Elexon selects BJSS to support data workstream of Helix programme

22 February 2022 Consultancy.uk 3 min. read

Elexon has selected consultants from BJSS to support a major transformation, which could deliver net benefits to British energy consumers of more than £4 billion. The programme will also help decarbonise the electricity industry.

Traditionally, electricity used by smaller businesses and households every half hour has been estimated, as it was previously considered too expensive to install meters to provide readings so regularly. Estimates of their usage are updated as meters are read, meaning that the current settlement process takes over a year to complete.

In 2017, however, energy regulator Ofgem announced a review on whether the whole electricity market should move to half-hourly settlement. Since then, smart meters have been rolled out in homes and businesses, recording consumption every half hour – meaning the whole electricity market could be settled quickly and accurately every half hour.

Elexon manages Great Britain’s electricity Balancing and Settlement Code (BSC), comparing how much electricity generators said they would produce and suppliers said they would consume with the actual volumes that are generated and used, making sure that everyone is paid or billed accurately for any differences.

The Helix Programme

As it prepares to facilitate Market-wide Half Hourly Settlements (MHHS), Elexon is initiating the Helix Programme, transforming its central systems and infrastructure.

Supporting the digital transformation programme is BJSS, which has been selected as a lead consultant for the data workstream. 

The systems redevelopment involves the creation of new services and a new system which will be key to unlocking the benefits that electricity suppliers expect of Elexon, including faster, more accurate settlement. To support this move, BJSS’ team of specialists will draw upon its expertise within the energy industry, and extensive experience in delivering secure, scalable and reliable data platforms.

Ben Cooper, Sales Lead for BJSS’ Energy, Commodities & Utilities Practice, said, “We are delighted to be helping Elexon deliver an important programme of work which supports the redevelopment of systems that play an essential role in the electricity market.”

“We look forward to working with the great team at Elexon, and the other suppliers involved in the programme, to decarbonise the industry.”

MHHS is suggested to deliver positive outcomes for UK consumers due to reduced overestimations, leading to less wastage, reduced environmental impacts, and enhanced security of supply. Once applied, it is expected to deliver net benefits to British consumers of up to £4.5 billion between 2021 and 2045 – enabling enhanced management of energy distribution and consumption, and resulting in better and cheaper results for energy customers.

Meanwhile, MHHS will also be a key enabler in helping Britain achieve its net zero ambitions. The transition can support the decarbonisation of the energy sector in a cost-effective manner.

Victoria Moxham, Director of Customer Operations at Elexon, explained, “Moving to MHHS is a key change in the energy sector which will help enable the innovation and change needed to reach net zero. Elexon is investing in redeveloping BSC central systems so that we can receive and process the exponential increase in half-hourly data that we will be required to process once MHHS is implemented.”
