Easee, Zaptec and Octopus Charge become the first devices to carry the Mercury mark for smarter home energy

Easee has become the first Electric Vehicle Supply Equipment (EVSE) manufacturer to receive Mercury certification for grid flexibility services, marking a significant milestone for the company and for the wider effort to standardise how clean energy devices communicate with the grid.

The certification is awarded by the Mercury Consortium, an independent, non-profit industry initiative established by EPRI (Electric Power Research Institute) and Kraken Technologies to accelerate the adoption of interoperable clean energy technologies. Mercury certification confirms that Easee’s chargers meet independently verified requirements for grid-ready functionality, giving utilities, energy retailers and flexibility service providers additional assurance when selecting a trusted EV charging partner.

Often described as creating the ‘Bluetooth for energy’, Mercury certification solves a missing piece. Communication standards such as OCPP help connect devices. Mercury certifies how those devices behave once connected: whether they respond, report and perform in the way energy systems need.

Mercury develops practical technical guidelines and certification programmes that enable devices from different manufacturers, including EV chargers, heat pumps, residential batteries, smart thermostats and solar systems, to communicate reliably with utilities, aggregators and grid operators. Rather than creating new standards, Mercury focuses on interoperability and functionality, helping ensure that certified products can support demand flexibility services while maintaining consumer choice and future compatibility.

The consortium brings together utilities, grid operators, manufacturers, technology providers, regulators and research organisations from North America, Europe and Asia-Pacific. Its objectives include establishing technical interoperability guidelines, developing independent certification schemes, promoting consumer participation in demand flexibility programmes and supporting a more resilient, affordable and decarbonised energy system.

Easee has been an active participant in the Mercury Consortium since contributing to the development of its preliminary technical requirements for EV chargers. Achieving certification represents the next step in that relationship, positioning Easee as the first manufacturer to translate Mercury’s framework into certified, grid-ready products.

Anthony Fernandez, CEO of Easee, said: “Mercury certification provides global credibility and visibility, critical as Easee expands operations outside Europe. Mercury membership spans utilities, grid operators, technology providers and regulators across North America, Europe and Asia-Pacific, giving Easee access to an international market validation platform.”

“Consumers should not need to understand grid flexibility to know whether the device they buy is ready for the future,” said Devrim Celal, Co-Chair of the Mercury Consortium and Chief Flexibility and Marketing Officer at Kraken. “The Mercury mark is about making that trust simple. These first certified chargers prove that smart energy devices can be tested once, recognised by the market and used to unlock cheaper, cleaner energy for households.”

As demand flexibility becomes increasingly central to grid resilience, certification schemes such as Mercury are expected to play a growing role in how utilities and aggregators select charging partners. For Easee, this certification represents a clear market differentiator as the company begins to scale its presence beyond Europe.
