Electric power generation, transmission and distribution

The buyer is a regulated utility that procures by RFP on a five-to-ten-year cycle with rate-case scrutiny of every dollar, so the sales cycle is measured in years and the reference list is the product. Itron's $2.4B is mostly devices and outcomes rather than CIS licences, which says where the money actually is: in the meter, not the software. Adjacent to the grid-interconnection study at 221121, which reached the opposite verdict on a narrower wedge.

Renewable-project software is not one market but four layers, and every layer already has a funded owner. The customer is the solar, wind and storage developer or independent power producer (this NAICS); the residential and commercial design layer also sells to solar installers, who sit in 238220/238210. Installer design and proposal is owned by Aurora Solar. Aurora raised a $250M Series C led by Coatue in May 2021 at a $2B valuation and a $200M Series D co-led by Coatue and Energize Ventures in February 2022 — more than $520M in total [B: Canary Media; Aurora's own release] — and bought HelioScope's developer Folsom Labs for the commercial tier in 2021 [B]. The challenge comes from two directions a newcomer cannot copy cheaply: OpenSolar gives the software away (free to installers, earning from finance and partners; US$20M from Titanium Ventures and Google in October 2025, 28,000+ pros claimed) [B; C], and Enphase owns Solargraf, using it to pull installers toward its hardware [B]. Enerflo sits beside them as the sales-and-install operating system for residential solar sales organisations [C]. Utility-scale design has consolidated. PVcase took a $100M Series B in 2023 (Highland Europe, Energize) [B]; RatedPower went to Enverus in 2022 [B]; Terabase raised $130M led by SoftBank in March 2025 ($200M total) to tie design (PlantPredict) to construction software and robotic assembly [B]. Operations and asset management is the most locked-in layer and the most concentrated. Power Factors has been Vista-owned since 2021, rolled up Greenbyte and 3megawatt, and says it now covers 310 GW; Mubadala bought a minority stake in May 2026 [B]. Raptor Maps ($35M Series C, December 2024) owns drone inspection and the solar digital twin [B], with Zeitview and SenseHawk alongside. Development, diligence and finance workflow is the open layer — and it is filling. Euclid raised a $20M Series A led by Venrock in September 2025 and claims 12 GW onboarded [B; C]; Odyssey raised $74M of equity and debt in September 2026 for emerging-market distributed solar, where it is the platform Nigeria's DARES programme mandates [B]; Paces sells siting and permitting data; Frigg matches small projects with investors on grant-stage funding [C]. Incumbent vulnerability decides it. The installer tier has a $520M-funded leader under price attack from a free product and a hardware maker; utility-scale design and asset management are owned by a SoftBank-, Highland- and Vista-backed set; and the development-workflow gap that looked open in 2023 now has Venrock and development-finance money in it. Market size and vendor revenue UNVERIFIED — every vendor is private or inside a parent. How this differs from its neighbours: 221121 (grid interconnection and large-load power) is queue and site intelligence sold to data-centre and large-load developers, where Enverus/Pearl Street lead; 2211 covers utility metering, billing and customer systems; the 541620 records cover carbon, ESG and efficiency reporting. This record is the project software that designs, sells, builds, finances and operates the generating asset itself.
