From CIS To Customer-To-Grid: Why Utility Customer Platforms Are Emerging

Utilities have long treated customer technology as separate systems: customer information systems (CIS) and billing in one stack; customer relationship management (CRM) and workflow in another; digital engagement elsewhere; and distributed energy resources (DERs), flexibility, or grid-edge coordination in yet another. That model reflected a world in which customer operations were linear: customers consumed energy, utilities billed them, and interactions centred on payments, service requests and complaints.

However, that model is now under pressure – from electrification, active customer participation, affordability concerns and expectations for digital service – all while utilities are being asked to coordinate more dynamically with the grid. In Great Britain, electricity networks secured a record 9GW of flexibility in 2024, with 22GWh harnessed and estimated bill-payer savings of more than £300 million. At the same time, domestic energy debt and arrears have remained at record levels, with Ofgem reporting average arrears above £1,500 for gas and electricity customers without repayment arrangements in late 2025. Customer operations therefore sit at the intersection of service quality, affordability, commercial design and grid flexibility – and the systems supporting them are becoming operationally material.

This is the backdrop to the emerging utility customer platforms market. Rather than a wholly new software segment, it is the convergence of four established categories: CIS and billing; customer engagement; utility CRM; and DER and flexibility. CIS platforms manage accounts, tariffs, invoicing and collections. CRM platforms handle cases, workflows and service coordination. Engagement platforms support portals, alerts and self-service, while DER and flexibility systems connect devices, assets, and grid or market signals. Utilities increasingly need these capabilities to operate as a connected customer-to-grid layer, rather than as isolated applications.

The regulatory direction reinforces this shift. Since June 2022, private domestic and workplace EV charge points sold in Great Britain have been obliged to include smart functionality, so that charging can occur when demand is lower or renewable generation is higher. National Grid Electricity Distribution reported that registered flexibility assets on its platform more than doubled between March 2024 and March 2025, reaching more than 162,800, including 125,000 EV charge points. These developments show why tariffs, billing, customer communications, device activity and network signals can no longer be managed as separate operational domains.

But while the market is converging, it is not standardizing. Some vendors are expanding from CIS and billing – others from CRM and workflow, engagement and energy intelligence, and DER orchestration and connected-home control. For buyers, this creates opportunity and risk: more innovation and adjacent overlap, but less clarity about what the default utility customer platform should be. The practical question is no longer whether utilities need better customer systems; it is which capability anchor should define the platform roadmap.
