Flexisun®: an integrated offer that combines solar potential and energy storage. ENGIE has developed Flexisun so that solar energy generated on-site can also be consumed when the sun is not shining. This solution maximises self-consumption of decarbonised and local energy, on average 20% higher than a photovoltaic installation alone, further reduces CO2 emissions and electricity bills, and increases energy self-sufficiency and resilience regarding the grid. Thanks to Flexisun®, it is also possible to take advantage of other local renewable sources, or integrate charging stations for electric vehicles, improve the quality and reliability of electricity supply, benefit from the additional advantages offered by the battery: optimised prices, reduced consumption peaks, participate in grid ancillary services, etc. Finally, the Energy Management System (EMS) allows to control the installation in real time and to optimise the different components. With Flexisun®, ENGIE is helping its customers, business, and local authorities to make the transition to carbon-neutral energy with a combination of onsite renewable energy, with storage and an energy management system.

The Environmental Benefits

  • Maximize green onsite self-consumption for On-grid configuration (40 to 80%)
  • Reduce fossil fuel consumption for Off-grid configuration (60 to 90% fuel savings)
  • Increase energy autonomy and resilience
  • An industrial client with a load of 3 GWh/year can avoid 2900 T of CO2 over 10 years
  • For an island project, over 6000 T/year of CO2 can be avoided through the reduction of diesel consumption

The Financial Benefits

  • FLEXISUN allows to reduce electricity bills by 10% or more in the long term
  • FLEXISUN allows to avoid voltage dip interruptions by up to 100 K€ per year
  • A fully financed solution that enables clients dedicate their own CAPEX to their core business
