Enel Energia App

Enel Energia operates inside a business shaped by regulation, infrastructure, and a customer base that ranges from first-time app users to people managing multiple properties. The app had to work for all of them, inside constraints none of them could see.

App home screen redesign: energy consumption summary, bill status, and quick-action grid shown at a glance on mobile

The Constraint Was Comprehension

Energy is abstract by nature: kilowatt-hours, tariff bands, billing cycles most people never think about until something goes wrong. The interface wasn't the hard part. Making an inherently technical service feel legible to a general audience was.

The real opportunity sat in the gap between what the business needed to communicate (regulatory information, billing accuracy, service changes) and what a household actually wanted to know: am I paying too much, and can I fix it.

Effortless Is a Business Outcome

An app that feels effortless isn't a design nicety here. It's what keeps a customer from calling support, switching providers, or ignoring a bill until it becomes a problem. Every screen had to earn its place by removing a reason to disengage.

The response converted raw consumption data into decisions people could actually act on, rather than numbers they'd scroll past.

Energy data visualisation: monthly and daily consumption charts redesigned for legibility; colour-coded bands for high and low usage periods
Bill payment flow: streamlined from multiple screens to a clear 3-step confirmation with inline error handling

Clarity as the Product

Interface Redesign
A visual language built around what needed attention first: consistent enough to feel familiar to returning users, direct enough to need no explanation.
Accessibility
Built for the full range of the customer base, from digital-native users to people opening a utility app for the first time.
Data Legibility
Consumption and billing data translated into graphics that explain themselves: no manual required, no assumption of prior knowledge.
Service Consolidation
Billing, meter readings, loyalty, and activations: separate systems internally, one coherent flow for the person using the app.
Full UI spread: screen gallery showing home, meter reading, loyalty programme, and service activation flows side by side

Design Inside Someone Else's Constraints

The project was a lesson in designing around constraints that weren't design decisions: regulatory language, legacy billing systems, infrastructure that predated the app by decades. The job was translation as much as interface work.

What carried forward was a design system built to stay consistent with Enel's broader digital presence, so the next constraint wouldn't mean starting over.
