B Capital Partners AG advises German institutional investor on its investment into a German fibre-optic platform

Investment with growth potential

B Capital Partners AG has advised German institutional investor on its co-investment into the Deutsche Glasfaser Group alongside the Canadian pension fund OMERS

Fibre-optic networks are part of the systemically relevant core-infrastructure of any country. Up to now, the nationwide coverage of fibre-optic networks in Germany is low in international comparison. The majority of existing networks is located in urban areas. Smaller cities and rural regions are significantly underserved. With its investment into Deutsche Glasfaser Group, the institutional investor advised by B Capital Partners therefore decided to go with an established player in the market, which focuses on non-metroplitan areas. This investment gives the investor the ability to participate in the growth in these regions.

This transaction allows the investor to complement its infrastructure portfolio with an additional investment that has stable cash-flows and an attractive risk-return profile.

B Capital Partners in its role as investment advisor has secured the access for the investor to this exciting co-investment opportunity with OMERS and has taken care of all aspects of the transaction from due diligence throughout to execution. On the legal side, the investor was advised by Allen & Overy.

B Capital Energy Transition Infrastructure Fund Finalises Acquisition of a German 10MW-Wind Farm

B Capital Energy Transition Infrastructure SICAV-SIF, a Luxembourg fund initiated by B Capital Partners AG, has completed the acquisition of a 100% equity stake in the German SPV “Ravenstein”, owner of four wind turbines located in Baden-Württemberg, with an overall installed capacity of 10 MW. The wind farm generates over 20GWh of electricity annually, equivalent to the yearly consumption of ca. 5,000 households. The wind farm avoids CO2 emissions of ca. 17,700 tons p.a.

This transaction allows B Capital to further diversify the portfolio of its fund by adding a German feed-in premium wind farm. B Capital has a long history of investing and managing low-risk, core assets in general and onshore wind farms in particular, having transacted ca. 280MW of capacity, the majority of which in Germany with 20-year feed-in tariffs. Along these lines, in January of this year, the fund invested in 26 operational run-of-river hydro power plants in Norway.

GRESB and B Capital Partners AG release open source ESG due diligence tool for Infrastructure Assets

GRESB and B Capital Partners AG announce the release of their stand-alone, open source ESG due diligence tool (>> ESG DD Tool) for infrastructure assets, which enables investors to gain a clear understanding of the ESG risks and opportunities of an asset as an input to investment decision making. Investors have been searching for guidance, transparency and quality in this area. This new ESG DD Tool helps establish a standard ESG due diligence process for infrastructure investing. For the purpose of the ESG DD Tool, the GRESB Infrastructure Assessment for benchmarking assets has been adapted to reflect the requirements of the M&A/Investment process.

Investors typically face the following challenges in ESG due diligence:

  • lack of a structured process to identify all potential ESG factors
  • difficulty in identifying the material ESG factors for any given asset,
  • quantification of the (material) ESG risks and opportunities, which can make or break the business case of an asset.

The new ESG DD Tool addresses these challenges head on. It will enable investors to reduce, mitigate or control potential (material) ESG risks, improve the overall risk/return profile of an asset and maximize long-term investment returns.

Invitation to provide feedback

The ESG DD Tool is open source. We invite the infrastructure and investment industry to provide feedback. GRESB and B Capital Partners will update the tool in response to feedback. Being Excel based, the tool can also be readily adapted by the user to meet his/her own due diligence needs.

Completed Divestment of a European 93MW Renewables Portfolio

B Capital Partners AG announces that the last post-closing conditions for the sale of three portfolios of renewable energy power plants have been completed. A Swiss Pension Fund sold the portfolios separately to three buyers during 2019.

A 52MW wind portfolio located in Northern France was sold to ERG; a PV portfolio of 15MW at various Italian sites was divested to an English infrastructure fund and a 26MW British PV portfolio is now owned by a UK-based PV fund.

