Energy Case Study

MHHS Programme, IMServ

Creating a more flexible electricity market by transitioning to a half-hourly data exchange.

Discover how we delivered success for IMServ on the Market-wide Half Hourly Settlement (MHHS) Programme, the biggest transformation of the electricity market in over 30 years.

Case study background

The Market-wide Half-Hourly Settlement (MHHS) Programme is a major reform initiative within the UK electricity market, led by energy regulator Ofgem and facilitated by Elexon. Its core aim is to improve the accuracy of energy usage and billing by moving all consumers – residential and business – to a half-hourly settlement frequency, based on data collected from electricity meters.

We significantly enhanced IMServ’s quality engineering maturity to support their involvement in this programme, by developing a robust and comprehensive test strategy, implementing organisational quality standards and best practices, and scaling up a team of resources across delivery initiatives to meet critical industry milestones.

Key challenges

Legacy integration
In order to achieve success and realise the benefits of the wider MHHS Programme, IMServ needed to migrate and integrate their on-premise legacy systems into new in-house Cloud & DevOps solutions. IMServ’s strategy, devised by our experts, highlighted and mitigated key pinch points to reduce integration risks.

Externally-led workload and timescales
The programme delivery was underpinned by a complex multi-organisational working environment, with milestones driven by Ofgem and ‘central-party’ stakeholders. This required a careful delivery management approach to retain quality whilst meeting these industry-set timelines.

"Professional, with a diverse set of skills, ... instrumental to our success."

Successful, on-time delivery of key industry SIT milestones

By leveraging our team’s expertise, IMServ were able to successfully complete an 18-month testing initiative comprising six distinct but overlapping phases, well ahead of the industry’s key ‘Ready For Migration’ milestone. We were engaged ahead of the commencement of SIT, managing all elements of component integration, functional, migration, non-functional, operational, and regression testing.

An electricity market fit for the future

Our successful delivery of the various testing requirements underpinning the MHHS Programme has re-affirmed IMServ’s place as a serious contender in the electricity market of the future, extended by the benefits of the half-hourly settlement of consumption data, including greater consumer control and cost savings, a more efficient electricity system operation, and better integration of smart technologies and legacy systems.
