National Grid is an international electricity and gas company based in the UK and northeastern USA. It plays a vital role in connecting millions of people safely, reliably and efficiently to the energy they use. In the UK, National Grid operates under the regulatory regime set out by the Office of Gas and Electricity Markets (OFGEM). 


As a result of tough new cost and efficiency challenges being set by OFGEM to cover the eight years from 2013, a number of initiatives were launched by National Grid Electricity Transmission (NGET) to ensure it was in good shape to meet them. NGET owns and operate the electricity transmission network in England and Wales, and as such is responsible for nearly 4,500 miles of overhead lines in the UK alone. 

The Enzen

To help NGET manage the complex reporting of regulatory performance, Enzen provided a solution that moved baselines, annual business plans and regulatory submission schedules into an assured, controlled data environment. 

A financial model was developed and an internal staging environment created to allow data to be easily loaded into NGET’s Oracle Business Intelligence tools. Modelling for these ‘snapshots’ of asset costs and volumes was flexible enough to reflect the ongoing changes to reporting required by OFGEM.

and Value

Thanks to Enzen’s work, NGET was able to present a single version of the truth through its business intelligence tools. This enabled the customer to review and challenge its plans and measure performance accurately against regulatory targets. 

Equally, the data meant NGET could assess the impact of changes on capital programme objectives and project plans, quantifying the effects in terms of cost and volume and scheduling time for corrective action.

Operationally, Enzen’s solution helped reduced the amount of time needed to gather information and review and report on progress, therefore allowing planning teams to focus on action rather than analysis. What was previously undertaken using multiple spreadsheets from multiple stakeholders could now be carried out by fewer people quickly and with less errors.