B Capital Partners has been mandated to undertake and negotiate the sales process up until closing. The Pension Fund is very satisfied with the result of the divestment process.

BC-ETIF TOR invests exclusively in sustainable infrastructure in the energy transition sector. The longstanding minority shareholder has decided to leave the energy sector for internal reasons.

enso hydro GmbH remains the majority shareholder. It is an investment company owned by Austrian investors and the German hydropower-investment fund DWS Access Wasserkraft Beta KG, which is the majority shareholder in, altogether, 26 hydropower plants in Norway, Austria, Albania, and Turkey. enso GmbH, a renown and experienced Austrian based hydropower developer manages the hydropower investments.

Wolfgang Kröpfl, CEO of enso hydro GmbH is looking forward to having found a partner with B Capital Partners AG, who is not only interested in hydro power in Norway but also stands for future growth and sustainable engagement in this market.

B Capital Partners AG has studied the Norwegian hydro power market for several years and has looked for a suitable opportunity together with a strategic partner. B Capital Partners AG is excited to have implemented the strategy via its new partnership with enso.

The medium to long-term goal is to further strengthen BoS’ market position in Norway and to grow its hydropower portfolio to 500GWh. The focus remains on the strategic development of the company, as already evidenced by a larger transaction with an investment group of several Finnish utilities.

GRESB and B Capital Partners pilot ESG Due Diligence Standard for Infrastructure Assets

GRESB and B Capital Partners AG joined forces to pilot an ESG due diligence tool for infrastructure asset investments with the goal to develop a standard process to improve both the quality and efficiency of ESG due diligence.

B Capital Partners developed a pilot ESG Infrastructure Asset Investment Due Diligence Tool using the GRESB Infrastructure Asset Assessment as a basis. The tool has two goals:

  • for GRESB to offer investors and managers a high quality, on demand ESG due diligence service, supported by its proven platform and processes, in the context of e.g. acquiring new assets or regular assessments of assets for revaluation in annual financial statements, and
  • contributing to an international ESG due diligence assessment standard by making the tool available as open source, encouraging feedback to improve it further.

It is only when the results of ESG assessments are integrated into the business case that they get the appropriate attention. Integrating ESG factors in the due diligence will help to better understand the business in general and investment risks in particular, which in turn enable investors to reduce, mitigate or control certain risks, improve the overall risk/return profile and maximize long-term investment returns. There is currently no internationally accepted ESG-assessment standard for the ESG due diligence of infrastructure assets. This leaves investors to largely judge for themselves what they want to integrate in their evaluations, how to find the data for it, how to quantify the risks and opportunities, and how to publish and use the results.

In order to address this problem, B Capital Partners and GRESB conducted an ESG-due diligence pilot on the basis of 10 plus years of infrastructure due diligence experience. During the pilot, the GRESB Infrastructure Asset Assessment was modified to reflect the change of focus from benchmarking to due diligence and adapted to a checklist form. The checklist supports the ESG due diligence process and ensures all ESG risks and opportunities associated with the asset in question are identified. The most material “red-flag” issues are then summarised in the “red-flag” report together with potential mitigation measures.

In the future, GRESB plans to integrate this service into its existing, proven platform for ESG Assessment. This will simplify and standardize the process of ESG due diligence for the entire industry – addressing the lack of specific ESG due diligence knowledge and resources among investors.

Features of the service are expected to include: online, on demand availability for data input, validation of the submitted data, constantly available “punch lists” and red flag reports, which point to the most material ESG findings, as well as scoring and benchmarking against GRESB’s ever growing database of infrastructure assets, and standardized reporting systems.

Once the ESG due diligence document is online, all participants of the infrastructure and investment industry are invited to use the open source standard. The feedback from the industry will be used to refine the methodology and lay the basis for a widely accepted and transparent ESG due diligence standard for infrastructure asset investments.

Going forward GRESB will build the Due Diligence Assessment into its online portal and offer this as an online support service.

In the meantime, please contact us if you have any comments or queries.
