Executive Summary: Central Volume Allocation (CVA) Workshop – Solution Options
Elexon’s second CVA workshop focused on developing potential solutions to address the challenges identified through industry engagement. The session provided participants with an opportunity to review emerging solution options, discuss wider policy considerations, and shape the direction of future CVA reform. The workshop forms part of a broader programme assessing whether current CVA arrangements remain fit for purpose in an increasingly complex and data-driven electricity market.
The workshop built upon concerns previously raised by market participants, particularly:
- Heavy reliance on manual and email-based processes.
- Limited automation and system integration.
- Significant dependence on specialist industry knowledge.
- Poor visibility of process status and issue resolution.
- Administrative complexity within registration and market entry activities.
- Operational and financial risks arising from data quality and estimation processes.
Proposed Direction of Change
Elexon presented a strategic vision for a more modern CVA environment, centred on:
- Increased automation of operational processes.
- Greater digitalisation of customer journeys and registrations.
- Improved transparency and process visibility.
- Enhanced data quality controls and validation.
- Better integration between systems through modern digital interfaces.
- Reduced dependency on manual intervention and specialist knowledge.
Participants broadly supported the ambition to create a more streamlined, customer-focused and resilient CVA framework capable of supporting future market reforms.
Strategic Considerations
The workshop also examined external policy developments that may significantly increase pressures on existing CVA arrangements, including:
- Reform National Pricing, which could substantially increase the number of assets operating within CVA arrangements if thresholds are reduced.
- Faster Settlement initiatives, which will require more timely and accurate data processing and reduce the viability of manual workarounds.
There was recognition that current systems were not designed for the scale and flexibility that future industry reforms may require, reinforcing the case for modernisation.
Next Steps
The workshop concluded with agreement that further discovery work and customer engagement are required to refine solution options and determine the most effective delivery approach. Elexon indicated that future activity will focus on:
- Assessing potential funding approaches.
- Undertaking detailed discovery and design work.
- Continuing engagement with industry stakeholders.
- Developing both short-term improvements and longer-term transformational change proposals.
The review is particularly relevant as many of the challenges identified mirror long-standing concerns around complex registration processes, reliance on manual interventions, limited visibility of market activities and growing operational pressures. A successful modernisation programme has the potential to improve efficiency, reduce administrative burden, strengthen settlement accuracy and support future market reforms affecting transmission-connected assets.
The workshop demonstrated strong industry support for modernising CVA arrangements. While current arrangements continue to fulfil their core role, stakeholders agreed that greater automation, transparency and system integration will be essential to ensure CVA remains resilient, efficient and capable of supporting future electricity market developments.
