The Interoperability Challenge
Take a home EV charger, battery, heat pump, or solar inverter. Each one needs to talk to a grid operator or energy retailer, but there is no single standard for how.
Dozens of global protocols exist, there is no single standard. Dozens of global protocols exist, and which ones apply changes from country to country. So manufacturers and utilities fill the gaps with custom work, one connection at a time. And even where a shared standard is used, it leaves so much room for interpretation that no two devices end up speaking it the same way. A device proven with one utility starts again with the next.
Manufacturers lose engineering time to integration and rework instead of product. Retailers launch flexibility tariffs most of their customers' devices cannot join. Network operators reinforce substations that a controllable device fleet could have spared. Mercury solves this with a certification the device earns once, ensuring interoperability with every Mercury-aligned utility and platform.
