DIGITAL EXPERIENCE

High energy prices demand a better digital customer experience

A customer portal 2.0 and an energy app that do more than just display consumption: these are the two ultimate ways for energy suppliers to improve their digital customer experience. In this blog, we provide a bit of context, concrete ideas, and two successful real-world examples.

Fluctuating energy prices and a heightened awareness around sustainability are raising your customers' expectations. They are setting the bar higher. While a correct invoice used to be enough, customers now expect 

  • real-time transparency, 
  • in-depth insights,
  •  and proactive guidance.

For you as an energy supplier, this implies a shift: from a traditional supplier to a digital partner who helps customers better understand and manage their energy usage. 

Yet, for many suppliers, the interaction remains limited to sending invoices and offering a basic portal. In a market with dynamic pricing, smart meters, and new energy services, that model is no longer sufficient.

How do you go from an energy bill to real insight?

For customers, an energy bill often arrives too late to adjust their behavior. Moreover, most invoices don't include tips to reduce consumption, let alone personalized advice.

A solid digital customer portal and a user-friendly energy app offer the solution. They make it possible to give customers faster and clearer insights into their consumption, costs, and pricing. In practice, however, we notice that most current portals and apps don't go beyond the absolute basics.

How about your digital experience?

Does your portal mainly show invoices? Does your app display consumption without translating this data into actionable insights? That’s a missed opportunity. When you, as a supplier, succeed in presenting energy data in an understandable way, you increase both the trust and engagement of your customers. This presents a massive opportunity.

Make a difference with your customer portal and app

Many energy suppliers already have strong back-office systems, such as Cogenius or Ferranti MECOMS 365. But often, the link to the customer is missing: a digital layer that easily visualizes complex data.

This is where user-friendliness—UX research and service design—plays a crucial role. ACA Group’s specialized teams analyze customer needs and design digital interactions that make energy information clear and actionable.

We don't believe in a risky 'big bang' implementation. That is why we use a pragmatic three-phase growth model. This allows us to build a new customer portal or energy app step by step, with each phase immediately delivering value. This way, your investment yields faster returns, and we maintain control over the rollout toward a fully-fledged, full-service customer experience.

For portals, we opt for a modern, mobile-friendly architecture. This allows us to easily extend the same platform to a native iOS and Android app. It makes it possible to launch mobile applications at a fraction of the traditional development costs, without compromising on performance.
