National Grid is an international electricity and gas company based in the UK and northeastern USA that 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). National Grid Electricity Transmission (NGET) owns and operate the electricity transmission network in England and Wales, with day-to-day responsibility for balancing supply and demand, and as such is responsible for nearly 4,500 miles of overhead lines in the UK alone. 


Under the terms of the RIIO regulatory period, OFGEM required NGET to prepare an annual Regulatory Reporting Pack in 2016 that would demonstrate the company’s performance against its agreed Capital Investment Plan. To do this, NGET had to align the data for the financial year 2015-16 between its finance system (SAP) and its Asset Management business system (PIER).

The Enzen

The Enzen team worked closely with NGET to manage, integrate and co-ordinate complex financial reports. This included adding financial control disciplines like auditing, version control and change management. The Enzen team also managed reconciliation, including scope, design, resource planning, execution, assurance, close out and lessons learned. Finally, Enzen designed a customised model to reconcile the two sets of data within the timescales set by NGET.

and Value

The result was a transparent and detailed model that gave NGET a sustainable reporting mechanism to use as part of its business-as-usual processes. Thanks to the model, NGET could efficiently analyse, process and easily interpret information. Through integrated working and communication between different departments, the speed of query resolution and data consistency were also improved. And following the deployment of programme-wide project controls, NGET was able to access project status information, glean valuable insights, improve accountability, intervene earlier where necessary and maximise performance.
