What node.energy does

node.energy GmbH, founded in 2016 in Frankfurt, Germany, operates the opti.node SaaS platform for the regulatory and commercial management of decentralized renewable energy assets in the German market. The platform centralizes energy data, automates electricity tax (Stromsteuer) filings, handles § 6 EEG municipal participation calculations, performs EDIFACT-based market communication across BDEW/DVGW-coded roles (Supplier, Balance Responsible Party, Dispatch Responsible Party, Technical Resource Operator, Energy Service Provider), and provides revenue monitoring for direct marketing and EEG feed-in tariff income. As of April 2025, the platform managed more than 14,000 wind and solar plants, up from roughly 10,000 in mid-2022, and supports enterprise customers such as Sabowind, CTP, VGP Germany, Schrott Wetzel, Geis Group, Münzing Chemie, DenkerWulf, Sunrock, and SAB WindTeam.

The core product surface consists of interconnected modules — Commercial Operations Management (Kaufmännische Betriebsführung), Electricity Tax Reporting, § 6 EEG Municipal Participation, Revenue Monitoring, and Tenant Electricity / Onsite PPAs — accessed through the opti.node Cockpit interface launched in March 2026. The company has built proprietary database technology for energy-industry data scale and traceability, and holds BDEW/DVGW code numbers enabling it to act directly in German energy market communication. Distribution is direct enterprise field sales, with dedicated sales leads covering digital operations, wind and solar parks, and tenant electricity, supplemented by a 2025 channel partnership with metergrid for the Mieterstrom segment.

node.energy is venture-backed, having raised approximately $24.6M in total funding: a €7M Series A in July 2022 led by BitStone Capital, and a €15M Series B in April 2025 led by DTCF (Deep Tech & Climate Fonds) and eCAPITAL entrepreneurial Partners with participation from Redstone VC. Headcount stood at 96 employees as of December 2025. The company monetizes through subscription-based SaaS contracts with annual billing cadence, pricing is quote-based and not publicly disclosed, and the operating geography is concentrated in Germany.

Core offering

node.energy develops opti.node, a cloud-based SaaS platform for commercial asset management of renewable energy plants. The platform centralizes energy data, automates billing and regulatory compliance (electricity tax, municipal participation under § 6 EEG, revenue monitoring), and handles market communication (EDIFACT) for wind and solar park operators and commercial/industrial energy buyers in Germany.

Product overview

node.energy offers opti.node, a unified SaaS platform for commercial operations management of renewable energy assets. The platform combines multiple functional modules: commercial operations management (Kaufmännische Betriebsführung), electricity tax reporting, municipal participation under § 6 EEG, revenue monitoring, and tenant electricity/onsite PPA solutions. All modules share a common data layer and are accessible through the opti.node Cockpit interface, enabling wind and solar park operators to centralize energy data, automate regulatory compliance workflows, and streamline billing and administrative tasks.

Scale indicators7 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Kiwigrid GmbH: German IoT/energy management SaaS connecting distributed energy assets (PV, battery, EV) for utilities and C&I customers. Comparable in serving renewable and decentralized energy management with software, though oriented to device/IoT connectivity versus node.energy's commercial/regulatory focus.
• envelio: Cologne-based SaaS for grid operators and energy transition use cases (Integration Suite, grid planning). Comparable as a venture-backed German energy-software peer, though focused on grid/distribution rather than renewable commercial asset management.
• Ampeers Energy GmbH: German SaaS provider of district energy and virtual power plant management software. Comparable as a venture-backed software player in the renewable/decentralized energy space; product manager on node.energy's team previously worked here.
• Enerix GmbH: German franchise network for decentralized solar/PV and storage, plus tenant electricity and PPA offerings. Comparable as a customer/partner archetype for node.energy's tenant electricity and onsite PPA modules in commercial real estate.

Broad incumbents

• Smart Energy Solutions GmbH (Lichtblick/SEEL): One of Germany's largest independent green electricity and virtual power plant operators. Comparable end-market (renewable energy commercial operations, EEG framework) though broader scope and incumbent scale rather than pure software.
• BayWa r.e. (Energy Solutions): Large global renewable energy developer/operator with operations in Germany. Listed as a customer logo on node.energy's site; comparable as a large German renewable asset operator that could either adopt opti.node or compete as an in-house alternative.

Direct peers

• Next Kraftwerke: German VPP operator and direct marketer of renewable energy. Comparable because it sits at the intersection of renewable energy commercial operations, market communication, and software-driven asset management for distributed wind/solar/biogas plants — overlapping with node.energy's regulatory and trading infrastructure.
• Powercloud GmbH: Cloud-native SaaS for utility billing, energy data management, and market communication in Germany. Closely comparable as a SaaS provider handling EDIFACT-based market processes and German regulatory compliance for energy suppliers and operators.
• Soptim AG: German software vendor offering commercial asset management and billing solutions for utilities and renewable energy operators, with EDIFACT market communication capabilities. Directly comparable product footprint to opti.node for German RE operators.
• Clean Energy Sourcing AG (CLENS): Co-founded by node.energy's CEO Matthias Karger; one of Germany's first direct marketers of renewable energy. Operates in the same EEG-driven direct marketing and commercial asset management space that node.energy's opti.node platform serves.
