Charging networks are scaling faster than the software foundations supporting them.
OCPP 2.0.1 enabled early deployments, but rising energy costs, diverse hardware, and stricter security now demand more—OCPP 2.1 delivers, and S44 Energy is already deploying it.

How S44 Energy Helps

S44 Energy is uniquely positioned to implement OCPP 2.1 because we:

• Are the original authors of CitrineOS Confidently work with the authors of CitrineOS, no guesswork or handoffs.
• Actively extend CitrineOS with OCPP 2.1 Run multiple solutions simultaneously while extending protocol support with CitrineOS.
• Deploy OCPP upgrades in production Achieve both OCPP 2.0.1 + OCPP 2.1 with one proven foundation.
• Build compliant custom extensions Move fast while staying standards-aligned for long-term interoperability.
