Market Context

Flexibility is the new grid capacity.

Electrification is accelerating, but grids cannot scale affordably. Utilities are turning to flexible, smart energy devices in homes and businesses to balance demand, avoid excessive infrastructure spend, and unlock renewable adoption.

Grid Strain

EV chargers, heat pumps, and batteries are multiplying faster than the grid can expand.

Regulatory Shift

Regulations and standards like Clean Flexibility Roadmap, PAS 1878 and Mercury are driving devices towards grid readiness from 2027.

Integration Sprawl

Flexibility providers must build multiple point-to-point integrations, this does not scale.

Our Vision

A universal stack for energy devices.

WattStack connects devices, OEMs, and flex providers through open standards to deliver modular, secure, compliant, and reliable connectivity at scale.

Today

Costly proprietary communication stacks and APIs prevail, flex providers must maintain dozens of bespoke integrations.

Result

High costs, inconsistent functionality, and a widening security risk surface across the grid.

WattStack offers something new: an open, modular, standards-native stack with no lock-in risk.
