BACKGROUND

Ebitts is an innovative digital platform by Enel that enables users to access renewable energy production without installing physical systems at home. It’s designed for those who can’t install solar panels but still want to contribute to the energy transition and save on their electricity bills.

Using blockchain technology, Ebitts allows users to purchase “tokens”—virtual shares of real wind and solar plants located in Italy. This system turns users into “virtual prosumers,” letting them benefit from renewable energy without owning or installing equipment.

The Token Box is the product users buy through Ebitts. It consists of a mix of tokens representing virtualized portions of actual plants. Once activated, the energy produced by a Token Box is automatically deducted from the metered consumption, reducing the amount billed. The energy produced can be tracked through an app.

CURRENT SITUATION

Since the Token Box is a virtual product, its value and impact may not be immediately tangible. Therefore, the challenge is to design a physical, digital, or phygital element that bridges the gap between the virtual and real worlds. This element should make the experience more engaging, clear, and concrete—enhancing user understanding and emotional connection to the project.

The goal is to strengthen the perceived value and benefits of Ebitts. The development of the proposal should enhance the user's perception of the energy generated by the plants linked to their tokens, making the concept of production more tangible and translating it into a concrete benefit: savings on their energy bill. Alongside this direct value, additional benefits related to sustainability and energy transition emerge, turning an abstract concept into a clear, concrete, and rewarding experience.

LIMITATIONS OF EXISTING SOLUTIONS: THE NEED FOR INNOVATION

Unlike traditional services or energy offers, the Token Box is not a subscription-based product (such as Netflix or Spotify, which can be stopped at any time) and not an energy supply contract offering renewable electricity from the market. Instead, it represents a virtual yet tangible product, linked to the real production of renewable energy plants.

Each token corresponds to a specific, verifiable share of renewable energy production, representing a digital ownership of that production capacity. For the user, owning a Token Box is almost equivalent to owning a physical photovoltaic panel or a small wind turbine, even though such device does not exist at a domestic scale. However, since the Token Box remains a virtual asset, it is essential to create a bridge that makes its value and functioning more tangible and comprehensible to users — helping them clearly perceive the connection between their tokens and the real energy being produced.

THE CHALLENGE

The challenge aims to find a physical, digital or ‘phygital’ innovative concept design  for users that connects the virtual and real world and clearly communicates the perception of owning a virtual energy production plant, symbolically reflecting the amount of energy produced.

For all types of solutions (digital, phygital, or physical), it is necessary to consider potential scalability

up to >10,000 users.

The proposal should address the following needs:

Must Have:

For all type of innovative solutions (physical, digital or ‘phygital’) is required an intuitive "interface” to create a bridge between virtual and real that makes Ebitts  value and functioning more tangible and comprehensible to users that displays:

•Representation of user’s ownership  – the solution must clearly show that the tokens are equivalent to digital user ownership of renewable energy production (e.g., a virtual share of a plant).In attached Annex 2 Ebitts functionality presentation

• Evidence of Real-time production – Users must be able to view the actual renewable energy production associated with their tokens.

ü Enel’s brand application in accordance with the guidelines given in Annex 1

ü Scalability: Solution easy to adopt for up to >10,000 users with affordable cost.

ü Innovation and creativity level of the solution

Nice to Have:

For all type of solutions ( physical, digital or ‘phygital’)

ü Social sharing – Possibility to share achievements, energy contribution, or environmental impact on social platforms.

ü Dynamic rewards (gamification) – Incentives linked to energy auto-consumption.

ü  Sustainability and circularity of the solution

DELIVERABLES

A presentation in which find , for all type of innovative solutions ( physical, digital or ‘phygital’ ) the following required delivarebles:

MUST HAVE:

✔ A Descriptive presentation of the concept design of solution with clear evidence  of the development of must have criteria .This should comprise a clear estimation of an assessment of technical feasibility and executability with development effort or production costs, and implementation phases, and, where applicable, a forecast of the expected useful life and maintenance requirements of the solution.

✔ Graphics and/or 3D Drawings, including renderings, and views to understand functionality and user interaction.

o  If the product is digital, visuals may include UI mockups, wireframes, or prototypes created in tools such as Figma.

o  If the product is physical, it should be include 3D drawings or CAD models that show form, structure, and usability details.

ü Emotional or functional video, maximum duration 1 minute.
