Renewable Energy Digit System - A new traceability system for ensuring local acceptance of green electricity offers

Volterres is able to provide its customers with a competitive and qualitative electricity supply offer at any time. This solution offers a traceability & monitoring system of the energy consumed, more accurate (time-lapse of 30 minutes) than conventional one-year certification, taking into account variations in the production of renewable energy.

To achieve this, Volterres developed an innovative traceability system called Renewable Energy Digit System ( R.E.D.S). R.E.D.S makes it possible to certify the geographical origin and the type of electricity actually consumed, offering consumers the background information to decide which renewable power plants will be the primary source of their electricity. By bringing to the fore independent renewable energy producers, this innovative solution strengthens the relationship between producers and electricity consumers while encouraging local authorities and independent energy producers to develop new local renewables projects.

Key features

  • Reduces the share of energy consumption from fossil sources by replacing it with local green sourcing, between 20 and 50% up until now

  • Contributes to the integration of renewable energies into the network, while limiting investments in management infrastructures for surplus


  • Same price than mainstream alternative
  • Immediate payback, the REDS solution is provided free of charge with the green and local electricity supply contract
  • Reduces the complexity of accessing locally produced green energy (compared to an onsite power plant or a traditional PPA): contract from 1 to 3 years vs 15 to 20 years
  • Reinforces the Corporate Social Responsibility of the consuming company by favouring local and environmentally friendly energy purchases, a competitive advantage for brands and corporations
