The clean energy transition, at the utility scale, is an accounting problem. It’s not just about building more solar panels. It’s about proving, to the minute, which electron came from where, who gets to claim it, and what certificate of cleanliness gets stapled to its virtual passport. For a utility running a green tariff program, this is a spreadsheet nightmare that quickly scales into a full-time department. Singularity Energy, a software company out of Somerville, Massachusetts, sells a system to make that nightmare go away. They are building the ledger for the hourly grid.
Founded in 2018 by Wenbo Shi, a postdoctoral researcher studying clean grid operations, Singularity started with a focus on real-time carbon data [Singularity Energy]. Its Carbonara product provides granular, location-specific emissions estimates for the grid, blending public data with proprietary insights from partners like Eversource [Singularity Energy]. But the company’s bigger bet is on the operational layer above the data: the software that utilities use to actually run their clean energy programs, from tracking Renewable Energy Credit (REC) inventory to allocating Energy Attribute Certificates (EACs) and handling compliance reporting [Singularity Energy].
The bet on hourly matching
The wedge is a regulatory and commercial shift toward hourly, rather than annual, matching of clean energy supply to customer demand. Corporations with 24/7 carbon-free energy goals don’t just want to buy enough renewables over a year; they want to know their power was clean at 3 a.m. on a Tuesday. This creates a massive data-tracking and allocation challenge for the utilities serving them. Singularity’s platform aims to connect generation data, program operations, and reporting obligations into a single system, automating what is often a manual, error-prone process [Singularity Energy]. As one utility partner described it, the platform matches generation to consumption "based on contractual relationships and allocation rules for an hourly accounting framework" [Southern Company].
From pilot to production with Southern Company
The most concrete signal of traction is the journey with Southern Company subsidiary Georgia Power. In 2024, Southern Company began a six-month pilot of Singularity’s solution focused on a subset of 10 commercial and industrial customers [Southern Company]. By July 2026, Georgia Power had expanded the platform from that pilot to production across its C&I renewable program customers [Singularity Energy]. This is the classic enterprise SaaS playbook in action: land a pilot with a segment of a giant’s business, prove the value, and expand to the entire operation. For a utility, moving a critical compliance function from pilot to production is a significant vote of confidence.
The team and the backing
Shi has built a team with roots in power systems research from institutions like Harvard, MIT, and Johns Hopkins, according to company materials [Medium]. The company is also a member of Greentown Labs, the cleantech incubator [Greentown Labs]. On the capital side, Singularity has raised at least $4.5 million, according to a May 2022 report, with backing from a mix of climate-tech and generalist funds including Analog Ventures, Spero Ventures, Third Sphere, and the utility-focused Energy Impact Partners [Tech Startups]. The investor mix suggests a bet on both the software opportunity and the specific dynamics of the regulated utility market.
The competitive landscape is populated by consultants, data providers, and specialized software firms. A look at the key players shows where Singularity is trying to carve out its space.
| Competitor | Primary Focus | Singularity's Angle |
|---|---|---|
| REsurety, WattTime, Tomorrow | Carbon data & analytics | Bundling operational software with its Carbonara data layer. |
| The Brattle Group, Energy and Environmental Economics (E3) | Consulting & modeling | Offering a software product to automate what consultants often manually analyze. |
| Intelligent Generation, Enspi.io | DER & program management | A sharper focus on the REC/EAC accounting and compliance reporting workflow for utility programs. |
Where the wheels could come off
The path is not without its bumps. Utilities are famously slow-moving customers with long sales cycles and deep institutional caution. Singularity’s success with Georgia Power is promising, but one production deployment does not guarantee a wave of followers. Furthermore, the company’s headcount is reported with frustrating inconsistency across databases, ranging from 6 to "11-50" employees [PitchBook] [Wellfound] [LeadIQ] [SignalHire]. This kind of data noise often surrounds small, private companies, but it underscores that Singularity is still in the early stages of scaling its own operations alongside its software.
The company’s answer likely lies in the specificity of its product and the inevitability of the hourly-matching trend. By solving a painful, compliance-heavy workflow for a specific buyer (the utility program manager), they avoid being a generic data dashboard. Their published work, like a white paper on clean energy market boundaries prepared for Google, also positions them as serious technical contributors to the policy conversation, not just vendors [Singularity Energy].
The unit economics of clean electrons
The value of this software, in the end, is measured in avoided cost and risk. Consider a utility with 1,000 C&I customers on a green tariff. Manually reconciling hourly generation with consumption across a year involves 8,760 hours of data per customer, or 8.76 million data points to track and certify. A single full-time employee might manage the process for 50 customers before drowning. The back-of-the-envelope math is simple: if the software saves two full-time program managers earning $150,000 each in salary and overhead, it pays for itself at an annual contract value of $300,000. For a major utility, that’s a rounding error compared to the regulatory and reputational risk of a compliance error.
Singularity Energy is not trying to beat the flashy carbon data startups on the freshness of their grid emissions map. It is trying to beat the sprawling, expensive spreadsheets maintained by armies of analysts at firms like The Brattle Group. Its bet is that utilities would rather buy a certified system than continue to build and audit a fragile one in-house. For now, with a key utility moving from pilot to production, that bet is starting to look like more than just clean data. It’s starting to look like a business.
