Go Distributed

Procure clean energy in the places, times and communities that are important to your business

This Bay Area startup will help steer billions of dollars towards clean energy investments.

A new way to buy clean energy

WattCarbon aggregates distributed energy resources nationwide to provide organizations with a flexible and high impact way to buy clean energy and meet their goals.

Distributed clean energy enables procurement of any volume, in any market, with projects that are shovel ready, driving immediate impacts for our climate and our communities.

A satellite image of an urban landscape, with 75 distributed energy resource projects marked on buildings across the landscape. The projects come from a vPPA for energy from batteries that was purchased on August 1st, 2023. Since October 1st, 2023, the vPPA has produced 381.0 Megawatt-hours of energy.

EACs help you maximize impact

An Energy Attribute Certificate (EAC) is a granular certificate that shows every attribute of clean energy, generated by the watt-hour. EACs provide far more transparency than traditional RECs, and enable targeted procurement so you can buy based on the impacts you need, with complete confidence in your clean energy claims.

Mockup of an energy attribute certificate. The amount is 1 kilowatt-hour. The energy resource is Battery. The dispatch date is January 1st, 2024. The dispatch time is 7PM. The location is Texas, with coordinates 32.80 North 97.60 West.  . The operation start date is December 1, 2023. The utility is Oncor. The balancing authority is ERCOT. The emissions intensity is 408.9 kilograms CO2 per Megawatt-hour. Other attributes are Low/Moderate Income Community.

Buying clean energy with EACs

Because the energy grid carries a mixture of energy generated from clean and dirty energy sources, energy buyers can't receive only the clean electrons. Energy Attribute Certificates (EACs) give energy buyers a unique claim to the electrons on the grid that are generated from clean energy sources.

Monetize your carbon impacts

The WattCarbon Energy Attribute Tracking System (WEATS) values and tracks emission reductions from all forms of energy decarbonization. Add your distributed energy generators, create EACs, and sell them on our marketplace.

Report with confidence and granular transparency

WattCarbon is powered by open-source measurement & verification and a 24/7 EAC registry that tracks impact to each gram of CO2e and watt-hour. Have confidence your procurement is free from double counting, compliant with reporting frameworks, and future-proofed in anticipation of increased rigor and scrutiny.
