Case Study: Technical Assurance Agent (TAA) for Elexon

What It Is

The Technical Assurance Agent (TAA) service provides independent oversight of performance, data integrity and system compliance within the Balancing and Settlement Code (BSC) framework. Acting on behalf of Elexon, the TAA plays a critical role in strengthening confidence across the UK electricity settlement landscape.

The service ensures that market participants, central systems and settlement processes operate as intended — identifying risks, validating controls and providing evidential assurance across complex, high-value market activities.

C&C Group delivers the TAA function with structured governance, technical depth and regulatory precision.

Scalable by Design

The electricity settlement ecosystem is dynamic, data-intensive and subject to continual reform. C&C Group delivers the TAA service through a scalable assurance model capable of adapting to regulatory change, system upgrades and evolving market structures.

Our approach combines structured audit methodologies, data-driven analysis and controlled risk assessment frameworks. We maintain the flexibility to respond to emerging settlement risks while ensuring consistency and rigour across assurance cycles.

Through robust tooling, disciplined oversight and scalable reporting processes, we ensure the TAA service evolves in line with BSC modifications, system enhancements and performance monitoring reforms.

E2E Value and Benefits

C&C Group provides end-to-end assurance services across the TAA remit, including:

· Independent technical performance reviews
· Data integrity validation and control testing
· Risk-based assurance planning
· Investigation of performance anomalies
· Structured reporting aligned to BSC governance requirements
· Evidence-based recommendations for corrective action

Our service strengthens transparency and accountability within settlement operations. By identifying control weaknesses and performance gaps early, we help mitigate systemic risk and protect the integrity of the electricity market.

We deliver clear, actionable insight — not just audit findings — enabling Elexon to make informed, evidence-backed decisions.

Strategic Impact

The integrity of electricity settlement underpins financial flows worth billions of pounds annually. Effective assurance is therefore fundamental to maintaining market confidence and regulatory credibility.

C&C Group’s delivery of the TAA service reinforces trust across market participants, central systems and governance bodies. By providing independent validation and structured oversight, we support the robustness of settlement processes and reduce the risk of material error or systemic failure.

Our expertise in electricity market operations, data governance and regulatory frameworks ensures that assurance activity is both technically rigorous and practically grounded.

Outcome for Elexon

Through C&C Group’s stewardship, the TAA function operates as a disciplined, responsive and strategically aligned assurance capability. Elexon benefits from clear visibility of performance risks, defensible audit evidence and structured reporting that supports strong governance.

The result is a strengthened settlement framework, improved market confidence and a resilient assurance function capable of evolving alongside the future of the UK electricity market.
