Granular certificate infrastructure

Measurement & verification that proves actual energy impacts

End-to-end auditability that links every EAC to a real-world project and certifies the associated time and locational energy savings.

One-click data integrations

Use the data that you already collect to start tracking your demand-side energy assets today. Just connect and go; it's really that easy.

Granular certificate tracking

An EAC is the atomic unit of the energy transition, representing one watt-hour of energy value. Each EAC tracked by WattCarbon receives a unique serial number in WEATS, which prevents double counting and allows demand-side energy resources to be transacted between third parties.

Open standards, verified impact

WattCarbon is a founding member of the OpenEAC Alliance. The Alliance is an industry group of measurement & verification professionals that review and approve methodologies used to calculate demand-side energy savings.

A new registry for clean energy credits could boost the grid value of DERs

Read Article
We wanted to build a system of record that would allow DERs to participate on an equal footing with traditional wind and solar so that we can help tap into those resources as part of a transition to a 100% carbon-free grid.
