Saxovent Renewables and HIH Real Estate Combine Expertise to Develop Sustainable Energy Solutions for Real Estate Portfolios

Partnership to sustainably harness energy potential in real estate portfolios

Berlin, September 11, 2026 – Saxovent Renewables GmbH & Co. KG and HIH Real Estate GmbH are combining their expertise to expand the use of renewable energy in real estate portfolios. Together, they will analyze, develop, and implement sustainable energy solutions on suitable existing properties.

The partnership will identify untapped potential in existing properties and use it to develop energy solutions that remain economically viable over the long term. In particular, the partners will examine roof areas and existing infrastructure to determine how renewable energy generation can best be integrated into current real estate strategies.

The partners approach each property’s energy needs comprehensively: In addition to conventional photovoltaic solutions, they assess further options for energy supply and optimization based on the specific site. By making the best possible use of available space, they aim to make properties both environmentally and economically sustainable over the long term.

As requirements for energy efficiency, ESG criteria and security of supply continue to increase, making intelligent use of existing infrastructure is becoming increasingly important. The partnership between Saxovent Renewables and HIH Real Estate provides a framework for doing so and is intended to be extended to several locations in the future.

Growth capital for scaling solar power on commercial rooftops – hellgrün quadruples revenue in the million-euro range.

Berlin, January 20, 2026 – We are further increasing our stake in the Cologne-based energy startup hellgrün and providing additional growth capital to scale photovoltaic projects on commercial properties. As part of the follow-up financing, Saxovent will become the largest shareholder of hellgrün alongside the founding team.

hellgrün enables the cost-effective implementation of on-site PV and direct power models on commercial rooftops – especially for retail, logistics centers, cold storage, and manufacturing industries. The company manages the entire process, from site assessment and financing to construction and long-term operation.

The reason for expanding the commitment is the strong operational development: hellgrün quadrupled its revenue in 2025 in the million-euro range. From Saxovent’s perspective, this dynamic confirms the scalability of the model and the market demand in a segment where property owners and asset managers are under increasing pressure to pragmatically address ESG requirements and energy costs.

We are expanding our photovoltaic portfolio with a construction-ready ground-mounted project south of Rostock

Berlin, 5th December 2025 – Saxovent Renewables GmbH & Co. KG has acquired a solar park in Mecklenburg-Vorpommern from Milvio Energy GmbH. The construction-ready ground-mounted project, with a planned capacity of around 81.8 MWp, is located south of Rostock. It has an existing EEG subsidy for 20 MWp and offers additional potential for the integration of a battery storage system.

By taking over the project, we are not only strengthening our presence in northern Germany but also significantly expanding our PV portfolio.

• Saxovent Renewables acquires an 81.8 MWp solar project with partial existing EEG subsidy and additional battery storage potential
• The project will now be swiftly brought into construction and operation by Saxovent Renewables

The area of roughly 57.8 hectares on which the solar project is planned is leased from an agricultural enterprise for which innovation and sustainability are core guiding principles. A portion of the solar power generated in the future is intended to support the farm’s energy concept.

Further step in expanding the regional portfolio and agri-PV expertise – strengthening the project pipeline and deepening of the northern strategy

Berlin, 4th August 2025 – Saxovent Renewables has signed an agreement with Orrön Energy’s project development subsidiary to acquire an agri-photovoltaic project with a planned capacity of 76 MWp. Located in north-eastern Germany, the project is designed as an agri-PV plant that combines solar power generation with agricultural use.

• The 76 MWp project in north-eastern Germany has been acquired from Orrön Energy, securing a strategically important location for agri-photovoltaics early on.
• The combination of solar power generation and agricultural use is planned, with sustainable land use being key to achieving greater acceptance in the region.
• This is a further step in the expansion of the regional portfolio and agri-PV expertise, strengthening the project pipeline and the targeted deepening of the northern strategy.

The project fits seamlessly into Saxovent Renewables’ growth strategy of continuously expanding its portfolio in all key market areas, both organically and through targeted acquisitions. By entering the agri-PV sector, the company is promoting a partnership-based approach that fosters equal interaction between all parties involved.

By acquiring this new agri-PV project, Saxovent is expanding its development capabilities and strengthening its regional presence in north-eastern Germany. In addition to its relevance to the energy industry, the project offers opportunities to cooperate with agricultural businesses, local authorities, and regional service providers, in line with Saxovent’s northern strategy, recently reinforced by the new Hanover location.

Strengthening regional presence and expanding activities in the photovoltaic sector

Berlin, July 7th, 2025 – The Berlin-based renewable energy full-liner Saxovent Renewables is continuing its growth strategy and has opened a new location in Hanover. By expanding its regional presence, Saxovent is responding to the increasing importance of northern Germany for project development in the photovoltaic sector – particularly for rooftop and ground-mounted systems.

• New location strengthens operational base in the north – focus on project development of PV systems
• Strategic addition to the Berlin and Oldenburg sites – future-oriented expansion planned along the value chain
• Establishment in the traditional Bahlsen building on Lister Platz – modern workplace for 15 employees

In the new office on Lister Platz, housed in the modernised Bahlsen factory building, around 15 employees from the areas of project development and planning will work and contribute their expertise. In the medium term, the site is to be further expanded and developed into the leading development centre for photovoltaic projects within Saxovent Renewables. The location thus specifically complements the existing branches in Berlin and Oldenburg.

In addition to project development, several subsidiaries of the Saxovent Group are also represented in Hanover, enabling synergies and an interdisciplinary exchange on site. With the recent acquisition of the 13.6 MWp portfolio of the insolvent Fellensiek Group and the takeover of an experienced project team, Saxovent Renewables is not only further expanding its operational clout in the PV sector – Hanover also forms an important interface in terms of personnel for the successful integration of the new colleagues.
