Since 2015, CleanCapital has focused on driving investments into clean energy, specifically middle market solar and energy storage, across the U.S. Over the past decade, we have deployed well over $1 billion in institutional capital, grown our company to almost 80 strong, and fortified an operating portfolio of over 370 MW across 23 states, one of the country’s largest portfolios of operating solar assets.   

Today’s clean energy landscape is ever-evolving amid policy changes and the growing demand for energy due to electrification, the escalation of AI adoption, and growing domestic manufacturing. To successfully navigate a path to energy dominance, an all-of-the-above energy strategy will be critical. Solar is one of the fastest – and cheapest! – ways to bring clean megawatts to the grid and to ensure every American has energy security. CleanCapital recognizes it’s not just the clean megawatts added to the grid, but what we as a company do beyond the megawatt. That is why we place importance on continuing to benchmark our sustainable activities beyond investing, building, developing, owning and operating solar assets. Starting in 2022, we have completed the GRESB (Global Real Estate Sustainability Benchmark) Assessment to track and improve our ESG metrics in alignment with industry standards. As part of our GRESB benchmarking, we conducted a materiality assessment of 45 different ESG topics to determine their relevance and risk factors.  

In our second annual GRESB Benchmark report, we discuss our most recent benchmark score and its additional findings, our successes, and how we plan to strategically hold ourselves accountable to our customers, investors, and the broader community as we continue to grow. 

The Highlights

Here are a few highlights from our 2024 benchmark looking at our 2023 calendar year:

We increased our portfolio size by 7% and increased our energy generation output by 47%. 

  • In 2023, CleanCapital was able to tap into the solar energy middle market and continue to strengthen our portfolio. After the acquisition of BQ Energy in 2022, we expanded our operating portfolio to several states – including New York and New Jersey. As a result, the amount of clean energy generated increased by nearly half and was enough to power over 2,000 homes.  

We maintained a score above 80. 

  • Although our score declined by 2-points from our 2023 benchmark, it was only due to a change in reporting and inclusion of new criteria. Overall, our score of 83 is in alignment with the peer average GRESB score (85). As we continue to improve our internal processes and reporting collection methods, we are confident our score will increase. reporting processes and collection. 

Emissions avoided increased by 57% from the previous reporting period.

  • As our portfolio grew, so did the amount of clean energy generated by our projects. Compared to our previous reporting cycle, the amount of energy generated by our projects helped to keep 87,970 metric tons of emissions out of our atmosphere. That is equivalent to driving over 220 million miles in a gas powered vehicle!

As the U.S. progresses toward energy dominance, it is up to the companies in clean energy to lead the way. At CleanCapital, we aim to continue to evolve our ESG practices, standard reporting, and energy generation in a way that is restorative and does not adversely affect the progress of our planet. We will continue to implement strategies, tracking, and reporting to better understand how CleanCapital can operate as a leader in middle market solar and energy storage, while creating a more energy secure future for Americans.
