Flexidao: sovereignty score and 8 European alternatives

Flexidao is a Spanish software platform and operational service for organisations that buy clean electricity. It tracks renewable energy certificates, monitors the performance of virtual power purchase agreements (VPPAs) and provides granular Scope 2 emissions accounting on a market basis. Large companies with portfolios across several regions use it to combine billing, meter and certificate data. The service is offered as an online application that Flexidao operates on behalf of its clients.

Flexidao S.E.S. S.L.U. is based in Barcelona and describes itself as ISO 27001:2022 accredited. The company's website does not describe its ownership, and no majority shareholder is named. Flexidao does not publish where customer data is stored or which sub-processors it uses; its privacy notice refers those enquiries to its security team. A European organisation should therefore request the hosting location and sub-processor list in writing before signing a contract.

Why digital sovereignty matters with Flexidao

Flexidao is headquartered in ES and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Flexidao scores best on data residency.

Flexidao is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Flexidao together with your other vendors and gives a total score, a heatmap and the main risk drivers.
