Investment Thesis:

Greenbacker invests in and operates a portfolio of income-producing renewables and energy transition infrastructure assets and also manages a number of climate-focused investments funds, leading the transition to a clean energy economy.

Investment Overview:

Greenbacker's objective is to generate attractive risk-adjusted returns consisting of both income and long-term capital appreciation by acquiring, financing, and investing in renewable energy infrastructure projects and other sustainable infrastructure businesses. As an independent power producer (IPP) and investment management business, we function as both long-term owner/operators of our renewable energy assets and financial asset managers of our investments. Our goal is to make direct investments into real assets, specifically sustainability-focused assets and companies, and provide an avenue for investors to access these clean energy businesses that would otherwise only be available at an institutional scale. We pair our best-in-class investment skillset with our world-class technical asset management to ensure that we’re not only investing in the best possible assets but that we then operating them to the highest possible standard and, in turn, produce the greatest amount of renewable energy to power a sustainable future.

Company Differentiator:

1) Greenbacker invests in assets that are small and medium in size, as we believe that US power generation and consumption will continue to move toward a distributed generation model, rather than remaining reliant on singular monolithic power plants that are located far from the end consumer. This greatly cuts our competition. Further, most of our deals are repeat bi-lateral transactions and we have worked with some developers for a number of years, which results in a natural and larger pipeline.

2) Greenbacker’s in-house team of engineers and technical asset management staff provide unique and integral expertise to our origination and ongoing asset management, as well as significant cost savings compared with third-party vendors. This team is involved in the due diligence process and allows our deal team to evaluate a larger pool of deals. This team also provides world-class asset management, monitoring our sites and keeping the fleet performing to a top-tier standard.

Investment Example

Turquoise Solar is a 61 MW ground mounted solar site located in Nevada. Greenbacker acquired this asset in March of 2019 as a pre-operational, shovel ready, asset. Our technical asset management (TAM) team worked with the developer to bring the site online in December 2020. Turquoise Solar sells power to one of Apple's data centers and has a 25 year contract. This asset is a great example of the influence our TAM team has on origination and management of the portfolio. Much of the turquoise project is located on rocky desert terrain with steep slopes. Our team worked with the EPC contractor and design and engineer the site. They determined that it would be safest and most efficient to use a fixed racking system that has ground screw foundations that drill into the difficult terrain. This asset has produced more than forecasted since being turned on.

Investments systematically target companies where social and/or environmental impact is integral to the product/service being created:

Greenbacker only invests in renewable energy project companies and sustainable infrastructure development companies. As a result, environmental impact is core to the business model of all target investment assets and companies. 

Investments systematically include social and environmental sustainability practices in the due diligence process:

When making investments into renewable energy project companies there is no intrafirm consideration to take place. However, when our private equity structure invests in sustainable developers, the deal seeks to ensure that all portfolio companies comply with all applicable environmental, social, and governance requirements laid out in that fund's ESG policy. DEI is also strongly considered and promoted among portfolio companies. Fair compensation is important to GDEV and the team requires management and employee incentive plans in all equity investments.
