Elia Group launches re.alto, its own corporate start-up to accelerate digitalisation of the energy sector


  • First European marketplace for the exchange of energy data via standardised energy APIs
  • re.alto brings together data providers and data consumers from all sides of the energy economy
  • re.alto reduces the cost of data acquisition and accelerates the digital transformation of the energy industry


BRUSSELS – BERLIN | Elia Group has today officially announced re.alto, its first corporate start-up company. The re.alto marketplace brings together providers and users from all sides of the energy economy. The aim of the re.alto marketplace is to make energy data easy to access and integrate, enabling the industry to take a giant digital stride towards more widespread adoption of Energy-as-a-Service business models and ultimately drive a low carbon energy future.

The re.alto marketplace, launched to market in recent months, has already attracted significant interest from companies across the energy value chain. For organisations with data and digital products to offer, the platform provides a new sales channel to monetise their APIs (Application Programming Interfaces) to new markets, generating new revenue stream opportunities. For businesses who want to buy and integrate third-party data, the marketplace offers simple access to a range of digital tools to streamline the API exchange process and bring down the cost of data acquisition, which previously may have been prohibitively expensive.

A European first

re.alto is the first European marketplace for the exchange of energy data, digital products and services via standardised energy APIs. The marketplace already features a wide range of energy-related API products from industry-leading providers who are consistently pushing the boundaries of digital innovation in sectors such as e-mobility, utilities, and market intelligence. Example use-cases for APIs currently on the platform include spot market pricing, forward market pricing, energy monitoring, smart charging for electric vehicles, smart meter data, wind SCADA data, energy communities and boost charging-as-a-service.

Harnessing the power of external data should be a key objective in any digital strategy of an energy company looking to scale. Data connectivity enables innovation on a level previously unachievable in energy as well as the creation of new customer-centric business models. It is a powerful driver of growth in a sustainable energy sector.

To support the announcement and shine a light on how the exchange of energy data can accelerate digital transformation and decarbonisation, re.alto has published a whitepaper titled Realising the energy transition in times of change: the role of the API marketplace in driving down data acquisition costs and establishing new service-led business models.”

The whitepaper explores the barriers to digital change faced by the energy industry, particularly focussing on the exchange of energy data, a crucial cornerstone of digitalisation.  It looks at the opportunities for innovation presented by the dual crises of Covid-19 and climate change, highlighting the valuable role that an API marketplace can play in enabling operational streamlining and the creation of entirely new revenue streams.
