ERS Platform Overview
The ERS platform is the operational backbone of UK electricity suppliers. Purpose-built for the complexity of the SME and industrial and commercial (I&C) electricity supply market, ERS spans the full supplier lifecycle - from prospecting and pricing through to contracting, billing, metering and industry interaction.
Unlike generic utility software, ERS is engineered specifically for UK market electricity suppliers. It is enterprise-scale, feature rich, and highly configurable, supporting complex multi-site portfolios, sophisticated tariff structures, and demanding regulatory obligations.
ERS can be delivered as a dedicated managed service on Oracle Cloud Infrastructure, combining customer-specific hosting, specialist application expertise, security management, service governance and continuing platform improvement. This provides electricity suppliers with a secure and operationally resilient foundation for mission-critical supply operations.
The hosted service uses a controlled, evolving architecture. Established ERS application and Oracle database capabilities are combined with modern OCI services and newer Kubernetes-based components, allowing platform modernisation to be introduced progressively while protecting operational stability.
ERS supports UK electricity suppliers in meeting evolving market obligations, including industry change programmes, regulatory requirements and operational transformation initiatives.
