What The Dillinger Group does
The Dillinger Group is a fully integrated renewable energy developer and operator headquartered in Regensburg, Germany, specializing in large-scale photovoltaic plants, industrial energy storage, and EV charging infrastructure. The company develops, plans, constructs, and operates renewable energy facilities through three wholly-owned subsidiaries: DG ENERGY Solutions GmbH serves as the in-house EPC contractor, DG ENERGY Service GmbH provides O&M and asset management across the German portfolio (achieving 99.3% plant availability), and DG ENERGIE Italia s.r.l. manages the Italian operations. The company has accumulated over 17 years of experience since its founding around 2007, and operates across Germany, Italy, and Spain. It serves enterprise logistics customers (including ARS Altmann AG), landowners with degraded or underutilized sites, industrial operators, and agricultural businesses seeking agrivoltaic solutions.
The company's technology portfolio includes ground-mounted PV plants, single-axis tracker systems with a proprietary control system co-developed with isa industrieelektronik GmbH (delivering a 40% production uplift at the Melpignano plant), PV carports (the company ranks 3rd and 5th globally for largest carport installations at Lonato 21.71 MWp and Riedstadt 17.5 MWp), agrivoltaic installations, industrial rooftop PV, battery energy storage, and self-constructed high-voltage transformer substations (63 MVA and 100 MVA units) that connect directly to the transmission grid without reliance on external utility infrastructure. Cumulative operational and under-construction capacity exceeds 164 MWp across Germany and Italy, with the Schlön plant in Mecklenburg-Vorpommern (60+ MWp, operational January 2026) as the largest single asset.
The business model combines multiple revenue streams: one-time project development and sale, turnkey EPC services through DG ENERGY Solutions, recurring O&M and asset management contracts (both for owned and third-party assets), and long-term Power Purchase Agreements (PPAs) that deliver multi-year recurring revenue from direct electricity marketing to local consumers. The company also provides M&A advisory services for small and medium-sized renewable energy businesses facing succession challenges. Pricing is project-by-project and quote-based, with long sales cycles typical of B2B enterprise infrastructure. Customer segments are split horizontally across logistics and industrial enterprises (primary), commercial, industrial, and agricultural landowners (primary), agricultural operations for agrivoltaic projects (secondary), and SME owners in renewable energy for M&A advisory (secondary).

Revenue model
- Renewable Energy Plant Development & Sale: The Dillinger Group develops PV projects from inception through to operational readiness, including site acquisition, permitting, EPC execution, and commissioning. Projects are either sold to investors/operators after development and construction (with due diligence advisory), or retained in the company's own asset portfolio for long-term operation and energy sales.
- Engineering, Procurement & Construction (EPC): Through the affiliated company DG ENERGY Solutions GmbH, The Dillinger Group provides turnkey construction of PV plants, charging infrastructure, and storage systems. EPC services are delivered with over 17 years of experience and cover the full project lifecycle from planning to component selection and commissioning.
- Operation, Maintenance & Asset Management: DG ENERGY Service GmbH provides full-service O&M and asset management for all Dillinger Group plants across Germany and Italy (via DG ENERGY Italia s.r.l.), achieving a 99.3% availability level across the managed portfolio. This generates recurring service revenue from owned and third-party assets.
- Power Purchase Agreements (PPAs): The company negotiates and concludes long-term electricity supply agreements (PPAs) with energy consumers, enabling direct marketing of locally produced electricity. This creates recurring revenue streams from energy sales at stable, pre-agreed prices over multi-year terms.
- M&A Advisory: The company provides M&A advisory services for the acquisition of small and medium-sized renewable energy companies, leveraging 17 years of industry experience. This includes consulting for integration into The Dillinger Group or negotiations with other partners.
