficiency savings were also made by project managing the site operations process of new meter installations, meter upgrades, meter reading, and reporting.

In addition, GAL now have a complete and accurate picture of their sub-metered estate and tenant portfolio, and access to high quality metering and billing data.

NEXT STEPS

STC are always looking for ways to enhance their service and introduce features that add value.

For GAL, this will include monitoring real-time data from over 500 panel meters, and further development of the online dashboard to include bespoke reporting for the engineering department.

 

SUMMARY OF SAVINGS

£1,500,000 of revenue recovered and efficiency savings via:

  • Identifying unmetered areas
  • Capturing unbilled consumption
  • Fully managing meter installations and data collection
  • Streamlining tenant billing process
  • Providing online data and reports to GAL and tenants
