What WattCarbon does
WattCarbon is a San Francisco-based data infrastructure platform founded in 2021 that provides automated measurement, verification, and certification of energy savings from distributed energy resources (DERs). Its core products include the Aristotle M&V engine, which ingests utility AMI data, sub-meter telemetry, and device signals to produce hourly verified energy and carbon savings; the WEATS registry, which issues serialized hourly Energy Attribute Certificates (EACs) with ownership tracking, transfer, retirement, and double-counting prevention; and the GridScore and CarbonScore metrics, which quantify capacity value during grid peaks and kilograms of CO2 avoided per MWh, respectively. Program modules address specific use cases including DER programs, Virtual Power Plant dispatch verification, performance contracting, EAC marketplaces, and community energy, supported by an OpenAPI-compliant REST API for partner integration.
The company serves three primary customer segments: utilities and Community Choice Aggregators needing independent verification of DER-delivered savings; large energy consumers (data centers, corporate campuses, industrial) requiring credible proof of local clean energy impact for sustainability claims; and energy service providers, DER developers, and aggregators seeking portable, third-party-verified performance records for financing and market participation. WattCarbon monetizes through capacity-based subscriptions ($0.20/kW/month for Aristotle, $0.15/kW/month for WEATS, $0.30/kW/month combined) with a free entry tier launched in October 2025, supplemented by custom Program Administration contracts for multi-participant programs. The company has raised approximately $6M across pre-seed (December 2021), seed (January 2023), and an undisclosed seed extension (July 2025), operates with 1–10 employees, and counts Siemens, Prologis, Rewiring America, NYSERDA, and BayREN among its named customers and partners.

Revenue model
- Aristotle M&V Platform Subscription: Capacity-based subscription pricing ($0.20/kW/month) for measurement and verification services. Pricing based on registered capacity (kW) of enrolled assets, not on savings or performance outcomes. Keeps costs predictable and directly tied to asset scale. Provides verified hourly performance data, GridScore and CarbonScore, custom M&V plans, and full API access.
- WEATS Registry Certification: Capacity-based subscription pricing ($0.15/kW/month) for Energy Attribute Certificate issuance and registry services. Includes hourly EAC issuance with unique serial numbers, ownership tracking and transfer, retirement, and double-counting prevention.
- Combined Aristotle + WEATS: Combined pricing at $0.30/kW/month for using both Aristotle and WEATS on the same asset. Each asset can have a different combination of features.
- Program Administration: Custom contract pricing for organizations running programs with multiple participants - developers, offtakers, regulators. Includes Program Admin UI, configuration engine, stakeholder management, SLA guarantees, team training, and priority escalation. All premium features included.

WattCarbon product offering
Product offeringCore offering
WattCarbon operates a data infrastructure platform for demand-side energy resources, providing automated measurement and verification (M&V) of distributed energy assets. Its Aristotle engine ingests utility AMI, sub-meter, and device telemetry data to compute hourly energy savings, capacity value, and carbon impact, while its WEATS registry issues uniquely serialized hourly Energy Attribute Certificates (EACs) with ownership tracking and double-counting prevention for utilities, ESCOs, DER developers, and large energy consumers.
Product overview
WattCarbon offers a modular data infrastructure platform for demand-side energy resources. The core platform consists of Aristotle (automated M&V engine) and WEATS (Energy Attribute Certificate registry), supplemented by GridScore and CarbonScore for capacity and carbon impact scoring. Program modules including DER Programs, VPP Dispatch Verification, Performance Contracting, EAC Marketplace, and Community Energy provide use-case-specific implementations. An OpenAPI-compliant REST API enables building integrations, while the WattCarbon Finance Platform supports project financing transactions. GridSolver provides grid optimization analysis capabilities.

WattCarbon competitors and assessment
Company assessmentDirect peers
- Uplight: Uplight is an energy customer engagement and analytics platform that helps utilities run energy efficiency, demand response, and DER programs with verified outcome data. Most directly comparable to WattCarbon because it serves the same utility buyer for DER program M&V and program administration, though Uplight has a much broader feature surface (billing, CRM, marketplace).
- EnergyHub: EnergyHub is a DER management platform used by utilities and aggregators to manage demand response, distributed energy storage, EVs, and smart thermostats. Comparable to WattCarbon's VPP dispatch verification and DER aggregation modules; both serve utility program operators seeking to manage and verify distributed asset performance.
- Recurve: Recurve provides an open-source measurement and verification platform for energy efficiency programs, with a strong focus on California and utility program administrators. Highly comparable to WattCarbon's Aristotle M&V engine because both use statistical baseline modeling to produce verifiable savings — Recurve is the closest direct competitor on M&V methodology and customer base.
- Arcadia: Arcadia operates a clean energy data platform connecting utilities, enterprises, and renewable generators, with REC/carbon accounting and a marketplace for energy attributes. Comparable to WattCarbon's WEATS registry and CarbonScore on the EAC issuance and carbon-tracking side, though Arcadia focuses more on annual RECs than hourly 24/7 matching.
- Leap: Leap is a DER marketplace and procurement platform that connects distributed energy developers with utilities and large buyers. Comparable to WattCarbon's EAC Marketplace and Performance Contracting modules on the transactional side; both operate in the demand-side energy procurement infrastructure layer for utilities and hyperscalers.
- Piclo Energy: Piclo Energy operates flexible energy marketplace platforms that match renewable generators and community energy with buyers (already a WattCarbon partner for Community Energy/ACE initiatives). Comparable because both run marketplace infrastructure for matching energy supply and demand with verified attributes.
- ClearTrace: ClearTrace is a carbon and energy attribute tracking platform for enterprises, utilities, and project developers, with a focus on 24/7 hourly carbon matching. Direct overlap with WattCarbon's WEATS registry and CarbonScore on hourly EAC issuance and carbon accounting for corporate buyers.
- CPower: CPower is a demand response and virtual power plant aggregator that helps commercial and industrial customers monetize load flexibility and provides dispatch verification for utilities and grid operators. Comparable to WattCarbon's VPP dispatch verification module on the demand response side, though CPower is more of an aggregator than a verifier.
Emerging players
- Kevala: Kevala provides energy data analytics for grid planning, DER siting, and interconnection analysis, primarily serving utilities and regulators. Partial overlap with WattCarbon on energy data analytics infrastructure for utilities, but focused on planning rather than post-deployment M&V and certification.
- WattTime: WattTime provides real-time and historical grid emissions data and monitoring (MOER, AVERT) used by utilities, developers, and corporate buyers to attribute carbon impact to electricity use. Methodologically adjacent to WattCarbon's CarbonScore (marginal/average emissions rate calculations) but focused on data rather than registry and M&V.
