Stay Ahead in Great Britain's Electricity Market with Secure, Compliant, and Lightning-Fast Data Exchange. 

In Great Britain's fast-moving power market, every second counts. Volue Market Communication UK, formerly Quorum, delivers proven performance for Balancing Mechanism (BM) access and Ancillary Services. Favoured by over half of active BM participants, it combines feature-rich EDT/EDL modules for direct NESO connectivity with full Elexon interface coverage for CVA and SVA Qualifications, ECVNs, Settlement (SAA), and REMIT. In addition interfaces to NESO Ancillary Services auctions provide access Response (DC, DM, DR) and reserve (BR, QR, SR) contracts.
With over 500 BMUs across all asset classes, a 24-year track record in the GB market, and 24/7/365 UK-based support, Quorum is the market-standard platform for BM and Ancillary Services participation. Its modular architecture means you take only what you need — from core EDL/EDT market access to scheduling, settlement reconciliation, and REMIT compliance — with a clear path to expand as your portfolio grows.

USE CASES

You're registering BMUs and need NESO connectivity fast. Instead of waiting 18 months to establish your own EDL and EDT connections, Quorum's IaaS gives you pre-established BM Control Point links hosted across dual UK data centres — so you can reach the GB Balancing Mechanism in weeks. Core Sentinel modules cover every mandatory submission from day one.

You're managing a multi-unit portfolio with time-critical BOA responses, complex dynamic parameters, and scheduling across multiple asset classes. Sentinel's Position Keeper and Dashboard give control room operators real-time visibility across all BMUs from a single interface. SOLV Scheduler automates dispatch planning for CCGT and wind, with direct EDT submission to NESO.

You're consolidating third-party assets as a Virtual Lead Party (VLP, MVLP or VTP), managing ECVN submissions, and coordinating ancillary service bids into NESO's EAC auctions. Sentinel's Elexon interface suite and EAC module handle the full data flow — from bid preparation to result processing — across your entire portfolio.

You need to track cashflows, credit cover, and imbalance positions across a 14-month settlement cycle — and you can't afford to wait for the Elexon SAA I014 publication. SOLV Settlements synthesises your BSC position daily, giving you visibility four working days ahead, with built-in and reconciliation tools.

REMIT requires you to disclose material changes in generation availability in near real time. THOR captures availability events automatically via EDL integration and submits disclosures without manual intervention — reducing regulatory exposure and audit risk as Ofgem scrutiny on REMIT Article 4 continues to intensify.
