About the Client

National Gas (formerly National Grid Gas) is responsible for managing the gas transmission system in Great Britain. As part of their regulatory responsibilities, they must comply with the EU REMIT regulation by publishing Urgent Market Messages (UMMs). These notifications provide transparency to the market on events such as outages, capacity restrictions, or other changes that could affect gas flows and pricing.

When regulatory requirements changed, National Gas needed a platform capable of handling structured notifications and delivering them to the market in real time, across multiple channels.

Ensure full compliance with REMIT structured data standards
Improve transparency and accessibility for market participants
Enable email notifications for end users
Deliver a robust, secure, and resilient infrastructure

The Challenge

The original REMIT GB platform launched in 2012, but the regulatory environment has evolved since then. The Agency for the Cooperation of Energy Regulators (ACER) mandated structured XML formats for UMMs, replacing free-text notifications with a strict schema.

This required a complete rebuild of the existing platform to:

Accept structured XML submissions from providers
Validate and store notifications in line with ACER’s schema
Present the data clearly for the public and regulators
Ensure scalability, resilience, and compliance

Modern, User-Centred Design

We redesigned the platform with a clean, responsive interface, ensuring notifications could be easily viewed, filtered, and exported on any device. Time-sensitive market messages are now delivered in a format that is both user-friendly and compliant with regulatory standards.

The design was further iterated in 2024 when National Gas separated from National Grid, reflecting the branding of the new company.

Flexible Publishing Options

While the platform is public-facing and requires no user registration, administrators and approved gas providers can publish notifications in two ways:.

Manual entry via the secure backend dashboard.
XML upload for automatic population of structured notifications.

This ensures providers, regardless of their systems, can deliver compliant messages to the market.

Technical Approach

The REMIT GB platform was engineered for resilience, security, and compliance.

Infrastructure

Two load-balanced application servers provide resilience and continuous uptime.
MySQL database with a hot replica ensures redundancy and rapid recovery.
Sendgrid powers email alerts, while reCAPTCHA protects the system against automated abuse.

How It Works

Approved gas providers submit Urgent Market Messages through a secure admin interface. They can either upload XML files that automatically populate notifications in line with the ACER schema, or enter details manually where automation isn’t available.

Each submission is validated against the structured standard before publication, ensuring compliance and accuracy.

Once published, notifications are made instantly available to the market via:

The public website for browsing and filtering
RSS feeds for real-time monitoring
CSV exports for analysis and record-keeping

Subscribed users are also alerted of the new UMM via email.

Security and compliance

TLS encryption enforced across all communication.
Audit logging ensures full traceability of submissions and publications.
Redundant infrastructure provides business continuity.

The Outcomes

Since launch, the REMIT GB platform has become the trusted source of Urgent Market Messages for the gas market. It has improved transparency, ensured reliable delivery of critical updates, and provided market participants with easy access to the information they need.

These results demonstrate how the platform delivers transparency at scale, reaching a large number of users and ensuring vital market information is communicated quickly and consistently.
